Window and door hardware you can trust

Your home is your pride and joy, so keeping it secure is one of your main priorities. That’s why when it comes to updating your windows and doors, you need to be sure that the hardware and locking systems are going to keep your house and all your belongings safe and secure.

It isn’t uncommon to have a new window fitted and then find, after a year or less, that they are loose on their hinges. As a homeowner, this is both concerning and annoying, which is why you’ll need to find a supplier who puts care into every part of their product.  

The importance of good window and door hardware

Security is one of the most important factors when choosing a new uPVC window or door. It’s more than just the style and configuration you’ll need to be thinking off, as any product designed to provide security is only as good as its weakest link. So choosing a frame that has no weak links is paramount. As well as the locking mechanism, you need to make sure that hinges and handles are of the highest quality.

At the Double Glazing Network, we are committed to making sure every part of your new windows and doors are of the highest standard, which is why we partner with the leading brands for window and door hardware.

Finding the right window for your home

We know that having new windows installed into your home is a long term investment, and therefore choosing the right frames for your home is a big decision. We want to help you as much as possible to make the decision that is right for you and your property.

In today’s article, we’ll take a look at the benefits of updating your windows and the different styles we offer, which you will need to consider before making your purchase.

Benefits of new windows

New windows are great for bringing a new lease of life into your home. Whether you’re in the market because your old windows are due to be replaced, or are thinking of upgrading to improve the aesthetic or thermal efficiency of your home, we have the right windows to help transform your home.

If your windows are on the older side, not only will new windows look better, but will also provide improved security and energy efficiency, with the added benefit of being more environmentally friendly. This is due to advances in uPVC technology, spearheaded by our uPVC manufacturing partner Liniar.

These added benefits will not only improve the heating in your home and make you and your family feel safer, but it will also help to lower the cost of your home insurance.

Window styles

Now that you know some of the benefits new uPVC windows can bring, let’s take a look at some of the available styles.


Casement windows feature two sides which can be open and closed independently and are one of the most commonly used and recognisable uPVC window styles. As well as being classically stylish, Casement windows are also incredibly secure and versatile.

Flush Sash

Our Flush Sash windows provide all of the aesthetics of a traditional timber frame whilst also offering greater thermal efficiency, security and with little to no maintenance requirements.

Available with endless customisability combinations, our Flush Sash uPVC windows fit seamlessly into any home.

Sliding Sash Windows

If you’re looking to upgrade your windows whilst also preserving the existing character of your home the Sash Horn and Sliding Sash windows are fantastic choices. With their silky smooth operation, you will no longer need to worry about your windows sticking.

Like all of our windows and doors, our Sliding Sash windows are completely free of lead and are 100% recyclable. No matter the time of year, Liniar Sliding Sash windows keep your home safe from the elements.

Tilt & Turn

Tilt & Turn uPVC windows are highly versatile and functional, allowing for the greatest range of movement of any window type.

Tilt & Turn is a great option if you’re looking to improve the ventilation in your home. The ability to position the window into a tilt only angle allows fresh air to be circulated whilst also keeping your property secure. They also provide easy cleaning functionality, banishing the awkwardness that comes with cleaning a traditional window.

Which window is best suited for your budget

Choosing windows that fit within your budget and meet your requirements can be difficult. If you are struggling, it’s worth thinking about what you need first and foremost.

Are you wanting to maximise the natural light in your home? Revitalise the look of your property? Or are you just replacing windows that are on their way out? Whatever the case, there’s a uPVC window for you.

If you’re still unsure about which window style is best for you, why not try out our window quote tool? Here you can make choices about the type and the style of window, right down to the accessories and colour. Alternatively, you can search for your nearest window installer.

What makes a secured by design window or door?

What is secured by design?

When it comes to the window and door security, the secured by design accreditation may be something you’ve heard mentioned. But what is it really? And why is it beneficial?

Secured by design is a police backed standard and specification for the design and manufacturing of products which make burglaries more difficult. These security standards cover a broad spectrum of applications and products including windows, doors and locking systems.

So how is having windows and doors that are Secured By Design accredited beneficial?

Secured by Designed Standard

The Secured By Design standard is an indicator that your windows and doors have been rigorously tested to the highest security standards. However, we don’t just carry out the initial test, we regularly retest our products to prevent any deterioration in product quality over time and ensure they continue to remain secure.

With up to an 87% reduction of burglaries in new homes, the secured by design standard is clearly effective at reducing crime and keep homeowners safe. As well as this, having secured by design window and doors frames can also reduce your home’s insurance costs.

Which DGN products are secured by design accredited?

As security is a key item on any homeowners priority list, it’s vital that your new windows and doors provide the best protection available. At the DGN we’re set on providing this assurance, so each and every one of our products is SBD accredited, from the hardware to the frame.

That’s right, every single one, which includes both our Yale and ATK locking systems as well as each of our Liniar frames. So whether you’re buying a bi-fold door or a flush sash window, you’re protected.

At the DGN we provide secure doors and windows to suit any home. With a 10-year manufacturers guarantee and more than 35 years of expected lifetime, there’s no better choice than DGN.

How do I choose the right door for my budget

With the new year in full swing, there’s no better time to think about making home improvements. If you’re looking to make a great first impression, a new bespoke door may be the ticket.

As our doors can come in an extensive range of styles, materials, and configurations we’ve put together this article to cover the range of doors we offer.


uPVC doors

uPVC doors generally tend to be the most cost-effective option for many homeowners. This is due to a construction that is more simplistic than its composite counterpart. But don’t mistake uPVCs simplicity as being indicative of poorer quality. Our Liniar uPVC frames are at the forefront of innovation, pushing the boundaries of thermal efficiency and security, as well as style.

If you’re looking for an energy efficient and secure door, uPVC has all of the benefits of a modern door at great prices. On top of this, uPVC doors are highly customizable allowing for nearly endless personalization.


Composite doors

Composite doors are usually a larger investment than most other door types, although there is good reasons for this. DGN composite doors combine all of the benefits of uPVC with a foam core for additional weatherproofing and shock absorption as well as a glass reinforced plastic outer shell, which is highly weather resistant.

Overall composite doors offer the best security and energy efficiency features available on the market and DGNs Endurance range is no exception. On top of this, our composite doors come with the same extensive range of customizability options available on our uPVC range, so you’ll never need to choose function over style.

What should you choose?

When it comes to doors, our advice would be to choose a door that provides you with the features you require and is within your budget. Whilst other door types are available, nothing beats the low maintenance requirements and fantastic feature set of uPVC and composite doors.

Sustainable Windows and Doors: Recycling old Frames

uPVC now represents the largest market share portion for windows and doors, when compared with traditional timber and aluminium frames. But what does that mean for sustainability? Are uPVC windows and doors recyclable and will they be processed accordingly?

There is a misconception that uPVC frames represent the less environmentally friendly option. In this article, we discuss the facts about recycling old Frames. Plus how, as a homeowner, you can help to ensure your old windows are being disposed of correctly.

Sustainable manufacturing

Liniar manufacture uPVC windows and doors that are completely lead-free. This makes them safer for your family and the environment. The uPVC manufacturing process also requires far less energy consumption, in comparison to alternative frame materials.

In addition, Liniar windows are the most thermally efficient windows on the market, which means your home will have lower running costs and greater fuel efficiency.

How to make sure your frames are recycled

If you want to be absolutely certain that your frames can be reused after removal, there are measures you should take. This will help to ensure that your installer is removing the frames correctly. When a surveyor checks your property, make sure all materials that must be disposed of or recycled are correctly recorded.

Additionally, check with the installer that they are sending the materials to the correct place. DGN installers only work with trusted plastic and glass recycling facilities, ensuring that no part of your window goes to waste.

How much of a frame can be recycled?

The question is, can uPVC frames be recycled? Unlike timber frames, which cannot always be recycled, all components of Liniar uPVC windows, including the glass, are recyclable. With up to 10 re-uses, the same materials can be in circulation for up to 300 years. Some of the benefits of recycling old frames are that they can be reused. This includes repurposing as piping, garden furniture or even as dental retainers.

As well as being the most thermally efficient window frame on the market, Liniar windows offer the most future-proof solution for your window installation.

How to find a trustworthy window installer

Finding somebody to install your windows and doors can be a tricky business. Even a recommendation is only as reliable as the person making it. The strength of a single job is also not always the best indicator of trustworthiness.

At the Double Glazing Network (DGN) we understand the importance of having someone trustworthy to do such significant home improvement on your house. In this article, we’ll discuss the most important factors to consider when looking for an installer and the simplest ways to find someone reliable.

What to look for in a window installer

There are many considerations when choosing somebody to install your windows and doors. The following will help to ensure that you have an efficient installation and achieve satisfying results.

Location: Where is your installer based? It’s all very well having an installer with rave reviews, but if they’re based 50 miles away, how quickly are they going to be able to get to you? It’s advised that you try to find somebody based locally to you. This will help to ensure they can be flexible and responsive in delivering the work.

Previous work: It’s essential that you get a good idea of what your installer is capable of. Ask to see examples of their previous work and ensure they provide you with quality images. You should also ask for references and see if they have any reviews on review sites.

Who are their suppliers?: Another critical element in selecting an installer is choosing somebody who uses quality products and, more importantly, products which match your requirements. A reliable installer is only as good as their team and their supply chain. A reputable installer should be able to tell you who their suppliers are and provide you with guarantees of their service.

Other tips

The easiest and safest way to do this is to use our online QuoteBuilder to create your bespoke window or door quotes and find a local installer. Double Glazing Network only works with trustworthy installers with a proven track record. You can also locate your nearest window or door installer here.

Can you paint uPVC windows and doors?

Whether your window and door frames are starting to look less than their best, or you simply want a new look for your home, it can be tempting to try and paint the frames. We take a look at whether you can paint your uPVC windows or doors and end up with a finish that will last.

Well in truth, yes, it can be done. However, done incorrectly, you can end up with frames that look worse than before. This is why most homeowners now prefer to take advantage of the range of styles and finishes on offer. However, if you do decide to paint your frames, there are some things you need to consider.

When painting

When painting onto a uPVC window or door frame, you will first need to use a uPVC paint primer. When buying a primer, make sure it is specifically designed for use on uPVC surfaces. Other primers intended for different surfaces will, unfortunately, not have the same effect.

The primer will help the paint to adhere to the surface and prevent the paint from running and streaking.

Common issues

uPVC does not allow paint to soak into the frame. So even with a primer, you will need to be very accurate in order to achieve a good finish. Over time, painted uPVC will also begin to crack rather than fade. This is because the uPVC frame will not flex or warp in the same way as the paint due to weather and age.

This may leave your windows and doors looking worse for wear. At which point you will need to carefully strip away the previous paint and reapply if you wish.

Alternative solutions

If you really want to spruce up the appearance of your home, our extensive range of styles and colours mean you can get the look you’re after without the need for paint. Even the addition of a new style of front door can make all the difference.

Planning Permission for Windows

For most homeowners, planning permission is a grey area. It can even prevent you from making the improvements you want to make to your home. Luckily, planning permission is rarely required when installing new windows.

However, there are a number of exceptions. Without due consideration, you may find your plans for new windows are scuppered before you even start. So before you engage somebody to install your new windows, it’s best to check first if planning permission applies.

When do I need planning permission for new windows?

Planning regulations vary depending on the local authority for your area, so it’s always best to make your first enquiries there. If you are in any doubt, you should also contact a surveyor to obtain an expert professional opinion. Are you trying to determine whether or not you need planning permission for your new windows and doors?

Our top tips follow.

Switching from a flat to a bay window

In this instance, you will need planning permission as you are altering the structure of your home, as well as the appearance. Care must be taken to ensure the loads are properly supported during and after the installation. Planning permission will be subject to a structural assessment conducted by a qualified engineer.

Do you live in a listed area?

If you live in a listed area, you will need to obtain planning permission before making any changes to the external aesthetic of the building, this includes changing your windows. Replacement windows will be required to be in keeping with the building’s existing appearance to ensure the area retains its current aesthetic.

Fire Safety

Newly installed windows must be equal to or greater in size than existing installations. This is to ensure emergency egress is possible in the event of a fire occurring. This is your responsibility as the homeowner so be sure to check with your installers that they are installing correctly.

It is your responsibility to be up to date with planning regulations in order to ensure your new home is compliant. However, a qualified and trusted installer will always guide on these regulations and make sure your installation is correct and legal. If in doubt, always contact a surveyor to guide you through the process.

How to minimise unexpected delays to window or door installation

The thought of having any large-scale home improvements fills many of us with dread. The big question being, how long is this going to take? And how much disruption will it cause? Whilst every company will provide an estimated timeframe, there’s always the chance that the unexpected will occur. Meaning you could end up being inconvenienced for far longer than you had initially expected.

So how can you minimise unexpected delays? Well, there are a number of things you can do. With this guide, we’ll teach you to minimise delays. Meaning you can enjoy your new home improvement as quickly as possible.

Get a schedule in writing

It’s a good idea before you start to get a schedule from your installer, in writing. This gives you the opportunity to make arrangements around the work being carried out. It also provides you with evidence of the installer’s intentions from the outset. It is also a good idea to establish a rapport with your installers to ensure there is good communication between you and the team. This will make them more likely to keep you informed of any potential delays, ahead of time.

Prepare the site beforehand

The more you can do to prepare the site, the quicker your installers will be able to get to work. This means ensuring halls are clear and work areas are free of furniture and other obstructions. Not only will this speed up the process, but will also go a long way to building a good relationship between yourself and your installers.

Use Quote Builder

Nobody likes to sit around waiting for a quote to be finalised. Delaying the start time could also mean you end up missing the nice weather and having to have your windows or doors installed in less favourable conditions. Thus leading to further delays.

By making use of our Quote Builder, DGN customers can reduce these delays and generate a bespoke quote in a matter of minutes. By providing key measurements and selecting from our extensive range of styles you can get a quotation built just for you.

Choosing the right time to replace your windows.

When is the best time to replace your windows? Really, the answer is the time that suits you best. You may prefer to have your windows replaced during the summer months when the weather is warmer and inclement weather is less likely to hold up progress. However, during the autumn, installers take fewer bookings, meaning they will be able to dedicate more time to your project and you can have your new windows installed before the winter weather arrives.

When you DO experience delays

When you do experience delays in the installation, the first task is to contact the project leader and seek an explanation for the delay. They will be able to give you an idea of how long it will take for the project to get back on track. Now is also a good time to refer them to the project plan they gave you up front.

Find a trusted installer

And finally, when you’re having your windows replaced, it’s always best to source an approved and trusted installer. Double Glazing Network members are all required to operate with a 7-10 day turnaround on quotes, so you know your window or door installation will always be underway without delay.

All you need to know about Composite Doors

In recent years, composite doors have become an increasingly popular choice with homeowners due to their great looks, as well as their structural and insulating benefits.

Today we’re going to be taking a closer look at composite doors and how they differ from uPVC, timber and aluminium doors. We’ll also be looking at the pros and cons of choosing a composite door over other materials, plus where to buy them.

What is a composite door?

Composite doors, unlike other singular material doors, are made up of several different components. Typically a composite door has three distinct material layers:

  1. An outer layer made of uPVC combined most commonly with galvanized steel, however, this can vary from door to door.
  2. Layer two is a second uPVC layer.
  3. Finally, the door’s core is made of a hardwood.

There can also be further insulating layers, to aid with thermal efficiency.

At the Double Glazing Network, however, we’ve taken this a step further. Our composite doors are made of 17 laminated layers! Making them 10% thicker than the average composite door. This all adds up to the Vista being one of the strongest and most versatile composite doors available.

That’s not all though. As with all DGN products, we commit to offering a huge range of styling options to suit any home. You can configure your very own Vista composite door to your heart’s content, using our quote builder tool.

So what are the benefits of a composite door?

Composite doors are first and foremost, incredibly hard wearing. Due to the reinforced materials used, the combined strength provided is unmatched. As a result composite doors are very difficult to break in to. Coupled with our multipoint locking system, would-be thieves don’t stand a chance.

Composite doors are also engineered to be extremely weather resistant. As such they are very thermally efficient, perfect for homeowners looking to lower their energy bills.

Much like a uPVC door, a composite door is low-maintenance. Although they may contain wood matter, it is as part of a composite layer. This means that it does not require the same type of maintenance as a regular wooden door would.

Are there disadvantages?

The one main disadvantage of selecting a composite door is the price. The meticulous construction of a composite door and the high-quality materials that go into creating one, increase the price. However, this price increase is well worth the added security benefits that the door provides. With all of the advantages, composite doors continue to become a more popular choice for homeowners.

At DGN we provide secure and efficient composite doors with style options to suit any home. With an expected lifetime of over 35 years and a 10-year manufacturers guarantee, you can’t go wrong.
