What not to use when cleaning windows and doors

In a previous article, we discussed how to clean your conservatory and offered a few tips on how to get the best results.  In this article, we’re going to look at the things to avoid when cleaning windows and doors in order to prevent damage occurring or unsightly results from your cleaning.

Cleaning the Window or Door Frame

When cleaning windows and doors, product choice is vital:

Don’t: use abrasive pads, bleach, spirits or everyday household cleaning products such as spray foam. Abrasive pads will damage the fabric of the frame while cleaning products, many of which are corrosive can cause discolouring to the uPVC frames.

Do: Use soft cloths and warm water. With regular cleaning, this will be more than enough to keep your window and door frames looking spotless.

Cleaning the Hardware (Including Weather Strips)

Any damage to the hardware is likely to affect the proper function of your windows or doors. Regular maintenance is, therefore, key to keeping the mechanism effective.

Don’t: use regular oil or grease or non-specialised lubricants. These can leave residue and may also cause damage to the surrounding areas, including weather strips.

Do: Use machine oil. This can be sourced from any good DIY store.

Cleaning the Glass

There is nothing worse than the light on a sunny day being ruined by grimy double-glazing. However, improper cleaning technique can make the problem worse and may even damage the glass.

Don’t: Use abrasive pads or glass cleaners. Abrasive pads will likely cause irreparable damage to the glass, while glass cleaners may cause runoff which will cause damage to the frame.

Do:  Use warm water, a soft cloth and non-abrasive, non-alcoholic cleaners. With regular cleaning, this will be enough to keep your windows sparkling, with minimum effort.

When it comes to cleaning windows and doors, the key thing is to make it regular. The build-up of grime on the frames or glass will lead to a more intensive clean being required, in which case it is best to engage a professional, rather than resort to potentially damaging elbow grease.

How to clean a conservatory roof

Conservatories are a fantastic addition to any home, providing stunning views as well as increasing the value of your home. But like the rest of your home, conservatories require some maintenance to keep them looking brand new. Due to the structure, many people aren’t aware of how to clean a conservatory. Or if they even can.

In this quick guide, we’ll cover all you need to know on how to clean a conservatory roof.

Safety first

When cleaning conservatories, safety is paramount. Whilst it is possible to clean a conservatory with the correct equipment and procedure if you lack either of these it may be best to consult a professional.

Safety rule number one with cleaning conservatories is not to? place your full weight onto the roof. Conservatories are not designed to support the weight of a person. As such they should never be climbed upon, as you risk serious injury.

Recommended equipment

Whilst a pressure washer might seem like the ideal tool for this cleaning tasks, pressure washers can damage the weather seals.

Instead, opt for:

  • A water-fed pole with a brush
  • A suitable cleaning detergent (safe for glass)
  • Squeegee
  • Gloves
  • Ladder
  • Bin bags

How to clean a conservatory

Set up a ladder in a safe position with access to the roof. Once you have access to the roof, clear the area of the larger debris such as leaves and moss by hand. Never step on the roof to access the higher areas of the roof.  Place the pieces of debris in a bin bag for easy cleaning later.

Once the larger debris has been cleared, apply a detergent and leave for 5-10 minutes to allow it to soak into the thick layers of dirt.

Using a water-fed pole begin to wash away the detergent. The small pieces of debris will be in the gutter so once again it is advised to clean the gutter by hand so that it doesn’t block drainage.

Complete a final rinse of the roof to ensure that all debris and detergent have been cleared, then leave to dry.

How often should you clean your conservatory?

There is no rule on how often you should clean your conservatory but under two conditions it would be advisable:

  1. After heavy rainfall clear the drain covers to make sure there’s no debris buildup, ensuring proper water flow. This reduces the buildup of grime on the windows.
  2. When visibility is reduced.

Whilst preventing drain blockages completely isn’t possible, you can make it more manageable. Investing in drain covers will help to prevent the need for regular unblocking.

Cleaning your conservatory will help you to enjoy stunning views of the sky and also allow you to increase the amount of sunlight in the room.

How double glazed windows improve thermal efficiency

Though double glazing has become more common in recent years, as well as being standard for most new builds, there are still a great number of homeowners in the UK that have yet to replace their old single glazed windows.

In this article, we’ll be taking a look at how double glazed windows function to improve the energy efficiency of your home.

How double glazing works

With a single glazed window, one glass pane serves as the barrier between your home and the outdoors. As we will talk about later, this is inefficient due to the heat conducting properties of glass.

Double glazing, on the other hand, uses two panes. Not only that, the layer of air between these sheets plays just as valuable a part in insulating your home as the extra glass.

This is also the case for the window frame. Unlike with single glazing, double glazed window frames provide more space to include an insulating framework. Including airtight seals with air chambers throughout. As we’ll talk about next, these pockets of air are highly beneficial.

Why is Double Glazing more effective at insulating your home?

As glass is a fantastic conductor of heat, single glazed windows do very little to prevent the transfer of heat. Whether it’s going in or out. This will mean that you end up overspending on heating and energy bills in the long run.

Double glazing is effective because whilst glass is a good conductor of heat, air is not. The air pocket between the two panes of glass, therefore, creates a seal against the outdoors. This reduces the transfer of heat. Some double glazed windows can even be filled with gases that conduct heat less well than air, such as Argon and Krypton. These increase the cost slightly but improve energy ratings even further.

What about triple glazing?

Whilst triple glazing is an option, it can be prohibitive in terms of cost. Potentially up to two times that of a double glazed window. As well as this triple glazed windows are noticeably larger than double glazed units. This is due to the large frame required to house the extra panel of glass. Meaning that you’ll have less range of motion when opening and closing your window. Plus, the extra frame may have an intrusive amount of overhang which could interfere with the furniture and fittings surrounding it.

Though Triple glazing may seem like a logical choice, the extra investment may not be worth it. In much colder climates such as Finland, where triple glazing is common, the extra protection is a necessary cost. For the UK’s milder climate, however, this is not the case.

If you’re looking for high quality double glazed uPVC windows, our Liniar window systems provide unbeatable energy efficiency and a wide range of customizability options.

Beating the summer heat – How certain window and door types improve air flow through the home

Continuing on with our topic of beating the summer heat, in this week’s article we’ll be looking at the kinds of windows that are best suited to creating greater airflow through the home. Any client that asks how to make their home cooler should be aware of the affect poor airflow has on the heat of a home.

So what causes poor airflow

One of the most common culprits of poor air flow is the mistake of only opening a single door or window as an inlet. To create proper air flow through the home you need both an intake and outlet. Opening windows at opposite ends of the home will provide this.

As well as this, advise customers to make sure there are no obstructions. This includes internal doors, or even the fittings on your windows, such as a curtain. These small diversions to air flow can make large impacts on how much cool air is circulating through your home.

Keeping secure

Although opening your windows is a great way to create better airflow throughout your home, you should always make sure to keep secure when doing so. Never leave your windows or doors unopened when you are not in the house. If you have a window open in a room you are not using, whilst in the house, consider using some safety precautions. We have plenty of bespoke solutions available.

Can your Window and door choices help?

Whilst all windows can aid with better airflow, if a new set is required and proper airflow is a concern, there are certain models better suited to it.

The Tilt & Turn is both elegant and secure, but in this case specifically, the utility of the Liniar Tilt & Turn is where it really shines. The uPVC Tilt & Turns wide range of motion make it unbeatable when it comes to directing air through your home. In the case of doors, both the Liniar bi-fold and Liniar French door are best in class when it comes to providing a cool breeze through the home.

Will my windows get damaged if I leave them open all the time?

Unlike wooden or aluminium frames which over time will suffer under the elements, our Liniar uPVC windows and doors don’t warp under the pressure. We even provide large insurance periods for warping and cracking, so we’ve got you covered.
