Retrofitting Integral Blinds to Existing Double Glazed Windows – Is It Possible?

If you’re considering upgrading your windows with integral blinds, you might be wondering whether they can be retrofitted into your existing double glazed units. Integral blinds, which are sealed between the glass panes, offer a sleek and modern solution for controlling light and enhancing privacy. But can they be added to your current windows? In this blog post, we’ll explore the possibilities of retrofitting integral blinds and what the process involves.

What Are Integral Blinds?

Integral blinds are a unique window treatment option that sits between two panes of glass in double glazed units. This design offers several advantages:

• Maintenance-Free – being sealed within the glass means they are protected from dust and dirt, eliminating the need for regular cleaning.
• Enhanced Insulation – integral blinds can help improve the energy efficiency of your windows.
• Aesthetics – they provide a modern, streamlined appearance without visible cords or slats, making them an attractive option for contemporary homes.

Can Integral Blinds Be Retrofitted?

Yes, in some instances, integral blinds can be retrofitted to existing double glazed windows, although this is contingent on a few factors:

1. Type of Glazing Unit

Some manufacturers offer specialised systems that allow for retrofitting integral blinds into existing double glazed windows. This often involves replacing the current sealed glass unit with a new one that has integral blinds. If your existing windows have removable glazing panels, this may be a viable option, allowing you to keep your original window frames.

2. Spacer Bar Size

The width of the spacer bar (the area between the glass panes) is crucial. If there is enough space to accommodate the blinds, retrofitting is more feasible. If the spacer is too narrow, a full replacement will likely be necessary.

3. Frame Condition

The condition of your window frames also plays a role. If the frames are in good shape, retrofitting may be a practical solution. However, if they are aging or damaged, a complete replacement may be a better choice to ensure optimal performance.

The Retrofitting Process

If retrofitting is feasible, the process generally involves the following steps:

1. Assessment – a professional will evaluate your existing windows to determine whether they can accommodate integral blinds.
2. Removing Old Panes – the existing double glazed panes are carefully removed from the frames.
3. Installing New Panes – new double glazed units that contain the integral blinds are fitted into the frames.
4. Sealing – the new units are sealed to maintain energy efficiency and insulation.

Benefits of Retrofitting

Choosing to retrofit integral blinds offers several advantages:

• Cost Savings – retrofitting can be more affordable than a full window replacement, especially if the frames are still in good condition.
• Preservation of Existing Décor – you can maintain the look of your original windows while upgrading their functionality.
• Reduced Disruption – the retrofitting process is typically less invasive than replacing entire windows.

When Retrofitting Might Not Be Ideal

While retrofitting integral blinds can be a great option, there are situations where it may not be the best choice:

• Older Windows – if your windows are outdated or have poor energy performance, a full replacement may provide better long-term benefits.
• Limited Spacer Bar Size – if the existing windows do not have enough space for the blinds, replacement will be necessary to achieve the desired look and functionality.

While retrofitting integral blinds into existing double glazed windows is possible in certain cases, it’s essential to have your windows professionally assessed to determine the best course of action. Whether you choose to retrofit or opt for a full replacement, integrating integral blinds can enhance your home’s comfort, energy efficiency, and style.
