Secondary glazing is an excellent way to improve energy efficiency and help keep your home warmer and quieter. However, not all diy secondary glazing kits are of the same standard and it’s important to do your research before purchasing as you could end up with a poor quality system that doesn’t fit your window frame or is difficult to install correctly.

The basic type of diy secondary glazing involves sticking a transparent film over the existing window area which creates an insulating air cushion and helps eliminate condensation. These systems are cheap and easy to fit, but can have some drawbacks compared to professionally installed solutions. For example, they don’t offer the same level of heat retention and some varieties of acrylic secondary glazing can get ‘foggy’ after prolonged exposure to sunlight. Additionally, systems that need to be completely dismounted in summer may require regular storage which can add extra costs.

DIY Secondary Glazing Kits: Transforming Your Home with Ease and Affordability

The better quality diy secondary glazing kits are made from clear polycarbonate or clear Perspex(r) acrylic sheets. They can be fixed either by adhesive tape or screwing and are available in various options to suit your windows. Hinged secondary glazing can be opened like a normal window, and horizontal sliding systems allow you to open your windows at one side and close them at the other. They are also more suitable for conservation areas and listed buildings. These high-quality systems are more effective in preventing heat loss and improving thermal insulation, and they’re ideal for properties with single glazed windows. They also provide enhanced noise protection and sound proofing, which is why they’re often used in recording studios and music venues.
