Secondary Window GlazingSecondary Window Glazing

Secondary window glazing is an effective way to improve the thermal efficiency of your home, reduce outside noise and draughts whilst retaining your original windows. This system works similarly to double glazing, trapping a layer of air or argon between two panes of glass and can be fitted as either fixed or removable. This is an ideal solution if you are unable to afford to replace your existing windows or live in a conservation area and cannot install replacements.

Various systems fall under the umbrella term of secondary glazing, with solutions ranging from sheets of plastic to panes of glass fitted within timber or uPVC frames. Ultimately the best option is always to discuss your needs with a specialist as there are a number of different options available to suit any property.

Enhancing Comfort and Efficiency: The Benefits of Secondary Window Glazing

DIY secondary glazing systems are relatively easy to install, ranging from acrylic sheeting that can be cut to size and stuck in place with magnet strips, to pre-made windows that are screwed into the frame. Many of these systems are also relatively cheap and can be easily removed in summer to allow full use of the original window (but they require dedicated storage space).

While cheaper than professionally fitted products, it’s worth noting that DIY secondary glazing can often result in condensation on the inner face of the window, particularly where the gap is exposed to sunlight or moisture. It can also be difficult to install, especially for those who don’t have a good grasp of basic carpentry skills. Additionally, these systems may not offer the same level of acoustic performance or energy saving as more sophisticated options.
