Older, ill-fitting frames and thin glass leads to draughts and a real lack of thermal efficiency.
Owning a listed property and being subject to various planning restrictions shouldn’t preclude you from making your home more energy efficient.
Our bespoke secondary glazing is virtually invisible, so does not contravene listed restrictions, and our magnetic system helps create a thermal break preventing cold transferring from the primary glazing.
Under the instruction of Historic Scotland’s Technical Conservation Group an independent test was conducted by Paul Baker of Glasgow Caledonian University to discover the performance of traditional windows.
The table below summarises the results of the research on the thermal performance of traditional windows through the installation of Storm Windows bespoke secondary glazing and the thermal image clearly shows the heat loss through the primary glazing before secondary glazing is installed and after secondary glazing is installed.
We use toughened safety glass as a standard but we can also improve thermal efficiency even further by glazing the units with Pilkington K glass. This has a hard coating on one side of the glass which reflects heat back into the room achieving optimum thermal performance.
Accurate measuring by our fitters and precise glazing by our skilled craftsmen ensures that our secondary glazing fits exactly, even in irregularlyshaped frames.
