I have developed a system of secondary double glazing that significantly improves the thermal and acoustic efficiency of single glazed windows. The frames are made form timber and individually designed,made and finished/painted for every installation. Contact me about a feasibility visit and a quote!
There are number of mass produced aluminium products on the market. While these can offer more alternative ways of opening the seconary unit, they are often bulky and obtrusive and can prove very expensive (often as much as replacing the whole window)! My installations cause minimum damage to the existing frame (usually just a few screw holes) and do not change the character of the façade, this makes it ideal for period properties and conservation areas. They are also a very cost effective alternative to the aluminium mass produced product.
I am not able to offer secondary glazing for every window, but I have created solutions for a large number of different window types from Georgian town houses to Dartmoor cottages. I have worked with listed properties and a National Trust property.·

glazing can give significant noise reduction. Noise
reduction of up to 80% can be achieved. Even in less than ideal instalation
situations, 50% noise reduction is almost certain.
It is also possible to fit glass of a different thickness in the secondary unit to that of the primary window. When the inner and outer glass have a different mass, higher frequency noise is reduced through the reduction of ‘sympathic resonance’. Using a thicker glass improves performance, particularly at lower frequencies. There are also a range of specialist glasses available to further reduce sound if necessary.
Living in a listed building or conservation area, means that replacing existing windows with double glazing is often not an option due to planning restrictions. Fitting internal secondary glazing is ideal as it does not require planning permission (with a very few exceptions).
