The sound alternative to window replacementIn all these cases secondary glazing can be a sound alternative to window replacement. It keeps the warmth in, dramatically reduces sound levels, retains the character of the original windows and, as a reversible adaptation, is acceptable to both Heritage bodies and Conservation Officers. Selectaglaze secondary glazing systems incorporate efficient seals to almost eliminate draughts and when glazed with low emissivity glass will reduce heat loss by up to 65%. This lowers running costs, improves comfort levels throughout the room and assists with carbon reduction objectives. Replacement is generally a first option but this may not be practical in leasehold flats and mansion blocks, frowned upon in conservation areas, impossible for Listed buildings and unsatisfactory if your home suffers excessive noise; all too common in our crowded, 24 hour society.
QuieterBespoke and well fitted secondary glazing offers the most effective noise insulation and will significantly outperform normal double glazed windows. The additional secondary window frame is generally fitted 100-150mm away from the primary window and the wide air space works to limit noise transmission across the panes.
Laboratory tests demonstrate that Selectaglaze's systems fitted in this way are capable of reducing noise levels by 42-45dB and even higher levels if a heavier glass is chosen. As a home owning nation we all want to make the most of our properties by improving the look and performance wherever we can. Windows can be the soul of a building and often the reason why we were first attracted to them, especially on more traditional properties with their very individual and sometimes ornate styling. Whist they may look good, these windows do not perform to our modern expectations and usually need a makeover to retain their kerb-appeal.
