The Old School in Ashford, Kent, is a Grade II Listed property that delivers housing through the SAHA. The building was in need of upgrading as the thin cavity double glazed windows were draughty and unable to retain the heat efficiently. Creating a suitable solution for this required some consideration, as the primary windows could not be replaced.
However, a solution was found with Selectaglaze secondary glazing which is fitted to the room side of the window, is a reversible adaptation and accepted by most heritage bodies.
Many of the windows were shaped with gothic style curves and trefoil, which presented Selectaglaze with an interesting challenge. The use of a 3D digital measuring device allowed the openings to be modelled with precision which enabled the best possible fit for the bespoke designed units. This together with high performance seals helped to virtually eradicate unwanted draughts and provide a more comfortable living space for the occupants.
An added benefit of secondary glazing is the reduction of outside noise. When there is a 100mm cavity between the primary and secondary windows a sound reduction of about 45dB is achievable.
More than 100 secondary units were installed using five different Selectaglaze products, all in the slim line range which are ideal for heritage projects. They introduce minimal sightlines and are designed to be as unobtrusive as possible.
Selectaglaze has a wealth of experience working on all manner of building styles, from Listed to new-build. Established for 50 years and Royal Warrant Holders since 2004, it has an extensive product range to suit most buildings to aid in making them; warmer, quieter and safer.
