Grade II* Listed Chapter House is a striking building sitting adjacent to the iconic St Paul’s Cathedral, it was designed by Christopher Wren and his son and built between 1712-1714.

The building was originally used as accommodation for the Dean and other members of the Chapter. However, after suffering severe damage during the Second World War it was refurbished in the 1950s into offices, and has since been viewed as the administrative heart of the Cathedral.

Recently Chapter House underwent a major revamp to bring it up to modern and ecological office standards. A key requirement was to improve the thermal insulation throughout the building, retaining the buildings heat and reducing energy bills.

As a specialist in the design, manufacture and installation of secondary glazing, Selectaglaze was specified as its tested products can reduce heat loss by up to 50%. This can be achieved by the bespoke fitting of the secondary glazing alongside the use of high performance seals.

A number of Selectaglaze slime line products were used to suit the various window styles and sizes. These units were mainly chosen as the units are discreet, and a reversible adaptation and are accepted by heritage agencies across the UK.

Over 120 units have been installed in six different colour finishes to match the existing frames.

Established in 1966 and Royal Warrant holders since 2004, Selectaglaze has a wealth of experience working in all building types, as well as an extensive range of products to suit all projects.
