Selectaglaze helps upgrade grade II listed Christchurh building

Selectaglaze recently played a large part in the renovation and transformation of a Grade II* listed deconsecrated church located in Christchurch. 

Having been used as B1 grade offices for nearly 40 years now, the building was bought by Greenhouse Sports Ltd in 2017, a sports coaching charity for young people. The charity was keen to renovate the building into a modern sports centre that facilitates them to extend their sport for development model into the community.

Latitude Architects was involved with plans for the renovation, which were undertaken in consultation
with Historic England. It was decided that with shops, residential areas and community buildings surrounding it, the building required better sound insulation. The current single pane stain glass windows did little to prevent noise, therefore, Latitude architects specified the use of secondary glazing to provide better sound insulation as well as improving thermal properties.

Secondary glazing on the room side of a building offers a sound reduction of 45dB when there is a 100mm-
200mm cavity between the primary and secondary windows. Secondary glazing also traps an insulating layer of air, which can diminish heat loss by up to 50%. In addition, the introduction of low emissivity glass, U-values of around 1.8 can be achieved and the use of high-performance twin seals helps to virtually eradicate draughts.

Selectaglaze was chosen for the treatment and scheduling of secondary glazing work to the windows. Selectaglaze was unphased by the challenging windows due to the large sweeping curved heads at high level. To enable exact measurements and a snug fit, a laser measurer was used to plot the arches to facilitate the manufacture of the units. The newly created mezzanine level cut the full height windows in 2 which left a void in all the reveals. To combat this, the 1 st floor glazing also acted as a guard to the void, which included 12mm toughened glass.

Selectaglaze manufactured and installed 88 units, which were a mixture of Series 42 fixed lights with curved and
standard heads, as well as Series 80 3HS contra sliding units. Some of the Series 80 were 1.9m (h) x 2.3m (w)
and weighed over 130kg when all assembled, so fixing points had to be checked for their strength to maintain
the integrity of the installation. The units came in 3 separate panes to enable manual handling and accessing the
specific areas for installation.
