Icynene Spray Foam insulation for new Baptist Church in Dumfries


insulation specialists, Icynene to solve a complex insulation challenge. The new Church is a 2000sqm, multi-purpose building designed by Glasgow based, McLean Architects and built in the Georgetown district of Dumfries in the Scottish Borders. The building was conceived as a flexible-use community hub comprising worship, conference and youth facilities together a full specification games hall and multi-use games area. For the games hall, McLean Architects designed an 18.00x 18.00msq 8.00m high structure comprising a 140mm thick internal leaf of concrete blockwork with an external steel frame, supporting fibre-cement rain-screen cladding. Here, the placement of insulation between

made it extremely difficult to install conventional rigid board insulation. It would have been a hugely labour-intensive and expensive process and achieving the required air tightness standards would have been pretty much impossible”


Spray foam insulation


Icynene was sprayed directly onto the blockwork and over the concealed sections of cladding framework.


Specialist insulation contractors, JSJ Foam Insulation Ltd, who were brought in by main contractors Ashleigh Building of Dumfries, recommended Icynene, a high-performance spray foam insulation system which would be applied directly to the outer face of the blockwork, then covered by the cladding. Icynene is a predominantly water blown insulation which is applied using a pressurised gun system. Foam is applied as a two-component mixture that comes together at the tip of a gun forming a foam that expands 100-fold within seconds of application, sealing all gaps, service holes and hard to reach spaces, virtually eliminating cold bridging and air leakage.


Air leakage can cause up to 40 per cent of


heat loss from a building and traditional forms of insulation are relatively inefficient in
