Thermal bridging is a much talked about but little understood phenomenon in building design. Thermal bridges occur at all junctions in the building, as well as when penetrations of the thermal insulation envelope occur. Thermal bridges can account for 35-50% of overall fabric heat losses when standard values are used.
To reduce head loss through thermal bridging, Quinn Building Products has developed a bespoke set of junction designs, each with its own unique thermal bridging value calculated by an NSAI-accredited Thermal Modeller, in order to bring down any heat loss to less than 10%.
This guarantees zero mould growth risk, and using conventional construction methods combined with the range of Quinn Lite blocks, the use of the freely-available details can allow designers and contractors to more easily achieve compliance with Part L, and in some cases reduce the amount of renewable energy resources specified, ensuring significant capital savings.
The thermal bridging values for each junction are stored in the Y-value calculator (try out the Quinn Y-value Calculator for your project).
