LABC Registered Construction Detail

Thermal bridging can account for of heat loss within a home*, and as properties are being built with better insulation and energy efficiency targets are getting tougher, the importance of thermal bridging has increased.

Thermal bridging occurs in junctions where surfaces - such as around windows - have a much lower insulation value to the materials surrounding it, for example an external cavity wall. The obvious solution can be to increase the insulation of that surface, however, this is often not a viable option due to size disparities between both surfaces. So the best way of overcoming thermal bridging is to use construction details to design these cold spots out.

So, to make the Building Control process easier, Build Aviator has partnered with the Local Authority Building Control (LABC) to integrate a library of compliant products into all 368 Registered Construction Details.

With over 15,000 products inputted within the 368 construction details, the process for choosing compatible solutions to minimise the heat loss within the building envelope and complying with current building regulation has been simplified.


As standard, we provide all the relevant RCDs required for your build as part of our SAP assessment service.

Failing to address thermal bridging could be the difference between compliance or failure for your project.

Build Aviator is continuously developing additional construction details for alternative building methods such as timber frame, acoustics and renovations.
