Application & Benefits

Customers frequently opt for high-performance, energy-efficient windows, only to overlook the importance of proper insulation around window posts and door frames.

We see examples where clients go to the extreme of installing ultra-efficient windows but neglect the details.

This oversight is particularly common in new constructions, especially those incorporating steel supports in bay windows. Addressing this issue, we wrap these sections in a 10mm foiled Spaceloft Aerogel insulation, effectively eliminating cold bridges and preventing future mould growth.

Thermal Steel Wraps

Spaceloft Aerogel is the world’s lowest-density solid and most effective thermal insulator. The outstanding thermal properties of aerogels have been studied for decades.

The unique process integrates Spaceloft Aerogel into a fiber-batting reinforcement to create flexible, resilient, durable Spaceloft Aerogel blankets with superior insulating properties.

Thermal Bridging Report

Below are extracts of an example report on how Spaceloft Aerogel performs in a Thermal Bridging Test. 


The Contractor supplied constructional drawings of a wind post wrapped in Spaceloft aerogel, to be used in a corner construction adjacent to two window/door jambs. The purpose of this project is to establish the linear heat loss of the insulated wind post via thermal bridging analysis.


The thermal bridging analysis of insulated wind posts has been undertaken in accordance with EN 10211: 2007 and BR497, using Physibel’s 3D heat flow program, TRISCO v13, to obtain the linear thermal transmittance, ?-value. This value may then be used as a SAP entry for dwellings.
