Design review

If you already have a preliminary design for your project, we can offer advice on how best to approach detailing of the thermal envelope. We offer design and detailing of thermal bridge free junctions, window and door installations and airtightness strategies. Our team are able to specifit the most economic materials and methods to optimise your project’s performance.

Reducing thermal bridging "D Thermal Bridge Analysis

Reducing thermal bridging

Thermal bridges in highly insulated buildings contribute an additional heat loss from a building’s fabric of up to 30%. Let our team of experts design out any thermal bridges at the drawing board, using 2D Thermal Bridge Analysis.  We carry out detailed analysis, using specialist software, to ensure problematic junctions have minimal impact on thermal performance and safeguard against condensation and mould growth issues.

Avoiding moisture issues

Moisture build-up and interstitial condensation are a growing concern for retrofit and even newbuild projects. We now offer specialist WUFI hygrothermal modelling to offer you peace of mind that your project is going to achieve the standards you expect and ensure that the building fabric is not at risk  from moisture issues.

We are also able to advise on the most suitable building materials to avoid problems with moisture build-up, for example internal wall insulation for retrofit projects.
