Robust Details

Robust Details

Robust details are details which show that the KeyBEMO® roofing system manufactured and installed conforms to those details set down by the current building regulations at all the required levels, which encompasses both thermal performance and air tightness.

The new Building Regulations April 2006 – Approved document L2 A and L2 B requires that the building fabric should be constructed in such a manner that there are no thermal bridges or gaps in the insulation layer and / or within the various elements of roof construction including the interfaces with other components

At KeyBemo® Limited we have had our “Robust Details” 3D Thermally modelled by the BRE (East Kilbride) to verify compliance with the requirement of approved document L2 A and L2 B . This testing established both the minimum factor (ƒ min) and the transition heat loss coefficient (ψ) which are shown on the various details. These valued are then utilised in determining the overall thermal performance of the building envelope and the “Robust Details” for its compliance with the air-tightness requirement (containment and heat loss prevention)
