Energy conservation is a growing concern in the current climate and is mandated by Approved Document L of the Building Regulations.

We carry out calculations for U-values by thermal simulation and calculation using THERM simulation software for compliance with the conservation of energy requirements of Document L of the building regulations. Our trained thermal simulators can also generate window energy ratings for the BFRC energy rating scheme.

Standards we test to:

• BS EN ISO 10077-1 Thermal performance of windows doors and shutters - general
• BS EN ISO 10077-2 Thermal performance of windows doors and shutters – numerical method for frames
• BS EN 673 Calculation of thermal transmittance of glazing
