Thermal
The hot topic in construction and current news is the drive to lower carbon emissions and reach Net Zero.
TimberTight is committed to supporting our clients in meeting these key goals. We work with you to find the best way to meet your project's fabric efficiency target. This target focuses on minimising heat loss through the building’s structure and insulation.
Building Regulations & Energy Performance
The Approved Document L sets out the minimum standards for heat loss and energy use in buildings. Every new building must undergo a Standard Assessment Procedure (SAP), which evaluates fabric heat loss, energy usage, and more. Upon completion, you’ll receive an Energy Performance Certificate (EPC) indicating your building’s energy efficiency rating.
Our Expertise in Fabric Efficiency
At TimberTight, we have in-house capabilities to calculate U-values and thermal bridging details (Psi values). We also offer various solutions to achieve optimal building air-tightness, all of which feed into the SAP assessment.
How We Target Heat Loss
TimberTight U-Values
A U-value measures the rate of heat loss through the fabric of the building, expressed in W/m²K. We calculate U-values by adding together the thermal resistance of the materials within each building element.
We can provide project-specific U-values for walls, roofs, and floors, ensuring your project meets performance standards and optimises energy efficiency.
TimberTight Air Tightness
As part of the SAP assessment, an air tightness target is set. This is measured in air changes per hour (ACH) at a 50 Pascal pressure difference between the inside and outside.
The Principal Contractor oversees air tightness, but TimberTight can provide the necessary details to help meet the target.
TimberTight Thermal Bridging
Thermal bridging occurs when heat escapes through the junctions between building elements. Psi values measure the heat loss at these junctions and are calculated in W (m.K).
TimberTight’s software and expertise allow us to calculate and optimise these values, ensuring your project’s junction designs meet the SAP assessment criteria.
TimberTight Fire Testing
In addition to achieving lower U-values, TimberTight is investing in research and development to test new wall designs that comply with Building Regulations Approved Document B - Fire Safety.
We have test data for plasterboard fixed to internal service battens and are continuously exploring new solutions for safe, energy-efficient construction.
