Thermal Bridging
Thermal bridging occurs where the continuity of insulation within the property is interupted - i.e. at junctions and around external openings.
The more "bridging" in a property will result in greater heatloss, higher energy consumption for space heating and increased carbon dioxide emissions.
In short, by reducing thermal bridging will result in a lower Building Emission Rate (BER).
Currently, thermal bridging is dealt with in the current SAP calculations in two ways;
Repeating Thermal Bridging - This includes areas such as cavity wall ties, and is included in the the U-Value calculations for the thermal elements (walls, floors and roofs);
Non Repeating Thermal Bridging - This occurs at junctions (for example where the floor meets the wall) and where the internal and external surfaces of the building are bridged (i.e lintels over external doorways and windows).
How we can help
Under SAP 2005, non repeating thermal bridging is dealt with in the SAP calculations by stipulating if either accredited construction or enhanced construction details have been used in the construction, or no consideration has been given to bridging.
However, from 1st October 2010, the revised Part L1a of the Building Regulations 2010 have revised how thermal bridging is dealt with in SAP 2009, and we will be updating this page shortly.
Compass Energy Solutions can take your calculated thermal bridging (Ψ) values for each junction and bridge, and calculate the linear losses as well as the overall percentage thermal bridging for each property or property type.
By ensuring thermal bridging is kept to a minimum, the overall energy performance of the property will be improved, resulting in lower energy bills and potentially a better Code for Sustainable Homes rating!
What we Provide
We provide our clients with either an electronic or paper report including;
Report showing calculated linear losses for each junction / bridge
Overall thermal bridging (Y) value for each dwelling type
Comprehensive advice and support throughout the whole process
Please contact us and we will be happy to discuss any requirements you may have with your existing, and future projects.
