A major factor in the performance of the building fabric is not simply the amount of insulation you install, but how it interconnects with other building materials and the other insulated elements within the design / installation.
Non-repeating (linear) thermal bridges are most commonly caused by discontinuities in the building envelope and can appear around openings such as windows and door openings, around loft hatches, rooflights, internal walls and floors junctions.
Good insulation and control of air infiltration are essential when trying to achieve low energy and low heat loss in new builds and retrofit buildings. Specific attention to detailing is necessary during installation for insulation to work effectively and to ensure unwanted air infiltration is eliminated as far as practicable. However, the work doesn't stop there. It is very common for the thermal seal in the insulation layer to be overlooked and performance is simply, and inaccurately, assumed.
As of June this year, building regs Part F, L, O and S were brought in or updated as part of the transition to the government’s Future Home Standards in 2025.
