Thermal bridging in energy efficient buildings

A thermal bridge is created where materials that are relatively poor insulators are in contact across an insulation barrier. This creates a low resistance path for heat to escape from in an otherwise well insulated construction.   Limiting thermal bridges is becoming increasingly important with higher environmental standards such as Code Level 4 and the [...]

Specification of MVHR to improve performance in SAP

Mechanical Ventilation with Heat Recovery (MVHR) systems are balanced whole house ventilation systems. As well as exhausting air from wet rooms like typical extract units, they also preheat the incoming air for diffusion into living spaces. MVHR is increasingly being specified by house builders. In many instances this is because it can make a significant [...]
