Technical Risks When Modifying Thermal Elements
When insulating thermal elements, designers must consider technical risks such as condensation in roof spaces and rain penetration in cavity walls, with reference to BR 262 for guidance on minimising these risks.
When modifying a thermal element (such as insulating a roof space or filling the cavity in a wall) it is essential to consider the technical risks that may arise. For example, condensation is a major risk in insulated roof spaces and roof ventilation may be essential. When filling the cavity in a wall, the main risk is likely to be rain penetration. BR 262 Thermal insulation: avoiding risks, gives useful guidance on minimising or avoiding risks due to the provision of thermal insulation.
