Floor Insulation Requirements
When you install insulation for your floor, you need to ensure it reaches the minimum energy efficiency ratings. These specific values are outlined in the official Approved Documents.Should it prove technically or practically impossible for you to achieve these exact standards, you must still upgrade the insulation to the highest level that is realistically attainable. Crucially, this improvement should offer a straightforward financial return, recovering its cost through energy savings within a maximum of 15 years.Furthermore, if your renovation project involves more than 25 per cent of a solid or suspended floor – particularly if you're replacing the screed or the timber floor deck – the work you undertake must adhere to the standards set out in the Building Regulations Approved Documents.
