Your installer will need to make sure that the insulation work you want done complies with current Building Regulations, and hopefully, he or she can obtain approval from the local Building Control Office on your behalf. Get the facts about Depend Exteriors.
Is there something I need to do to prepare my home for exterior wall insulation? Before beginning work on your insulation, your contractor must make sure that any recessed areas around your windows are properly insulated, with the depth of insulation needed based on the width of your window frames. All exterior pipework must be removed and replaced, and your windowsills and roof overhang must need to be extended to ensure that they protrude beyond your newly insulated walls.
Your exterior wall insulation will provide a weatherproof layer to your house, protecting it from damp for many years. Condensation would be less of an issue as the insulation raises the temperature of the surfaces of the internal walls.
If you still have damp issues in your house, you’ll need to fix them before installing exterior wall insulation. If you don’t, you risk trapping damp within your walls. It’s also crucial to make sure your new insulation doesn’t mask your walls’ damp-proof coating. To avoid rising damp issues, your insulation should begin above this layer. Your exterior surface would be fully weatherproof if an authorised contractor instals a recognised exterior wall insulation system.
Choose an exterior wall insulation installer who has been approved by the Insulated Render and Cladding Association (INCA) or the National Insulation Association (NIA) for the best performance. You can also check to see whether your installer uses Energy Saving Trust Recommended materials, as these materials will meet all applicable British Standards.
