What is External Wall Insulation in Blackburn?
External wall insulation provides a weatherproof layer that will protect your brickwork, increase sound resistance and help to prevent damp problems.
A layer of insulated panels is fitted to the outside walls and covered with render or cladding. There are a variety of finishes to choose from including smooth, textured, tiled, painted or brick/stone effect.
The insulation panels are fitted to the external substrate of the property so it won’t reduce the floor area and can be installed with minimal disruption. It will also renew the appearance of your walls, increase the value of your property and will result in large savings on your heating bills.
