What are your options in insulating brick walls in your new build? Speak to your masonry contractor about two easy and effective options with foam insulation blocks and sheets. If you have a concrete block as well as the brick, you can first insert EPS insulation blocks within the cavities of the concrete blocks. This alone can increase the insulation within the wall by up to twelve times. In addition EPS insulation sheets can fit between the concrete and the brick layers to give you additional comfort levels. Ask your contractor and our knowledgeable team at Universal Foam Products for advice today.
