Many older houses have large heavy masonry chimneys that are no longer in use after homeowners switched to modern central heating systems, and these old chimneys take up huge amounts of valuable interior space while adding massive unnecessary weight to the home’s old foundation. When you demolish the old heavy chimney structure, you can use EPS Cement Sandwich Panel to build clean, finished new walls that seal up the old leftover opening in the floor, ceiling, and roof line. The total weight of these new panel walls is less than 5% of the weight of the old masonry chimney you just removed, which actually reduces the total dead load on your old home’s foundation, instead of adding extra stress to it. The panels can be custom cut to perfectly fit all the odd irregular leftover gaps around the old chimney chase, creating a smooth seamless wall surface that you can finish directly with paint or tile. This renovation instantly recovers several square meters of wasted space inside your old house, turning a previously unusable chimney cavity into extra storage space, a built in cabinet nook, or even a small new closet. This is one of the most high return old house renovation projects you can do, and EPS Cement Sandwich Panel makes the whole process far simpler and safer than traditional wall building methods.
