Many old houses have attached sunrooms or conservatories that were built decades ago with almost no insulation, single pane glass, and leaky walls, making them so hot in summer and freezing cold in winter that they are completely unusable for 8 months of the year. By installing EPS Cement Sandwich Panel on the interior walls of the old sunroom, you add a full continuous layer of thermal insulation that stabilizes the indoor temperature, turning the previously unusable space into a comfortable year round living area. The panel also creates a fully airtight seal that stops cold drafts and rain water leaks from penetrating through the old sunroom walls. The smooth panel surface is perfect for painting, tiling, or adding decorative wood trim, so you can match the new sunroom finish perfectly to the rest of your old house’s interior design. Unlike trying to insulate the old sunroom walls using traditional methods, which would require tearing out all the old interior finishes, the EPS Cement Sandwich Panel can be installed directly over the existing old wall surface with minimal demolition work. This renovation lets you recover a whole extra usable room in your old house, that you previously could not use for most of the year.
