Converting a dusty unused attic into a new usable bedroom, home office, or hobby room is one of the most popular old house renovation projects, but most old attic floors were not engineered to support the heavy weight of traditional wall construction materials. The EPS Cement Sandwich Panel is the perfect material for attic conversion walls, because it is extremely lightweight and adds almost no extra dead load to the old attic floor structure, so you usually do not need to do expensive structural floor reinforcement work. The built in thermal insulation of the panel also adds an extra layer of warmth to the attic space, helping to keep the converted room warm in winter and prevent it from getting uncomfortably hot in the summer. The panels can be easily cut to fit all the odd angled shapes and sloped ceiling lines that are very common in old attic spaces, creating clean neat wall lines that follow the unique geometry of the roof structure perfectly. Unlike heavy plasterboard that is very difficult to carry up narrow old attic staircases, the lightweight EPS Cement Sandwich Panel can be easily maneuvered up even the smallest attic access hatch. This makes the entire attic conversion project far faster, safer, and more affordable than using traditional wall building materials.
