Many old houses have a small open or semi enclosed front or back porch that is completely unusable for most of the year, because it is drafty, uninsulated, and exposed to the weather. By installing EPS Cement Sandwich Panel to enclose the open sides of the old porch, you can turn this previously wasted space into a fully weatherproof, insulated sunroom, small dining area, or extra home office space. The panels add full thermal insulation that keeps the new enclosed space warm in winter and cool in summer, and they create a fully airtight seal that stops all cold drafts and rain water from getting inside. The smooth exterior and interior cement faces of the panel mean you can finish both sides of the new wall with paint or render, to match the existing exterior and interior style of your old house perfectly. This simple renovation adds a whole new extra usable room to your old house, at a tiny fraction of the cost of building a full new home extension.
