Styrofoam Insulation Concrete Walls

Now as you glue the panels to the exposed concrete blocks leave a inch gap at the floor and ceiling and cut holes in the panels to fit around outlets and wall switches.

Styrofoam insulation concrete walls.

For a basement remodeling project consider insulating basement walls with foam board. There is almost no mess and the foam isn t itchy like fiberglass. Use a premade kit for this type of project. Additional r value for a masonry wall constructed using these materials needs to add the insulating value of additional wall components typically included such as 1 solid foam polyisocyanurate r 8 extruded polystyrene r 5 expanded polystyrene r 4 or 1 of perlite r 2 7 and for an exterior air film winter no wind r 0 17 an interior.

Insect and water problems if polystyrene forms are used for icf construction that exterior foam insulation may actually provide a route for insects and groundwater to enter the walls. Icf walls consist of several inches of rigid foam insulation and reinforced concrete which means they take up more space than traditional wood frame walls. Attach the tongue and groove insulation boards to the concrete wall with adhesive. Insulating concrete form or insulated concrete form icf is a system of formwork for reinforced concrete usually made with a rigid thermal insulation that stays in place as a permanent interior and exterior substrate for walls floors and roofs.

It comes in standard size 4 8 sheets and smaller sizes in many different thicknesses from 1 4 inch to 2 inches. Follow with a 2x4 frame wall and insulate it with batt insulation. Of concrete core and 2 125 in. Of eps on each side.

After the adhesive cures add extension boxes to the outlets and switches and spray foam into every gap top bottom and around each box. They are a lightweight polystyrene eps stay in place concrete form that speeds construction and yields a highly insulated wall. The forms are interlocking modular units that are dry stacked without mortar and filled with concrete the units lock together somewhat like lego. Homes constructed with insulated concrete forms commonly called icf in the trade offer some important advantages over traditional wood frame structures.

Some types of thicker foam board insulation are available but they may need to be special ordered. Foam board insulation is easy to use and is a great diy way to add some insulation. Polystyrene foam boards commonly called foamboard are a clean lightweight convenient way to insulate bare concrete walls.
