Foam Board Insulation for Exterior Basement Walls

With InSoFast foam board insulation panels designed for application to exterior basement walls, your home can meet all present and future energy codes and more. Your home can be made more durable, comfortable, quiet, and affordable with a simple insulation project you can manage on your own.

The traditional wood frame paired with fiberglass insulation creates a gap in the coverage of insulation at every stud location. Thermal energy and moisture is able to cross through the wall effortlessly, reducing the R-value of the insulation significantly.

Foam Board Insulation for Exterior Basement Walls

InSoFast insulation panels provide continuous insulation coverage that lacks each of these problems: thermal bridging, moisture intrusion, and R-value reduction.

The thermal bridging that occurs due to the presence of a wooden frame is avoided with InSoFast insulation panels. The polypropylene studs within the panels are sheathed within the insulation to keep the insulation coverage from being broken. The panels also include tongue-and-groove notches that ensure true, straight alignment and an airtight fit.

Intrusion of moisture into homes results in rot, decay, mold, and mildew. Fiberglass insulation loses practically all of its thermal protection. InSoFast insulation panels’ R-values are constant. The panels aren’t porous, have moisture control channels, and do not break down over time or when exposed to moisture.

The R-value of many insulation products lessens over time. Fiberglass settles and covers less area and breaks down when exposed to moisture. InSoFast insulation panels do not diminish. They’re physically and chemically stable and do not release toxins.

Whether installing InSoFast insulation panels to the interior or exterior of a home, the project will be simple. The alignment notches keep the system true and straight without taping, and you can modify the panels to fit appropriately with a utility knife and a saw. For adhesion to the exterior, you can use either construction adhesive, masonry adhesive, or mechanical applications like nails or screws.

The InSoFast Flat Panel EXe 2.5

The Flat Panel EXe 2.5 provides R-10 continuous insulation and serves as a weather screen assembly. The panels are designed to suit outside purposes, moisture control, and thermal efficiency. Drainage channels on each side protect from moisture, and the non-porous panels tightly connected outperform fiberglass labeled as R-15.

The InSoFast PLUS system allows you to amp up the R-value even more by adding a layer of rigid foam board over your InSoFast system for a cumulative effect.

Installing our panels doesn’t require abatement of paint, removal of trim, or any demo to access the wall cavity. The panels can go straight onto the home’s wrap, and when complete, the system operates as a secondary weather resistant barrier. The panels’ embedded studs provide a place to install a range of 2” finishing materials.

The studs are strong enough to hold up to 250 pounds, with the same strength as 20-gauge steel studs. Multiple finishing materials can be used on the same home, and application of these products will not disturb the waterproofing underneath.
