A Sleek Thermal Skin for Modern Envelopes
FOAMULAR 250 wraps a home in a crisp, uniform plane of blush-toned insulation that feels tailored and intentional. The 2-inch profile and tongue-and-groove edges create a tight, shadow-free surface that reads clean behind cladding. Pair it with warm wood siding or smooth stucco for a refined, energy-forward facade. It’s a quiet luxury—performance you can’t see, comfort you can feel.
