First on the Block

Dealing with the inevitable moisture in a cavity wall becomes critical in retaining the thermal performance of the insulation for the life of the building.

That’s where Dow comes in. For more than 60 years, rigid foam insulation products from Dow have delivered proven performance in block-backed cavity wall construction, providing high thermal performance, moisture resistance and durability.

Installed on the exterior of block-backed walls, rigid foam insulation from Dow helps moderate the cavity temperature, reducing the potential for condensation. And the specially sized products fit between wall ties, helping save time, labor and materials.
