In a 100 sq ft wall, one cup of water can diffuse through drywall without a vapor barrier in a year, but 50 cups can enter through a ½ inch round hole. Sealing air leaks is 10-100 times as important as installing a vapor barrier.

Dry-sealed Once and for All

 
 

Formawall gives you a long service life and asks for little or no maintenance in return.

Formawall is installed with concealed horizontal butyl sealants and vertical dry gaskets that maintain a clean exterior appearance. Traditional wet seal joinery found in multi-component wall systems can dry out over time requiring costly re-caulking or repairs. Formawall?s vented, rainscreen, pressure equalized joinery minimizes the need for cleaning and maintenance.

Wet seals typically cure to a gummy texture that attracts dirt stirred by passing vehicles or wind. When it rains, dirt stuck in the joints runs down the wall, staining your building, seeping into porous brick and precast surfaces, removable only with costly, wasteful cleaning treatments.

With Formawall, the joinery sits within the wall – totally protected from the elements — producing a smooth, clean metal façade, impermeable to dirt and moisture. And the best part is, now the rain actually washes your building.
