Polystyrene formwork block 1440 WEB

for wallinsulating

The 4-inch cavity web (WEB04R) is made with injection-molded polypropylene for strength and performance. Webs contain built-in rebar clips to hold the rebar in position, reducing the need for ties. Cavity webs slide and lock into place to join two Formtech panels, which creates a form. Four-inch webs come packaged in minimum quantities of 300 per box.
