Preformed Fiberglass Fittings

HAMFAB TYPE 1000° - Preformed Fittings


HAMFAB fitting insulators are unique and better because they’re molded, not mitered and glued together from flat stock board. Molding means that the HAMFAB product is manufactured utilizing the same type of process employed in the production of the straightrun insulation; and that ensures that our fitting insulator is going to match the rest of the system in thickness, density, thermal and acoustical efficiency.
