Metacaulk Firestop

Worldwide Leader in Firestop Technology - Our family of UL approved Metacaulk® Firestopping Products is specifically designed to fill voids in construction joints and around penetrations in fire-rated walls or floors. Many have intumescent properties and expand when exposed to heat, forming a high-strength insulating char.

Metacaulk® products contain a combination of biocides that protect the product in both the cured and non-cured state against mold growth. Our intumescent firestop products comply with required environmental exposure testing of accelerated aging and high humidity, as per UL 1479 Fire Test of Through-Penetration Firestops. In the event of fire, Metacaulk® sealants will restrict the spread of flames, smoke, hot gases and water. Whatever your application, we provide the most cost effective products to fit your every need.


Typical areas of installations include HVAC service penetrations, cable bundles, pipes, construction or expansion joints, Top of wall joints, curtain walls, composite sheets for clean rooms etc. We are authorised installer in Singapore and Myanmar, Yangon.
