Metacaulk
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.

Metacaulk On Site Testing
In 1995, an on-site fire test laboratory was built for the purpose of conducting UL witnessed burns for through-penetration and construction joint assemblies. Our laboratory has been designated by UL under their Witness Test Data Program for fire testing to UL 1479 & UL 2079.
A computerized control room monitors all phases of test burns as specified by ASTM E-814 (UL 1479) or ASTM E-1966 (UL 2079).
|
Two on-site test ovens allow for quicker response to customer needs for UL approved systems and speed the development of new systems.
|
After test burns, assemblies are immediately subjected to a hose stream test to complete the ASTM E-814 (UL 1479) or ASTM E-1966 (UL 2079) procedure.
