We bring clarity to the complexities of building science and code compliance. Our capabilities, insights, product and performance testing, and technical engineering support can help you design, build and manage smarter and sustainable products and buildings.
Product Description
Fire-rated doors, wall, floor and ceiling assemblies provide the necessary fire and smoke barriers to create compartmentalization during a fire, safeguarding against the spread of fire and smoke within a building or to and from a building. These assemblies need to meet fire and smoke safety and environmental sustainability requirements. We can help ensure that your materials, systems and assemblies are designed to meet these requirements by providing third-party certification of their safety and performance.
Our solutions also help confirm the safety, performance, reliability and security of your fire-resistant rated designs. Fire-resistance rated designs are used to achieve code compliant installations where the building codes require hourly rated designs. We test assemblies to international standards, establishing an hourly rating to provide evidence of compliance to code requirements.
