Trisobuild wall facade steel profiles

All our products are fully tested by third parties for criteria such as thermal performance, fire safety, acoustic performance, air-tightness, and resistance to water penetration. This together with our extensive and unbiased technical support sets us apart.

All Trisobuild® roof systems can be covered under our Platinum® Plus system guarantee. Simply fill in your project details using our easy-to-use online specification tool or contact us directly.

All Trisobuild® components are easily handled on site without specialist mechanical equipment, due to lightweight components. This can be important when working on sites with limited access.

Loss Prevention Certification Board (LPCB) approval to LPS 1181 part 1 for fire performance, helps to lower insurance premiums.

All Trisobuild® roof systems when finished in Colorcoat HPS200 Ultra® or Colorcoat Prisma® will achieve a BROOF(t4) in accordance with EN 1187 and satisfy Building Regulations in relation to fire.

An Environmental Product Declaration (EPD) is available for all the Trisobuild® roof system solutions. Request a bespoke product or system specific EN 15804 Type III EPD to help accrue points under building certification schemes such as LEED and BREEAM.
