Trisobuild® RWL/ R

Trisobuild® R Roof System

Site assembled roofing system with internal and external profiles which offer design flexibility, a choice of perforated liner for acoustic applications and a depth of 19–32 mm.

The Trisobuild® systems can be tailored to meet project requirements including thermal and acoustic performance. The system comprises of a Colorcoat® pre-finished steel trapezoidal liner profile, a Instaloc® Plus spacer system, an insulation layer and a Colorcoat® pre-finished steel external weathering profile.

The roof and walkable liner (R and RWL) systems are fully compliant with ACR non-fragility standards. The systems can be adapted to suit a wide range of U-value performances with proven air-tightness that meet and surpass all Building Regulation requirements.

Available with a walkable liner option and also a range of glass-reinforced plastic (GRP) in-plane rooflight options to provide natural diffused daylight into the building.

Features and benefits:

• Certified 'very good' to Building Research Establishment (BRE)'s responsible sourcing standard BES 6001.
• Available with Platinum® Plus - a system guarantee for up to 30 years, that covers the durability, structural and thermal performance of all system components. The guarantee is derived from a tailored specification to suit your building function and is fully transferable on change of ownership of the building.
• Loss Prevention Certification Board (LPCB) LPS 1181-1 approved 460a 14, 15, 19, 23 and 31.
• The insulation within the system has both zero ozone depletion potential (ODP) and low global warming potential (GWP). Both these factors support the achievement of a high Building Research Establishment Environmental Assessment Method (BREEAM) rating.
• All steel elements are recyclable, without any loss of quality. The insulation can be separated easily and if kept ‘clean’ can be recycled. An environmental product declaration (EPD) is available for all Trisobuild® systems.

Thermal performance:

All quoted system U-values and construction ‘psi’ and f values have been computer modelled in accordance with EN ISO 10211 as stated in the Metal Cladding and Roofing Manufacturers Association (MCRMA) Technical Note 14 by trained and experienced technical engineers.

U-Values are based on secondary steelwork support at 1.8 m centres, 1.2 m bracket spacing and insulation with a 0.040 W/mK thermal conductivity.

Water penetration:

All roof systems are capable of being laid at a 4° roof pitch (with the exception of the 13.5/3 profile which is limited to 10°) following guidelines provided by the MCRMA technical paper 15.
