Trisobuild® SA

Site assembled acoustic system with internal and external profiles which offer a choice of perforated liner for acoustic applications.

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

The sound absorption (SA) systems are suitable for roof and wall applications, which can be specified to meet the required acoustic performance standards for any project.

Bespoke options are available for sound reduction, sound absorption or rain noise reduction. Consult the manufacturer for further details.

A stone wool slab of density 60 kg/m² is used above the liner with a vapour control layer (VCL) laid above this, spaced by a steel galvanized top hat stool that supports the spacer system, which in turn supports the external profile and allows standard glass fibre quilt insulation to be added to fulfil the required U-value performance.

Please note that the tested systems have all used a minimal 100 mm layer of quilt, however increasing this to meet lower insulation values will not reduce the absorption figures. Consult manufacturer for details.

The system build-up includes:

- Trisobuild SA1 and SA2:

• R32 0.7 mm Colorcoat® pre-finished steel external weathering profile.

• 100 mm glass fibre quilt, nominal density of nominally 12.5 kg/m³, 0.040 W/mK.

• 100 mm high Instaloc® approved spacer system.

• 1.6 mm top hat stub, size (l x h): 60 x 85 mm.

• 50 mm RW3 rock fibre slab from Rockwool, tissue faced to internal side, nominal density 60 kg/m³, λ = 0.039 W/mK.

• RL32 0.7 mm trough, trough perforated (SA1) or fully perforated (SA2).

- Trisobuild SA1+ and SA2+:

As above with the addition of the lining panel fitted with rock fibre infill pieces (tissue faced to internal side). 1200 mm long. Nominal density: 45 kg/m³, 0.0035 W/mK.

Features and benefits:

• Certified 'very good' to Building Research Establishment (BRE)'s responsible sourcing standard BES 6001.

• Platinum® Plus is a system guarantee for up to 30 years, derived from a tailored specification to suit project requirements.

• 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.

Applications:

Site assembled roofing and cladding systems.
