Trisobuild HW/ FWH

Site assembled walling system with internal and external profiles.

The Trisobuild® systems can be tailored to meet project requirements including fire resistance and acoustic performance.

The Trisobuild® HW System is a horizontally run external wall system which allows the secondary steelwork to remain horizontal with the spacer and bar system spanning vertically between these rails.

The capability of the system has been tested to provide a range of performances. The wall system can achieve up to four hours fire integrity and one hour fire insulation.

Trisobuild® FW (fire wall) range system build-up:

• The resistance to fire insulation and integrity in minutes are: FW15H: 15/240, FW30H: 30/240, and FW60H: 60/240.

• For the FW15H system, a minimum 160 mm Knauf FactorClad insulation quilt should be used. For the FW30H and FW60H systems, a Rockwool quilt of nominal density 24 kg/m³ should be used. A minimum depth of 160 mm for the FW30H system and 200 mm for the FW60H system. Consult manufacturer for details.

• External profile, side lap stitching is optional but recommended at a maximum 500 mm centres for aesthetic reasons only.

• Minimum 140 mm high Instaloc® Plus spacer system for the FW15H and FW30H systems should be used and 180 mm for FW60H.

• Internal liner profile.

Supporting structures:

When sheeting rails heat up during a fire they cease to function as structural members. Therefore, to prevent the wall from moving downwards under its own self-weight either a support at the head or base of the wall is required.

All Tata Steel firewalls can be designed to be supported from eaves, beams/ stanchions or rafters and posts if situated on a gable end. However, these elements must be protected using conventional fire protection materials to give the same period of fire resistance as the firewall.

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.

• Trisobuild® horizontal wall systems have been third party assessed using BS 476–22 ‘Fire resistance of non-load bearing elements’.

• 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:

Suitable for horizontal design walling applications.
