Formawall® is an insulated, secret-fix, flat architectural wall-cladding panel which is quick and easy to install for fast build times. Available in a range of sizes, shapes and colours and with extensive fabrication options, it offers design flexibility which enables architects to create unique and modern design solutions. Single, double and multi span configurations are available.

Features and benefits:

Flat panel profile.
Flexible design allows vertical and horizontal panel installation.
Panel lengths up to 12 m and core depths of 70, 90 and 120 mm optimize the speed of installation and minimize waste while providing U-values down to 0.17 W/m²K.
Lower air permeability of the system reduces energy costs, carbon emission rates and facilities compliance with Building Regulations Approved Document L2 (E&W) and Technical Handbook 6 (Scot).
A wide range of flashing, ancillaries, corner and curved panel options available.
Third-party validation of high standards of quality, thermal performance, fire safety, acoustic performance, air-tightness water penetration and environmental credentials.
Loss Prevention Certification Board (LPCB) approval to LPS 1181-1, helps reduce insurance premiums and assures reaction to fire performance.
Fire resistance performance of 15 minutes insulation and four hours integrity achievable. Internal panel joint stitching at 250 mm is required to achieve this performance, as well as limiting the panel span to 1.525 m.
Available with Platinum® Plus - a system guarantee of 25-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.
Colorcoat Prisma® pre-finished steel used as standard, offering a wide range of colours and long-term performance for up to 40 years with the Confidex® guarantee.
FM approved to Class 4880, 4881 and 4471 to unlimited wall height.
CE marked (performance in accordance with BS EN 14509).
Full traceability of all component materials and certified 'very good' to Building Research Establishment (BRE)'s responsible sourcing standard BES 6001, which helps increase credits under the Responsible Sourcing of Materials section of Building Research Establishment Environmental Assessment Method (BREEAM).
All steel elements are 100% recyclable, without any loss of quality.

Fire performance:

Formawall® carries Grade EXT-B and EXT-A approval by the LPCB. Also fire resistance performance of up to four hours integrity and 15 mins insulation. These are attained by stitching the liner face at 250mm centres.

The internal surface of the panel complies with a Class B s2 d0 rating in accordance with EN 13501-1.

Water penetration:

The Trimapanel® system's joint is water-tight up to a pressure of 1050 Pa, when tested to BS EN 12865 ‘Hygrothermal performance of building components and building elements’

Air-tightness:

In accordance with Building Regulations Approved Document L2 (E&W) and Scotland (Technical Handbook Section 6 Energy) tests to EN BS 12114 shows the sealed panel of air leakage as low as 0.48 m³/h/m² at an applied pressure of 50 Pa.

A practical expectation for a finished building, with effective sealing at all junctions, would be 5-10 m³/h/m². However, enhanced detailing practises on large shed buildings can realise air leakage performance figures of less than 3 m³/h/m².

Thermal performance:

The panel construction offers highly consistent insulation performance, and the site formed junctions provide a practical and effective method of ensuring good thermal performance.

U-values:

70 mm thickness: 0.31 W/m²K.
90 mm thickness: 0.24 W/m²K.
120 mm thickness: 0.17 W/m²K.

Acoustic performance/ Sound reduction (SRI) weighted values:

Based on a 70 mm core, weighted SRI Rw: 28.9 dB, consult technical literature for further details.
