Prefabricated external wall panel with intrinsic fire, acoustic, structural and thermal performance.

Innovaré Offsite’s award-winning, patented i-FAST structural timber panel system offers reduced U-values and psi-values underpinned by rigorous fire testing to BS EN 1365-1 (loaded fire resistance testing) to a height of 5m.

Manufactured offsite in a controlled environment i-FAST offers the capacity to include pre-manufactured value (PMV) elements such as factory-fitted vapour control, windows and cladding.

The panel can be specified independently of without reliance on fire performance of ancillary cladding, membranes and linings.

Can be used as part of a full structure, infill or wrap building structural strategy.

Please consult manufacturer for details.

Features and benefits:

- Fire:

30, 60 or 90 minutes standalone load bearing fire resistance and integrity.
Fire resistance enhanced by the addition of gypsum linings.
Insulation and board are both A1 non-combustible, Class 0 spread of flame.
i-FAST is tested to EN 1365-1 (loaded fire resistance testing) to a vertical height of 5 m.

- Acoustics:

R_W 56 dB (Ctr-5) standalone acoustic performance based on acoustic modelling.
Uprated to 60–62 dB with additional gypsum lining on one or both sides.
Used as an external wall behind brick cladding, the build-up will exceed 70 dB (Ctr -6).
Isolation of opposing boards gives resistance to airborne and impact sound.

- Structure:

Staggered studs or trussed stud arrangement.
Racking stability provided by a double boarded panel.
Durable high impact resistant facings with excellent fixing capacity.

- Thermal:

Limited repeating thermal bridges from timber studs.
U-values from 0.18–0.11 W/m²K depending on thickness, cladding and lining.
Airtight performance from factory fitted VCL.

Consists of the following system components:

RCM Multipurpose Cement Fibre Board.
