i-FAST External Wall Panel - Low Carbon, Fire Safe Timber Frame Panel

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

Available in two versions: i-FAST and psi-FAST.

Psi-FAST is an evolution of Innovaré Offsite’s award-winning patented i-FAST structural timber panelised system which uses increased panel thickness and staggered timber stud detailing to reduce U-values and psi-values whilst underpinned by rigorous fire testing to BS EN 1365-1 (loaded fire resistance testing) at the world’s only 5m fully loaded test facility in Dubai.

Manufactured offsite in a highly controlled environment i-FAST & psi-FAST solutions offer the capacity to include Pre-Manufactured Value (PMV) elements such as factory-fitted vapour control, windows and cladding.

Both versions can be specified without reliance on fire performance of ancillary cladding, membranes and linings.

Can be used within an Innovaré Offsite Full Structure or Wrap Building System.

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 benefits from rigorous BS EN 1365-1 (loaded fire resistance testing) at the world’s only 5m fully loaded test facility in Dubai.
• Evidence based fire resistance data underpins BS EN 1365-1 certification process and negates the need for 'Extended Field of Application’ (EXAP) by competent 3rd parties.

- Acoustics:

• RW 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:

• Inner layer of studs transfers vertical floor and roof loads.
• Outer layer of studs resist wind loads and support cladding.
• Racking stability provided by a double boarded panel.
• Durable high impact resistant facings with excellent fixing capacity.

- Thermal:

• Limited repeating thermal bridges from staggered stud.
• U-values from 0.23–0.11 W/m²·K depending on cladding and lining.
• Enhanced airtight performance from factory fitted VCL.

Consists of the following system components:

• RCM Multipurpose Board.
• Knauf Rocksilk.
• Solid Softwood Timber.
• Glue laminated softwood timber.
• Rothoblaas Traspir 250 breather membrane.
• Protect VC foil.
