Product Features
- Lightweight 1190 x 450mm boards (installed dimensions)
- Tongue and groove edge profile
- Low emissivity foil facing
- BBA approved – certificate 16/5343 (Full Fill Cavity Walls)
Fire Classification
Euroclass F Reaction to Fire classification, according to BS EN 13501-1. Products with this level of classification are not provided with a rating for smoke emission.
Product Specification
Thickness (mm) | Length (mm) - Net/installed | Width (mm) - Net/installed | Lambda Value (W/m.K) | R-Value (m².K/W) |
---|---|---|---|---|
90 | 1190 | 450 | 0.021 | 4.25 |
115 | 1190 | 450 | 0.021 | 5.45 |
140 | 1190 | 450 | 0.021 | 6.65 |
Product Benefits
- Thermal Performance - Excellent thermal performance with a thermal conductivity of 0.021 W/m.K, reducing the thickness of insulation required to hit the target U-value.
- High Performance Facer - Low emissivity foil facing provides improved thermal performance in sealed cavity air spaces, improving the achievable U-value (based on a residual cavity of 10mm).
- Easy to Install - The boards are sized to fit standard cavity wall tie spacing. They are light and rigid, assisting with ease of transportation, handling and fitting.
- BBA Certified - Thermaclass Cavity Wall 21 has been assessed by the BBA as fit for use in defined full fill cavity wall applications if installed, used and maintained as set out in the certificate. Please read the BBA certification page for full details and restrictions.
