Hi-Therm Lintel Psi 0.05 W/m·K
Hi-Therm LintelA hybrid of Glass Reinforced Plastic (GRP) & Galvanised Steel When combined, these two materials form the ultimate in lintel design. |
IG leads the way with the development of a completely unique lintel range to address the thermal requirements of new building regulations.
The benefits
- GRP has very low thermal conductivity and therefore when used to support the outer leaf in cavity wall construction, cold bridging is significantly reduced.
- Galvanised steel, which has a much higher load bearing capacity than GRP, is used to support the heavier load on the inner leaf of the cavity wall.
- DPC is not required with the Hi-Therm Lintel
Key Performance Features
- Outperforms all other lintels on Thermal Performance.
- Outperforms even stainless steel for corrosion resistance.
- Outperforms Stainless steel on price.
- DPC is not required with the Hi-Therm Lintel
Building regulations require that lintels should be assessed for their effect on the thermal performance of a building. Thermal performance of a lintel is expressed in terms of Psi Values (ψ) i.e. linear thermal transmittance.
The thermal performance of the Hi-Therm Lintel has been evaluated by the Building Research Establishment (BRE) and achieved a Psi value of 0.06 W/m·K.
Psi Comparison Chart
To help understand the immense thermal benefits of the GRP lintel it must be compared to other lintel types.
Testing of IG's Hi-Therm Lintel was carried out by the BRE (Building Research Establishment) using Physibel's thermal analysis software TRISCO which complies with BS EN ISO 10211-1. The modeling follows the requirements of the BRE conventions document BR497.
