Thermaclass Cavity Wall 21 is an easy to install, high thermal performance polyisocyanurate (PIR) insulation board for full fill cavity wall applications, with a thermal conductivity of 0.021 W/m.K. It can be installed with up to a 10mm residual cavity (to support ease of installation and accommodate mortar squeeze) or as a full fill solution with no residual cavity.

The boards have a low emissivity foil facing to each side and feature an engineered tongue and groove joint profile, helping to ensure a continuous layer of insulation to maximise thermal performance and provide protection from wind driven rain.

Product Features

Lightweight 1190 x 450mm boards (installed dimensions)
Tongue and groove edge profile
Low emissivity foil facing
BBA approved – certificate 16/5343

Product Properties

Board size: 1190 x 450mm (installed) 1205 x 465mm (including tongue)
Thickness : 90-140mm
Material: PIR

Product Performance

Lambda: 0.021 W/m.K
Reaction to Fire: Euroclass E Reaction to Fire classification, according to EN 13501-1 (Products with this level of classification are not provided with a rating for smoke emission)

Product Benefits

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.
Low emissivity foil facing provides improved thermal performance in sealed cavity air spaces, improving the achievable U-value.
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.

Applications

External Walls – full fill cavity wall

Key Considerations

Thermaclass Cavity Wall 21 should not be used in the external walls of buildings over 18 metres in height (England and Wales) or 11 metres in height (Scotland). Recent changes to Building Regulations mean that only non-combustible insulation or insulation of limited combustibility can be used in buildings of that height.
