Kingspan Thermawall TW50 Cavity Wall Board 450mm x 1200mm - All Sizes

THE PRICE SHOWN IS THE PRICE PER PACK. THIS PRODUCT IS SOLD IN PACK QTYS ONLY.

Thermawall TW50 is a high performance, fibre free, rigid thermoset insulation core faced on both sides with a low emissivity composite foil facing which is used for insulation in partially filled cavity walls.

Partial fill cavity wall insulation using Kingspan TW50 insulation board allows you to provide a robust barrier to run penetration. The board features a PIR core which is bounded by low emissivity composite foil on both sides which offers high water vapour resistivity.

The insulation board, with its low thermal conductivity value and low affinity for moisture, offers the best insulation to the cavity walls. The board is fabricated using a blowing agent that features zero Ozone Depletion Potential(ODP) and a low Global Warming potential (GWP)
