80mm Cavity Wall Insulation

80mm Xtratherm Cavity Wall Insulation. Our PIR boards achieve high standards of insulation whilst maintaining a residual cavity to prevent moisture penetration, without a substantial increase in the width of the cavity. Cavitywall insulation is a great way to insulate your home. With ease of installation and very cost effective, this form of insulation is the most common way existing and new homes are being insulated today. You can fix these boards by using wall ties withing the cavity itself tied back to the inner and out leaf. All of which can be purchased within our online shop. Cavitywall insulation is generally used along with insulated plasterboards or warmboards but can also be used on its own. 

The Thermal Conductivity of our PIR Boards is 0.022 W/mK.
