About Insulation

Insulation Fibreglass Rolls

We stock a great selection of insulation fibreglass rolls including Knauf Earthwool insulation fibreglass rolls. Earthwool is a flexible, lightweight, low density, non-combustible glass mineral wool roll with high tear strength, perfect for the domestic and commercial construction sector. We also offer Knauf OmniFit insulation fibreglass rolls which are multi-purpose, flexible and non-combustible insulation fibreglass rolls, specifically designed for installation by friction fitting.

Insulation Fibreglass Cavity

County Building Supplies stock a great range of glass mineral wool slab insulation fibreglass cavity products for a wide variety of applications, from cavity walls to naval warships! Knauf Earthwool glass mineral wool is rot-proof, odourless, non-hygroscopic, does not sustain vermin and will not encourage the growth of fungi, mould or bacteria. It is chemically neutral and does not contain impurities, making it a highly popular insulation fibreglass cavity product. 

For fire and acoustic protection we also offer Earthwool OmniFit Insulation Fibreglass Cavity Slab is a multi-purpose, flexible, non-combustible, glass mineral wool slab, engineered for additional robustness, and specifically designed for installation by friction fitting.

Insulation Foil

Insulation foil boards by Quinn Therm are our most popular insulation foil products. Available in a variety of thicknesses from 25mm to 100mm+, Quinn Therm insulation foil boards are available from all County Building Supplies depots. Insulation foil boards are used in cavity walls, roofing insulation and to insulate floors. Insulation foil boards are suitable for new build and refurbishment projects.

Quinn Therm

Quinn Therm consists of a core of PIR (polyisocyanurate) foam with bonded facings. The gas filled cells give Quinn Therm its high thermal performance and strength while the range of facings maximises performance in individual applications. Quinn Therm is supplied as rectangular boards with a range of edge profiles.

Quinn Therm has a thermal conductivity as low as 0.022W/mK, making it one of the most effective rigid board insulations available. The facings have a hemispherical emissivity (E η ) of 0.07 ± 0.02 (BBA test report no. 2270) which enhances the thermal resistance of any cavities adjacent to Quinn Therm boards.

The water vapour resistivity of the core insulation may be taken as 300MN.s.g -1 .m -1 and a resistance value of 4000MN.s.g -1 .m -1 for each foil facing. In some applications the insulation foil facings may be sealed at the joints on the warm side with metalised tape which will eliminate the requirement for an additional air and vapour control layer (AVCL).

Quinn Therm does not rot and does not support mould or fungus. Quinn Therm is chemically inert, and poses no threat to anyone using it. Quinn Therm has an ozone depletion potential (ODP) of zero. It has a low Global Warming Potential (GWP), certified to ISO 14001 - Environmental Management Systems.

All Quinn Therm products, with the exception of QRFR-GFR and QRFR- BFR, achieve A+ rating when compared to the BRE Green Guide. QRFR-GFR and QRFR-BFR achieve A rating. When tested to EN 1604 Quinn Therm achieves level DS(TH)4 to EN 13165. Quinn Therm will perform for the service life of the building.

Insulation Polystyrene

We stock a wide range of insulation polystyrene at County Building Supplies. Our insulation polystyrene range features products from 25mm thickness to 100mm thickness and all insulation polystyrene is supplied per 2400mm x 1200mm sheet.
