Thermal insulation in construction units is a major and crucial arena that need to be worked out only with the best insulation systems. Insulation4less.co.uk is the best store for all your insulation needs.

The Quinntherm Roof Insulation Sheets help in maintaining the optimum temperature inside the building. The insulations are provided with PIR (polyisocyanurate) which is suitable for imparting proper insulation to the floors that will be presented above the concrete slab. The sheets are firmly bonded on both the sides to merge the gas filled cells of the insulation with its metalized facings. This ensures that it offers an impressive strength and an increased thermal performance.

The Quinntherm Roof Insulation Sheets are light-weight and easy to install. They do not absorb water easily which makes them suitable for use in damp regions.

The insulation sheets in this range have a zero ODP (Ozone Depletion Potential) and are equipped with Polyisocyanurate (PIR) insulation which make is a completely energy efficient device. The eco-friendly approach of the insulation also assures that it is keeps the environment completely safe. It also readily decreases the CO² emissions with the improved thermal performance of the building,
