150mm Rigid Insulation Board 1200×2400

150mm Rigid Insulation Board for Roofing & Condensation Control

The 150mm rigid insulation board is the highest-performance option in the rigid board range,
intended for roofing projects where maximum thermal improvement is required.
Supplied in 1200mm × 2400mm sheets and sold per sheet, it is commonly specified for
warm roof constructions, major refurbishments and deep retrofit upgrades.

At 150mm thickness, this rigid insulation board delivers a substantial reduction in heat loss,
helping to maintain consistently warmer internal surfaces within the roof build-up.
By significantly reducing temperature gradients, it can play a key role in lowering the risk of
interstitial condensation when installed as part of a properly designed roofing system.

150mm boards are typically used where performance targets are demanding or where long-term energy efficiency
is a priority. Despite the increased depth, the boards can still be cut accurately on site and detailed
around roof penetrations, parapets and junctions with care and correct sequencing.

As with all insulation products, thickness alone does not guarantee performance.
Airtightness, vapour control and ventilation strategy must be considered alongside insulation choice
to achieve durable, condensation-resistant roof assemblies.
