The most widely used EWI board. Moisture-resistant, lightweight, and cost-effective. Available in a wide range of thicknesses for flexible specification.

Premium closed-cell phenolic board delivering best-in-class U-values at minimal thickness. Ideal for EWI where wall build-up must be kept slim.

Non-combustible A1-rated boards for fire-critical projects. Naturally breathable and suited to solid masonry walls. Excellent acoustic performance.

Sustainably sourced wood fibre board with a breathable render finish. Handles moisture without degrading — ideal for older or solid-wall properties.

A purpose-engineered internal wall insulation system with an integrated air and vapour control layer. Designed specifically for UK housing stock.

High-performance rigid PIR boards that achieve excellent U-values in a slimmer profile than mineral wool alternatives — useful where internal space is at a premium.

All-in-one insulation and plasterboard for ceilings and dot-and-dab wall applications. Single-fix solution minimising on-site steps.

The tried-and-tested choice for loft floors. Easy to lay in multiple layers to hit current building regulation targets. Cost-effective at scale.

Rigid PIR boards for lofts where space is limited or a walkable surface is needed over existing insulation. Higher performance per mm than mineral wool.

Two-layer PIR system between and below rafters for a warm roof. Widely used for loft conversions where the rafter void becomes habitable space.

Flexible wood fibre batts that friction-fit between joists or rafters. Excellent acoustic properties and fully breathable — suited to heritage buildings.

The standard choice for warm flat roofs. Laid above the structural deck, below the waterproofing membrane. High thermal performance in a compact layer.

Non-combustible A1-rated option for flat roofs. Suitable where building regulations require fire-resistant insulation above or below the deck.

Durable, low-absorption EPS boards suitable for inverted flat roof systems (insulation above waterproofing). Highly resistant to freeze-thaw cycles.

Friction-fitted between suspended floor joists. Breathable and moisture-tolerant — important under timber floors where ventilation is key.

Used under timber or concrete floors for high-performance insulation with a slimmer build-up. Suited to both renovation and new-build floor refurbishment.

Ultra-thin phenolic board for solid floors where minimising floor level rise is critical. Best U-value performance per millimetre of any floor insulation.

Specifically engineered for acoustic floor performance — reduces impact sound transmission between floors. Used in flats, conversions, and party floor applications.

Wood fibre batts laid between floor joists for thermal and acoustic performance. Excellent for timber frame and heritage floor structures.
