About Our Cavity Insulation

Cavity insulation is a core part of modern wall construction, designed to limit heat loss through external walls while supporting compliance with current building regulations. Installed between the inner and outer leaf of masonry walls, cavity insulation improves thermal efficiency without affecting the internal space. It is widely used on new builds, extensions, and larger refurbishments across Oldham and Salford, where consistent wall performance and predictable installation are required.

Our Range of Cavity Insulation

Our cavity insulation range supports a wide range of wall build-ups, from standard residential construction to deeper cavity designs used on higher-performance builds. Cavity wall insulation is available in different thicknesses to suit varying cavity widths, helping builders achieve the required thermal performance without altering structural layouts.

Cavity wall insulation is commonly supplied in rigid or semi-rigid formats that fit neatly between wall ties, maintaining clear cavities and consistent coverage as walls are built up. These materials are designed to retain shape during installation, helping prevent gaps and thermal bridging once the wall is complete.

For projects with wider cavities or increased thermal targets, 150mm cavity wall insulation is often specified. This thickness is typically used on energy-efficient housing and developments where enhanced insulation values are required as standard. Deeper insulation options allow designers and builders to meet performance targets while retaining familiar masonry construction methods.

Cavity insulation is frequently coordinated with other elements of the building envelope, including lintels, wall ties, and internal linings. Many customers also source additional materials from the wider insulation category to ensure continuity of performance across walls, floors, and roof spaces.

Order Cavity Insulation Online

Cavity insulation can be ordered online and timed to align with your build programme, whether materials are required at the early blockwork stage or later during phased construction. Practical information on site access, collection, and drop-off options is available via our delivery and collection page. If you need confirmation on cavity depth or compatibility with your wall build-up, feel free to contact us before installation begins.
