Professional cavity wall insulation across Yorkshire using Superbead 33, a high-performance EPS bead system designed for long-lasting thermal performance.
At Yorkshire Insulation, we install cavity wall insulation for homeowners across the region - filling the gap between your inner and outer walls to significantly reduce heat loss. Whether your walls have never been insulated or your existing fill has sagged and needs extracting, we'll check what's needed and get it sorted properly.
We use Superbead 33 - a high-performance cavity wall insulation system made from carbon-enhanced expanded polystyrene (EPS) beads bonded with adhesive. It offers excellent thermal performance, resists moisture, and is designed to last the lifetime of the building.
We work to current building regulations and use only approved materials - so the job is done right first time.
Cavity wall insulation starts from £23 per sqm depending on cavity depth - full pricing and assessment details are available on our pricing page.

Assessment appointment - we check whether you have a suitable cavity, whether existing fill needs extracting, measure cavity depth, and measure the walls that require treatment - £100 + VAT, deducted from your final bill
