External Wall Insulation in
Speedwell

Speedwell's 1930s semis are solid 9-inch brick with no cavity. EWI with 90mm graphite EPS brings the U-value below 0.30 W/m²K. We install over the existing render (if bonded) or after full strip-back if the substrate's compromised.

If your Bristol home was built before 1990, chances are it has no cavity wall insulation and minimal loft insulation. The result: heat loss through the walls (up to 35% of your total heat loss), cold spots around window reveals, condensation on inside walls, and high energy bills. External Wall Insulation fixes all of this in one go. We fix 80-150mm of high-performance insulation board to the outside of your property, then apply a reinforced base coat and a silicone or monocouche render finish. The result: a 25-35% reduction in heating bills, elimination of condensation, and a fresh modern exterior. EWI typically pays for itself in 8-12 years through energy savings. We install Weber, K Rend and Johnstone's EWI systems.

Speedwell is one of the more affordable east Bristol suburbs, sitting between Fishponds and the M32. The housing stock is dominated by 1930s semis on the older streets and post-war estate homes on the streets built in the 1950s-70s. Many of the older renders here are now failing and the homes benefit hugely from a through-colour monocouche or silicone re-render — instant kerb-appeal uplift without the maintenance burden of paint. We render more Speedwell properties per year than you'd expect, given the size of the suburb.
