Wood fibre EWI · Essex
Wood fibre insulation for older homes in Rayleigh
From Rayleigh to South Benfleet, we price wood fibre external wall insulation after a measured survey — no guesswork, and no work starts until the price is agreed in writing. For older stone and early brick properties in Rayleigh, we look at a wood fibre and lime build-up first.
- Free survey in SS6 and nearby
- Guide price from £150 per m² + scaffold, 0% VAT
- Fixed written price before work starts

Part of every quote
- Compatible with lime renders used on traditional buildings
- Vapour-open and hygroscopic — buffers moisture rather than trapping it
- Often the most suitable EWI where planning allows on older properties
- Thicker than foam for the same U-value
Before we quote in Rayleigh
As well as Rayleigh itself, we quote in South Benfleet, Wickford and Pitsea. It's roughly 6 miles from Rayleigh to Southend-on-Sea, the largest town in Essex. The East of England has a mix of post-war estates, inter-war semis and older solid brick and flint cottages, with some system-built council homes on post-war estates.
Much of Essex sits in the lower wind-driven rain exposure bands, which keeps the choice of finishes wide — though hilltop, coastal and exposed gable walls can still need a tougher specification, so we check the actual site.
For period homes in Rayleigh, the survey looks closely at existing lime mortars and any cement patching that may trap moisture.

Approvals in England
Before quoting in Rayleigh, we check whether the property is in a conservation area, under an Article 4 direction or listed, because that decides whether changing the outside needs planning permission.
If the work covers more than half of a wall, or a quarter of the building's whole envelope, it counts as renovating a thermal element, with a target of about 0.30 W/m²K where feasible.
What finish goes over wood fibre?
A lime-based or mineral render designed for the system, applied over a reinforcing base coat. Lime finishes give the softer, slightly irregular texture that suits cottages and older terraces.

Wood fibre EWI in Rayleigh: questions
Does wood fibre need a lime render?
It needs the render specified by the system manufacturer, which is usually lime or mineral based.
Is wood fibre worth the extra cost?
On older solid walls the main benefit is moisture safety rather than raw U-value. If the wall needs to breathe, the cheaper option can cost more later.
Is wood fibre insulation fireproof?
No — it's a timber product. It chars rather than flaming readily, but it is combustible, so it's used on low-rise buildings within a tested system and never where non-combustible materials are required.
Do you cover Rayleigh?
Yes — we survey and quote wood fibre external wall insulation in Rayleigh (SS6) and nearby South Benfleet, Wickford and Pitsea, with a fixed written price before any work starts.
