- Vapour-open and hygroscopic — buffers moisture rather than trapping it
- Made from a renewable material with low embodied carbon
- Often the most suitable EWI where planning allows on older properties
- Compatible with lime renders used on traditional buildings
Chiswick: walls, weather and approvals
Surveys in Chiswick also cover the surrounding W4 district and towns such as Acton and Barnes. London's housing includes a large stock of Victorian and Edwardian solid-wall terraces, inter-war semis and post-war blocks, and conservation areas cover many streets — so planning is often the first question for external work.
Much of Greater London 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 Chiswick, the survey looks closely at existing lime mortars and any cement patching that may trap moisture.

England: planning and regulations
Before quoting in Chiswick, 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 Chiswick: questions
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.
Can wood fibre go on a stone wall?
Yes, after levelling. Rubble stone is often uneven, so a levelling coat or adapted fixing method is used first.
Does wood fibre need a lime render?
It needs the render specified by the system manufacturer, which is usually lime or mineral based.
Do you cover Chiswick?
Yes — we survey and quote wood fibre external wall insulation in Chiswick (W4) and nearby Acton, Barnes and Shepherds Bush, with a fixed written price before any work starts.
