Postcode, service and a phone number is all we need.
Part of every quote
- Vapour-open, so moisture in solid walls can dry outwards
- Finished in mineral or silicone render, or brick slip
- Heavier than EPS, so more fixings and careful handling
- Non-combustible board (typically Euroclass A1 or A2-s1,d0 as part of the system)

Before we quote in Sandhurst
We cover Sandhurst and nearby Crowthorne, Yateley and Camberley. Sandhurst is about 11 miles from Reading. Homes across the South East range from inter-war semis and post-war estates, which are mostly cavity-walled, to older solid-walled cottages and Victorian town terraces.
Much of Berkshire 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.
On blocks and taller buildings in Sandhurst, mineral wool is the default because of the fire guidance for external walls.

England: planning and regulations
For a house in Sandhurst, external insulation or render is often permitted development if it looks similar to the existing walls; conservation areas, flats, commercial buildings and listed buildings need permission or consent, so we check your address first.
Building control applies once more than half of a wall is insulated or re-rendered, or more than a quarter of the whole building envelope, and your written quote says how that's handled.
On residential buildings with a storey 11 metres or more above ground, guidance points to non-combustible external wall materials, and combustible materials are banned in relevant buildings 18 metres and over, so we specify mineral wool systems there.
What about noise?
Dense mineral wool adds mass and absorbs sound, so homes beside main roads or railways often notice a quieter interior, particularly where windows are also upgraded. The improvement depends on the whole wall and windows, so we don't quote decibel figures without testing.

Mineral wool EWI in Sandhurst: questions
Can mineral wool EWI have a brick finish?
Yes. Brick slips can be bonded over mineral wool systems designed for them, with additional fixings for the extra weight.
Is mineral wool needed for a bungalow?
Rarely for fire reasons. It may still be chosen on a damp-prone solid wall where a vapour-open build-up is wanted.
Does mineral wool get wet?
It is water-repellent and protected by the render system. Like any insulation it must not be left exposed to rain during installation, so boards are covered and work stops in wet weather.
