What's included
- Non-combustible board (typically Euroclass A1 or A2-s1,d0 as part of the system)
- Used on blocks of flats and buildings with storeys above 11m
- Heavier than EPS, so more fixings and careful handling
- Vapour-open, so moisture in solid walls can dry outwards

Local considerations in Crewe
As well as Crewe itself, we quote in Winsford, Kidsgrove and Congleton. Crewe is about 21 miles from Warrington. The North West has one of the largest stocks of pre-1919 solid-wall terraces in England, alongside Pennine stone houses and post-war estates.
Exposure to wind-driven rain varies across Cheshire: sheltered town streets fare better than walls on high ground or facing the prevailing weather, and the render, beads and cill details are chosen with that in mind.
On blocks and taller buildings in Crewe, mineral wool is the default because of the fire guidance for external walls.

Permissions in England
Planning in Crewe follows England's national rules: similar-looking finishes on houses are usually permitted, while flats, commercial premises, conservation areas and streets under an Article 4 direction need an application.
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.
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 Crewe: questions
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.
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.
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.
Do you cover Crewe?
Yes — we survey and quote mineral wool external wall insulation in Crewe (CW1) and nearby Winsford, Kidsgrove and Congleton, with a fixed written price before any work starts.
