Render systems for solid & non-standard walls
External wall insulation wraps the outside of the house instead of eating the inside of it. For solid-brick, no-fines and non-traditional walls it is the highest-performing option there is, and nobody has to move out while it happens.
Insulation boards are mechanically fixed and bonded to the existing wall, then reinforced, basecoated and finished in a through-coloured render or a brick-slip finish. Because the insulation sits outside the structure, the wall itself stays warm, which removes the cold surfaces that cause condensation and gives the house a thermal store rather than a heat leak. You lose no internal floor area at all.
The work is in the detailing: window and door reveals, sills extended, eaves and verges built out, gas and electrical penetrations, drainage and downpipes reset, and a proper base detail above ground level. Done well it also transforms how the house looks. We survey, tell you whether EWI or internal insulation is the right route for your property, and quote a fixed price with a guaranteed system.
