External wall insulation (EWI)

• can be applied without disruption to the household
• does not reduce the floor area of your home
• renews the appearance of outer walls
• improves weatherproofing and sound resistance.
• fills cracks and gaps in the brickwork, which will reduce draughts
• increases the life of your walls by protecting the brickwork
• reduces condensation on internal walls and can help prevent damp (but will not solve rising or penetration damp)
• is best installed at the same time as external refurbishment work to reduce the cost
• may need planning permission - check with your local council
• requires good access to the outer walls
• is not recommended if the outer walls are structurally unsound and cannot be repaired.
