Homes constructed prior to the year 1920 typically feature solid external walls devoid of a cavity, a characteristic that permits a substantial amount of heat to dissipate from the interior of your dwelling through the walls.
The implementation of External Wall Insulation (EWI) signifies a paramount improvement measure to your residence that significantly curtails heat loss. This insulation is strategically applied to the external face of the wall, serving as an effective barrier against heat transfer and thereby retaining a larger proportion of heat within your dwelling for extended durations.Ascertaining the type of wall your home possesses can generally be achieved through an examination of the brickwork on your home's exterior.
Solid wall construction is identifiable through the visible pattern displaying the long and short sides of bricks, akin to the illustration represented in Figure A.Conversely, homes featuring cavity walls exhibit brickwork where only the lengthier side of bricks is visible, as depicted in Figure B.
EWI is largely compatible with a wide array of property types, including those of non-traditional construction, with notable exceptions for listed buildings or properties situated within a conservation area. If these conditions pertain to your residence, it might be advisable to explore Internal Wall Insulation as a potential alternative.
Generally, the necessity for planning permission may be circumvented if the resultant aesthetic of the EWI closely matches that of the existing property exterior. However, definitive confirmation regarding this matter can be obtained from your local planning department.
