Insulating a wall externally has its fair share of benefits. Not only do you get the benefits of most of or all the work taking place outside your home, but you also get the benefit of not having to remove wall fixtures and fittings such as radiators and you won’t need to worry about the décor in the room being affected either. External wall insulation surrounds the property in a thermal envelope, allowing the mass of the internal walls to act as a thermal store, contributing to a more energy-efficient and thoroughly insulated household.
Installation involves fixing an insulating material to external walls, with a protective render and/or decorative cladding over the top, so it will improve your properties appearance and add value. The thickness of the insulation needs to be between 50-100mm.
Once your external insulation is fitted, decorative coatings and cladding can be used to give a look and finish of your choice. This can match a wide variety of homes, including Georgian, Victorian and Edwardian properties.
Yo may not be aware that solid walls let twice as much heat escape as cavity walls – so insulating them makes a good deal of sense.
If your home was built before 1920, it probably has solid external walls rather than cavity walls, which only came into widespread use in the 1920s.
For brick-built homes, you can also tell by checking the thickness of your external walls. Do this by measuring them in an external doorway or window. If a wall is less than 10 inches thick, it’s probably solid.
While cavity walls can be insulated quickly and cheaply, solid wall insulation is a more involved process, both will save you money on your heating bills but internal insulation is the most efficient.
