Exterior wall insulation is the process of installing an insulation membrane to the
exterior walls of a building. A decorative finish is then applied such as a
coloured polymer render, acrylic render, pebbledash, brick, stone or timber cladding
systems. Exterior Wall Insulation will cut a 3 bed room semi-detached carbon footprint
by 2.1 tons per year saving upto £400 per year on heating costs, bringing older
properties up to the same insulation standard as modern day homes. Not only does
exterior wall insulation benefit the building thermally and aesthetically, it will
eliminate existing problems such as penetrating damp and internal condensation. This
makes exterior wall insulation an ideal renovation system, especially when a building
is in need of some repair work.
Exterior wall insulation is the ideal renovation system for single skin walls,
prefabricated concrete panels, solid wall construction and steel or timber framed
buildings. These types of structures can not be insulated with cavity wall insulation.
It is ideal for barn conversions and garage conversions as the insulation is installed
to the exterior of the building so it is not taking up valuable space inside the building.
There are several types of insulation material available such as phonelic board,
polystyrene sheets and eco-friendly options such as compacted mineral wool, and
wood fibreboards.
The insulation slabs varies in thickness from 20mm to 120mm, each have different
U values (unit of insulation). Each insulation slab has to be fixed and bonded
with careful consideration and skill, to ensure they are strong enough to withstand
the elements. Installing exterior wall insulation needs careful planning and preparation,
making sure all roof / eve over hangs are adequate, pipes, vents, extractors, window sills
can be extended, as well as wires and services can be accommodated.
