Both are significant.
Internal solid wall insulation systems.
Most modern homes are built with cavity walls which are made from two layers with a gap in between however many homes in the uk especially those built before 1920 were built with solid walls.
Saint gobain insulation uk manufacture and supply glass mineral wool slabs and slabs along with rigid polyisocyanurate pir boards that can be considered suitable for a wide range of applications across solid masonry walls masonry cavity walls timber framed walls steel framed walls rainscreen cladding walls and prefabricated walls.
Internal wall insulation our premium performance internal wall insulation products are suitable for use in a range of internal wall constructions.
Internal wall insulation typically consists of either dry lining in the form of flexible thermal linings available in 1 metre by 12 5 metre rolls laminated insulating plasterboard known as thermal board or built up systems using fibrous insulation such as mineral wool held in place using a studwork frame.
External wall insulation ewi as you might have guessed in ewi applications the insulation is fitted on the outside of the existing external walls typically as part of a cladding or render system.
A range of internal wall insulation systems suitable for solid properties what is solid wall insulation.
Ewi applications are a relatively straightforward means of insulating a solid walled property.
Internal solid wall insulation works by adding a thermal layer of material to the existing wall.
Solid wall insulation may be suitable for a variety of property types such as brick stone steel framed and concrete construction.
Internal wall insulation will tend to keep the wall at external ambient temperature and thereby draw the dew point towards the internal surface.
Solid walls can be insulated internally from the inside and externally from the outside.
If the dew point is too close to the internal surface of the existing wall moisture can be absorbed by the insulation and appear as damp patches on the plasterboard.
Rigid insulation boards are around 2 to 4 inches thick and made of plasterboard backed with insulation material usually foamed plastic.
Wetherby s new system utilises a high performance rigid phenolic insulation board bonded to a standard 12 5mm plasterboard available in a range of thicknesses to achieve the desired u value.
