Solid Wall Insulation.

Improving the thermal efficiency of solid-wall properties is an area which has massive potential for the future as this is an area where very little work has been done to date. However, more and more individuals are now starting to recognise the advantages of insulating such households and this is an area which is now seeing a real growth with many effective cost-effective solutions now available.

The benefits of solid wall insulation.

If you live in a home with solid walls, 45% of your heat is escaping through the walls which is costing you money. Insulating the walls will dramatically prevent heat loss in the winter (and also reduce heat gain in summer).

How does it work?

A solid wall can be insulated either internally or externally � either option will greatly increase comfort, while also reducing running costs and the associated environmental impact. Internal 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 system using fibrous insulation such as mineral wood held in place using a studwork frame. External Insulation systems comprise of an insulation layer fixed to the existing wall, such as a protective render or decorative cladding. Dry cladding offers a wide range of finish materials that can be used � Timber panels, Stone or Clay tiles, Brick Slips or Aluminium panels.

Which Material ?

Flexible Thermal Linings and almost all brands of thermal boarding provide extremely high thermal efficiencies in regard to thermal insulation. Therefore, it is possible to achieve a very high level of thermal performance using relatively small thicknesses of insulation (which can be a major asset for small dwellings).

A combination of both insulated studwork and thermal board (instead of just finishing off with ordinary plasterboard) can be used to increase the thermal performance and further reduce running costs. This method can be especially advantageous where the internal wall face is uneven, because time spent preparing the internal wall face is reduced. The combined method also helps reduce thermal bridging.

Most external renders consist of either thick sand/cement render applied over a wire mesh, or a thinner, lighter polymer cement render applied over a �GRP scrim�. A pebbledash render should need less maintenance than a painted render finish.

Flexible Thermal Linings.

Flexible thermal linings are insulation on a roll specifically for use in solid wall homes, mansard roofs and dormer ceilings. The lining is 10mm thick and supplied in rolls one metre wide, 12.5 metres long. The material is made from a natural product � latex - in an open and closed cellular construction and has a durable fibreglass face that can be decorated with emulsion, wallpaper or even tiled.

Internal Rigid Thermal Boards.

Thermal boarding is a composite board made of plasterboard with a backing of insulation. The insulation backing can be specified in a variety of thicknesses. Insulation in excess of 60mm will typically be required to achieve best practice performance. Thermal boards are fixed to the wall surface using continuous ribbons and dabs of adhesive, plus additional mechanical fixings.

External Insulation.

External insulation systems are made up of an insulation layer fixed to the existing wall (using a combination of mechanical fixings and adhesive, depending on the insulation material used) and a protective render or cladding finish.
