However, efficient thermal insulation must always go hand in hand with effective ventilation to prevent the build up of condensation
How Insulation Works
Heat flows from warm areas to cool areas, and moves in any direction. In the home, warm air expands and circulates, escaping through walls, ceilings,roofs, windows, doors, fireplaces, and anywhere plumbing, ducting or electrical wiring penetrates exterior walls. Thermal insulation acts as a barrier, reducing the amount of heat that escapes.
The term "U" value is used when discussing thermal requirements in a house, especially in conjunction with insulation products. The aim is to achieve low U-values: this means that a house's insulation is efficient. In a new-build home U-values are governed by building regulations, and the type of insulation used will therefore need to meet certain requirements.
A Method of Insulating a Solid Brick Wall
By first fixing wooden battens then inserting the celotex TB3000 (multi-purpose insulation boards) into the space between the battens. Screw plasterboard over the top of the battens, then skim the wall to create a finished surface. This process is shown below in one of our recent projects:
