Insulating walls to achieve a 0.30 U-Value

When insulating a home, the walls are just as important as the loft or floors. Insulating walls to achieve a 0.30 U-Value is important if going through building regulations.

According to the Energy Saving Trust, significant costs can be saved by ensuring your walls are fully insulated, also insulating solid walls can ensure protection from damp and a reduction in draughts throughout the home.

What is a U-Value?

U-values measure how effective a material is an insulator. A U-value is a calculation of the heat loss (in watts) per square metre.

Do I have solid or cavity walls in my home?

The easiest way to tell usually is by the brickwork. Looking at the brickwork on the outside of the house, you can identify if your property has Cavity or Soild walls:

  • Cavity walls, are identified by the the bricks being laid length-ways continuously. (Please see image below)
  • If you have Solid walls, an alternating pattern will be visible within the brickwork. You will be able to see some of the smaller ends from the outside.

Requirements for Building Regulations

Local authority building regulations will have specific requirements on Solid Wall projects. Current building regulation requirements for Solid Walls is to surpass a 0.30w/m² (U-value).
