WebNov 28, 2024 · A 225mm solid brick wall will have a U value of around 1.20W/m². A 450mm stone wall will be virtually the same, and a brick cavity wall about 1.50W/m². The requirement under Building Regulations is to reduce that to no more than 0.30W/m². A 50mm injected foam cavity-fill plus 20mm PUR external gives 0.28W/m². WebSep 22, 2024 · Spray foam insulation, especially the closed-cell kind, has an R-value of 6.0 per inch, sometimes as high as 6.5. Compare that to fiberglass insulation, including loose-fill, blankets, or batts. Although popular for insulating unfinished ceilings, walls, and floors, the R-value of fiberglass is between 3.1 and 4.3 per inch.

However, its main insulating material of polystyrene is flammable and can deteriorate over time with exposure to sunlight. EPS is very similar to XPS but has a lower R-value due to surrounding voids, or missing insulation.
