 Recommended R-Values For BC And Greater Vancouver
| R-Values | Location | Notes |
| 40 | Attic Roof | Any uninsulated attic/roof assembly |
| 20 | Wall | Any uninsulated exterior wall cavity. |
| 28 | Floor | Over unheated, uninsulated space |
Most building supply outlets do not have fiberglass blanket or batting solution available with R-Values higher than R38, which is inadequate for attic insulation in the Vancouver area. Affordable Quality Roofing always uses materials and processes that ensure your attic, roof, floors and walls are insulated beyond established R-Value ratings.
