To select a suitable foam board for a high standard building , many conditions need to be considered , where you live , which structure , what’s the thermal level, new or remodeling and even the personal preference...But base on our professional knowledge and experiences , we could offer some essential constructive suggestion such as thickness etc for you warm and great projects .
For thickness,A professional R-value(according to ASTM C518) date sheet could be a important design reference ,Thermal resistance (R–value) varies with thickness and is calculated by dividing the thickness of the board.
| Insulant thckness (mm) | Thermal Resistance (R-value) (m²K/W) |
|---|---|
| 20 (0.79 in) | 0.92 |
| 30 (1.18 in) | 1.38 |
| 40 (1.57 in) | 1.84 |
| 50 (1.97 in) | 2.30 |
| 60 (2.36 in) | 2.76 |
| 70 (2.76 in) | 3.22 |
| 75 (2.95 in) | 3.45 |
| 80 (3.15 in ) | 3.68 |
| 90 (3.54 in) | 4.14 |
| 100 (3.94 in) | 4.60 |
Also you can have a preliminary assessment before the detail calculation from the reference of below recommend sheet, check the building location and start your great beginning.

The R-Value calculation will be used to assess what level of thermal insulation is required to the Building Regulations for both new-builds and refurbishment projects.
The value will depend on a number of different factors including:
For a refurbishment building, select a same or higher thermal resistance performance SINSU Potherm® insulation to substitute the old products , the below technical sheet may give you some constructive and quick help.
