GRP Doorset U-Values
The U-values of GRP doorsets are very similar as the main insulation value comes from the core details (Polyurethene Foam).
PVC framed doorsets are compliant with Building regulations Part L and would have the following values when supplied unlgazed or with half glazed configurations.
|
|
|
| |
|
6 Panel door with PVC frame
1.2 W/m² K
|
|
Half glazed door with PVC frame
1.8 W/m² K (Standard glazing)
|
|
Half glazed door with PVC frame
1.5 W/m² K (Low E glazing)
|
| The configuration on the GRP leaf is panelled and flush. When considering other glazing options the U-Values will reduce proportionately with the reduction in glass area. |
