Warm Pitched Roof - Roof Space: Unventilated and Sealed
Eliminating traditional ventilation and the potential condensation risk associated with large voids of cool air make this the optimum pitched roof solution. With the potential of additional living space, a cathedral roof design or a conditioned roof void are rapidly becoming the preferred choice of pitched roof construction in the UK.

Warm Pitched Roof - Roof Space: Ventilated and Sealed
A sealed warm roof construction can also be achieved by creating a 50mm ventilated air gap between the surface of the insulation and the undertile lining to allow water vapour to be safely removed from the roof construction

Cold Pitched Roof - Roof Space: Ventilated
This traditional roof construction uses movement of air through the roof void to prevent the occurrence of harmful condensation. |
 |
Cold Pitched Roof - Roof Space: Unventilated and Sealed
The sealed cold roof system does not need the provision of ventilation directly into the loft space and works on the principle of a Monarperm vapour open or permeable underlay being used under the roof tiles simply allowing vapour drive to diffuse any water vapour harmlessly into the batten space and the external atmosphere beyond.
