Roof
Traditionally, New Zealand roofs were designed as "cold" areas with the insulation at the ceiling. By moving the insulation to above the rafters, we form a "warm roof" concept, similar to the more familiar flat roof approach.Â
This concept is especially useful for skillion roofs where there is no ceiling space.
Roofing Insulation Options
Similar to a wall build-up, the insulation is fixed over the structure (rafters in this case) and then counter battens or purlins are fixed through the insulation into those rafters.
Benefits
-
Can be used with all types and pitches of roofs to provide a continuous insulation layer.
-
Interior finish retained with no loss of volume.
-
Able to mitigate condensation and airflow.
-
Very low loading of the roof structure.
For best in class fire and acoustic performance, ROCKWOOL HardRock boards is unrivalled.
Benefits
-
High resistance to compression and point loading
-
Non-combustible and can withstand at least 1000ºC without melting
-
Boards do not shrink, warp or deform over time
-
Provides excellent sound absorbing properties
