Hi,
We are planning a KDR. We have 2 whirlybird (fairly new) on the current house and was wondering if would be of any advantage to keep them and get the builder to install them on the new house.
The new house will have sarking and insulation in he roof but was wondering if the whirlybirds would help getting rid of hot air trapped in the roof cavity and getting air movement to reduce the possibility of dampness.
Any comment greatly appreciated
Thanks
