Veltitech 145 is a lighterweight, non-breather underlay which can be specified as a replacement for a vapour-permeable underlay where eaves and high level ventilation are already included. NHBC requirements updated in Jan 2011 state that a vapour-permeable underlay must have high level ventilation on New Build projects. This was because a vapour-permeable underlay alone does not completely remove the risk of condensation during the drying out period on new build houses.
Non-breather membranes are also used in Scotland where the roof structure normally includes rigid sarking onto which the underlay is laid.
