Protect VP300 is a medium weight vapour permeable roof underlay with a vapour resistance better than that required by BS 5250 and a strength greater than many other underlays in its class. It is suitable for all pitched roofs particularly fully supported applications. Protect VP300 is both CE marked and BM TRADA certified and provides an economic solution when the highest specification of roof underlay such as VP400 PlusLR is not required. Protect VP300 can provide a secondary line of defence against wind driven rain and snow, the reduction in wind uplift loads on the roof covering and is also able to be used as a temporary roof covering before the slates or tiles are applied. Please note this product does not require the joints & laps to be taped but must be battened correctly. PropertiesLength: 50m. Width: 1m. Roll size: 50m2. Roll weight: 6.55kg. Weight: 125gsm.
