Ultimo HS is a multi-layer, robust membrane that is more than twice as strong
as standard breather membranes. This practical benefit ensures extremely high
nail tear and puncture resistance, whilst also helping to reduce the risk of falls on site.

Ultimo HS is an intelligent membrane that can deal with high levels of humidity and is able to absorb and release large amounts of moisture vapour in a measured, effective way. Therefore, the risks associated with condensation are virtually eliminated with Ultimo HS.

“Underlays which can hold or absorb moisture, and re-evaporate it when conditions are more favourable, are beneficial.”
