The Roofshield Breathable Membrane is a highly water resistant roofing underlay that allows even very complex pitched roofs to breathe without the need for air gaps or secondary venting. Made with a unique, patented meltblown core that allows natural air movement to ‘supercharge’ the passage of moisture vapour from the roofspace, making the formation of condensation in the roofspace almost impossible.
