HYDROSHIELD®
Springvale Hydroshield for Inverted Roof Insulation, expanded polystyrene (EPS) boards for use as inverted roof insulation on new and existing domestic and non-domestic untrafficked flat and zero fall roofs, and terraces subject to pedestrian access only.
The insulation boards are used with the Hydroshield water-flow-reducing layer between the insulation and the ballast layer.
When used in conjunction with a suitable root barrier, the Springvale Hydroshield EPS 300E grade may also be used in green roof applications.
The products are supplied in 2 grades, EPS 200E and EPS 300E to meet a range of compressive strength requirements and have a reaction to Fire Classification of Class E.
Providing excellent thermal insulation properties, Hydroshield is manufactured in a range of thicknesses to allow the required U value to be achieved and can be used with other products from the Springvale range to aid compliance with Approved Document Part L of the building regulations.
Benefiting from the excellent environmental aspects of EPS Hydroshield is quick to install with little waste and is supplied based on your bespoke roof design and U value requirements.
