Ravago Ravatherm XPS X 300 SL
Ravatherm XPS X 300 SL is a high-performance, multi-purpose polystyrene for the thermal insulation and frost protection of inverted flat roofs, green and blue roofs.
Ravago Ravatherm XPS X 500 SL
Ravatherm XPS X 500 SL thermal insulation with its closed cell structure is a perfect solution for the thermal insulation of heavy-duty inverted roofs, floor structures and load-bearing base slabs. It offers high strength with little compressive deformation and excellent thermal insulation properties even in damp environments over the long term.
Ravago Ravatherm XPS X 700 SL
Ravatherm XPS X 700 SL closed-cell polystyrene foam thermal insulation, with its excellent thermal insulation capability, high compressive strength and resistance to moisture, can be safely used in locations where good thermal insulation capability is only one of many complex requirements. It is suitable for load-bearing industrial floors, base slabs or high-load rooftop car parks.
Ravago Ravatherm SW A2 UPSTAND BOARD
The Ravatherm SW A2 Upstand Board, when combined with Ravago stonewool insulation and a 6mm fibre cement layer, offers a natural, non-combustible insulation solution for upstands in inverted roof finishes. Compliant with the latest building regulations, it meets the strict standards for materials used on external walls of buildings above 11m in height, achieving an impressive Euroclass A2 – s1, d0 rating according to Reaction to Fire EN 13501-1:2018.
Ravago Ravatherm XPS UB 300
Ravatherm XPS X UB300 pairs the exceptional thermal performance of Ravatherm XPS X 300 SB with a 6mm fibre cement layer, resulting in a specialist insulation board for use on parapets and upstands. It has been designed to address the challenge of thermal bridging in flat roofs and is an excellent choice for inverted roofs.
Ravago Ravatherm XPS X MK
Ravatherm XPS X MK is a water flow reducing layer (WFRL) used in conjunction with Ravaterm XPS X 300 SL. A WFRL is a critical component of an inverted flat roof, minimising heat loss due to the rainwater cooling effect. This product is a polyethylene geotextile.
