Hot melt structural waterproofing system for inverted roofs on timber and concrete decks. Please see other Duoflex system listings for alternate deck and ballast options.
Application
Suitable for use in a ballasted blue roof system with an SBS modified bitumen protection membrane, XPS insulation and water flow reduction layer.
Description
Hot melt inverted blue roof system on concrete substrate. This system is designed for a Blue Roof application, using the Duoflex Hot Melt system with a cold applied high bond SBS bituminous primer, heavy duty reinforcement fleece, SBS modified bitumen with a polyester reinforcement, XPS insulation and a lightweight and easy to install waterproof and vapour permeable water dispersion geotextile layer loose laid over the XPS insulation.
Features include:
- Insulation has exceptional compressive strength and outstanding energy efficiency.
- The insulation is also 100% recyclable.
- Water Flow Reduction Layer contributes to the thermal performance of the roof by retaining the water so it does not penetrate the insulation to the waterproofing layer.
- Easy to install.
- BROOF(t4) rated.
