Strata – Reinforced Bituminous Membrane To Warm Roof – Torch Applied
Verified by manufacturer 2 days ago
Polymer modified bitumen membrane roofing system.
Application
Reinforced bituminous membrane roof waterproofing.
Description
A polymer-modified bitumen, torch-applied roof membrane system.
STRATAPRO M is a multi-layer composite bitumen waterproofing membranes. The underside of the membranes are made of SBS modified bitumen, while the upper layer is made of APP modified bitumen. The SBS on the lower face offers high level of flexibility, and boast elongation of up to 2000%, it will remain flexible in temperatures as low as –25°C, and has a high resistance to thermo-oxidative ageing. The upper layer consists of an elastoplastomeric mix of distilled bitumen, atactic and isotactic polypropylene and UV resistant polyolefin elastomers, supplemented with thermal shock stabilisers.
The membrane has a composite prefabricated three-layer reinforcement system. A fibreglass mat is compressed between two layers of nonwoven polyester fabric, this reinforcement limits the movements of the membrane both at high and low temperatures providing stability to the membranes.
Suitable for both torched application and mechanical fixing, the fibers within the membrane are impregnated and coated with an elastomeric mix using an exclusive procedure which guarantees absolute waterproofing, high resistance to tearing and impact, and excellent elasticity even at low temperatures.
Features and benefits:
- The STRATAPRO range can be applied in a single layer or as a finishing layer in a multilayer system. STRATA PRO M provides a mineral slate finish.
- The high mechanical strength, flexibility, thermal stability and durability of the STRATAPRO range means it can be used on roofs subject to considerable dimensional variations in both hot and cold climates.
- Excellent fatigue strength.
- Resistant to dimensional variations and active cracks which appear on cement surfaces.
- BBA certified (BBA 18/5518).
System Includes:
- Stratapro M
- Stratabase SBS
- Evatherm T rigid polyisocyanurate (PIR) insulation
- Instastik Adhesive
- Stratavap Air & Vapour Control layer
- Evaprime SA
- Deck by others

It contains a wetting agent to enable it to be applied to ‘damp’ as well as dry surfaces. |
Insulation | |
Type | Evatherm T Insulation, 1200 x 600 mm.Guidance for specification option: Evatherm T is a closed cell, CFC and HCFC-free (zero ozone depletion), rigid polyisocyanurate foam core faced board, with a Bituminous coated glass fleece on both sides. It has an exceptionally low thermal conductivity of 0.024 W/mK. Thickness: 30, 40, 50, 60, 70, 80, 90, 100, 120, 130, 140, 150 mm. Consult literature and insert requirements. |
Fixing | Instastik.Guidance for specification option: INSTA-STIK Roofing Adhesive is a specially formulated polyurethane foam adhesive for the purpose of adhering rigid insulation boards to flat roofs. |
Waterproof covering | |
First layer | |
Type | Stratabase SBS.Guidance for specification option: STRATABASE-SBS and STRATACAP-SBS consist of a special compound based on distilled bitumen modified with selected elastomers and reinforced with a non-woven spunbond polyester reinforcement, which offers good characteristics of mechanical resistance, ultimate elongation and dimensional stability. The SBS modified waterproofing compound assures good flexibility at low temperatures and excellent properties of elongation and resistance to roof movements.
