INSUTECH SBS ANTIROOT is an elastomeric Modiﬁed Bitumen Membrane used for waterprooﬁng roof gardens and green areas. It is manufactured in a high-tech calendaring process, which involves the saturation and coating of a heavy-duty polyester carrier with a SBS elastomer-modiﬁed bitumen compound. Anti-root additives are included in the compound to allow the membrane to better resist the piercing force created by the growth of roots. This compound, thanks to its special formula, features an excellent resistance to UV ray ageing and allows the membrane to be walked on during application. The SBS modiﬁers are used to improve the thermal, chemical and ageing properties of the bitumen compound. Meanwhile, the mechanical characteristics such as tensile strength, elongation and tear resistance are boosted by the non-woven polyester carrier, which acts as reinforcement to the product.
The lower surface of the membrane is laminated with a thin thermo-fusible polyethylene ‘burn-oﬀ’ ﬁlm. The membrane is available with a wide range of upper surface ﬁnish options including diﬀerent colored slates, aluminum foil, sand and polyethylene ﬁlm.(click here to see the color guide)
- Excellent resistance to root penetration
- Absolute impermeability to water
- Thermal resistance under a wide range of temperature fluctuation
- Excellent U.V. resistance
- Ease of adhesion to a wide variety of surfaces
INSUTECH SBS ANTIROOT membranes are used for a wide variety of waterprooﬁng applications where resistance to roof penetration, high mechanical stresses and constant movement are required, such as:
• roof gardens & green areas
• rooﬁng or re-rooﬁng for single or multi-layer systems
• sloped and ﬂat roofs.
All Modiﬁed Bitumen Membranes should be stored in an upright position in a dry, ﬂat and ventilated storage area away from direct sunlight.
