SBS cap sheet MIDA Top PV200S5, 5.2 mm — roll of 5 m²

A bitumen cap sheet forms the outer layer of a roof covering, directly exposed to sunlight, rain and temperature changes. Its selection affects both watertightness and the durability of the complete roof build-up. At SteelProfil, we help compare cap sheets and match them to a new roof, an upgraded roof area or repairs to an individual section of the covering.

Bitumen cap sheets often have a mineral finish that shields the bituminous layer and gives the surface its appearance. Products differ in thickness, reinforcement and the properties of the bitumen compound. We match these features to the intended application, because performance depends on their combination. Compare the specific product and its intended use, rather than treating all mineral-finished rolls as interchangeable.

SBS-modified versions can provide high flexibility within the limits specified by the manufacturer. This is useful for roof coverings exposed to changing temperatures. Compatibility with the underlay and substrate is equally important. Depending on the product, a membrane may form part of a multi-layer system or be intended for a particular single-layer solution. We help select a version that meets the documentation and the chosen roofing method.

Bitumen membranes combine protection across a large roof area with detailing at parapets, chimneys and rooftop equipment. This allows continuous protection to be planned around different shapes. They can suit garages, halls and commercial buildings where the complete system meets the conditions of use. The fixing method must match the product’s intended use and substrate requirements. On a small garage, roof-area protection can also be coordinated with edge finishing and drainage.

• A suitable outer finish protects the waterproofing layer under roof exposure conditions.
• A flexible material helps connect the roof plane to its vertical details.
• Selection for the complete system helps create a consistent protective layer on a new or refurbished roof area.

For refurbishment, a description of the existing roof helps identify the right membrane category and the materials required. For new construction, the specified layer build-up is the starting point. SteelProfil’s wider range includes first- and second-grade panels and sheet metal, with selected materials available from stock. We check availability of the particular cap sheet against the required quantity and specification, so the purchase matches the planned work.

Competitive prices and frequent offers help you put together roofing materials at a favourable cost. Our quotation allows for laps and details requiring upstands, rather than roof area alone. We can combine a suitable cap sheet with underlay and ancillary materials. This makes it easier to compare the cost of the complete solution and choose a covering whose properties match the building and the planned installation method.
