MIDA Top PV200S5, 5.2 mm SBS membrane for roof finishing — 5 m² roll

The top layer of a flat roof remains exposed to sun, rain and temperature changes. A bitumen cap sheet is designed for precisely this role. An appropriate bitumen compound, reinforcement and finish create a material that completes the waterproofing on the weather side. For the owner, this means a functional covering without a high profile or a change to the building’s understated form.

Many cap sheets have a mineral surface finish. It helps shield the bitumen compound from UV radiation and gives the covering its characteristic appearance. This is an important distinction from membranes intended solely for use beneath other layers. A cap sheet must perform outdoors, so its construction answers a different set of requirements. The owner gains a finished roof surface that can be matched to the intended use and the complete waterproofing design.

SBS-modified versions offer flexibility useful when thermal conditions change. Reinforcement affects the strength and stability of the finished product. Together, these features help match a membrane to a new roof or a suitable refurbishment solution. Some products are intended for single-layer systems and others for multi-layer build-ups; their documentation defines the role. The user can therefore obtain a covering suited to the building, without judging the material only by granule colour or thickness. Appearance and function can form one considered solution.

On the relevant versions, a mineral finish gives the surface texture and shields the bituminous layer.

The low covering height helps retain the simple form of a roof concealed behind a parapet.

The choice of reinforcement allows the mechanical properties required by the roof build-up to be considered.

Refurbishment products allow renewal of the surface to be planned according to the existing roof’s condition.

Cap sheets are used on garages, homes, ancillary spaces and industrial buildings in accordance with the product’s intended use. They particularly suit buildings where the covering should stay low and discreet, for example behind a parapet. In refurbishment, they provide a renewed surface designed for exterior exposure. Building users can then focus on the purpose of the space below: storing a car, running a workshop or everyday home life. A correctly selected top layer completes the build-up and gives the surface its intended practical function.
