Description

EXAMPLES

Example 1

[0134] Poly(vinyl butyrate) (PVB) foil material was produced from granules of recycled PVB, originating from car windows. Using an extruder and a dye, the PVB granules were shaped into rolls of 1 m wide with a thickness of ca. 2 mm. White and grey rolls were produced.

[0135] The rolls of foil material were rolled out and applied as roofing and flashing on a roof with raised edges. Due to the physical properties of the material, a single piece of material could be shaped to act both as roofing and as flashing material, covering the flat roof surface as well as the raised edges of the roof, without the need of applying separate pieces or other materials as a drip edge or flashing.

[0136] On one roof, the foil was applied to the surface using polyurethane (PU) adhesive, without overlap between adjacent foil strips. On the other roof the foil was applied to the roof surface using screws and washers, and an overlap between the foil strips was created. The overlapping regions were bonded using ethanol and/or hot air.

[0137] Both roofs were filled with water, and no leakage was observed.
