BPP Polymer Modified Bitumen Membrane
Iran BPP Polymer Modified Bitumen Membrane Manufacturer
BPP is a product proving excellent quality based on a special formula containing APP (Atactic Polypropylene) modified bitumen developed by RAHA BITUMEN Co. It is reinforced by glass fiber mats and a non-woven polyester layer. The basic materials of this product are fully provided in accordance to related standards by RAHA BITUMEN Co subsidiaries.
Varieties of BPP Polymer Modified Bitumen Membrane
BPP Polymer Modified Bitumen Membrane is available in two options. The first model is an ordinary one suitable for surfaces planned to be fully covered after the installation of the insulation material, whereas the second model is covered by an aluminum foil idea for insulation of surfaces which are not to be covered after the installation of the insulation material.
The aluminum foil applied on external building surfaces reduces considerably undesired thermal absorption by reflecting the UV radiation.
Application of BPP Polymer Modified Bitumen Membrane
BPP has a broad application for insulation of various roofs and surfaces, kitchens, sanitary units, bathrooms, building foundations, swimming pools, fountains, etc.
This product can be applied on divergent surfaces made of bitumen, metal, stone, and bricks.
Storage of BPP Polymer Modified Bitumen Membrane
The insulation material provided in rolls should be kept away from the sun and on a flat space in an upright position next to each other.
Precautions
Make sure that all surfaces and even the concrete applied as the building material are perfectly dried; otherwise, the insulation material will lose its adhesive function as a result of evaporated moisture penetration into the insulated surfaces.
If the construction operations are to be continued, the insulated surfaces should be covered properly.
Standard
This product has been manufactured in accordance to regulations of roofing insulating quality control standard No: 3885-3 under the authority of Iran Institute of Standards and Industrial research.
Surfaces Suitable for Installation
This product can be installed on concrete, metal, stone and brick surfaces.
