Imperpuma Plus PY48
Waterproofing sheet of 1 m x 8 m x 4.8 Kg/m2 of bitumen modified with elastomer (APP). With polyester felt armour, finished on both sides with non-stick polyethylene film. Waterproofing bituminous sheet ideal for waterproofing of roofs type LBM-48-FP. It acts as single and double skin under heavy protection. It serves in turn for water tightness in buried structures and, as lower sheet in gardens’ roofs.
Additional information
Composition
It is composed of polyester felt armour, mast modified with elastomeric finished with non-stick polyethylene film on both sides
Features and applications
- Single-skin layer system under heavy protection.
- Double-skin layer system under heavy protection.
- Double-skin system inferior sheet in open air.
- Sealing sheet in buried structures.
- Lowe sheet in green areas covers.
Instructions for use
Place by adhesion by blowtorch.
Cautions and recommendations
- Not recommended for upper sheet in open air double-skin systems nor for single-skin layers or upper sheet in green areas’ covers.
- Store in vertical position.
- Away from open air and humidity.
- Do not apply under -5ºC.
- In general terms, the protection of a waterproofing system should be carried out as soon as possible, especially when dealing with non-adhered solutions, which should be away from open air for at least more than 72 hours.
Packaging
25 rolls per pallet.
Maximum time of storage: 2 years, away from open air at temperatures above +5ºC.
