- Sealing and protection during the installation of windows and balcony doors (usage according to principle of triple assembly seam).
- Sealing of seams of concrete constructions
- Sealing of gaps of roof systems
- Sealing of gaps and seams in ventilation systems
- Sealing of gaps during building of wooden cottages.
PURS tape (polyurethane tape soaked with special solution)
PURS tape – polyurethane tape soaked with special solution that gives to tape elasticity and self-expansion properties. For convenient working covered with self-adhesive layer.
PURS is being used for sealing of seams and gaps in constructions.Features of PURS allow from one side to protect seams and gaps from atmospheric effects and from the other side provide removal of moisture that emerges inside the seam or gap.
Density 50 kg/m³ 
Endures pressure up to 600 mPa (with required compression ratio)
Temperature of usage from -45°С to + 85°С;
Steam-throughput ability not lower 0,15 mg)
Expanding up to 5 times from initial sizes.
Expanding times:
| 0°С | 10°С | 20°С | 30°С |
| 48 hrs | 15 hrs | 2,5 hrs | 30 min |
Qualitative sealing of seam can be done only in case of correct selection of tape size. Incorrectly selected tape breadth will break the sealing of seam.

| PURS 8*30*4 | 8 | 40 | 30 | 4 | 8-15 |
During selection of the PURS tape you must remember that tape doesn’t have to expand fully only to certain percent. Depending on expanding of the tape its properties change.
