Description
SOPRA-CELLULOSE PATCH is a self-adhesive patch used to close the injection holes in the restraint membrane after SOPRA-CELLULOSE cellulosic fiber insulation has been applied in the walls, roofs and ceilings.
Material Use:
SOPRA-CELLULOSE PATCH is a self-adhesive sealing patch specifically designed for use in conjunction with SOPRA-CELLULOSE cellulosic fibre insulation systems. It is used to close injection holes in the restraint membrane after insulation has been applied in wall, roof, and ceiling assemblies. The patch plays a critical role in maintaining the integrity of the vapour barrier system by ensuring a tight seal over the injection points.
System Components:
This patch is part of the SOPRA-CELLULOSE insulation system and is used in combination with SOPRA-CELLULOSE cellulosic fibre insulation and a restraint membrane. It may also be used with a web spray adhesive when applied at low temperatures to enhance adhesion.
Applications:
SOPRA-CELLULOSE PATCH is intended for indoor use in wall, roof, and ceiling assemblies where SOPRA-CELLULOSE insulation has been installed. It is particularly useful in residential and commercial construction projects that require a continuous vapour barrier and effective thermal insulation.
Application Details:
To install, ensure the restraint membrane is clean and dry. Apply the SOPRA-CELLULOSE PATCH directly over the injection holes, pressing firmly to ensure full adhesion and a complete seal. At temperatures below -5°C (23°F), a web spray adhesive is recommended to improve bonding. The patch is 152.4 mm (6 inches) in diameter and comes in rolls of 100 units, with a total roll weight of approximately 0.5 kg (1.1 lb).
Special Notes:
- Temperature Range for Installation: Service temperature is greater than -5°C (23°F). For colder conditions, use a compatible web spray adhesive to ensure proper adhesion.
- Water Vapour Transmission: Extremely low permeability with a water vapour transmission rate of 0.1 ng/Pa•s•m² (0.002 Perm), making it highly effective in maintaining vapour barrier integrity.
- Adhesive Strength: Maintains strong adhesion at both low and room temperatures, with adhesive strength of 400 N/m (2.30 lbf/in) at -5°C and 460 N/m (2.70 lbf/in) at 22°C.
- Storage Conditions: Store in a cool, dry place away from moisture, direct sunlight, and weather exposure to maintain product integrity.
This patch is a critical accessory in the SOPRA-CELLULOSE insulation system and should be used as specified to ensure the long-term performance of the vapour barrier and insulation assembly.
