Equus Soprema Sopraseal Stick VP
Description

SOPRASEAL STICK VP-S FR is a self-adhesive vapour permeable air barrier membrane used in wall and roof constructions. It prevents air leakage through the building envelope and allows moisture to escape before causing any material damage to the structure.

SOPRASEAL STICK VP-S FR has trilaminar polypropylene highly UV stable facer and a self-adhesive underside covered by a silicone release film, easing the installation process.

It can be used on most building surfaces, such as masonry, concrete, wood, gypsum, rigid insulation panel and OSB surfaces.

Key Features
  • Continuous air barrier to reduce uncontrolled leakage and moisture risks.
  • Self‑adhered, no primer, fewer mechanical fasteners, faster installation.
  • UV exposure window for construction sequencing (up to 180 days).
  • High tear strength and low‑temperature flexibility to withstand site handling and weather.
  • Cost‑Effective Performance – Delivers premium air and moisture control at a competitive price point compared with similar vapour‑permeable membranes, offering excellent value without compromising quality.
  • Aligns with NZBC performance expectations.
Scope of Use
  • SOPRASEAL STICK VP-S FR is used as a vapour permeable, air barrier membrane used in wall construction.
  • This product can be used on most surfaces, such as masonry, concrete, wood and exterior gypsum board.
  • Where insulation is used in the exterior wall assembly, the air barrier can be used on either side of the insulation as it allows vapour diffusion.
  • Can be used as an air barrier in other areas of a building with the written approval of Equus Industries Ltd

     

Statement of Building Code Compliance
  • B2 Durability — B2.3.1 (b) SOPRASEAL STICK VP-S FR has a durability of at least 15 years, when installed with the correct
    specification, installation and maintenance.
  • E2 External moisture — E2.3.2, E2.3.5, E2.3.6, E2.3.7 Test data, together with in-service history internationally, of the correctly
    installed SOPRASEAL STICK VP-S FR membrane over correctly designed and constructed substrates, show that the air barrier
    membrane successfully resists the ingress of moisture, and prevents external moisture accumulating and causing degradation of building elements.
  • F2 Hazardous building materials — F2.3.1 Well known experience with the type of materials used together with in-service history, show that SOPRASEAL STICK VP-S FR complies with this performance requirement. Refer to SDS.
  • H1 Energy efficiency — H1.3.1 (b) Test-data shows that SOPRASEAL STICK VP-S FR provides the building with limited
    uncontrollable airflow.
