A water-based acrylic emulsion membrane incorporating a polymer bonded glass reinforcing sheet (Belzona 9321) designed to provide seamless, flexible protection to all types of thermal insulation and cladding systems.
Belzona 3211 (Lagseal) is water, weather and fire resistant, and conforms to the requirements for a ‘Class O’ surface for ‘The UK Building Regulations 1991’ and ‘Class A’ in accordance with ‘ASTM E84’. The system provides protection from water ingress whilst its microporous nature allows trapped moisture from within the insulation to evaporate. This solvent-free, single pack system requires no mixing and is simple to apply to damp as well as dry insulation.
