Stucco Lite Soffit is a non-insulated soffit finishing system suitable for canopies, through-ways, balconies, large overhangs. Specifically designed to economically facilitate the finishing of overhead soffits while controlling and preventing vapour diffusion into the adjacent soffit structure. The system consists of a cementitious trowel applied moisture barrier coating glass fibre reinforcing mesh, topped with base coats, and a finish texture coat which can be selected from any one of the available Durex® Architectural Coatings.
- Excellent moisture resistance
- Cost effective solution
- Allows for use of a wide variety of finish textures
- Applicable to a multitude of substrates
Stucco Lite Soffit system can be used for new and restoration work and is an effective solution for commercial and residential construction. It is highly recommended for use for interior and exterior soffit and protected overhead applications.
