A multi-coat render system, incorporating glass-fibre meshcloth on a panel background and webersil TF top coat.
A multi-coat render system, incorporating glass-fibre meshcloth on a weber approved substrate board, and a webersil TF top coat.
Features and benefits:
The installation must be capable of resisting all dead loads and design live loads, including impact and wind loads, and accommodate all thermal movements without damage.
System installation is to be strictly in accordance with Saint-Gobain Weber specification. Please note that any other manufacturer's products used within the system will invalidate the guarantee, and the performance cannot be supported.
Remedial work must be completed prior to the installation of Weber render systems.
All rendering must be in accordance with the relevant recommendations of BS 13914-1: 2005, Design, Preparation and Application of External Rendering and Internal Plastering, BS 8000: Code of Practice for Plastering and Rendering. Consult manufacturer for further details.
Aquapanel Exterior should be restricted to use on buildings no greater than 7.2 m in height. If this restriction is exceeded design advice should be sought from Knauf and recorded.
Timber or metal frame structure is required, including support rails suitable to receive render substrate boards in accordance with manufacturers recommendations, providing an in-plane and of adequate thickness for appropriate support and stiffness (limit mid span deflections L/200 and cantilever deflections to L/150. Board mid-span deflections should be limited to L/500) to receive weberend MT reinforced render system within the stated deflection limits or edge protrusions.
Prior to installation of the weberend MT system, ensure the manufacturer of the proposed approved substrate boards are contacted to obtain their fixing recommendations and ensure the boards suitability in withstanding the necessary wind load requirements for the specific project.
To be applied in two coats, incorporating meshcloth insulation board. Apply 2–3 mm thick, incorporating weber meshcloth. Allow for partial take-up then apply further 3 mm to form a nominal 6 mm thick monolithic coat. Further application instructions are available from the manufacturer.
