Supaflo Summit
Verified by manufacturer 5 months ago
A strong, durable levelling screed for high rise applications.
Application
- Supaflo Summit can be used on steel frame, concrete frame, lightweight steel and masonry construction.
- Can be installed as a bonded, unbounded or floating screed.
- Suitable for high rise residential and commercial projects.
- Can be used to meet Building Regulations Approved Document E acoustic performance requirements.
Supaflo HTC should only be used if the building envelope is complete; doors and windows should be in place and must be closed for the first 24 to 48 hours after installation to prevent drafts blowing across the surface of the screed.
For unbounded applications Supaflo SUMMIT should be installed on unfolded polythene sheeting of ideally 500 gauge or a damp proof membrane (DPM) if the subfloor comprises in situ concrete.
For floating floors, including those containing an under floor heating system, a separating layer (polythene sheeting) should be placed on top of the insulation, this may be in addition to a DPM lower in the floors construction.
Supaflo SUMMIT should only be used if the building envelope is complete; doors and windows should be in place and must be closed for the first 24 to 48 hours after installation to avoid excessive drying in the early life.
