SuperFOIL SFTV Insulation - The Sound Solution, York, UK

SFTV resists the passage of moisture through wall, ceiling and floors. Aiding the achievement of a u-value to meet or exceed building regulations

Main benefits

• Simple to install
• CFC free
• Prevents mould & damp staining
• Prevents condensation
• Fast Installation
• Enhances thermal resistance

Key Features

• Resists the passage of moisture through wall, ceiling & floors
• Improves the general air tightness of the building
• Restricts the passage of warm, moist air from within the building from permeating into the structure or the roof.
• SFTV is a general purpose membrane suitable for preventing condensation which can lower the performance of insulation.
• Suitable for wall and roof applications
• Vapour resistance greater than 200MNSG
• Permeability rating lower than 1.0
• Helps to prevent mould and damp staining
• Can be used to enhance U - values in both new build and renovation projects.

Installation

SFTV should be installed on the "warm" side of the insulated structure, with special care being taken to ensure that all seams and holes are sealed effectively to render the whole structure moisture vapour proof and to improve the thermal performance. It is important that SFTV should be installed as a continuous barrier in order to prevent vapour entering the wall or the roof.

Fixing & Jointing

All overlaps should be a minimum of 150mm and be sealed using sf jointing tape. Particular care is required when sealing around penetrations. Were the barrier is breached by construction elements, the aperture should be sealed with SF double sided tape.

Packaging

All rolls are packaged individually - sealed with tape and separately labelled for ease of identification

Storage & Handling

SFTV should be stacked on end and protected from extremes of weather and temperature. Care should be taken to ensure that rolls are not physically damaged at any time.
