LF uPVC-VCD • High performance plastic
Application
The Series LF uPVC-VCD is an exceptionally low leakage volume control damper, designed for use in highly energy efficient buildings and proven in independent tests to have a leakage over 70% below that currently required by Part L of Building Regulations.
Material
- Extruded rigid uPVC frame and blades
- Aluminium blade cores
- Stainless steel seals and fixings
Composition
The plastic construction:
As with all HVC volume control dampers, the drive system is fully protected by being enclosed within the frame. This avoids it coming into contact with dust and debris which would adversely affect performance and warrant more frequent maintenance. LF uPVC VCDs are now available with low pressure and high pressure specifications.
- Serves to make the whole damper a thermal break, as opposed to some rival products which attempt to modify an existing metal VCD design using thermal breaks.
- Is corrosion resistant. Perfect for coastal areas, chlorinated atmospheres such as swimming baths, and anywhere dampers may be exposed to elevated moisture levels.
