Glidevale Protect VC Foil Ultra AVCL
Application

Suitable for timber, masonry or steel construction. Can be used on walls, ceilings and floors to significantly improve thermal performance and reduce air leakage in any construction.

Description

Protect VC Foil Ultra is a robust, highly reflective air and vapour control layer (AVCL), offering low emissivity to enhance the thermal performance of walls, ceilings and floors. Suitable for timber, masonry or steel construction, VC Foil Ultra provides strong insulating properties when installed facing into a still airspace. This ensures significant thermal and performance benefits when compared with conventional vapour control materials.


Features and benefits:

  • Delivers an airtight system with sealed laps.
  • Excellent air and vapour resistance.
  • Helps avoid condensation risk in accordance with BS 5250.
  • Available with integrated tapes for quicker installation and reliable, effective joint sealing.
  • Low emissivity reflective surface enhances the thermal performance of the structure when used in a still air cavity.
  • Corrosion and damage resistant reflective surface.
  • Excellent nail tear resistance.
  • High tensile strength, tough and durable.
  • Easy to cut and lightweight to handle.
  • BM TRADA independently certified for all applications and compliant with Building Regulations.
  • Class 1 surface spread of flame to BS 476-7.
