The ALU+ SL10 and SL12 are "through the frame" vents manufactured using aluminium extrusions.
The internal controllable vent provides upward ventilation to avoid draughts and the canopy, fitted with a flyscreen, provides excellent weather performance and prevents flies and other insects from entering the building
The Maximum slot height is 12mm using a standard foam seal and both the SL10 and SL12 are suitable for uPVC, timber and aluminium windows. A combustion air version is also available.
These vents are also available in a wide variety of finishes (Ral, Syntha Pulvin, Interpon, etc)
