Cortizo COR Vision Evolution Sliding Door

COR Vision Evolution sits between our two best-known Cortizo sliders. It has the clean, minimal look of COR Vision, with a 25mm central interlock, but its 160mm frame takes double or triple glazed units from 28mm to 44mm thick. That is what gives it a U-value from 0.88 W/m²K, against 1.3 W/m²K for COR Vision.

Each panel can be up to 3.5m wide and 3.5m tall and weigh up to 500kg, so it suits wide openings onto a garden or terrace. It can be made with one to four tracks and up to eight panels, as a pocket door that slides into the wall, or as a 90° corner that opens completely, with the corner post sliding away with a panel.

COR Vision, Evolution or COR Vision Plus?

  • COR Vision Has the slimmest look, a 20mm interlock. It takes double glazing only, with panels up to 2.5m wide and 3m tall.
  • COR Vision Evolution Adds triple glazing and panels up to 3.5m × 3.5m, in a 160mm frame.
  • COR Vision Plus Is for the very largest openings: panels up to 4m × 4m and glass up to 56mm thick.

Every Evolution door is made to measure and powder coated in-house, in any RAL colour. We check the panel sizes and glass for every design, because the largest sizes depend on the layout.

Triple glazed 6/12/6/12/6Three panes, two Low-E coatings and two argon gaps for the lowest heat loss. It is the heaviest unit, so the frame has to be built to carry it.
In every unit
Warm edge spacer
The bar that holds the panes apart around the edge. It is made from a low-conducting composite instead of aluminium, so the edge of the glass stays warmer, with less heat loss and less condensation. It is filled with desiccant, which soaks up any moisture sealed inside so the unit never mists.
Sealant
The black outer seal bonds the panes and spacer into one unit, keeps the argon in and keeps moisture out.
Low-E coating
An invisible metal-oxide layer on the inside face of the glass that reflects heat back into the room.

We specify the optimal glass configuration for each project based on thermal performance, acoustic requirements and Building Regulations compliance.
