The manufacturer's system values depend on the selected combination of profiles, reinforcement, hardware and glazing. Uf applies to the frame, not the entire window. Triple glazing can be used where sash dimensions are suitable. The 42 mm glazing thickness is VEKA's official system limit; the dimensions and performance of the specific assembly can be stated according to its individual technical configuration.

Frame extensions

Dimensions: extension height × profile depth. Match the element to the exact profile system, not just to a similar size.

• 15 × 70 mm

  Frame extension matching the 70 mm frame depth, in white and foil-laminated finishes. The manufacturer's connection detail uses sealing tape.

  Manufacturer's catalogue · 2.69

• 30 × 70 mm

  White and foil-laminated finishes. The drawing shows 38 × 15 × 1,5 mm steel reinforcement and sealing tape at the joint; whether reinforcement is used depends on the structural design calculations.

  Manufacturer's catalogue · 2.69

• 45 × 70 mm

  White and foil-laminated finishes. The drawing shows 38 × 30 × 1,5 mm steel reinforcement and joint sealing tape; whether reinforcement is required is determined by the structural design of the assembly.

  Manufacturer's catalogue · 2.69

• 100 × 70 mm

  White and foil-laminated finishes. The drawing shows 38 × 30 × 1,5 mm steel reinforcement and joint sealing tape; whether reinforcement is required is determined by the structural design of the assembly.

  Manufacturer's catalogue · 2.69

• 250 × 70 mm

  White and foil-laminated finishes. The manufacturer specifies 38 × 30 × 1,5 mm reinforcement and EPDM joint sealing tape. The substantial extension height requires the fixings and reinforcement to be designed for each assembly.

Couplers, corner and tubular connections

• Flat coupling profile · 70 × 2,5 mm

  For vertical joints only. The manual shows white, brown and caramel base colours; the flat component alone does not provide structural reinforcement.

  Manufacturer's catalogue · 2.86

• Coupling profile with provision for reinforcement · 70 × 20 mm

  White and foil-finished versions. The manufacturer's table lists a 50 × 10 × 1,5 or 3 mm steel insert; the appropriate reinforcement must be selected according to the dimensions and loads of the connected units.

  Manufacturer's catalogue · 2.86

• Mini coupling profile · 8 × 15 mm

  Shown with a 2 mm joint gap in the drawing. The manual lists it for all VEKA systems, in white and brown base colours. It does not provide structural reinforcement on its own.

  Manufacturer's catalogue · 2.85

• Coupling profile · 17,5 × 20 mm

  The drawing shows a 2 mm joint gap; white and foil-laminated finishes. The dimensions refer to the individual coupling profile, not the full frame depth. On its own, it is not a reinforced system coupling profile.

  Manufacturer's catalogue · 2.85

• Horizontal coupling profile · 14 × 35 mm

  For horizontal use only, in white. The 14 × 35 mm designation refers to the individual profile; the drawing shows a 2 mm joint gap.

  Manufacturer's catalogue · 2.86

• System coupling profile · with two small cover profiles

  Vertical use only. Two 8 × 45 mm cover profiles, an overall depth of 86 mm with a 70 mm frame, and a 30 mm coupling zone. The assembly comprises 49 × 25 × 1,5 mm steel reinforcement, a 70 mm spacer, a sealing plug, an end cap and a fixing system.

  Manufacturer's catalogue · 2.81

• System coupling profile · with large and small cover profiles

  For vertical use only. 40 × 45 and 8 × 45 mm cover profiles; an overall depth of 118 mm with a 70 mm frame. With 70 × 25 × 1,5 mm steel reinforcement, a system spacer, sealing plug, end cap and mounting system.

  Manufacturer's catalogue · 2.82

• System coupling profile · with infill profile

  Vertical connection with a 40 × 45 mm cover profile and a 20,5 × 22 mm infill profile. The infill profile is made of recycled material, with no specified colour. Requires 70 × 25 × 1,5 mm steel reinforcement, a 70 mm system spacer and a fixing kit.

  Manufacturer's catalogue · 2.82

• Horizontal system coupling profile · 49 × 76,1 mm

  Horizontal use only. 76,1 mm is the base profile dimension, not the window system depth. It comprises a small or large cover profile, a spacer for the 70 mm frame, steel reinforcement with a 49 × 25 or 70 × 25 mm cross-section and a wall thickness of 1,5 mm, and a fixing plate. The manual lists it as available on request.

  Manufacturer's catalogue · 2.83

• Horizontal reinforced coupling profile · 142 × 125 mm

  Horizontal use only, with a 70 mm frame connection. The drawing shows 80 × 80 × 5 mm reinforcement, a gasket and the appropriate glazing bead. White/foil-laminated; the manual lists it as available on request.

  Manufacturer's catalogue · 2.84

• Vertical reinforced coupling profile · 103,5 × 85 mm

  For vertical use only, with a 70 mm frame connection. With steel reinforcement of 60 × 40 mm cross-section and 2 or 3 mm wall thickness, and a system spacer. White/foil-finished; the manual lists it as available on request.

  Manufacturer's catalogue · 2.84

• Vertical structural coupling profile · 118 × 40 mm

  For vertical use only, with a 70 mm frame connection. The manual shows 80 × 10 × 2 mm reinforcement and a spacer, with an additional reinforcement variant. The specific steel variant must be selected based on structural calculations and the manufacturer's table.

  Manufacturer's catalogue · 2.85

• 90° · 75 × 75 mm

  For a system depth of 70 mm, for vertical use only. White/foil-laminated, with 40 × 40 × 2 mm steel reinforcement and a mounting system. 75 × 75 mm refers to the overall dimensions of the corner component.

  Manufacturer's catalogue · 2.87; 2023: 6.46

• 135° · 72 × 83,6 mm

  For vertical use only, white/foil-laminated. The drawing specific to SOFTLINE 70 shows a 70 mm frame connection, 40 × 10 × 1,5 mm reinforcement and a corner joint cover for the seventy-millimetre depth. An assembly from another system cannot replace this.

  Manufacturer's catalogue · 2.87

• Variable angle · 80 × 70 mm

  Tubular profile and connecting profile used together, vertically only. White/foil-laminated, with Ø 48,2 × 2,5 mm steel reinforcement, a seal and an assembly system. For the finish laminated on one side, the source specifies a special foil and a 90–170° range. Fabrication deductions depend on the angle and are not fixed values.

  Manufacturer's catalogue · 2.89–2.91

• 90° · 87 × 87 mm

  VEKA's 2023 profile catalogue also lists it for a system depth of 70 mm. For vertical use only, in white/foil-laminated finishes, with 40 × 40 × 2 mm steel reinforcement and a mounting system. 87 × 87 mm refers to the overall dimensions of the corner component; the connection drawing for the frame is the governing reference.
