Window with a dummy sash in VEKA Softline 70 AD

Softline 70 AD is VEKA's entry-level profile: 70 mm frame depth, five chambers and a Uf of 1.3 W/m²K. AD stands for Anschlagdichtung, a rebate seal. The profile works with two sealing levels, one inside and one outside; it has no third seal in the middle. That makes it slimmer and simpler than the MD versions. The rebate takes glass up to 42 mm. The design is classic, with slightly rounded edges, and the sash comes in a stepped and a semi-stepped version. The outer walls are 3 mm thick, which puts the profile in class A of DIN EN 12608. VEKA supplies it in more than fifty colours and woodgrain finishes, with grey seals. The window opens inwards: tilt and turn, side-hung, tilt-only or a door.

VEKA's entry-level uPVC window with a rebate seal: 70 mm, 5 chambers and Uf 1.3 W/m²K.

New build. Possible, but at Uf 1.3 the profile insulates less well than most of the uPVC profiles we offer. For a new build, the Softline 76 MD and 82 MD are the more obvious choice.

Renovation. Suitable, especially where depth is short: at 70 mm the frame sits less far into the wall.

VEKA Softline 76 MD. Same make, 6 mm deeper and with a centre seal: three seals instead of two. The Uf drops from 1.3 to 1.1 and it takes glass up to 48 mm instead of 42 mm. You do see more profile: 112 mm of frame and sash against 99 mm.

VEKA Softline 82 MD. The deepest Softline: 82 mm, 7 chambers in the outer frame and Uf 1.0 against 1.3. It takes glass up to 54 mm. Choose it if insulation matters more to you than a slim profile.

A dummy sash draws the outline of a tilt and turn sash in the frame, without the hardware that would let it open.

Side by side, a real tilt and turn window and a window with a dummy sash are hard to tell apart: both show a sash inside the frame. The difference is in what you can't see — there is no hinge, no tilt position and no handle in it. That makes this pane right for the spot where you want to keep the look of a tilt and turn window but don't need another opening: for example the one pane in a row of windows where the others really do open.

The standard size is 1,500 × 1,500 mm, the same as the single fixed window; in the configurator you set it to match the tilt and turn window next to it, so a real tilt and turn window and a dummy sash can sit side by side in one elevation without the sightlines jumping. If you actually want to show that a pane doesn't open — for a calmer look, or to leave a would-be burglar less to try on a vulnerable spot — the plain fixed window without a drawn sash line is the simpler choice.
