Tilt and turn with top light 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 standard tilt and turn window below, at a height you can operate, and a fixed pane above that fills the rest of a tall opening.

Some openings are taller than is comfortable for a tilt and turn window on its own — under a sloping roof, or in an elevation where the head of the window sits higher than you can still reach the handle comfortably. This window puts the tilt and turn sash at reachable height at the bottom and fills the rest of the height with a fixed pane above, so you get glass over the full height without a sash you can't operate.

The standard size is 1,200 × 1,800 mm, with the fixed top light taking a quarter of the height and the tilt and turn window the rest. If you do need ventilation at that height, the tilt and turn window with tilt-in top light — with a bottom-hung sash instead of the fixed top light — is the form that provides for it.
