French doors in Aluplast Ideal 4000

The Ideal 4000 is Aluplast's flush profile. Frame and sash sit in one plane, without the recessed sash of the block profile, and the window doesn't need a rebate. The frame is 70 mm deep, divided inside into five chambers with a double seal, and the outer frame has a closed steel reinforcement as standard. For a complete window with glass of Ug 1.0, the system data give Uw 1.3 W/m²K — the same as the deeper Ideal 7000 NL.

Flush uPVC profile, 70 mm deep with five chambers: clean-lined, without a rebate and affordable, for windows, doors and every front door.

Two doors that open outwards from where they meet: together they give a wide opening with no fixed centre section in the way.

Where the back door layout has one door opening outwards, French doors put a second one beside it. Both doors open outwards from the middle, so the whole width can be cleared — unlike a sliding patio door or a bifold door, where part of the glass always stays in front of the opening or folds against the side. It does need room outside for two doors to swing open.

The standard size is 1,600 × 2,200 mm. That is narrower than a sliding patio door or a bifold door, but with no tracks or folding hardware — a simpler and often cheaper way to get a wide opening onto the garden if you don't need the full width of a sliding patio door.
