Thermally broken aluminium system. Insulates on a par with a good PVC window, but with a noticeably slimmer frame.
Uw measures how much heat disappears through the window. Lower is better. Here are our PVC systems set against each other.
Thick outer walls often call for a deeper frame – which is why Ideal 7000 NL exists with 120 mm. Thin walls manage fine on 70 or 82 mm.
North and west lose the most heat. There it makes sense to move from Uw 0.89 to 0.66 – facing south the difference is less noticeable.
A bedroom wants tilt-and-turn for night ventilation. A living room facing the garden wants as much glass and as little frame as possible.
Should the new windows match the old, or should the facade change character? Rounded or sharp edge, white or RAL, wood-effect foil.
A window is only as good as the joint it sits in.
That is why we measure and fit it ourselvesNo standard stock. We measure at your place and production follows – which is why it fits the opening you actually have.
We do not hand the job on. The person who measures is the person who knows what happens when the opening is not quite square.
Sills, seals and adjustment are part of it. We take the old windows away with us.
We guarantee the quality of the products. Windows and doors are covered by the manufacturer warranty – the exact terms are stated in your quote.
