ᐅ Front door with double or triple glazing

Hello

I couldn’t really find a suitable main topic to ask my question, so I’m just posting here!

We are building a new house and have now received quotes for windows and front doors!

- We are going with triple-glazed windows; the only remaining decision is whether to choose a frame depth of 70mm (2.8 inches) or 86mm (3.4 inches). I believe the 86mm frames include an additional seal. I think we’ll choose the 86mm option, which costs about 1500 euros more overall for all the windows.

- The front door offered to us is a 96mm (3.8 inches) aluminum door with a glass strip (around 30cm (12 inches)) in the middle and a fixed glass side panel. The door is currently offered with double glazing, U-value = 1.1, or for 130 euros more with a thermal insulation core and triple glazing, U-value = 0.5.
Is the extra 130 euros worth it for the triple glazing in the front door?

I appreciate any advice

Best regards

Martin

I would rather invest the 130 € in a better door... Seriously, how is the U-value of the entire component (door) supposed to change? An aluminum door would not be my first choice.

Uh, so what kind of door do you want to choose then? The one in the offer already costs nearly 4000.

Hello!

What is your main concern? The cost (3% of the total amount)?

Or energy efficiency? (In our case, the hallway is only minimally heated, and the glass area in the door is quite small.)

If so, go for triple glazing – it might help reduce condensation at that point.

PS. We have a wooden door with glass inserts and a matching sidelight. It looks great and was somewhat cheaper – but that’s without considering the then quite useful entrance canopy.
