Aluminum window with triple glazing at 200 euros in Germany

[Woodcutter]

Why do they communicate only on Ug, when the interesting value is Uw?

Perhaps because the aluminum chassis is, whatever we do, very conductive of heat ...


For DV / TV issues, Germany is not France (power carried by light) and the decrease in the g factor is only felt when the house is designed to recover calories by sunshine (glazing surface due south, reception area and storage capacity).

I thought I posted on this video http://webcast.yourglass.com/tri/ but according to my research on the forum not.

I found it instructive.

Good night.

Triple glazed aluminum frames for less than 200 euros in a DIY store in Germany: a joke? No ... the proof:

What do the "specialists" think?

ps: beware, triple glazing is not necessarily conducive to energy savings because, on the south side, it limits solar gain. This has been widely discussed here: https://www.econologie.com/forums/le-triple- ... t4570.html

Falling on it by chance, I give an opinion (the same as Bucheron).

In aluminum frames, triple glazing is really fun! Since the cold bridge caused by the metal wiped out all the efforts made in the insulation. To ban

for solar gains, triple glazing retains far IR emitted by the interior of the room better than double.

If the glass has very little visible reflection, it can actually become a greenhouse.

If the glass is treated (metallic layer, or incorporation of metals in the glass), in fact the triple glazing can become very reflective of the visible + near IR and reduce solar gain.

There is no general rule ... The thermo-radiative balance of openings is rather complicated

I recently changed my windows for double glazing. It seemed to me that
1) My posts weren't going to like the masses
2) triple glazing did not provide performance proportional to the additional cost.

Yes, well, totally agree for the glass, the problem is the chassis.

Two years ago, nious replaced the oak windows with double glazing + xenon gas and PVC frames. The result is fantastic! Total comfort. By cons I have some reservations about the life of the plastic. I would have seen a wooden plank on the facade side, because white is very messy and does not resist as well as wood against external aggressions (it can quickly get stained and plastic is too easily colonized by dirt, polens , bird lovers, acid rain and / or silicon).

hi Elephant, these are wooden pieces that support the windows

the triple glazing is very heavy and can overload some old joinery not provided for that.

This is however what they are now looking to do at the EPFZ on the side of the sunny facades, where they have even integrated exchangers: sensors / diffusers in the slabs! So that nothing of the sunshine passing through the bay windows is lost ...
