The similarity is not just from your perspective. The installation depth of the profiles (by the way just like the number of chambers) is not a quality feature. I do not know how Salamander and Aluplast compare qualitatively. In principle, I would always prefer MD over AD. The recyclate content makes subsidy policymakers happy and does not harm the product.

There are a gazillion space-age technologies, all of which share the fact that in advertising speak they have a double turbo glossy effect, without offering any added value in everyday practice. Exceptions may also prove this rule, but a plastic window remains a plastic window remains a plastic window and as far as it should be white, it’s all the same. For colored ones, I recommend Gealan, and for stress-bearing elements (front door, lift-and-slide doors and the like) better aluminum.

In practice, the installation must be carried out by experienced professionals, only that brings an advantage to the customer. Whether on the patient paper one provider states ISO 0815 and the other DIN EN 4711: paper remains theory, you have to keep a sharp eagle eye on the smurfs at the construction site.

I have already decided that I will be there during the installation. The only question is how I can recognize a black sheep or a lazy Smurf.

The best ventilation concept is useless if the U-values are not adequate.
That is exactly why it is not sufficient for funding, because the thermal bridge verification will fail.
The temperature may even be lowered due to the airflow.



Installation according to RAL recommendation is often stated in offers, but is then often ignored.
I believe that over the years I have never had an installation that I did not reject for KfW funding.

Basically, the mounting systems must have approval according to the state building code.
This is usually not the case when products are combined indiscriminately because they are cheap.
Individual proofs generally fail due to the calculated meter lengths over the Sd value.

There is probably hardly any system left that works with silicone on the outside. (Würth once had an approval, so I am a bit cautious.)
Otherwise, the trio compressible tapes from Würth or Illbruck are sufficient on a GLATTSTRICH.
Beads are decorative and do not have to be applied with acrylic. Especially since often the wrong 3-flank sealing is done anyway.
The driving rain protection as well as the vapor barrier are beneath the beads. The beads themselves have no approval, which often also applies to frame extensions. Therefore, such parts are usually not pre-assembled, because the manufacturers often pass the buck to the installers.

Have the Uw values named and the test report for the standard window (DIN EN 14351-6 :2006+A1:2010 ) provided,
often only the Ug value is given. According to the Energy Saving Ordinance, nobody cares about that anyway.
As a rule, I also request a performance declaration from the manufacturer or supplier with a signature.
Serious companies have no problem with this. It is important here that the positions in the order are clearly assigned to the Uw values.

The number of chambers can be significant; 5 are usually so poor here that the reinforcement in the sashes is omitted and the glass is glued in the sash frame instead. Great, if a bird didn’t know that. Bad luck if an old profile was put on the market like this and a completely new window is required because the profiles are no longer available.
