Hello everyone, next week our windows are going to be planned, and I want to gather some information beforehand about what we should choose. A window manufacturer we spoke with a few months ago recommended ALUPLAST IDEAL8000 PVC windows. The specifications are:
- 6-chamber system
- Installation depth: 85 mm (3.3 inches)
- Steel reinforcement fully enclosed in the frame
- Misalignment lock (tilt-and-turn windows)
- Hardware equipped with two anti-burglary locking points per window sash
- System with 3 seals
- Glazing with insulating glass units up to 51 mm (2 inches) thick
- Standard glazing is 4th/18Ar/4/18Ar/4th [Ug=0.5]
- Option for concealed hardware available
- Recommended for building passive houses
We are planning a 170 sqm (1,830 sq ft) single-family house, built with T10 solid bricks. No ventilation system and no additional insulation. The bricks comply with the energy-saving regulations but not with KFW standards. There will be a wood stove in the living room. I have considered the following three points:
- Sound insulation
Our house will be built on a moderately busy street. A few hundred meters away there is a school, which means that a few buses pass by on the north side of the house in the morning and at noon. Otherwise, the area is fairly quiet. Aluplast states the IDEAL8000 window has a sound insulation rating of 48 dB. Does this mean that if I assume 100 dB from the street noise, I subtract 48 dB, and the remaining 52 dB would be audible inside the house? Of course, this is just theoretical, but having a rough idea like this would probably help me. I would like the interior to be quite quiet, so good sound insulation is important. There are no significant noise sources on the other sides of the house.
- Thermal insulation
Since our house will not meet KFW55 or similar standards, we have no special requirements. IDEAL8000 is triple-glazed and “suitable for a passive house” (which sounds like marketing to me). We will have five large patio windows on the south side, which will by far be the warmest side. There is an additional option called “warm edge” for the windows. As I understand it, the edges of the glass inside the window are additionally insulated by the frame. Is it possible that the window insulates “too well” and this could cause, for example, condensation or other unwanted effects?
- Security
We will live in a rural area where there are practically no break-ins. Still, I would like somewhat more than the usual protection. After all, you only build once, and the windows should remain in place for a long time. Therefore, I would choose the additional option of concealed hardware. Does that make sense, or are these hardware solutions easy for burglars to overcome? I understand that a burglar will get in if they really want to, but I would like to delay them as long as possible.
Thanks in advance for your opinions.

For a window with argon filling and triple seals, it seems illogical to forgo the relatively affordable warm edge spacer. For cost reasons, I would rather consider using a Ug value of 0.6 with a warm edge spacer. The insulation performance would be the same.

For a window with argon filling and triple seals, I would find it illogical to skip the relatively inexpensive warm edge spacer. I would rather consider, for cost reasons, whether to go with a Ug value of 0.6 and a warm edge spacer. The insulation value would be the same.Thank you for the reply. No, it wasn’t a mistake. We can get this type of window quite cheaply, which is why I asked whether installing "overly well" insulated windows is possible and if it really provides any added value.

boxandroof7 Jan 2020 16:50You cannot install high-quality windows in new construction. Warm edge spacers are a relatively inexpensive measure; whether it is worth it depends on the price and heating costs. The "risk" of condensation forming on the windows decreases with warm edge spacers.
You are contradicting yourself on all points.
Soundproofing is important. There are windows with special sound-insulating glass. But you are building with "lightweight" bricks. Therefore, you should change the windows and use calcium silicate bricks with external thermal insulation composite system (ETICS) or a brick veneer facade.
The windows are also not really resistant to break-ins. There are categories for that. Search online and order accordingly.
You don’t need to worry about condensation. More important is shading in summer.

The number of chambers is a misleading argument. I have already looked at the profile and found nothing to criticize about it. With the MD version, you are well positioned.
