FAQs
Frequently Asked Questions about Kömmerling 88 MD
What does the Passivhaus certificate mean for a homeowner in Spain?
The certificate confirms that the 88 MD system is capable of maintaining heat or coolness inside the home with virtually no external sources (heating or air conditioning). For Spain, this means that even in the hottest weather, a comfortable microclimate will be maintained inside the home, and your electricity costs will be the lowest possible.
Why is 88 mm mounting depth considered the premium class standard?
88 mm allows placing 7 independent air chambers and three seal circuits inside the profile. This thickness creates an insurmountable barrier to external temperature effects. It is the most massive and quiet system in the Kömmerling line, created for projects where no compromises in quality are allowed.
How quiet will the home be after installing the 88 MD system?
When using special soundproofing glazing units, the 88 MD system can reduce noise levels by 50 dB. This allows comfortable living even near a railway, airport, or busy highway. Sounds from the outside world virtually disappear completely, turning your home into a zone of absolute tranquility.
What types of glazing units can be installed in such a wide profile?
The mounting rebate allows installing infill up to 56 mm thick. You can order heavy-duty triple-chamber glazing units with two selective glasses and argon filling. This also allows using thick laminated protective glass (6+6 or 8+8 mm) for maximum security.
What makes this system premium beyond its specifications?
This is a flagship product where every detail is thought through: from improved statics allowing huge sash sizes to exclusive surface finishing options. 88 MD windows look massive, solid, and emphasize the high status of the property, significantly increasing its market value.
How long will such a system last with proper care?
The 88 MD system is designed for an operational life of over 50 years. Thanks to the enormous strength reserve of the profile, reinforced armoring, and protected hardware, the window maintains its functionality and appearance for several generations. This is an investment that pays for itself with decades of impeccable service.
