Construction
Discover a unique carbon construction, designed exclusively for entrance doors, delivering up to 50 % less leaf warping compared to conventional solutions.
DESIGN YOUR ENTRANCE
WHY CARBONCORE?
The world’s most advanced carbon construction
A rigid yet lightweight structure made of carbon fibres—several times stronger than steel—ensures exceptional resistance to loads and long-term reliability without compromise.
CarbonCore delivers up to 50 % less door leaf warping compared to the most widely used door construction in Germany, ensuring stability even under extreme weather conditions.
Record-breaking sealing
Magnet WeatherSeal achieves record performance in laboratory testing, allowing CarbonCore doors to seal like a wall—effectively preventing drafts and moisture.
CarbonCore ensures outstanding structural strength and stability, with RC2 burglary resistance class as standard. Your entrance door is designed for maximum security and peace of mind.
CarbonCore enables impressive dimensions and countless personalization options, enhanced by handcrafted accessories, distinctive handles, and timeless aesthetics for refined elegance.
PIRNAR CARBONCORE
Outstanding laboratory test results for CarbonCore construction
Laboratory measurements* and comparison with the most commonly used entrance door construction on the German market confirm the absolute superiority of CarbonCore. When measuring deformation caused by temperature differences between the interior and exterior sides of the door leaf, Pirnar’s patented CarbonCore construction achieves up to 50 % lower warping values.
Thanks to the reduced risk of deformation—even in exceptionally large dimensions—Pirnar entrance doors are an ideal choice for all climates, from Alpine and Scandinavian to Mediterranean and desert environments.

SEALING PERFORMANCE RESULTS
Record-breaking sealing performance of CarbonCore doors
CarbonCore features the advanced Magnet WeatherSeal system, which achieved an exceptional watertightness rating of 9A in laboratory testing. At a pressure of 600 Pa—equivalent to wind speeds of 114 km/h—the door maintained complete watertightness. This represents up to six times higher resistance compared to standard entrance doors.
