Passive House Entry Door

Groke entry doors U-Factor range from .257 all the way down to an impressive .13, making them ideal for use as a Passive House Door. 

All Groke door configurations meet European air leakage Class 4, with the exception of double in-swing doors which meet Class 3 criteria, still within the Passive House performance requirements.  

While Groke custom doors are very suitable for Passive House doors, they are equally at home in other applications from new construction to retrofit... and of course deep energy retrofits.  Whether the building is old or new, modern in style or traditional, everyone appreciates a finely crafted door that offers superior thermal performance, serious security protection, and long term durability all in one beautiful package!
