Air, Water and Wind Tightness
It is common belief that a security door is not suitable as an entrance to a home, or a condominium, when exposed to weather conditions.
OKEY overturns this logic by redesigning its structure making it closer to that of a window, combining the highest levels of security with optimal air, water and wind tightness features.
All of our doors are fitted with 3 groups of balloon-shaped double lip seals, ensuring a close to airtight seal when the door is locked. They are mechanically and magnetically fixed (not glued) to both the frame and leaf.
To further increase the thermo-acoustic insulation and water-resistant properties of any of our models, it is possible to equip them with one of our exclusively designed doorsills.
Whenever required, anti-condensation solutions, in the form of special insulating thermal-break profiles, are also available.
