Balcony and terrace doors from a Finnish manufacturer
Our range of balcony doors includes IOU/A and IPO/A aluminum doors as well as E70_IOU and A80_IOU exterior doors, which are suitable for balcony or terrace doors. All balcony doors are available in 130, 150, 170 and 210 mm frame depth and the door measurements can be selected freely.
Aluminium surface balcony doors
The two types of doors differ in their features. IPO/A doors are double-leaf doors, one opening to the inside and one to the outside. IOU/A doors have only one door leaf opening to the outside. Due to the double doors, IPO/A doors have better soundproofing.
The pulling handle of an IOU/A balcony door.
IOU/A, and IPO/A doors are always equipped with an espagnolette lock system and venting hardware. Venting hardware enables the door to be locked in the ventilation position. The door closes and opens by turning the handle. A multi-function espagnolette can be installed at the factory as an option, so the door has a daytime function and the door can also be closed by pushing. As standard IOU/A and IPO/A doors have a Primo 83 handle and an IOU/A door has an interior pulling handle also that is installed at the factory.
Aluminium surface doors, IOU/A, and IPO/A, are designed to be compatible with aluminium windows. The balcony door glass height can be specified according to the height of the adjacent window. A full-glass balcony door is an option also.
