The Novoferm ISO 45 Large Rib is one of our most popular insulated sectional doors. The large rib gives the door a contemporary feel much favoured by our customers. Manufactured near Dusseldorf in Germany, Novoferm sectional garage doors are class leaders in quality and design.
The construction of the Novoferm ISO 45 Large Rib
A double skin of hot dipped galvanised steel encloses a rigid foam core of CFC free elastic PUR. This construction gives a strong, sound and heat insulating section. These sections, usually four but more for higher doors, move on wheels in vertical and horizontal tracks. The horizontal tracks are held in an angle frame. This frame comes as standard in traffic white but if a colour other than traffic white is chosen for the door then colour matched profiles are available for the door frames. The door also has a header. the header is always colour matched to the door. The Novoferm ISO 45 large rib has torsion springs. The springs, mounted on a shaft, are fixed above the door opening or, with the low headroom option, at the back of the horizontal tracks. The spring shaft is attached to the door leaf by cable drums and cables which have a cable spring break safety device fitted. All the steel parts of the Novoferm ISO 45 large rib are hot dip galvanised. The feet of the frame legs are stainless steel. This prevents corrosion at this vunerable point where the the door frame cones in contact with the floor and may sit in water. Rubber seals exclude draughts. As well as a frost resistant floor seal there are lipped seals on the sides and header. There are also rubber seals between each section. This door has a class leading insulation values of K = 0.5 W/m2 K. The Novoferm ISO 45 large rib can be automated using either the Novoferm 553 or the Novoferm Novoport operators. A manual option can also be specified.
