When it comes to thermal and acoustic insulating performance, our Novoferm ISO20 sectional doors are market-leading performers. The secret lies in the construction of the doors, which is a method that is exclusive to Novoferm. We’ve adopted a double-skinned sandwich approach to how we fabricate these doors. This construction allows for the insertion of a 20mm insulating rigid PUR foam core (heat insulation value K = 1.0 W/m²K).

The result is improved heat insulation, acoustic dampening, and quieter door operation when compared to single-skinned variants. At low temperatures, it’s possible for the sections of a door to not fit as closely as they should, especially if sub-standard seals are used. This can allow warm air to bleed out, lowering the temperature of the room. Our doors are equipped with flexible lip seals to prevent heat from escaping, and to keep out dust.

Sectional garage doors with 20 mm insulation made by Novoferm are standard supplied with a vertical tension spring system.

1. Interference-protected deflection pulley
The steel cables run vertically into the angular frame on interference-protected deflection pulleys mounted on ball bearings with U-shaped roller holders. This reduces the height requirement compared to a front-mounted torsion spring.

2. New cable mount
Together with the new steel cable holder, the newly designed cable mount with integrated door guide keeps the steel cables running smoothly in the angular frame without them touching the sections.

3. Integrated belt fastening
The newly designed moulded end piece contains an integrated fastener for the NovoPort® belt. The maintenance-free belt is fastened securely in the holder.

4. Multiple tension spring assemblies
The tension spring garage doors are equipped with sturdy multiple tension spring assemblies. The springs are adjusted at the top end of the assembly. The vertical tension springs require less installation depth and open up new possibilities when space is confined.

5. NovoPort® – unique & flexible
The NovoPort® operator system not only offers maximum convenience during operation, but also during installation. After all, the motor is not fixed to the ceiling like conventional operators, but simply integrated into the side garage door track – either on the left or the right depending on the structural conditions. Therefore no ceiling assembly is required.

6. Anti-pinch inside and out
The special design of the sections and hinges prevents pinching on the door leaf from the outset. Pinching is not a risk on the inside of Novoferm doors either.

7. Interference protection and cables channelled down the inside
The angular frames make it almost impossible to reach between the door leaf and the frame. Suspension cables arranged inside minimize the risk of injury and guarantee maximum operational reliability.
