Here at Novoferm, we manufacture our ISO45 sectional doors with a double-skinned sandwich construction. Inside, there’s an insulating rigid PUR foam core that provides maximum heat-insulating and soundproofing qualities. With this build-quality, customers will also note that these doors feature a quieter operation when compared to single-skinned options.

Plus, further heat loss and sound bleed are prevented by the addition of flexible lip seals which maintain a tight seal, even in low temperatures. These seals also help to keep dust out too keeping the internal environment neat and tidy. What sets our ISO45 sectional doors apart from our ISO20 option is the addition of a 45mm rigid PUR foam core. The acoustic and thermal performance of this core is outstanding (heat insulation value K = 0.5 W/m²K).


If your intention is to add your own personal touch, you’ll be pleased to hear that our ISO45 option is available in any of the following five patterns. There are also numerous top-coated surfaces available too, as well as a wide selection of colours from the Novoferm range.

When you invest in our ISO45 sectional garage doors, you’ll have the option to upgrade your doors with vertical tension spring technology or sturdy torsion springs. Our ISO45 doors (up to 3000 x 2750 mm (WxH))* can be equipped with torsion springs. These springs feature a maintenance-free spring fracture safety device which is certified to EN 12604. This service can be provided at an extra cost.

For all larger versions of our ISO45 doors, torsion springs are equipped, ensuring that these doors remain in place and can be pushed back up, even if a spring fails. 

This applies to woodgrain finish models only. The size restriction for smooth surface models is set lower at 3000 x 2500 mm*
