An exclusive design

A high level of robustness

INSUPLUS, the 10 year warranty  warranty insulated door represent the top standard for mechanical resistance: the steel tubular frame exclusive to Doortal, the 1.5 mm thick leaf with internal reinforcements as well as strong hinges with stainless steel ball bearings grade 14 according to EN 1935 standard.

High degree of usability

DOORTAL’s insulated door design offers comfortable use, with no sharp edges on the leaf and all seals securely fixed. The styling is clean, with no visible welding points.

A high level of performance

The use of insulating materials combined with steel optimizes thermal breaks whilst maintaining robustness.

Thermal door

In context of sustainable development and environment awareness, the INSUPLUS range is composed of three types of insulated doors that score high ratings:

– INSUPLUS 2.1: Ud value of 2.1 W/m².K
– INSUPLUS 1.5: Ud value from 1.8 to 1.4 W/m².K
– INSUPLUS 1.2: Ud value from 1.5 to 1.2 W/m².K

The lower the figure, the higher the performance (which means the lower the energy loss). These ratings have been achieved by carefully selected insulated materials to create thermal breaks.

Acoustic and Air, Water and Wind resistance ratings
