The IDEAL 4000 series is the basic proposal in the field of aluplast external door solutions. Thanks to multi-chamber housing with a depth of 70 mm and the use of a door threshold with a thermal insulation spacer, they have very good thermal insulation parameters. The use of steel reinforcements with large cross-sections and the use of weldable corner connectors guarantees appropriate static and strength parameters.
As part of the system solution, there is a low door sill with a height of 20 mm, which corresponds to the requirements for buildings without architectural barriers and enables easy entry and exit.

• Mounting depth 70mm
• Coefficient of permeability U_f  equal to 1.5 W/m²K
• a circumferential inner gasket and an additional outer gasket for exceptional thermal insulation
• threshold with thermal breakdown
• weldable corner connectors guarantee appropriate static and strength parameters
• The use of specialized fittings guarantees excellent anti-burglary protection
