insulbar® insulating bars on shiny surface
In perfect form For the required function

The right geometry for every application

To cover the wide range of different window, door and facade systems, Ensinger offers insulating bars in a variety of profile shapes and geometries, and for all popular insulation depths. insulbar® insulating profiles are fitted with special functional elements and come in different wall thicknesses and foot geometries to fit specific requirements.

Straight, offset and hollow chamber profiles in plastic - with wide-ranging functions

Starting from the three profile types – straight, offset and hollow chamber – there is an enormous selection of application-specific profiles available with different function zones: For instance insulating profiles with hook, groove or arrow to hold the gasket as well as insulating bars with nose or hollow chamber as a stopper for the gasket. Variants with screw channel or flag which bring about extremely low loss of heat are also available.

Matching sizes and wall thicknesses for every system

Standard insulbar® insulating profiles are currently available for insulating depths of between 10 mm and 54 mm in different wall thicknesses. In order to guarantee the stability of bars / frame constructions, it is not admissible to drop below a defined wall thickness.

Foot geometries with narrow tolerances to match your aluminium chamber

The foot of the insulating bar forms the connection to the retaining chamber of the aluminium profile in the frame construction. Optimum coordination of the foot geometry to the aluminium chamber ensures high shearing strength and transverse tensile strength, as well as shear stiffness of the assembly. For this, different foot geometries with very close tolerance ranges can be implemented.

Recommended aluminium chamber variants

For insulbar® insulating profiles, Ensinger recommends two different aluminium cavities depending on the application. The most commonly used variant is the cavity with short hammer. In exceptional circumstances – for instance in case of obstacles which make the hammer difficult to access for the roll-on wheel – Ensinger offers an alternative with a long hammer.

The Coex sealing wire – a reliable moisture barrier

The Coex sealing wire integrated in the foot – an Ensinger invention – is used to create a perfect seal of the assembled system. As well as ensuring a reliable moisture barrier, it also provides an additional safeguard against displacement of the assembly. The polyamide core of the Coex wire is sheathed in hot-melt glue which melts and is consequently activated by the effect of heat during coating. insulbar® insulating profiles are supplied today as standard with Coex wire.
