insulbar LO: lambda-optimised insulating profile for metal frames

At BAU 2017 Ensinger is presenting a new, highly insulating profile for windows, doors and facades. With a lambda value of just 0.18 W/m·K, it permits a better Uf value when retaining the same frame installation depth, or a smaller installation depth with the same Uf value.

Large areas of glass, slim frames, high energy efficiency: these features, desired by building owners and architects, can be achieved particularly with aluminium frames – assuming there is efficient thermal separation. Ensinger, inventor of insulating bars between outer and inner shells of metal frames, is now going one step further.

"We have succeeded in lowering the thermal conduction capacity of the insulating profile by a further 40 percent", explains Jan Danger, head of the building products division at Ensinger, the plastics specialist. "With the lambda-optimized insulbar LO, it is possible to produce even more delicate frames that meet the highest standards when it comes to the insulating properties."

With a thermal conduction coefficient (λ) of just 0.18 W/m·K, the new insulating profile LO has the usual smooth, compact exterior. The key to its even greater insulating efficiency is its porous core: the glass fiber reinforced polymer blend (PA 66 and PPE) contains microscopically small, closed cavities.

This special structure is patented by Ensinger. The insulating properties are improved and the insulating bar is also lighter than a solid profile. The requirements of DIN EN 14024 regarding transverse tensile strength and shear strength are fulfilled (test report by the ift Rosenheim).

insulbar LO is precisely molded and available in the conventional geometries as well as in individual designs and styles. The variant LEF for example, assisted by a Low-e film on the flags of the profile, reduces energy losses through heat radiation to a minimum. Capable of being processed in the normal way, insulbar LO also permits anodization and powder coating in the finished assembly.

About insulbar

Ensinger GmbH is among the world's leading developers and producers of insulating profiles for window, door and facade construction. The profiles marketed under the brand name insulbar create a thermal separation between the inside and outside shells of metal frames. Insulation systems using insulbar profiles achieve optimum values in terms of energy savings and cutting the cost of heating and cooling. At the same time, insulbar profiles comply with the most stringent quality standards in every respect. They have been in successful operation around the world for 40 years.

At BAU 2017 Ensinger is presenting a new insulating profile for metal frames of windows, doors and facades: insulbar LO (Lambda Optimized).
Smooth exterior, porous interior, the new insulating profile from Ensinger permits particularly efficient thermal insulation in the metal frame.
1) Reduced Installation depth. Compared with the conventional insulating profile (λ = 0.3 W/m·K), insulbar LO's thermal conduction coefficient is 40 percent lower (λ = 0.18 W/m·K). Ensinger thereby enables window systems with improved Uf values or reduced installation depths.
Low lambda, large benefits: Window systems with insulbar LO from Ensinger feature high insulation efficiency and can therefore have a smaller installation depth.
