Lower energy consumption and save costs – through thermal separation with insulbar®

Windows, doors and facades are the parts of any building envelope which give off most heat to the surrounding atmosphere. The less effective the insulation, the higher the loss of heat in the form of thermal transmission, heat convection and heat radiation.

Plastic insulating profiles reduce loss of heat

Windows, doors and facade systems made of aluminium, with its high thermal conductivity of λ = 160 W/(m⋅K), are particularly susceptible to thermal and energy losses. In order to reduce the thermal transmission of these systems and to achieve a more favourable thermal transmission coefficient (U value), it is necessary to insulate the window frames and thermally separate their outer and inner shells from each other. Plastic insulating bars from Ensinger are the ideal way of doing this.

Low thermal conductivity for excellent Uf values

insulbar® insulating bars are characterized by extremely low thermal conductivity, and so enable excellent Uf values for frames and assemblies, reduce loss of heat and so contribute towards saving energy reducing heating and air conditioning costs.

Aluminium window without thermal separation
High loss of heat through the frame of an aluminium window without thermal separation.
Thermal separation in the aluminium frame with insulbar profiles
insulbar® polyamide profiles ensure thermal separation in the aluminium frame and reduce loss of heat.
Diagram showing savings relative to insulation depth
The savings are determined by the insulating depth: The bigger the insulbar® profiles, the more energy and costs can be saved.
Diagram showing scope for savings relative to the thermal transmission coefficient
The lower the thermal transmission coefficient, the greater the scope for savings: Heating and air conditioning costs depend on the Uf value of the window frame.

Thermal separation with insulbar®. The benefits at a glance:

  • Compliance with statutory energy saving requirements
  • Lower energy consumption and carbon emissions
  • Saving of heating and air conditioning costs
  • Improved room climate and optimum temperature distribution
  • Fewer draughts and no chill sensation close to windows
  • Prevention of condensation and mould formation
