aluminium windows VS others

Aluminium windows have many advantages compared to UPVC windows or wooden windows. All materials have their own properties, their strengths and weaknesses differ in detail. In contrast, aluminium has by far the best stability and the longest service life. On the other hand, wood and uPVC impress with their low thermal conductivity and therefore have very good thermal properties. So that aluminium windows also guarantee excellent thermal protection, we equip them with appropriate insulation systems, seals and glazing.

More advantages of aluminium windows:

  • Extremely durable and low maintenance
  • High resistance to mechanical deformation
  • Excellent protection against theft
  • Various colour adjustment options
  • Modern and timeless design options
  • High energy efficiency achieved by combining with thermal insulation materials, ensuring good thermal insulation values

One great advantage of aluminium over other metals is that it does not rust. This results in weather resistance that cannot be achieved with other materials. Rain and moisture do not damage aluminium windows. It is also resistant to sunlight. This applies to ageing processes caused by UV radiation as well as the effects of summer heat.
