Do you get condensation in aluminium windows?

Black aluminium casement window

Condensation is a relatively common problem in both period properties and newer homes, with 1 in 5 UK households affected. So it’s no surprise that we’re often asked, ‘Do you get condensation in aluminium windows?’

Simple answer is yes you can get condensation in aluminium windows. But there is slightly less chance with aluminium windows due to the material and u-values. As the most abundant metal on the planet, Aluminium has come a long way as an industrial construction material. Modern technology has pushed aluminium to the forefront of the replacement windows and doors industry, making it the number one choice for residential property renovations. Incredibly strong, lightweight, modern and low maintenance, aluminium is very environmentally-friendly too. So, can you prevent condensation with aluminium windows? Let us explain!


Energy efficient glazing not only helps reduce our carbon footprint and energy bills, it can also reduce condensation build up on the inside of your windows. U-Values measures how efficiently heat is transferred by the entire window, either into or out of the building. The lower the U-Value number, the better the window will retain heat inside your home on a cold day. Our range of industry leading aluminium windows feature advanced thermal efficient glass to ensure minimum heat loss. Furthermore, our RE-AL Aluminium casement windows are fitted with energy efficient glass achieving a window energy ‘A’ rating when used in conjunction with 28mm double or 36mm triple glazed units. Therefore, the chance of condensation build-up is considerably reduced due to the quality and thermal efficiency of glass that we provide.

Prevent Condensation

Replacement aluminium windows from Chase Windows will be much more airtight than your original frames. So there is a chance that condensation may build up in your home due to reduced ventilation. If this is the case, it’s time to address your ventilation options.

  • Open windows regularly and let the vapour out.
  • Reconsider drying clothes inside; g. on radiators or on a clothes horse.
  • Trickle vents allow a controlled amount of ventilation to reduce condensation build up. For example, our Origin range have the option for a frame extension and trickle vent or a trickle vent to the sash.
  • Use extractor fans proactively in kitchens and bathrooms.
  • A dehumidifier will remove excess moisture from the atmosphere.
  • Check your gutters; if they’re leaking this could be causing condensation.
  • Check your window seals. If there’s condensation in between the panes of glass, it’s most likely that the seal is broken and needs replacing.
  • If all else fails, you may well have a damp problem within the structure of your home, e.g. rising damp or penetrating damp. This may require adding extra insulation or a damp proofing course.
