Recyclable and

Aluminium can be recycled almost indefinitely with no reduction in the quality of the metal. It does not deteriorate over time, and recycling it has minimal environmental impact. So, unlikely as it may first appear, aluminium windows are a good choice for eco-builds and passivhaus projects.

A word about our glass

Today’s double glazing is not just about letting light in. Innovations in glass manufacture allows modern double glazing to be extremely energy efficient, controlling how much heat is let is from sunlight, and minimising heat loss from inside your home. This is achieved by using thermally insulating glass coatings, creating Low Emissivity Glass or Low E glass.

Our product of choice is Saint Gobain’s Planitherm Total+ range; an A-Rated unit as standard. Planitherm Total+ low-e glass is developed and made in the UK, and was specifically designed to achieve the best Window Energy Ratings (WERs) possible.

Planitherm Total+ :

  • Is energy efficient, balancing thermal insulation and maximising solar gain
  • Reduces heat loss in winter, eliminating cold areas around windows
  • Reduces condensation on the inner pane of glass
