Envisage Flush UPVC Windows

5 Star use argon gas filled units in their UPVC Windows.


Poor-quality double-glazing units, in UPVC Windows, are filled with fresh air, conducting cold air between the panes, costing you money. Argon is an inert gas, which is pumped into the 20mm void between 5 Star’s standard double glazing units. In addition, it does not conduct the cold air and significantly reduces the build-up of condensation.

20 Year Guarantee – that’s a lot of Peace of Mind.


At 5 Star, our 20-year guarantee is probably the longest in the industry and is backed by a further insurance guarantee for 10 years, the longest we can buy for you from the CPA (The Consumer Protection Association).. That’s because we know that our UPVC windows are built to the highest standards and will last and last. The materials and components used to create our UPVC windows are absolutely second to none.


  • Equal sightlines for a balanced look, or varying panes and openings as you choose.
  • Created by the sash sitting flat and flush with the surrounding frame.
  • Smooth weld technology gives you an almost invisible corner joint option.
  • The window opens inwards so you can clean the glass without leaning out, whilst the tilt option provides ventilation.
  • Sliding sash options for the horn.

UPVC Sash Windows

Aluminium windows have four significant differences to UPVC windows and are usually more expensive.

Aluminium being stronger is generally thinner than UPVC giving you more view and less frame. Aluminium comes in almost any RAL colour, it hardly expands or contracts and it will last many decades.

Both products have significantly developed over the years and now the choice really does come down to personal preference.
