If you’re looking for a modern, no-fuss window, then uPVC casement windows are the right choice. Choose from A or A+ double-glazed uPVC casement window styles, or upgrade to triple-glazed. There are plenty of designs – or configurations as we call them – to choose from depending on where in the home you’re looking to replace or add a window.

Our uPVC casement window frames have trickle vents for ventilation and can be placed on the latch to reduce unwanted condensation. Looking for something different to a standard white gloss finish? Your chosen frames can be foil-coated with the colour of your choice and customised with handle and glass options.

uPVC casement windows are BFRC-certified and A-rated as standard in double glazing, or A+ in triple glazing.

Upgrading from pre-2002 uPVC double-glazing to A-rated windows from Anglian could save you £184.25 off your annual energy bills*. That's more than £1800 over 10 years.

New uPVC casement windows are one of the best options on the market to reduce heat loss. We fill the thin gap between our windows with an inert gas. These colourless, insulating gases have the added effect of helping to reduce sound through the glass of a window. The airtight double weather seal when closed reduces draughts too.

*Source Glass and Glazing Federation. A typical detached house has 23.7m2 of windows. Based on replacing uPVC double-glazed windows with a 12-14mm sealed unit and gas central heating with A-Rated thermally efficient windows.

We leave nothing to chance when it comes to the important task of ensuring that your home is as ‘safe as houses’. Our uPVC casement windows have a range of modern anti-burglar features as standard.

  • Multi-point locking systems engage at several points along the window frame. This helps to distribute the force of any attempted break-in and makes it much more difficult for intruders to force the window open.
  • Lockable handles that prevent the window from being opened from the outside come as standard. This provides an extra layer of security to prevent tampering or unauthorised entry.
  • Internal glazing means the glass is fitted from the inside of the frame during manufacture. This makes it more difficult for intruders to remove it from the outside.
  • Reinforced frames make them more resistant to impact and forced entry.
  • Multi-chambered uPVC construction with welded joints for added strength.
  • Where legally required, the window glass is laminated, making it shatter-resistant to provide extra protection against break-ins.

Our insurance-backed guarantees mean they remain valid until they run out. Not all window companies offer this, so be on the lookout. Under the terms of the guarantee, you are covered for the cost of a partial or complete repair of your windows.

  • 10-year guarantee on frames, parts and labour.
  • 15-year guarantee on the sealed glass unit. The sealed unit is covered in the event of a ‘blow out’, where condensation appears between the panes of glass.

Your Questions Answered by Us

Are uPVC casement windows expensive?

Do uPVC casement windows add value to my property?

While the value added by uPVC casement windows can depend on various factors, including the location and condition of the property, investing in high-quality windows can be a worthwhile investment that can improve the overall value of your home.

What are uPVC casement windows?

uPVC casement windows are a type of window that has a hinged sash that swings outward from the frame. They are made of uPVC, which stands for unplasticized polyvinyl chloride, a durable and low-maintenance material that is commonly used in window frames. Casement windows are popular for their versatility and energy efficiency. They can be opened to allow the greatest airflow and natural light into a room, and their tight seal when closed helps to prevent drafts and improve insulation.

Why are uPVC casement windows so popular?

They are known for their energy efficiency and can help to reduce heating and cooling costs by providing good insulation and reducing drafts. uPVC is a low-maintenance material that is easy to clean and does not need painting or sealing. This makes uPVC casement windows a convenient option for homeowners who want a hassle-free window solution.
