Double Glazed uPVC Casement Windows Made for Hayes Homes
uPVC casement windows are the most popular window style in the UK, and the reason is simple. Each sash is hinged at the side or the top and opens outward, then presses tightly against the frame seals when locked, which keeps draughts out and heat in. Our uPVC casement windows are virtually maintenance free, so they will never peel, flake, fade, rust or rot.
Eurothermal's double and triple glazed casement windows are among the highest performing windows on the market, with industry leading U-values for exceptional energy efficiency. Every window is made to measure and fitted by our own FENSA certified team, so your new windows arrive with a full product and installation guarantee and a FENSA certificate. Whether you are replacing one window or the whole house, we cover Hayes, Hillingdon, Uxbridge, Southall and Yeading.

Casement Window Types and Opening Styles
Casement windows do not all open the same way. The hinge position changes how a window ventilates, how it cleans and whether it can work as a fire escape, so we recommend the right mix room by room during your technical survey.
- Side hung casement windows hinge at the edge and swing outward like a door, the most versatile style we fit
- Top hung casement windows hinge at the top and open from the bottom, ideal above kitchen worktops and baths
- Fixed light panels sit beside opening sashes to bring in extra daylight without extra moving parts
- Mixed casement windows combine fixed lights with side and top hung sashes in one frame for wide openings
- Georgian and cottage bar patterns can be added to any casement style for a traditional look
- Bay and shaped casement windows suit period fronted rooms that want extra space and light

Casement Windows for Fire Escape and Child Safety
Bedroom windows above ground floor usually have to provide a way out in a fire, and the style you choose decides whether that is possible. A side hung casement is normally the best candidate because it opens wide and clear. A top hung window usually cannot do the job, so we plan bedroom layouts with this in mind before anything is ordered.
- Side hung casements fitted with fire escape hinges open close to 90 degrees to leave a clear exit
- Top hung sashes are generally unsuitable as escape windows, so we steer bedrooms toward side hung styles
- Easy clean hinges let you reach the outer glass from inside, which helps on upstairs windows
- Child safety restrictors limit how far a sash opens while still letting fresh air in
- Minimum clear opening size and sill height rules apply, and we measure each opening to confirm compliance

Double and Triple Glazed Casement Windows
The right glazing depends on the room, not just the window. Double glazing is enough for most rooms, while triple glazing earns its place on cold north facing walls and on homes near busy roads, railways or flight paths, which is a reality in parts of Hayes, Southall and Hillingdon.
- Up to A++ rated double and triple glazing delivers low U-values and lower heating bills
- Triple glazed casement windows add a third pane for stronger sound reduction and warmth
- Inert gas filled sealed units reduce heat loss through the glass itself
- Trickle vents control condensation in kitchens and bathrooms without opening the window
- Laminated glass options add security and sound reduction to ground floor and street facing windows

Period Style Casement Windows
Replacing old timber casements does not mean losing the character of your home. Georgian bars, woodgrain finishes and carefully matched proportions let a modern uPVC casement blend into a Victorian or Edwardian frontage.
- Georgian and astragal bar patterns recreate the glazing layout of original period windows
- Woodgrain foils give the warmth of timber without sanding, painting or rot
- Frame depth can be matched to your original window to avoid cutting back plaster during fitting
- For the flattest timber look finish, see our uPVC flush casement windows with Smoothweld joints

Frequently Asked Questions
Ask Us a QuestionWhat are the different types of casement window?
The main types are side hung casements, top hung casements and fixed lights, and they can be combined in one frame. Side hung sashes swing outward like a door, top hung sashes open from the bottom, and fixed lights do not open at all and simply add daylight. We recommend the mix for each room during your survey.
Can a casement window be used as a fire escape?
Yes, a side hung casement fitted with fire escape hinges can serve as an escape window if the opening is large enough. These hinges let the sash open close to 90 degrees, and Building Regulations set a minimum clear opening size and sill height. Top hung windows generally cannot be used as escape windows, so we check every bedroom on survey.
How much do uPVC casement windows cost?
Independent UK price guides put a standard uPVC casement at roughly £350 to £950 per window fitted, depending on size, colour and glazing. Coloured and woodgrain finishes add to the price, and triple glazing costs more than double. For a typical three bedroom house in white uPVC the guides suggest about £4,000 to £8,000. These are national guide figures, not a Eurothermal quote, so book a free survey for an exact price.
Are casement windows more draught proof than sash windows?
Casement windows are usually more airtight because the sash presses against compression seals when it is locked. Sliding sash windows rely on brush seals along the runners, which can let in slightly more air, although a modern uPVC sash still performs well. Both are available from Eurothermal.
What is the difference between casement and tilt and turn windows?
A casement window hinges at the side or top and opens outward, while a tilt and turn window opens inward, either like a door or tilted at the top for ventilation. Casements suit most homes and offer the widest style choice. Tilt and turn windows suit upper floors and flats where cleaning and outward opening are awkward.
Do I need a FENSA certificate for new windows?
Yes, replacement windows in England must comply with Building Regulations, and a FENSA registered installer can certify the work and issue a certificate. You will usually need this certificate when you sell your home. Eurothermal is FENSA certified, so your certificate is included with a full product and installation guarantee.
Are triple glazed casement windows worth it?
Triple glazing is worth considering on cold north facing walls and on homes near busy roads, railways or flight paths, where the extra pane improves warmth and sound reduction. For most other rooms, A rated double glazing is enough and costs less. We talk through the options room by room at your survey.
How long do uPVC casement windows last?
Well made and properly installed uPVC casement windows commonly last 20 to 30 years. Because the frames cannot rot, rust or need repainting, the main upkeep is cleaning and an occasional check of the seals and hinges.
