Overview

What is a casement window?

uPVC casement windows are usually the practical starting point for Romford and Essex homes that need reliable ventilation, warmer rooms, secure locking, and sensible value across several openings. The important detail is not just the frame system; it is how each bedroom, bathroom, kitchen, bay, landing, and side window should open. We survey opener direction, fire-escape hinge needs, trickle vents, obscure glass, safety glass, colour, bar layout, and whether a standard casement, flush sash, sliding sash, or aluminium casement is the better fit for each elevation.

10-year profile guarantee. No warping, splitting, or discolouration

£7,500 break-in protection promise

Stainless steel friction stays tested to 20,000 cycles

Configure Your Casement

Plan your casement windows room by room

Casement windows are the practical default for most Essex homes, but the right window is decided room by room: which sashes open, how the glass is specified, and how the panes are barred. These are the choices we work through before a survey.

Made to measure

Choose which sashes open, and how

A casement window is built up from fixed and opening lights. The mix is planned around how each room is used: ventilation, cleaning access, and whether a window needs to double as a fire escape.

Fixed light

Fixed light

A pane that does not open, used to keep the cost down and maximise glass and daylight where ventilation is not needed. Usually paired alongside opening sashes in the same frame.

  • Lowest cost per light
  • Maximum glass and daylight
  • Paired with openers elsewhere in the frame
Side-hung opener

Side-hung opener

The standard opening casement, hinged at the side on a friction stay so it holds at any angle without slamming. The everyday choice for living rooms, kitchens, and bedrooms.

  • Hinged at the side
  • Friction stay holds it at any angle
  • The everyday opener for most rooms
Top-hung opener

Top-hung opener

Hinged at the top so the sash opens outward and upward. Good for secure background ventilation and for an opener set above a fixed light or over a kitchen worktop.

  • Opens outward and upward
  • Works well over kitchen worktops
  • Secure background airflow
Fire-escape egress

Fire-escape egress

An egress or easy-clean hinge lets the sash swing wide enough to meet escape requirements, specified for bedrooms and habitable rooms where a window is the means of escape. The same hinge gives access to clean the outer glass from inside.

  • Wider opening for safe escape
  • Specified for bedrooms and habitable rooms
  • Easy-clean access to the outer glass

Opener direction, fire-escape lights, and trickle vents for background ventilation (Building Regulations Part F) are confirmed room by room at survey.

Glass and bar detailing to suit the room and the elevation

Once the openers are set, the glass and bar choices decide how the window performs and how it reads from the street.

Double or triple glazing

Double or triple glazing

A+ rated double glazing as standard, with optional triple glazing for north-facing rooms and exposed elevations, bringing U-values down to 0.9 W/m2K.

  • A+ rated double glazing as standard
  • Triple glazing down to 0.9 W/m2K
  • Warmer north-facing and exposed rooms
Obscure & privacy glass

Obscure & privacy glass

Obscure glass for bathrooms, en-suites, and ground-floor rooms overlooked by a path or neighbour, in a range of patterns and obscurity levels, with toughened safety glass where the location requires it.

  • Bathrooms, en-suites, and overlooked rooms
  • Range of patterns and obscurity levels
  • Toughened safety glass where required
Georgian & astragal bars

Georgian & astragal bars

Georgian bars within the sealed unit or surface-applied astragal bars recreate period pane detailing, matched to neighbouring windows or a conservation streetscape.

  • Internal Georgian or applied astragal bars
  • Matched to neighbouring windows
  • Period and conservation friendly
Slim sightlines

Slim sightlines

Left bar-free, the 70mm frame keeps a clean modern sightline with more visible glass and an uncluttered look, popular on contemporary and rear elevations.

  • Clean modern look
  • More daylight, less frame
  • Anthracite and dark foils available

Windows that work for everyone in the home

Every household uses its windows differently. Where someone in the home has limited reach, mobility, or grip, we adjust the window so it stays easy and safe to use. We will always plan the specification around what a customer needs.

Handle height and position set to suit reach from a chair, a bed, or standing

Lighter-action openers and easy-turn handles where grip or strength is limited

Friction-stay hinges that open with a light push and hold at any angle

Egress and easy-clean hinges so a window can double as a safe means of escape

Opening restrictors to limit how far a sash travels where safety needs it

Obscure and laminated safety glass specified room by room

If a household has a specific need, we plan the window around it at survey

Mention any accessibility needs when we survey and we will adapt the specification wherever we can.

After installation

Looking after your casement windows

uPVC casements are low maintenance by design. A little routine care keeps them opening cleanly and looking new for years.

  • Hinges and locks are adjusted at handover so every sash opens, closes, and locks cleanly
  • An occasional wipe of the seals and a drop of oil on the hinges keeps the action smooth
  • Frames need no painting or sealing, just a wipe down with warm soapy water
  • The drainage slots along the bottom of the frame stay clear with the same routine clean
  • Backed by the Cii 10-year guarantee with Assure certification where applicable

Product fit

uPVC casements for room-by-room Romford replacements

uPVC casement windows are usually the right starting point when a Romford or Essex home needs reliable ventilation, strong thermal performance, straightforward cleaning, and sensible value across several openings. On survey we look at each room separately because bedrooms, bathrooms, kitchens, bay windows, landings, and front elevations often need different opener layouts even when the frame system is the same.

Best fit for

  • Full-house uPVC window replacements where consistency and value matter
  • Bedrooms and living rooms that need controlled outward-opening ventilation
  • Homes where escape hinges, trickle ventilation, or obscure glass need room-by-room planning

Consider another option when

  • The front elevation needs a more traditional flush or sash-style frame line
  • A slimmer aluminium frame would make a visible difference on larger openings
  • The room needs inward opening for cleaning or secure ventilation

Compare window styles

Which window style is right for the opening?

Casement is the practical default for most Essex homes. Here is how it compares with the other styles we supply, so you can see where each one earns its place.

CasementYou are here
Most replacements and full-house upgrades. The practical default: secure, cost-effective, and available in every colour, glazing, and bar option.
Flush sash
Period homes and visible elevations. The sash sits flush with the frame for a flatter, timber-look finish that suits conservation areas.
Sliding sash
Victorian, Edwardian, and bay-fronted homes. Vertical sliding sashes that keep the authentic look of an original period frontage.
Sash horn
Period character without a full sliding sash. Casement convenience with traditional run-through horn detailing for character streets.
Tilt and turn
Cleaning access and secure ventilation. Tilts inward for airflow and turns fully inward for easy cleaning, ideal for upper floors and flats.
Aluminium casement
Slim sightlines and modern elevations. Slimmer powder-coated frames for larger openings and contemporary or dark-framed looks.

Optional Upgrade

Integral blinds for privacy without bulky window dressing

On the right rooms, integral blinds can give casement windows a modern, low-maintenance finish. They are most useful where privacy and light control matter but curtains or exposed blinds would make the reveal feel crowded.

Kitchen window with integral blinds sealed inside the glazed units

Clean window reveal

A between-glass blind option for selected rooms rather than every opening by default.

Useful on casements when

  • Bedrooms, bathrooms, or street-facing rooms need privacy
  • The room has a modern finish and a cleaner reveal is preferred
  • Exposed blinds would collect dust or sit awkwardly near handles

Blind types we can discuss

Magnetic integral blinds

A slim magnetic slider raises, lowers, and tilts the blind inside the sealed glass unit.

Electric integral blinds

Remote operation suits larger panes, harder-to-reach glass, and cleaner contemporary rooms.

What we check

  • Glass unit size and cavity depth
  • Handle position, reveal depth, and room layout
  • Whether magnetic or electric operation is worth pricing

We only recommend this where the unit size, opener layout, and room use make the upgrade worthwhile.

How It Works

From Survey to Sign-off

Step 1

Survey & room-by-room check

We measure every opening and check the lintel, sill, and reveal, then plan each window room by room: opener direction, which rooms need a fire-escape egress sash, where trickle vents are required for ventilation, and where obscure or safety glass is needed.

Step 2

Made to measure

Each casement is built to the measured size on the 70mm multi-chamber profile, with the opener layout, A+ double or triple glazing, any Georgian or astragal bars, the colour foil inside and out, and the shootbolt locking all locked together before manufacture.

Step 3

Install & sign-off

Our Cii team fits and seals each frame, adjusts every sash and the locking so it opens and closes cleanly, fits trickle vents where Building Regulations require them, and hands over with the Cii 10-year guarantee and Assure certification.

Outstanding from start to finish. The casement windows are a perfect fit and the energy difference is already noticeable. The lads were tidy, efficient, and clearly knew their trade.

Replaced all 12 windows across our Victorian terrace. Every window fits perfectly, the sightlines are great, and the house is noticeably warmer. Superb job.
