Anatomy

Inside a Mason casement

Casement is the most engineered window shape in the Mason catalogue — six design decisions decide how it swings, seals, and stays put for the next thirty years.

White uPVC French doors with Georgian bars and brass handles
  • 01

    Multi-chambered uPVC frame

    Three-to-five air chambers inside the frame insulate thermally and reinforce the leaf — important because casement carries its own weight on a hinge edge.

  • 02

    Heavy-duty friction hinges

    Stainless steel hinges sized for the leaf weight. They hold the leaf in any partial-open position without sagging, even after years of daily use.

  • 03

    Four-sided EPDM gasket

    Continuous rubber seal on all four edges of the leaf. When the multi-point lock pulls in, the seal compresses uniformly — that's why casement is the tightest window type.

  • 04

    Multi-point hook lock

    The handle drives four-to-six hooks into the frame at once — top, bottom, and centre. Pulls the gasket tight and adds genuine forced-entry resistance.

  • 05

    Integrated drip rail

    A small profile at the bottom of the leaf channels rainwater outward over the sill instead of pooling. Essential during Vizag monsoons.

  • 06

    Optional tilt-turn handle

    The upgrade. Two-position handle that lets the leaf either swing open like a door or tilt inward 10cm from the top for trickle ventilation.

Configurations

Four ways a leaf can open

Mason fabricates casement in four configurations — pick by how big the opening is, how you want it to ventilate, and whether you want premium European hardware.

Single leaf

One side-hinged leaf in a frame. Cleanest look. Up to 900mm wide, 1500mm tall. The default casement.

From ₹450 / sq.ft

Double leaf

Two leaves meeting in the middle, both opening outward. The classic French-door look. Up to 1800mm wide.

From ₹650 / sq.ft

Top-hung

Hinged at the top, opens outward from the bottom. Perfect for high windows and bathrooms — rain stays out even when open.

From ₹500 / sq.ft

Tilt-turn

The premium upgrade. Two-position handle — swing fully open or tilt the top inward for secure trickle ventilation.

From ₹750 / sq.ft
Glass options

The glass changes everything

Casement carries the same glass options as our other windows — but because the seal is so tight, premium glass actually performs to its rated spec instead of being undermined by air gaps.

Clear

Maximum light. Default for bedrooms and living rooms on non-west facades.

5mm · 6mm

Tinted

Green, grey or bronze. Pairs especially well with casement because the seal stops heat the glass blocks.

5mm · 6mm · 8mm

Frosted

Bathrooms and ground-floor street-facing rooms. Standard upgrade for top-hung bathroom windows.

5mm · 6mm

Toughened

4–5× stronger than annealed. Mandatory above the 4th floor and on full-height French doors.

5mm or higher
Where it shines

Best rooms for casement

Casement wins where you need an airtight seal, full ventilation when open, and the visual line of a single uninterrupted glass plane.

Bedrooms

Tilt-turn especially — open fully for cross-ventilation, or tilt inward at night for secure trickle airflow.

Bathrooms

Top-hung casement keeps rain out even when open. Frosted glass for privacy. Mandatory for high-humidity rooms.

Balcony French doors

Double-leaf full-height casement onto a balcony. The premium choice — opens the room completely to outside.

Facades that face traffic

The 4-gasket seal cuts noise better than any other window type. The street outside disappears the moment you close it.

Casement vs Sliding

Pick the right mechanism

Casement seals better and ventilates more. Sliding is cheaper and needs no swing space. Both are excellent — this table will help you choose.

Why Mason

Three reasons casement holds true with us

Casement windows fail in three ways — sagging leaves, leaky seals, and locks that get stiff. Mason engineers around all three.

01

Hardware sized to the leaf

Every casement leaf is spec'd with hinges rated for its actual weight. A small leaf gets light-duty hinges; a French-door leaf gets heavy-duty. No undersized hardware that fails after year three.

02

QC checklist before it ships

Every casement leaf goes through a rigorous workshop check — swing smoothness, lock alignment, gasket compression, drip-rail clearance. Catches issues before they reach your wall.

03

Honest sizing advice

If your opening is too wide for a single leaf, we'll tell you and propose a double — even if it's a smaller order. We'd rather not install something that will sag.

FAQ

About casement, answered

Common questions homeowners ask before ordering casement uPVC. If yours isn't here, ping us — we answer in under a day.

What's the difference between casement and French doors?

Mechanically they're identical — both are side-hinged uPVC frames that swing open. The terms differ by size and use: casement windows sit above sill level for ventilation; French doors run floor-to-ceiling and act as a doorway, typically for balconies and gardens.

Is tilt-turn worth the extra cost?

For bedrooms — yes. The tilt position lets you ventilate at night without leaving the window unlocked. For other rooms it's a nice-to-have, not essential. Most clients pick tilt-turn for one or two bedrooms and standard casement for the rest.

Are casement windows good for Indian monsoons?

Yes — casement is the most weather-tight window type we make. The four EPDM gaskets plus multi-point lock compress into a continuous seal. Coupled with the integrated drip rail, casement handles Vizag monsoons and Hyderabad dust storms better than sliding.

How wide can a casement leaf be?

A single casement leaf is fabricated up to about 900mm wide and 1500mm tall. Wider openings use double-leaf or are paired with fixed glass panels. French doors typically run as twin leaves of 700–800mm each.

Do casement windows need swing-space inside?

Standard casement swings outward, so no indoor swing space is needed. Tilt-turn can also swing inward — useful for upper floors where outward swing would interfere with awnings or facade detail.
