Granite Door and Window Frames

Granite door and window frames, often called stone chaukhat, are a common and sensible choice in Rajasthan and across India. A wooden frame on a ground-floor bathroom door can swell, rot or be eaten by termites within a few years. A granite frame does none of these things. Fixed properly into the masonry, it stays straight and solid for the life of the building and gives openings a crisp, finished outline.

This article explains where granite frames work best, how they are designed and fixed, and the details that make the difference between a neat frame and a troublesome one.

Why choose granite frames

• Termite-proof and rot-proof. Ideal for bathrooms, kitchens, ground floors and any damp wall.
• Dimensionally stable. Granite does not warp or twist with seasons, so shutters keep closing smoothly.
• Low maintenance. No polishing, painting or varnishing every few years.
• Strong look. A dark granite outline around an opening gives a clean, architectural finish.

Granite frames are very popular for bathroom and toilet doors, kitchen and store doors, and window openings, especially external ones that face rain. Main doors are often still done in wood for a traditional look, sometimes with a granite sill below.

Choosing the granite

Black granites such as Telephone Black, Z Black and Black Pearl are the most common choice for frames because the dark outline contrasts well with light walls and floors. Lighter granites are also used where a softer, matching look is preferred, for example a pink or grey frame with a similar floor.

Pick frame pieces from one lot so all openings in the house match. Small white spots or veins that are acceptable on a floor can stand out on a narrow frame, so check pieces carefully.

Frame design and sizes

A granite frame has two vertical pieces (jambs), a top piece (head) and, for windows and some doors, a bottom piece (sill). The width of each piece is decided by the wall thickness and the shutter design.

Rebate for the shutter

The shutter needs a stop to close against. This is achieved either by fixing an additional strip of granite along the frame to form a step, or by shaping the frame. The shutter maker must confirm the shutter thickness before this detail is finalised.

Edge profiles

Exposed edges are usually rounded or moulded so they are comfortable to touch and less likely to chip. Corners where the head meets the jambs can be butted or miter-cut. Miter joints give a seamless look but need very accurate cutting.

Window sills and drip grooves

External window sills take rain directly. A granite sill should slope slightly outward so water runs away from the window. A drip groove is cut on the underside of the projecting edge, so water drips off instead of running back along the wall and staining the plaster below. This small groove saves years of damp patches.

Fixing granite frames in masonry

Granite frames are best fixed during brickwork, so they are locked into the wall as it rises.

1. Mark the exact opening sizes and positions from the drawing, including finished floor level for doors.
2. Set the jambs plumb with a spirit level and plumb bob, and brace them temporarily.
3. Build the masonry around them with mortar packing at the back, using ties or clamps where needed.
4. Fix the head piece level, with masonry or a lintel properly carrying the load above. The frame must not carry the wall.
5. Protect the polished faces during plastering and later work.

Frames can also be fixed into openings in finished walls, but squaring and packing take more care, and the plaster around the frame then has to be repaired neatly.

Hinges, locks and hardware

Hinges on granite frames are fixed by drilling the stone and using suitable anchors, or by fixing a wooden or metal sub-frame for the hardware. Lock strike positions also need drilling. Drill positions should be planned with the shutter maker, and holes must be kept back from the edge to avoid cracking the frame.

Mistakes that spoil granite frames

The most common problem we see is a frame that is not plumb, which makes the shutter swing open or shut on its own and leaves uneven gaps. Another is a door frame set without reference to the finished floor level, so the shutter either scrapes the new granite floor or leaves a large gap below. Frames that carry wall load because the lintel was skipped can crack across the head piece. Plaster splashed on polished faces and left to harden also leaves permanent dull patches. Careful marking, a proper lintel and protective tape or sheets during plastering avoid all of these problems at very little extra cost.

Granite frame checklist

• Opening sizes, wall thickness and shutter thickness confirmed.
• Granite variety and frame width agreed.
• Rebate or stop detail decided with the shutter maker.
• Edge profile and corner joint chosen.
• Sills sloped outward with drip grooves for external windows.
• Lintels in place so frames do not carry wall load.
• Hinge and lock positions planned before drilling.

Get your frames planned early

Granite door and window frames are a one-time investment that saves repairs for years. Since they are best fixed during masonry, it is worth involving your stone contractor early in construction.
