Parts of a window

Parts of a window

You will certainly have windows in your property but there are lots of types of window styles such as, a sash window where the top and bottom windows slide up and down, or a casement window, this type of window opens outwards like a door and is very common in new houses.

Windows are also available in many types of materials such as hardwood, softwood, aluminium and Upvc to mention few. The glass may be plan or have coloured glass, lead lights or latticework to make a window more ornate.

Window frame

In this post I am talking about a traditional casement window with a fanlight, however many of the terms used relate to all styles of window.

Window frame

The window frame consists of a head that runs along the top, a sill along the bottom and two jambs running vertically at either side. The frame holds the window itself either hinged as in the case of a casement window or free running as in a sash window.

Top drip

Some windows will have a top drip, this encourages the water to run off the tip of the window rather than to run down the window and glass, or even into an open window.


The casement is the part the glass sits in, the part that opens. A basic design of a casement consists of four parts, a top rail running horizontally at the top, a bottom rail that runs horizontally along the bottom and two styles that run vertically that go to make the casement. This would typically be hinged on one side or along the top and attached to the window frame.


A mullion is the central vertical part that makes up the frame on a casement window and separates two windows, for example a opening casement window and a fixed pain window.


A transom is a horizontal part separating two windows, for example a fixed pain and a fanlight / vent window.

Window sill

The sill is at the bottom of the frame and attached to the two vertical jambs to complete the window frame, the sill will slant away from the window to encourage water to run away from the window frame, the sill will also have grove underneath it to allow the water to drip off and to stop the water running back under the window frame.

Many new windows now come with trickle vents, these are air vents that are in the head of the frame that have a grill on the outside and a closing vent on the inside, this allows air flow into the property and help prevent condensation forming on the windows.

How to paint around a window and get a professional looking job

If you are unconfident of cutting in around windows or glazed doors you can use this following tip.

To stop getting paint on windows or glass panelled doors when you paint them you can use masking tape to mask the glass.

Take time and care to only get the tape on the glass.

Place the tape on the glass, you can then run a sharp knife along the frame to ensure the tape is only on the glass, but being careful not to cut into the frame.

Once you have gone around all the window/s you are ready to paint. Paint around the window, glazes door etc as normal.

Leave the paint to fully dry, and then remove the tape carefully. You may need to cut the tape around the window to ensure it doesn’t pull the paint off as you remove the tape, take your time and you will have a newly painted window or glazed door.

The other method is to paint around the window or glazing in your door and paint slightly onto the glass, leave to dry and then clean the paint off the glass with a sharp blade.

Both methods take longer to do than simply cutting in but if you don’t have a steady hand or aren’t confident either method will give you a more professional final job.

UPVC – Don’t get stuck with silicone!

Posted by admin
August 11th, 2008

If you decide to have new UPVC windows and doors fitted one top tip for future decoration of both inside and outside of your property is as follows.
Mastic gun
Please do not allow the fitters to seal around you door or windows with silicone, as this cannot be over painted.

It’s OK to seal with silicone on the exterior if you don’t have painted rendered walls, as painting to the exterior obviously isn’t required.

If you have had your windows and doors sealed with silicone, rather than a sealer that can be over painted, you could be in for problems when it comes to decorating. Paint and wallpaper will not stick to silicone. You may have to have the silicone removed and replaced with a sealer that can be painted over, such as flexible decorators caulk.
