1. What is a sash window?
Ans. A sash window is a window with many movable panels known as sashes. These constitute the frame that holds the glass panes together, divided by astragal bars.

2. How to paint sash windows?
Ans. Pull the top half of the sash window down and paint the top first. Then the lower half. To get the best finish, apply at least two coats. Allow drying for as long as possible without closing the window. Avoid moving the frames up and down, keep the windows in the closed position, and once the paint dries, you can use it regularly.

3. How to clean sash windows?
Ans. Take a vacuum or brush and remove the built-up dirt; use a micro-fibre cloth and suitable glass cleaner liquid for glass cleaning. Pull the sash down entirely and clean the inside and outside surface of the top part using a sponge and soapy water. Remove the remaining dirt from the frames with a moist, soapy cloth, making sure to dry them afterwards to remove any extra water.

4. How do sash windows work?
Ans. Two movable parts, commonly known as sashes, make up a standard sash window. A pulley and weight mechanism inside the window frame allows them to move up and down. A weight inside the window frame counterbalances the weight of a sash when it opens.

5. Are sash windows safe?
Ans. Sash windows are highly secure, providing at least as much security as most other windows.
