- Glass is fitted with movable sashes that slide vertically
- Usually, both sashes slide but some have a single hung sash where one is fixed
Casement Windows:
- Opens attached to the frame by hinges
- Most produced windows in the UK
- Easier to maintain and energy efficient
- Typically open outwards but some older designs open inwards
Tilt and Turn Windows:

What is Pointing?

Pointing fills the gaps between bricks or stones in masonry work with mortar
Improves structural integrity and appearance

Types of Pointing

Flush Pointing:
- Mortar is neatly filled between bricks to create a smooth, level surface
Weathered Pointing:
- Mortar joints are shaped to slope away from the masonry surface, aiding water runoff and preventing moisture accumulation
Keyed Pointing:
- Grooves or keyways are created in the mortar joints before applying fresh mortar, enhancing adhesion and durability
V-Grooved Pointing:
- Mortar joints are shaped into a V-groove profile, providing a decorative and distinctive finish
Beaded Pointing:
- Mortar joints are shaped into a bead-like profile using a rounded tool
Struck Pointing:
- Excess mortar is scraped away from the joints to create a smooth finish
Recessed Pointing:
- Mortar joints are set slightly below the masonry surface, creating a shadow effect
