Using Keystones with Decorative Heads

What are Cast Stone Keystones?

Cast Stone Keystones are wedge shaped units that are used as a central design feature above windows and doors. They can be used in brickwork but are often used in conjunction with decorative heads. Using Cast Stone Keystones will add style to your property and enhance the overall appearance.

At Click Cast Stone we stock two types of cosmetic Keystones, K1 & K2.

K1 – 265/150 x 165 x 215mm
K2 – 305/150 x165 x 290mm

Cosmetic Keystones are ‘L-Shaped’ units that fit over the top of Cast Stone Decorative Heads.

What are Cast Stone Decorative Window Heads?

Cast Stone Decorative Heads are built into a wall directly above windows, doors, and other wall openings. Decorative Window Heads are primarily used to enhance a property aesthetically and are a popular choice for architectural detail because they spark interest, enhancing brick or stone elevations. Cast Stone Decorative Heads are non-structural and therefore a suitable lintel will be required beneath the units.

Keystones Used in Conjunction with Decorative Heads

Cast Stone Decorative Heads are an excellent alternative to natural stone heads and by adding Cast Stone Keystones, they really add flair to your window and door details.

NOTE: Using Keystones with Chamfered Decorative Heads will leave a small gap behind the keystone, as detailed below.
