Window Stools

For many years, we have produced stone window sills and window stools. Slate window stools are often less expensive than hardwood on an installed basis and hardwood cannot match slate’s durability. Architects specify our materials for their natural beauty, performance characteristics and low maintenance. And because we produce custom sizes and offer several finishes, architects also appreciate the flexibility our materials afford them in their designs.

weathering characteristics

Some materials are “unfading”, meaning they will hold their basic color even after many years of exterior use. Others are “weathering” or “semi-weathering”, meaning they will change color (usually to shades of brown) when used outside. A stone’s weathering characteristic is primarily an aesthetic consideration. “Weathering” in and of itself does not adversely affect the performance or durability of a stone. See stones below for weathering characteristics.

finishes

Depends on stone selected. See stones below for available finishes.

sizes

Custom sizes for window stools and sills depend on stone selected, finish, thickness, joint width and other factors.

thickness

Depends on stone selected, finish, piece size, setting method and other factors. Generally window stools are 3/4″ or 1” thick and window sills are at least 1 1/4” thick.

edge details

We fabricate many different edge details. Exposed edges are usually honed.

joint widths

Depends on stone selected, finish, piece size and other factors.
