Windows For a Work Space

This is a project making windows for a work space. Simplicity and economy are a priority.


This is one of the eight clerestory lites. They open from the top with a transom hook. At ten feet off the floor they will admit north light, free wall space for the work shop, and release excess heat from the room.


Hopper sash are hinged at the bottom. To keep the hinges off the sill they are mounted on a stop on the sill that elevates them above moisture. This requires a substantial rabbet in the sash. Larger is better. A full size bottom rail and a 1″ haunch is essential to avoid weakening the joint.

Any 3×3 butt hinge will do. Removable pin is nice for assembly and maintenance.


The side weatherstrip drains in front of the sill stop. The bottom will weatherstrip between the hinge leaves.


A sub-sill or sill nosing will tongue into the leading edge of the sill and create a rabbet for screen or shutter.

The sash in this project are made from salvaged old growth Douglas Fir. The jambs are of second growth Douglas Fir from Glu Lam stock. The sills are Canadian Douglas Fir moulding grade stock. These are all economy materials. However, seeking salvaged on a demand basis can be far more costly and wasteful than simply purchasing new Old Growth stock. The key to making salvage material economical is to salvage it one self or purchase from a distressed seller/broker. It must also be of very high quality. Otherwise, much time and effort can be wasted.


Hopper can be combined with a fixed sash to make large windows like these. These will light the work benches. There will be no direct draft to the work surfaces but air from above when wanted. A large overhang protects from direct sun while the capacious size admits abundant reflected light.


All done.
