loose block window

Here's How:
Measure the opening.  With our opening the width varied from 34 1/4" - 34 1/2" and  height varied from 34 1/2" - 34 3/4".  Use the shorter dimensions (34 1/4" x 34 1/2") to bulid your window.  We recommend your finished window be 1/4" - 1/2" smaller in width and height than the opening. 

Our dimensions required us to use 8" blocks and 1x4 for framing.

Here's how we calculated the block size:
Four 8" x 8" acrylic blocks           =       32"
Two T-Bar (track) @ 1/4" thick   =       1/2" 
Two 1x4 @ 3/4" thick                     =   1 1/2"
Total finished size                          =     34"
(Frame material added 2" to the overall width and height.)

Measure Width, Top, Middle & Bottom.
(Use shortest dimension)

Measure Height: Left, Middle & Right.
(Use shortest dimension)

Cut two pieces T-Bar (Track)  to the same width as blocks & cut two pieces 1/4" less than blocks.
(NOTE: If a miter saw is available, simply apply the full length of t-bar to the 1x4 and miter the corners as needed.)

Cut two 1X4 2" inches
longer than blocks and
cut two 1X4 1/2" longer
than blocks. Apply adhe-
sive to back of track.
