TREADLIGHT™ LARCH WINDOWS by CLAWSON

One of the Greenest – and Most Beautiful --  Windows You'll Ever
Look Through.

We are pleased to announce the arrival of one of the most unique, greenest, and most handsome windows manufactured anywhere in the world -- the "Treadlight™ Window" by Clawson.  Framed in Treadlight™ larch, harvested only from forest restoration sites, this window highlights the beautiful honey and cinnamon grain and dark pinhole knots of the wood, while the window's "Energy Star"– rated efficiency cuts energy loss.  The glass is manufactured by U.S. regional sources, adding still greater "locally sourced" environmental benefits to the window.  The complete window itself is made by Clawson Windows of Missoula, Montana, with over 50 years experience in window manufacturing.  Many styles and sizes are available in the Treadlight™ Window by Clawson.

• Energy Star Rated (0.33 U–factor) using Low E–366 with Argon and Duralite spacers.
• Locally and sustainably harvested small–diameter Treadlight™ larch available for interior on clad and exterior for all–wood.
• Complete window systems available for Casement, Awning, and Fixed windows.

• Exterior options are extruded aluminum clad or all–wood.
• Low VOC interior factory finish available.
• Grown, harvested, milled, and manufactured in the U.S. – Northern Rockies.
