NORTHSLOPE WINDOW 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 NorthSlope 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 giving high performance in energy efficiency and durability.

The NorthSlope Window incorporates a top–of–the–line, energy–efficient spacer system with high–performance, double Low–E glass to offer unmatched thermal performance, meeting Energy Star requirements.  Because these products are manufactured by U.S. regional glass makers, there is the added value of still greater “locally sourced” benefits.  The window contributes toward satisfying several credits under green–building rating systems, including LEED® and NAHB's National Green Building Program.

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 NorthSlope Window by Clawson. View Window Gallery >>
