Today, Sierra Pacific products are installed in 30 countries around the globe, with a focus on residential and light commercial construction in North America. Their anodized collection is AAMA 2604 or AAMA 2605 powder coated for greater surface hardness, scratch resistance and color retention, than ordinary liquid paint. Their wood is treated and protected against insects and moisture with our patented, naturally organic CoreGuard Plus™ preservative. Their insulated glass uses No-Metal TrueWarm® Edge polymer structural foam spacers. This dramatically improves energy efficiency and reduces seal failures often caused by the more common metal spacers.
