CoreGuard Plus™

Sierra Pacific wood windows and doors are protected by CoreGuard Plus™ wood treatment, the best protection in the industry. CoreGuard Plus is a patented process that, when needed, penetrates wood right to the core to repel water, so their windows and patio doors are less likely to warp or swell and have superior dimensional stability. In addition, CoreGuard Plus contains fungicides and insecticides to deeply protect all wood species from pests and rotting. Amazingly, this strong protection comes from a naturally organic, water-based treatment with nearly zero VOC's, which helps them maintain their strict environmental stewardship.



Each window and door composition provides different advantages. Our aluminum clad wood windows and patio doors offer the best of both worlds. Warm, natural wood on the inside is protected against insects and moisture with our patented, naturally organic CoreGuard Plus™ preservative. Sierra Pacific premium all-wood windows and doors are crafted with select grade wood interiors and exteriors. They offer the flexibility to finish the exteriors as desired, with the option to change colors in the future. At the core of our advanced H3 is Fusion Technology, the perfect integration of extruded aluminum, vinyl and solid wood. Its patent pending design and construction give it an industry-leading seal against the elements. Nearly maintenance free construction and an attractive price point make vinyl a popular choice for many of today’s homeowners.


At Sierra Pacific, they believe healthy trees, good water quality and enduring wildlife habitat are the natural result of sound forest management practices. That's why they adhere to the environmental protection standards of the Sustainable Forestry Initiative® (SFI) and go beyond the forestry regulations in California and Washington – the highest standards in the world.
