HOW CAN FIBERGLASS ENHANCE YOUR HOME?
Fiberglass windows offer the attractive appearance of painted windows while boosting your home’s energy efficiency and comfort levels. Both the interior and exterior surfaces come with a long-lasting powder-coat paint finish designed to maintain its quality for years to come.
PERFORMANCE HIGHLIGHTS

Stay comfortable indoors regardless of outdoor conditions. Whether your home sits along the coastline, perched on a mountain peak, or anywhere else, our fiberglass windows and patio doors provide the strength and stability to withstand harsh temperatures, harmful UV exposure, and corrosive salt air.
Fiberglass is the strongest, most durable material available for windows and patio doors. They won’t warp in the heat or become brittle in the cold.
FIBERGLASS PATIO DOORS
Polaris® patio doors are engineered to excel and endure with superior thermal performance and maintenance-free features — all with the refined appearance of traditional materials.
Advanced Security
Polaris sliding patio doors with reinforced multi-lock systems have achieved ASTM Grade 40+ security certification — setting the industry standard for protection.
Superior Weather Resistance
Polaris’s innovative engineering positions the sliding panel externally. When weather conditions intensify, it forms an enhanced weather seal. Additionally, the screen system remains shielded from harsh conditions.
Effortless Operation
The precision-engineered bearing system in the sliding panel ensures smooth, reliable operation for years of dependable use.
