What Makes the Starmark Evo Window so Impressive?
The Starmark Evo window is meticulously crafted with Advanced Polymeric Composite, giving it beauty, performance and durability that outshines It’s competitors in today’s crowded market.
Advanced Polymeric Composite
The construction material of the Starmark Evo is what really makes it a stand out amongst its peers. APC provides a solid sash and frame construction that does not require additional insulation. These rigid, interlocking pieces allow for a tight seal to minimize air leakage and drafts.
Premium Glass Coating and Spacer Options
The Starmark Evo uses an advanced robotic system that uses heat and compression for a flawless glass spacer seal, preventing condensation for a clear, damage-free view. The Starmark Evo Heat Seal Coating harnesses the sun's warmth for increased energy efficiency in cold climates. Alternatively, Sun Seal Coating blocks solar heat, keeping interiors cool and comfortable in warmer areas.
Solid Sill Construction
A one piece solid sill improves drainage and eliminates the need for weep holes that tend to collect water and freeze in the winter months. The unique dual dam construction also decreases air infiltration and improves overall window performance.
All Starmark Evo windows have met the KeyStone Certification Guidelines that ensure each window is built to its stated specifications. Certification also includes annual factory inspections to ensure quality management systems meet rigid standards. This means peace of mind for homeowners.
Everyone at WoW went above and beyond, and exceeded my already high expectations. Our house is now warmer, quieter, and looks so much better!
