WindowLab Approved Technology

While the concept of a window is likely as old as the first human-made structure, today's window technology embodies cutting-edge advancements, blending modern design with future-forward innovation for peak performance and efficiency. This includes our fusion welded window frames and triple-pane insulated glass units, each carefully chosen and spec’d by WindowLab and our manufacturing partners.

The Window Frame

Durable Vinyl: Ensures exceptional weather resistance and color stability.

Graphite Polystyrene Rigid Foam: Within the frame's cavities, reflecting heat, boosting thermal resistance, and enhancing the R-value with colder external temperatures.

INNERGY® Thermal Reinforcement:, Enhancing insulative properties significantly over aluminum, offers improved protection against condensation stains and superior impact resistance.

Bulb Seals: Prevent moisture penetration, improving the overall sealing efficacy.

Advanced Weatherstripping: On both frame and sash, featuring barrier fin weatherstripping for a robust seal against the elements and abrasion.

Fusion Welded Corners: Make the traditionally weakest point of the window the strongest.

Insulated Glass Unit

Low-E Glass: Specialized coatings reflect 98% of infrared and ultraviolet light, maintaining interior temperatures and protecting furnishings from fading.

Multiple Panes: Better insulation with three glass layers separated by gas, enhancing thermal efficiency.

Gas Fills: Non-toxic, clear argon or krypton gases between panes provide superior insulation compared to air.

Super Spacer®: Non-metallic, dual-seal spacer maintains pane separation, minimizes heat transfer, and excels in durability tests, achieving the lowest U-Factor in its class.

NFRC Label

The National Fenestration Rating Council (NFRC), an independent entity, provides energy performance ratings for windows, doors, and skylights, aiding in product comparison. We include the label with all our windows and are happy to share metrics during the sales process.

Key metrics include:

U-Factor: Measures insulation efficiency, with lower scores indicating better insulation.
Solar Heat Gain Coefficient (SHGC): Assesses solar heat penetration, with lower values denoting better heat blockage.
Visible Transmittance: Evaluates light entry, where higher figures mean more light passage.
Air Infiltration: Gauges air leakage, with smaller numbers showing tighter sealing.
Condensation Resistance: Indicates moisture resistance, with higher ratings signifying better performance
