Glass

Conservation 800

High-Performance Insulated Glass System

  • Advanced double-pane design delivering the clarity of double-pane glass with performance approaching triple-pane efficiency.
  • Triple silver-coated Low-E Plus glass combined with a pane of low-iron, Low-E glass for exceptional clarity and energy performance.
  • Center-of-glass U-Factor: 0.20 (compared to 0.39 for standard clear triple-pane glass).
  • Dual-sealed insulating glass units featuring Polyisobutylene (PIB) primary seal and silicone secondary seal for long-term durability.
  • Double-strength glass for enhanced strength and durability (many standard windows use single-strength glass).
  • Lifetime Seal Failure Warranty for lasting peace of mind.
  • Solar Heat Gain Coefficient (SHGC): 0.27, helping reduce unwanted solar heat gain during warmer months.
  • Premium stainless steel warm-edge spacer system designed to improve thermal performance and reduce condensation.
  • Industry-leading seal reliability with one of the lowest seal failure rates available.

HGI’s Conservision 800 combines advanced glazing technology with exceptional energy efficiency. Multiple layers of silver-based Low-E coatings, metal oxide treatments, protective layers, and argon gas work together to minimize heat transfer—helping keep your home warmer in the winter and cooler in the summer.

Optional Upgrades

Three quietly impressive things you can add at consultation.

  • Self-Cleaning Glass: UV light loosens dirt, rain rinses it off. Your windows essentially clean themselves between actual cleanings.
  • Built-In Blinds: Sealed between the panes. Never dust them. Never untangle them. Adjust them with a small slider on the frame.
  • Stained Bay/Bow Seat Boards: For bay or bow windows, the interior bench can be stained in Light Oak, Dark Oak, Cherry, or Brazilian Pecan. Hand-finished by Amish craftsmen.
