ClimateGuard offers a variety of glass block window styles to complement your space. While sometimes used for decorative appeal, they are most often used for utility purposes. Glass block windows with or without vents are commonly used for privacy and security in basements and bathrooms. We use a 3” thin line block, which allows for endless design options. For ventilation and air flow, add windows (usually a hopper style) or a glass block window vent (or dryer vent).


We offer a variety of glass block window styles and sizes for easy installation in brick or wood openings. Our window panels come fully assembled and feature the following standard features:
  • Fabricated to meet highest new construction & building standards
