What type of glass panel should I choose? Solar Low-E or Reflective Glass?

Choosing the Right Glass for Your Ekodome Geodesic Dome

If you're building a geodesic dome house, eco dome, or greenhouse home with glass panels, choosing the right type of glass is essential for energy efficiency, climate control, and visual aesthetics.

Both Solar Low-E (low emissivity) glass and Reflective Glass help manage sunlight and heat—but they work differently and suit different needs.


Key Differences at a Glance

Solar Low-E Glass

  • Allows visible light in while blocking infrared (heat)

  • Transparent, non-reflective coating

  • Clear, natural glass appearance

  • High light transmission for a bright interior

  • No privacy—see-through both day and night

Reflective Glass

  • Reflects both solar heat and visible light

  • Metallic, reflective coating (silver/aluminum)

  • Mirrored or metallic aesthetic

  • Reduces interior brightness

  • Daytime privacy only; transparent at night


Solar Low-E Glass

Best for: Balanced climates, homes prioritizing natural light and insulation

  • How It Works: Low-E glass has an ultra-thin, transparent coating that reflects infrared radiation (heat) while allowing visible light to pass through.

  • In Cold Climates: Reflects interior heat back inside, improving insulation.

  • In Warm Climates: Blocks a portion of the sun’s infrared radiation to reduce heat gain.

  • Light Transmission: Allows more natural daylight without the heat.

✔ Ideal for geodomes that are used for living, working, or year-round shelter
✔ Great for maintaining a clear view and consistent daylight inside your dome house


Reflective Glass

Best for: Hot climates, domes that prioritize heat control and privacy

  • How It Works: Coated with a metallic layer (silver or aluminum), reflective glass bounces solar heat and visible light away from your structure.

  • Heat Control: Reflects a high amount of solar radiation, keeping interiors cooler in hot climates.

  • Appearance: Creates a mirrored effect on the outside—great for privacy during the day.

  • Privacy Note: At night, reflective glass becomes transparent. Curtains or blinds may be needed for full privacy.

✔ Great for greenhouse domes or eco domes in sunny regions
✔ Offers solar control with a sleek, modern aesthetic


Which Glass Is Best for Your Dome?

The right choice depends on your:

  • Climate (hot vs. cold)

  • Purpose (residential, greenhouse, event space, etc.)

  • Desired light levels

  • Aesthetic preference
