Guide to Winterizing Your Geodesic Dome


The fall can be a great time to prepare your geodesic dome for the upcoming winter season. No matter whether you already own a dome or whether you’ve been weighing in on the benefits of investing in a dome home or greenhouse, we hope you’ll find this “Guide to Winterizing Your Geodesic Dome” useful.

Planning for inclement weather is a key step in positioning, as well as, winterizing your dome. When wintering in your geodesic dome it’s essential to be aware of seasonal weather patterns and typical snow loads specific to your area.

Begin with Good Site Planning

Starting with the basics, site planning begins with orienting your dome to maximize sunlight and take advantage of passive solar heating. Domes are known to be 30% more energy efficient than traditional structures. That said, it’s still important to think about how the sun moves throughout the day; as well as, consider seasonal changes when siting your dome’s placement.

A dome’s open span allows scattered light and warmth from walls, windows and skylights to penetrate deep inside its interior. One of the key features that people love about domes is that they are pleasant to be in – they allow lots of natural light, rendering artificial light almost unnecessary during daytime hours. People love relaxing under an illuminated dome’s romantic nightime skies, as well.

When contemplating your interior design, installing a skylight can be an effective means of introducing diffused lighting and passive heating directly from the roof level. It’s easy enough to attach a removable, velcroed or drop-down insulative cover for those cold winter nights.


Design Tips:

  • Take into account that sunlight is greatest on the south wall.
  • Morning sun is dominant in east-facing walls.
  • West-facing walls are your last chance to soak up the warmth of the sun during late afternoon, early evening hours – when the sun’s light is at its lowest angle.
  • North-facing rooms lend the least amount of natural light – perfect for bathrooms and storage space.
