Yes, you can add extra insulation when you buy a geodesic dome, depending on the type of dome cover and frame you have. Extra insulation for domes can help you improve the thermal performance and comfort of your dome, especially in extreme weather conditions.
Here are some examples of extra insulation for domes:
Thermal bubble insulation: This is a layer of plastic bubble wrap that has a reflective coating on both sides. Thermal bubble insulation can be attached to the inside of the dome cover, creating an air gap that reduces heat transfer. Thermal bubble insulation can reflect up to 85% of radiant heat, keeping your dome cool in summer and warm in winter.
Quilted insulation liner: This is a layer of heat/cold insulated fabric that is quilted between two layers of cotton. Quilted insulation liner can be hung from the dome frame, creating a cozy and luxurious look for the interior of the dome. Quilted insulation liner can add 10mm of thickness to your existing insulation, enhancing its effectiveness.
Floor insulation: This is a layer of insulation that is placed on the ground under your dome foundation, such as concrete slab, wooden deck, or metal platform. Floor insulation can prevent heat loss or gain through the ground, which can account for up to 25% of your dome’s energy consumption. Floor insulation can be made of different materials, such as rigid foam boards, mineral wool, or spray foam.
Sealing and Weatherproofing: Ensuring that the dome is well-sealed and weatherproofed is as crucial as adding extra insulation. Address any gaps, cracks, or openings that may compromise the insulation’s effectiveness. Airtightness contributes significantly to insulation performance.
