Climate & comfort
Climate & Thermal Comfort for Transparent Domes
How a polycarbonate dome behaves in heat, cold, humidity and coastal air — and the configuration decisions that make it comfortable. Solar gain, condensation and HVAC are system questions, not single-part answers.
The honest answer
No transparent enclosure is a magic climate box.
A clear shell collects solar heat; a cold shell surface collects condensation. The working configuration combines the right shell (clear or solar-control), ventilation, shading, occupancy planning and — where the project requires it — client-supplied HVAC.
There is no single temperature guarantee. Comfort depends on climate, configuration, occupancy and operating hours; we plan the system with those inputs.
Climate selector
Start with your climate type.
Hot & sunny
Solar-control light-grey shell (70% transmission, >80% IR block), top-lift ventilation, shade curtains and opening windows. Active cooling assessed only when needed.
Hot & humid
Ventilation, exhaust, dehumidification where required, and drainage planning. Condensation risk is managed with airflow and occupancy control.
Cold & snow
Sealing, snow management around doors and vents, and a heating plan. The shell holds its properties to −40 °C; interior comfort depends on the heating system.
Coastal / salt air
Salt exposure reviewed for fixings, hardware and cleaning access. Anodised 6063 aluminium base and regular rinsing schedule.
The system
What each comfort lever does.
| Lever | Effect | When it matters |
|---|---|---|
| Solar-control shell | Reduces solar gain; 70% light transmission, >80% IR blocking | Hot, high-sun climates |
| Top-lift ventilation | Releases rising hot air at the highest point | Sunny days, cooking or events |
| Roof exhaust fan | Active air exchange | Occupied spaces, hot climates |
| Shade curtains | Blocks direct sun, adds privacy | Daytime use, bedrooms, spa |
| Opening windows | Cross-ventilation and access | Mild climates, transitional seasons |
| Client-supplied HVAC | Active heating or cooling | Extreme climates, premium stays |
Temperature performance depends on tested conditions and the complete ventilation and shading configuration. For commercial projects, HVAC sizing is confirmed locally with the project’s engineer.
Questions buyers ask us
Will a transparent dome overheat in summer?
Solar gain depends on climate, sun exposure, occupancy and operating hours. The solution may combine a solar-control shell, shade, top-lift ventilation, exhaust and opening windows. Active cooling is only assessed when the project requires it.
What causes condensation and how is it managed?
Condensation occurs when humid interior air meets a cooler surface. Ventilation, controlled occupancy, heating or dehumidification and drainage planning reduce risk; no transparent enclosure can promise zero condensation in every climate.
Do I need air conditioning?
Not in many climates. Start with airflow, shade and occupancy. If active cooling remains necessary, larger domes can accommodate a client-supplied floor-standing unit subject to layout and electrical planning.
Can the dome be used in winter?
The shell holds its properties from −40 °C to 120 °C and does not require seasonal take-down. Interior comfort depends on the heating plan, insulation configuration and occupancy.
