What You Are Actually Choosing When You Pick a Dome Glazing
Most buyers choose a dome by size and price, then discover the glazing finish determines how the space feels, how hot it gets, and whether guests feel private. This guide compares clear, tinted and privacy finishes for polycarbonate domes, with the numbers that matter for glamping, dining and garden use.
Clear Glazing: Maximum Light, Minimum Barrier
Clear polycarbonate transmits 85–92% of visible light (ASTM D1003). It gives the full stargazing and garden-view experience that most dome buyers want. Trade-offs: maximum solar heat gain in summer, and no privacy from outside. For daytime dining or open gardens, clear is the natural default; for bedrooms or hot climates, combine it with shading or a tinted option.
Tinted Glazing: Controlling Solar Heat
Tinted finishes (bronze, grey, blue) cut light transmission to 30–60% and reduce solar heat gain by 20–40% compared with clear. They are the right choice for hot climates, west-facing sites, and any dome where afternoon sun makes clear glazing uncomfortable. The trade-off: stargazing at night is reduced, so tinted domes are better for dining and lounging than for astronomy.
Privacy Finishes: Frosted, Opal and Diffused
Frosted, opal and diffused glazing scatter light, cutting transmission to 40–70% while eliminating see-through visibility. Privacy finishes suit bedroom domes, toilet/shower modules and spa areas. Light transmission drops enough that interior lighting needs to be planned; the diffused effect also softens harsh sunlight, which many operators prefer for all-day occupancy.
Glazing Comparison Table
| Finish | Light transmission | Solar heat gain | Privacy | Best for |
|---|---|---|---|---|
| Clear | 85–92% | Highest | None | Stargazing, gardens, day use |
| Bronze tint | 40–60% | Reduced 20–40% | Partial | Hot climates, dining |
| Grey tint | 30–50% | Reduced 25–45% | Partial | Commercial glamping |
| Frosted / opal | 40–70% | Reduced | Full | Bedrooms, spa, toilets |
| Clear + UV | 85–92% | Highest | None | All-year outdoor (10-yr warranty) |
How Finish Affects the Guest Experience
- Stargazing domes need clear glazing and a dark site — the whole point is the view
- Dining domes work well tinted or clear-with-shade; guests want the view but not glare on food
- Sleeping domes benefit from privacy finish or blackout options for guest comfort
- Mixed-use sites should offer two finishes — clear for day spaces, privacy for night spaces
FAQ: Dome Glazing Options
Can I get clear and tinted glazing on the same dome?
Yes — Domevora domes can be specified with different finishes per panel. A common configuration is clear on the sky-facing panels and tinted or privacy on the wall panels, balancing light, heat and privacy.
Does tinted polycarbonate reduce UV protection?
No. UV protection is a co-extruded layer independent of colour. Tinted and clear Domevora panels both carry the same 10-year UV warranty.
Which glazing is best for a hot-climate dome?
Bronze or grey tint reduces solar heat gain by 20–45%. For very hot sites, combine tint with a shading skirt or position the dome away from afternoon sun.
Is frosted polycarbonate still good for stargazing?
No — frosted scatters light and cuts transmission to 40–70%. For stargazing, clear glazing is the only choice; use privacy finishes only on non-view panels.
