Buying Guide: Key Purchase Considerations
- Opening match: Confirm the inner opening is 14″ x 22″ or 22″ x 22″ as required, and check flange dimensions for proper fit and mounting compatibility.
- Dome type: Decide whether you need an inner dome, outer dome, or a bundled system. Bundles offer comprehensive replacement and better insulation by trapping air between domes.
- Material quality: Look for thick, impact-resistant polycarbonate with UV protection to resist sun exposure, temperature changes, and hail.
- UV protection: UV coatings help protect interior furnishings from fading and reduce heat buildup during sunny days.
- Weather performance: Choose domes with robust wind resistance and weather sealing to prevent leaks in storms and high winds.
- Ease of installation: Some domes include screws or sealants; ensure you have the appropriate hardware and compatible sealants for a reliable seal.
- Aesthetic considerations: If you prefer less glare or heat, consider smoke or tinted outer domes; clear domes maximize daylight.
- Warranty and support: Check for manufacturer warranties and replacement parts availability for long-term maintenance.
