Buying Guide

Choosing the right skylight inner dome can transform your RV into a brighter, more welcoming space. With so many options, it’s easy to find one that fits your needs. Here’s what to consider when making your choice.

Size:
Measure your skylight opening carefully. Most domes fit standard sizes like 14″ x 22″, but always double-check to ensure a perfect fit.
Material:
Look for durable materials like ABS plastic or polycarbonate. These are lightweight, impact-resistant, and built to last.
Light Transmission:
Choose a dome with high light transmittance (like 88%) for maximum brightness. Clear windows let in more light, while tinted options reduce glare.
UV Protection:
UV-coated domes block harmful rays, protecting your RV’s interior from fading and damage.
Installation:
Opt for domes with pre-drilled holes or included screws for easy setup. Some may require sealant for a secure fit.
Insulation:
Domes that trap air between layers help reduce heat transfer, keeping your RV cooler in summer and warmer in winter.
Design:
Consider the finish (clear, white, or tinted) and trim to match your RV’s style. A clean, finished look adds to your space’s appeal.
Compatibility:
Ensure the dome works with your existing outer skylight for a complete and functional setup.

With these factors in mind, you’re ready to upgrade your RV with confidence. Enjoy a brighter, more inviting space on your next adventure!
