YUNVI RV Skylight Insulator 14x22x2.8 in — reflective vent pillow, 2.8" foam core for heat & draft control

YUNVI's 14 x 22 x 2.8-inch RV skylight insulator is a removable vent pillow that blocks heat, cold and drafts while fitting standard 14"×22" RV vents.

Designed for motorhomes, campers and travel trailers, this RV vent insulator combines a reflective outer layer with a thick elastic foam core to reduce radiant heat transfer and improve interior comfort. It ships vacuum-packed for compact delivery and includes hook-and-loop fasteners so you can secure it inside the skylight quickly. The product balances easy installation, non-slip grip and durable construction for seasonal temperature control without permanent modification to the roof hatch.

How does the insulator reduce heat and cold inside an RV?

The insulator uses a reflective outer surface to bounce back radiant heat and a 2.8-inch elastic foam core to slow conductive heat flow. This combination cuts down on sun-driven warming and helps reduce nighttime heat loss through the skylight opening.

• Reflective exterior reflects solar radiation away from the cabin.
• 3-inch (2.8") foam core provides thick thermal resistance.
• Seals against drafts when pressed into the skylight opening.

Is it easy to install and secure during travel?

Yes — installation is tool-free and fast. The soft but resilient foam compresses for insertion, then expands to fit snugly. Four hook-and-loop strips are included to anchor the insulator for added security during movement or when driving.

• Compress-and-push insertion fits the 14"×22" sunroof opening.
• Includes 4 hook-and-loop fasteners for a firmer hold.
• Silicone-grain texture on sides prevents slipping once installed.

Will the product arrive ready to use if vacuum packed?

The insulator is shipped vacuum-compressed to save space; it typically reforms quickly but may need time to fully regain shape. Expect noticeable recovery within 10 minutes and full restoration within 48 hours after unpacking before final installation.

• Vacuum packaging reduces shipping volume for efficient delivery.
• Quick reshape begins within minutes of opening the package.
• Allow up to 48 hours for complete expansion before trimming or permanent fitting.

How does the design prevent slipping or movement?

The insulator's bottom and perimeter feature silicone-grain, non-slip particles that help it stay seated in the skylight pocket. That friction, combined with the foam's expansion and the supplied fasteners, minimizes movement during bumps or wind.

• Non-slip silicone particles on bottom and four sides add grip.
• Elastic foam expands to create a snug interference fit.
• Optional hook-and-loop strips secure the pad in place.

Who is this for: RV owners, van lifers and campers who want a removable, non-permanent solution to improve temperature control at a 14" × 22" skylight. It's useful for those who need quick installation, packable shipping, and a cover that both reflects sunlight and adds foam insulation without altering the vehicle's structure.
