Three-layer press-in vent insulator that reduces heat transfer through the roof vent opening. Reflective outer surface, 2-3/4" foam core, removable synthetic fleece inner layer. Fits standard 14" x 14" RV roof vents. Keeps the RV cooler in summer and warmer in winter.
The Camco 45192 is a press-in roof vent insulator designed to plug the 14" x 14" roof vent opening from the inside — reducing the heat and cold that transfer into the RV through an uncovered vent. Even with a vent lid closed, the opening and thin plastic cover allow significant thermal transfer in both directions: solar heat pours in through a south-facing vent in summer, and warm interior air leaks out through any vent in winter. The 45192 addresses both directions at once.
It is constructed in three layers: a reflective surface on the outside (room-facing side when installed) that blocks solar radiation and reflects radiant heat, a 2-3/4" thick foam core that provides the primary thermal resistance, and a removable synthetic fleece cover on the inside that can be taken off for cleaning. Installation takes about 30 seconds — press it up into the vent opening until it seats firmly. No tools, no adhesive.
• 1x Camco 45192 Vent Insulator (reflective surface + foam + fleece cover) Installation: Press the insulator up into the vent opening from below — the foam compresses slightly and grips the vent sides to hold in place. No adhesive or tools required. To remove, simply pull down from the interior.
• 45192 — With reflective surface, white, 14" x 14" (this item) • 45195 — Without reflective surface (foam + fleece only), 14" x 14" • 45196 — Black-out version with reflective surface — for complete light blocking • 45191 — Reflective interior vent cover (attaches to vent lid face, not press-in) Choose the 45192 for the best combination of solar blocking and thermal insulation. Choose the 45196 if blocking all light through the vent is also important.
Summer: Install in any roof vent not actively being used for ventilation — particularly vents exposed to direct sunlight. Solar gain through a 14" x 14" opening adds meaningful heat load to the interior. Winter: Install in all roof vents during cold-weather camping or storage to prevent warm air from escaping through the vent opening. Storage: Installing insulators in all vents during long-term storage keeps the interior temperature more stable and reduces moisture condensation.
