Camco RV Roof Vent Insulators: Foam, Reflective & Skylight Sizes
Interior RV roof-vent insulators and shades reduce direct heat transfer or sunlight through an existing ceiling opening. Camco offers foam inserts for standard 14-by-14-inch vents, a longer 14-by-22-inch skylight insert and lighter reflective or vinyl shades. These accessories mount inside the RV rather than replacing the exterior roof cover or hinged vent lid.
Foam insulation, skylight insert or shade?
Standard 14-inch vent foam inserts
Camco 45192 and 45195 have white removable covers, but only 45192 has the reflective backing. The black 45196 also has reflective backing. All three are identified for compatible 14-by-14-inch interior openings.
Longer 14-by-22-inch skylights
Camco 45197 is the longer silver model with a removable cover. Do not try to match it to a standard square vent based on the 14-inch side alone.
Simple interior vent shade
Camco 42913 is a cream vinyl vent shade with mounting hardware. It is not a thick foam block and should not be used as a structural roof-vent part.
Removable reflective Sunshield
Camco 45191 is a 17½-inch-square reflective shade fastened with hook-and-loop strips. Measure the trim area; its outside dimensions are different from the nominal 14-inch opening.

|---|---|---|---|---|
| 45192 | Foam vent insulator | 14 × 14 in | White removable cover | 3-inch foam with reflective backing |
| 45195 | Foam vent insulator | 14 × 14 in | White removable cover | 3-inch foam without reflective backing |

These accessories provide shade or insulation at the interior opening. They do not repair roof leaks or replace an exterior roof-vent dome, lid or fan assembly.
Measure before choosing an insulation insert
- Measure the clear ceiling opening and the surrounding interior trim. A 14-by-14-inch roof vent may have a different visible trim opening.
- Use 45192, 45195 or 45196 when a compatible square foam insert is intended. Choose by backing and cover finish, not by colour alone.
- For 45197, confirm the longer skylight opening and any dome or frame projection that affects insertion depth.
- For hook-and-loop 45191 or vinyl 42913, check the available surface for attaching the shade without blocking required controls.
- Remove the insulating accessory when ventilation, emergency operation or access is needed. Check the vent manufacturer's instructions before operating with an insert installed.

Each product card links to the exact catalog manufacturer number for additional information and availability.
Exterior roof-vent covers are different
For an exterior dome that sits above the vent, see Camco Aero-Flo and standard roof-vent covers. Insulation plugs and shades are fitted from inside and do not replace a weatherproof roof vent lid or dome.
