Save on energy year-round without blocking the sun's rays. The AirSkirts™ AirLight™ Skylight Insulator lets the sunshine in while preventing energy from escaping through your thin skylight cover. This inflatable insulator fits in your standard sized skylight (just select the correct size) and is made of a durable, clear PVC material that stays in place without any kind of adhesive, using only air pressure to keep it in place.To be sure, measure the inside of your skylight or vent and verify that it's the correct size.
The 21"x14.25" is for the rectangular skylight often found in the hallway.
Heat rises, and your thin skylight dome provides virtually no insulation. Why let your precious energy be whisked away? Use less propane, electric heat, or air conditioning. Recommended for year-round use.
Includes a Schrader (car or bicycle tire) to HC valve adapter.
This product requires an AirSkirts Electric Air Pump or other HC compatible pump (typically used for inflatable kayaks, boats, and SUPs), or an HC valve adapter (included) and a pump that can inflate a bicycle or car tire (Schrader valve).
