HOW DOES THE BATTIC© DOOR WHOLE HOUSE ATTIC FAN SHUTTER SEAL WORK?
The Battic© Door Whole House Attic Fan Shutter Seal works like a storm window for your whole house fan!

There are gaps around and between the shutter under your whole house fan! This is just like having an open window to the outdoors! In the cold winter your heat flows right out and cold air flows right in; and in the summer your air-conditioning flows right out and the heat flows right in!

The Battic© Door Whole House Attic Fan Shutter Seal covers and seals the Whole House Fan Shutter from the house side, in effect sealing off this area and blocking the transfer of air and moisture. It also helps to prevent the entry of noise, attic dust, pollutants, insulation, insects, and rodents into the living area from the attic through the whole house fan.

The Battic© Door Small Whole House Attic Fan Shutter Seal kit consists of a 36" x 48" piece of 3/16" thick foam insulation. It is attached with velcro to the attic fan shutter from the house side, effectively limiting air leakage between the conditioned house and the unconditioned attic.

The Battic© Door Whole House Attic Fan Shutter Seal installs in minutes! Access into the attic is NOT required. The shutter seal is installed over the shutter at the start of the heating season, and removed at the end of the heating season, saving your energy costs 24/7!

In order to stop drafts and conserve energy loss - you must reduce the air transfer between the conditioned house and the unconditoned attic. Building and Energy Codes require this!

The Battic© Door Whole House Attic Fan Shutter Seal provides an air seal - reducing any air leakage, and restors the insulation that was removed from your ceiling when the whole house fan was installed.

The Battic© Door Whole House Attic Fan Shutter Seal is working for you 24 hours a day, 7 days a week, 52 weeks a year - reducing drafts, improving comfort, and saving you energy costs all year-round! In all kinds of weather!

WHAT IS THE INSULATION MADE OF?
The insulation is made of a durable, attractive, non-toxic, white-colored, space-age foam, only 3/16" thick, yet has an R-value of R-8. The foam air seals and insulates the attic fan, stopping heating and cooling loss and air leaks. The insulation is a Class A/Class 1 fire rated foam with superior thermal performance. No fiberglass – no itching.

WHAT DOES THE KIT INCLUDE?
The kit includes everything needed to immediately stop air leaks and heat loss through your whole house attic fan. A supply of special insulation and a supply of velcro is provided. 3 sizes of kits are available.

HOW DO I INSTALL IT?
The kit is very easy to install following these instructions:

1. Leave the velcro attached to itself so that the release liners are on opposite sides. Peel the release liner off of one side of the sides of the velcro and adhere it to the outer edge of the shutter. Trim as needed with scissors.

2. Peel the opposite side of the release liner off. Attach the piece of insulation (silver side up) onto the velcro. Firmly rub the insulation in to the velcro to get a good bond. Leave overhang on all four sides.

3. Remove the insulation. The velcro will now be seperated. One side of the velcro is attached to the louver, the other to the silver side of the insulation. Trim the insulation with scissors around the velcro. Reinstall the insulation onto the velcro.

HOW MUCH DOES IT COST?
The price for our small kit (enough to seal a shutter up to 3' x 4') is $29.50. Larger sizes available.

CAN I PURCHASE A LARGER KIT?
Yes. 3 size kits have are available to fit just about any fan shutter available. Should you encounter one that is larger and you want a larger kit, please contact us!

WHAT COLOR IS THE VELCRO?
The Velcro is white. It is made by 3M and is a quality product.

WHY DO YOU USE VELCRO AND NOT MAGNETS?
Most shutters are aluminum and magnets will not stick to aluminum. We have experimented with magnetic tape. Magnetic tape is dark brown and will leave a dark brown strip on your ceiling that is unattractive. There are vinyl coated magnetic tapes available in white color. We have tested these extensively and we find them not strong enough to hold the foam pad in place, the pad falls off and you will find it on the floor. Furthermore the magnetic tapes are much more expensive adding unnecessary cost to the kits. Velcro is far superior to magnetic tape!
