Application:

  • Clean surface to be caulked.
  • For gaps greater than 1/2″ deep, use a backer rod.
  • Insert caulk tube into the caulk gun.

Frequently Asked Questions:

What is Home Sealing?
Home Sealing is a process recommended by the EPA ENERGY STAR® program to increase the energy efficiency of your home by improving the effectiveness of the building envelope. Sealing air leaks helps to enhance the performance of your insulation and may help to cut up to 20% of your energy bill, according to the EPA. Visit www.energystar.gov/index.cfm?c=home_sealing.hm_improvement_sealing for more information.

What is a home envelope?
The exterior of your home is also called the “envelope” or shell. The insulation, outer walls, ceiling, doors, windows, and floors all work together to control airflow in and out of the structure, repel moisture, and prevent heat from being lost or gained inside your home. A high-performance envelope helps maintain a consistent interior temperature even under extremely hot or cold conditions. The goal of Home Sealing is to help improve the home envelope to make homes more comfortable and energy-efficient.

Is Home Sealing something I can do myself?
Absolutely! You can seal holes, weather-strip doors, caulk around gaps in pipes and wires, floors, basements, and crawl spaces. Remember, it's important to always air-seal before adding insulation. ENERGY STAR® has a written Do-It-Yourself Guide to help with the process of Home Sealing, which can be downloaded by going to http://www.energystar.gov/ia/partners/publications/pubdocs/Seal_and_Insulate.pdf To find out more information about ENERGY STAR®, go to www.energystar.gov
