Every February at around 6 o'clock, you could find my husband cooking dinner in a parka. That's how cold our kitchen was. Old and improperly insulated, nobody could figure out how to insulate the space without ripping everything apart. Finally, airseal insulators came to the rescue. They were able to blow in their expanding foam insulation into the walls and under the floor joyces disturbing absolutely nothing in the kitchen. It's a far better insulator than fiberglass, and took them all of 20 minutes to complete the job. They were friendly, knowledgable, and reasonably priced. The kitchen is toasty in the winter, and cool in the summer. The only bad news: Now my husband cooks in a speedo.
