Building Insulation Basics

Course Outline

Building insulation is a very important design consideration. Properly insulated buildings can save energy resource and money significantly. This course is designed to help engineers and architects learn how to properly insulate a home. In this course you will learn how to insulate attic hatches, basements, ceilings, attics, crawl spaces, slabs, and walls. In addition, it also provides helpful tips on air sealing, moisture control and R-value calculation. Although the course materials are tailored for residential construction, the insulation principles are applicable to commercial construction. This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of course materials.

Course Summary

Energy codes typically require a thermal boundary between a conditioned space and an unconditioned space or between building interior and exterior. To save energy resource, the building enclosure should be insulated continuously without gaps. Proper insulation should be considered for floor slab, crawlspace, basement, walls, ceilings and attics. Openings in the building enclosure, like for windows, doors, electrical outlets, plumbing pipes, and lighting fixtures, need to be sealed so that the insulation is continuous.
