Insulation is one of the most important components of any environmentally responsible building because it reduces energy consumption and the pollution that usually results. In this sense, any insulation material is a "green" product.

Insulation is a key part of the building envelope and an important element in the entire building as an integrated system. Choosing an insulation material should include considering how it works with the rest of the wall, roof, and floor system—and what additional functions, such as air-sealing, the material might serve.

Effective insulation is key to improving home energy efficiency and keeping your home comfortable. You could reduce your energy costs by up to 50% by properly insulating walls, crawlspaces, floors and garages. Ensure you have the correct R-Value for your region.

An R-Value is a rating that determines the insulating material's ability to reduce heat flow. A greater 'R' value means an increased ability to reduce heat flow. Your attic insulation should be between R-30 and R-60, depending on where you live.

A few guidelines and issues to consider when pairing insulation materials and structural elements for maximum efficiency:

Different types of insulation also have varying impacts in terms of their raw materials and manufacture. These life-cycle impacts should be considered along with factors such as R-value, air-sealing ability, and cost. The quality of installation also makes a big difference in how well insulation performs. If insulation is not installed properly, it will not achieve the energy savings its rated R-value would suggest. A California study concluded that a 4 percent void in fiberglass batts (like fibrous blankets or roll) resulted in a 50 percent decrease in insulation effectiveness.
