Why Insulate? — An Introduction to Insulation
Although insulation is an important part of every building, it is often the least understood. Many people aren’t aware of the many places energy is lost in a home.
Insulation lays a foundation of energy efficiency for residential, commercial and industrial structures. It is one of the most cost-effective ways to save energy and reduce monthly heating and cooling costs. Whether you are remodeling a home or building a new business, there are many benefits of insulation:
- Increased, more consistent interior comfort all year long
- Reduced energy usage
- Lower heating and cooling costs
- Less wear and tear on HVAC equipment
- Reduced noise transmission for a quieter space
- Improved air quality
- Reduced moisture intrusion
- Less overall environmental impact
How Insulation Works
Heat flows from higher temperature areas to lower temperature areas, creating temperature fluctuation within a space. Insulation wraps your home in a protective blanket, reducing heat flow in order to keep the heat out during warmer months and the heat in during cooler months. Insulation is an excellent noise absorber and helps to reduce sound transmission from both outside and within a home, creating a quieter space with less reverberation. Insulation also allows other energy-efficient components, such as air sealing, to do their job, forming a comprehensive insulating system that helps maintain consistent temperatures and moisture levels, reduce energy usage and increase monthly energy savings.

WHERE TO INSULATE
Insulation should be installed in the walls, floors, attic space, basement and crawlspace. A more detailed list includes:
• Ceilings with unheated spaces above, including dormer ceilings
• Knee walls of attic spaces finished as living areas
• Sloped walls and ceilings of attics finished as living areas
• Cathedral or vaulted ceilings
• Around perimeters of slabs
• Floors above vented crawl spaces
• Floors over unheated or open spaces such as over garages or porches
• Basement walls
• Band and header joists
• Interior walls, ceilings or floors where extra sound control is needed
• Floors over unconditioned basements
What Is R-Value?
The “R” in R-value stands for resistance to heat flow. The higher the R-value, the higher the level of resistance and the greater the insulating power. R-value requirements vary depending on climate and building type.
Insulation Types & Materials
Insulation is manufactured in a variety of forms and materials to suit a range of efficiency, structural and budgetary needs. Each option brings its own level of durability, versatility, R-value and cost.\

How Much Insulation Is Enough?
The amount of insulation needed varies depending on location, building type and materials. We will work with you to provide the right insulation estimate for your specifications.
Things to Consider When Insulating
- What type of insulation is being used?
- Does the insulation meet or exceed local building codes and national recommended insulation levels?
- How effective is the insulation (thermal performance, acoustical performance)?
- Is the insulation resistant to moisture, fire and settling?
- Is the insulation material safe and sustainable?
- Is the insulation cost-effective?
Your House as a System
Though insulation is one of the most essential and cost-effective ways to create overall efficiency, there are many factors to take into consideration. Insulation and air sealing combined with energy-efficient appliances, windows, doors, lighting and HVAC equipment build a whole-house efficiency system that will prove beneficial throughout the year and for years to come. We can provide an in-home consultation to help you create a plan to address any energy concerns in your household.
