At Ryan Windows & Siding we are constantly looking for ways to make your home more energy efficient. With costs for heating and cooling your home always rising, today's energy conservation and efficiency standards call for more insulation than what your home may currently have. If your house is one of the nearly 45 million in the U.S. that are under-insulated, you're likely experiencing substantial heat loss in the winter and heat gain in the summer. This means your heating and cooling systems are working overtime year-round and wasting your money!

Why You Should Insulate - The Benefits

Without adequate amounts of properly installed insulation, your home loses heat in the winter and gains heat in the summer. That can lead to higher energy bills and uncomfortable living conditions. Insulation, which helps to control heat flow in your home year-round, provides these benefits:

  • Lower heating and cooling bills. Insulation protects your home with a thermal blanket that can help reduce costly energy loss. This helps you save on fuel bills during both the heating and cooling seasons.*

  • Sound control. Noise in your home can be reduced by strategically installing insulation to help absorb sound.

  • More comfortable living environment. A well-insulated home is a more comfortable home, room to room, floor to ceiling.

  • Higher home resale value. By upgrading your home's insulation to optimum levels for your geographic region, you can expect your home to increase in value at resale time.

  • Conserves natural resources. If you increase the insulation in your home, you will decrease the amount of energy used to heat and cool it. That means fewer pollutants are released into the atmosphere. It also means fewer power plants are needed to produce energy to heat and cool your home - which helps conserve natural resources. For every BTU used to manufacture fiber glass insulation, on average 12 BTUs are saved per year.

Areas in your home to insulate

The following list refers to locations shown in the diagram above.

  1. Attics - the most important area of a home to insulate. Ceilings with cold spaces above; this includes dormer ceilings.

  2. Exterior walls - Sections that are sometimes overlooked are walls between living spaces and unheated garages or storage rooms, dormer walls, and the portions of walls above ceilings of adjacent lower sections of split-level homes.

  3. Interior walls, ceilings and floors - where sound control is desired.

  4. Band or header joists - the wall section between floor levels.

  5. Floors over unheated or open spaces - such as garages and porches. Floors over unheated basements. The cantilevered portions of floors and under windows.

  6. Basement walls

  7. Floors above vented crawlspaces - Insulation may also be placed on crawlspace floors and walls.

Ventilation / Insulation


What is Ventilation Diagram Ventilating Your Home Properly
Proper ventilation of your home is imperative for allowing excess moisture in attics and wall cavities to escape to the outside. In summer his prevents the attic from becoming a hot-box that spills unwanted heat down through the attic floor (even if the attic is insulated) into the living area, which can reduce your air conditioning costs. In winter proper ventilation can help prevent moisture from condensing on the insulation, rafters or roof deck. It can also prevent excess heat from escaping through the roof, melting snow and causing ice dams that can damage your home.

In an attic/flat ceiling. The most common ventilation method is the natural or static ventilation system, which consists of simple vent openings in your attic. Eave vents - openings under the eaves - combined with roof or gable vents provide an effective way to create positive movement of air out of the attic. Always provide at least two vent openings for proper air flow. Air will flow into one opening and out the other opening. Install attic baffles to make sure insulation does not block eave vents.

As a general rule, you should provide one square foot of net open vent area for each 150 square feet of attic floor when there is no vapor retarder in the ceiling. If the ceiling has a vapor retarder, provide one square foot of net open vent area for each 300 square feet of attic floor area.

Ideally, 50% of the required ventilation should be provided by vents located in the upper portion of your attic, with the remaining 50% provided by eave vents.

If you're planning to add insulation to your attic, it's important not to cover eave vent openings and to maintain a 1" space between the insulation and roof sheathing so that air can move freely from the eaves to the ridge or gable vents.

In a crawlspace. Providing at least two crawlspace vents will allow a positive flow of air in and out of the crawlspace. One square foot of free vent area is recommended for every 1,500 square feet of floor area covered with a polyethylene ground cover. (In crawlspaces that are unheated or have a dirt floor, it is recommended that the floor be covered with a polyethylene vapor retarder.)

Cathedral ceilings. Cathedral ceilings are sloped ceilings where insulation is installed in rafter spaces and the ceiling finish layer is fastened directly to the rafters. In this type of ceiling, a vented air space between insulation and roof sheathing is usually recommended. CertainTeed manufactures special high-density insulation for use in cathedral ceilings. R-30C (cathedral) is 8-1/4" thick for use in 10" rafters and R-38C (cathedral) is 10-1/4" thick for use in 12" rafters - this allows for a 1" air space above the insulation.
