Does Your Home Have Enough Attic Insulation?

Attic Insulation Installation Tulsa

When it comes to improving your home's efficiency, don't forget about the attic. Experts calculate that leaks in the attic floor can drain away 30 to 50 percent of your heating or cooling.Heat rises upward and migrates through cracks into the unconditioned attic space, eventually escaping through the roof or vents. In the summer, a hot attic and uninsulated attic floor can make it more difficult for you to cool your home, as heat moves through conductivity into the living space.What's the solution? In most cases, more attic insulation will do the trick.

Adding Insulation

Start your attic sealing project by identifying the various areas where energy is being lost. Lay wooden planks across joists to walk on before you start moving around.

1. Check for gaps around fixtures, pipes, wires, ducts and anything else that enters the attic space from the living space. Roll back existing insulation batts to get at all the holes; if you have loose-fill insulation, it might be better to get a professional to locate the leaks. Fix all the smaller leaks you find with caulk. For holes up to an inch wide, use expanding urethane foam. For still larger holes, use a piece of drywall to plug it, sealing edges with foam. You can also use fiberglass insulation.

2. Seal gaps around stove flues and chimneys with a sheet metal collar and heat-resistant caulk, separating these structures from insulation.

3. Put extra insulation on top of the attic hatch door. Place weather stripping around the edges of the hatch.

4. Next, check to see if the insulation on your attic floor reaches the top of the joists. If not, add more to the top or over the joists. Make sure it is evenly distributed, and reaches the sides of the attic.

5. Insulate behind knee walls.

6. Build airtight boxes with rigid foam insulation to cover recessed lighting canisters. Get professional advice about how any insulation you are considering might overheat when used in proximity to the lighting canisters.

Insulation And Ventilation: Rx For An Attic That Running A Fever

Tulsa Blown In Insulation

Hot attics can be a major source of excess heat throughout your home. As sunshine beats down on the roof, temperatures in unfinished and unconditioned attics can reach 150 degrees or higher. This heat is easily absorbed and transferred by building materials such as wood. The heat radiates downward, increasing temperatures in all areas beneath the attic. In most homes, this translates to practically everywhere within the structure. By maintaining proper levels of both insulation and ventilation in your attic, you can limit the effects of excess heat that accumulates in this part of your house.Heat transferred from your attic to your living spaces can make your home uncomfortable and cause your air conditioning system to work harder than necessary, increasing wear on the unit and causing spikes in your utility bills. Adequate attic insulation and ventilation will prevent this problem by reducing the amount of heat that accumulates in your attic.

• Insulation: Install plenty of insulation in the attic to keep out heat. Fiberglass roll or blanket insulation is commonly used between beams and joists in the attic wall, floor and roof. Irregularly shaped or difficult-to-reach areas can be insulated using loose-fill pellet insulation. Use insulation with the highest R-value possible. R-values are a measure of how well insulation resists heat flow. The Energy Star program recommends using insulation with R-values of R30 to R60 in the Tulsa area.

• Ventilation: Attic fans will increase ventilation and airflow, which moves both heat and moisture from the attic to the outdoors. Attic fans should be able to replace the entire volume of air in the attic 10 times an hour. Increased airflow will be very effective at keeping your attic and your home cooler. Contact your local trusted HVAC provider for assistance with finding an attic fan that will create sufficient ventilation for your space.

Here's How to Check Insulation Levels in Your Home

Attic insulation costs - tulsa ok

If you'd like to lower your energy bills and improve your home comfort, addressing sources of air leakage and areas with inadequate insulation can help. Checking two key areas where these problems often occur can help you decide if it's time to hire a professional to boost the insulation level and seal up air leaks.

Up in the Attic

For home attics in our region, the Department of Energy (DOE) advises insulating the floor to R-60, and correcting air leaks to reduce heat transfer with the living areas below. You can perform a couple of easy checks to assess these issues:

• When it's dark out, turn on the lights in the rooms below the attic. Go up there, close the hatch and take a thorough look around the floor to locate any leak sources where light bleeds through from below.

• To judge the insulation level, turn on your attic lights and look around again. If you see the tops of the floor joists in any spot, there's not enough insulation. If the joists are well-hidden, you likely have a sufficient amount installed.

You can fix areas of energy waste and increase the efficiency of your home by sealing the attic, installing a vapor barrier on the floor, and increasing insulation to the recommended level.

Your Exterior Walls

According to the DOE, your exterior wall cavities should have R-19 in insulation installed, and you should seal leaks in the exterior shell by weatherstripping and using caulk and expandable foam insulation. To assess these areas:

• Take off the electrical box covers on the exterior walls, then shut their breakers off. Using a flashlight, look inside each box for signs of insulation. If none is visible, your walls probably need insulation.

• At night, shut off all the interior lights in your home, then walk around shining a flashlight at the exterior walls. Get a helper to follow you outdoors to identify any spots where leaks let the light shine through from inside.

How Your Roof Affects Your HVAC System

Running the HVAC system accounts for about half of the total energy used in an average home. If you're looking for ways to reduce your household energy consumption and save money, one vital factor to consider is how your home's roof affects the HVAC system.

The HVAC System – Roof Relationship

The amount of energy needed to maintain comfort in your home is directly affected by the sun beating down on the roof. When there's a lot of heat getting absorbed through the roof, and it radiates down into your attic and living space, your HVAC equipment has to work harder to compensate, and you'll pay higher energy bills.

Factors Affecting Rooftop Heat Absorption

Research in recent years has given us a greater understanding of the role roofing material plays in how much solar heat enters homes and other buildings. This has led to the development of roofing with two key qualities that help it stay cooler and more energy efficient:

• High solar reflectance. This allows a material to reflect sunlight better, so there's less solar heat absorbed into the roof system.

• High thermal emittance. These materials release a high percentage of solar radiation that does get absorbed, which reduces how much heat can be transferred into an attic and conditioned living space.

Roofing Options That Improve Efficiency

If you want to increase your home's efficiency and you're planning to have new roofing installed in the near future, here's are some materials to consider:

• Cool asphalt shingles. Regular asphalt roofing is a poor solar reflector, so it tends to soak up heat. New cool shingles are topped with specially-treated granules to reflect the sun's rays.

• Coated metal. Bare metal can reflect sunlight, but it doesn't emit heat well. More efficient versions feature painted or granular-coated surfaces that provide both qualities.

• Clay or concrete tile. While some types of tile roofing naturally reflect sunlight and shed heat, there are also products available with treated surfaces to provide better solar reflectivity and heat emittance.

Insulation Costs - Winter Attic Safety and Savings

Tulsa Insulation Costs

Getting your attic sealed and insulated can boost your family's comfort and help you save energy both winter and summer. In our climate, temperatures in an unfinished attic can climb too high for safety many months of the year, so winter is the ideal time to have more insulating R-value added. Attic safety should still be a primary concern even when there's less risk of heat exhaustion and dehydration, so be sure to take these steps before you or a hired pro begin insulating:

Always Wear Protective Gear

Your attic can contain all sorts of injury hazards, so anyone going up there to work needs to wear proper protective gear. This means durable clothing that fully covers the arms and legs, and head protection such as a sturdy hat or helmet. Gloves and safety goggles to protect hands and eyes are needed too, and a respirator to prevent inhalation of insulation fibers.

Set Up Walking Paths

Creating walkways in your attic can make it safer and easier to access areas that need sealing and insulating. First, move any obstacles so you have clear paths to different areas, then lay down 1x4 boards to form a one-foot wide walkway. To keep the boards from slipping and wobbling, screw or nail the ends of each one to the attic floor joists.

Prevent Accidental Shocks

Do a detailed check of your attic to find any obvious or hidden electrical hazards that may cause shocks or electrocution. Check for loose wiring at floor level, gnawed or damaged wires, and open junction boxes. If you find any problems, have them fixed by an electrician before you insulate.

Light Up the Space

Good visibility is paramount for safely working in an attic. If yours only has one or two single-bulb lights, one option is to have your electrician install more. Alternately, you can put a couple of appropriately-rated extension cords and movable work-lights up there so there's plenty of illumination to safely air seal and insulate the entire attic.

What to Know About Attic Safety

You already know how hot an attic can get in the average Broken Arrow summer, but that's not the only thing you should know about attic safety. Dim lighting, low rafters, and exposed wiring are a few of the other hazards you'll need to look out for if you or a technician will be working in the attic.

Plan Ahead

Well before work begins, check the attic's structural integrity. Make sure the floor is strong enough to walk on safely. If the floor is weak or damaged, consider using plywood or planks to provide a safe walking surface. A little cleanup also improves attic safety. Remove clutter such as stored scrap lumber and drywall. To reduce risk of injury, hammer down exposed nails, tie up loose wires and cables, and mark low-hanging beams with strips of brightly colored plastic or fabric.Bring an electrician's drop light into the attic to ensure there's plenty of light to work by. Have all your tools and supplies together ready to take up to the attic to minimize the number of times you have to risk a fall by climbing up and down the attic access ladder.

Choose the Right Clothing and Equipment

Wear clothes that will protect your skin from dirt, insulation fibers, and rough surfaces. Your clothes should be loose enough to let you move freely, but not so loose they'll get caught on anything. For optimal protection, wear a disposable coverall, hair cover, shoe covers, and gloves. These protect your skin and, because they can be thrown away after use, they prevent you from tracking insulation, mold spores, and pest droppings into the rest of your house.Use an OSHA-approved dust mask or particulate respirator to keep airborne pollutants out of your lungs. You may also need fall protection equipment, such as a body harness properly anchored to a roof beam. Bring along a flashlight in case your drop light fails. In warm temperatures, take plenty of water.
