MOST HOMEOWNERS DON’T REALLY UNDERSTAND HOW IMPORTANT THE INSULATION IS NEEDED TO GIVE YOU COMFORT AND REDUCE THOSE ENERGY BILLS IN YOUR HOME. BELOW IS SOME SIMPLE INFO ON INSULATION.
HOW INSULATION WORKS
You need insulation in your home to provide resistance to heat flow. The more heat flow resistance your insulation provides, the lower your heating and cooling costs.
Heat flows naturally from a warmer to a cooler space. In the winter, this heat flow moves directly from all heated living spaces to adjacent unheated garages, basements, and even to the outdoors. Heat flow can also move indirectly through interior floors, walls and ceilings wherever there is a difference in temperature. During the cooling season, heat flows from the outdoors to the interior of a house.
To maintain comfort, the heat lost in the winter must be replaced by your heating system and the heat gained in the summer must be removed by your cooling system. Properly insulating your home will decrease this heat flow by providing an effective resistance to the flow of heat.
Insulation’s resistance to heat flow is measured or rated in terms of its thermal resistance or R-value.
HERE ARE THE BASIC CATEGORIES OF INSULATION
LOOSE FILL INSULATION
Insulation that is made out of small chunks of fibers. It is also known as blown in insulation because it is blown in with a blower, a giant vacuum cleaner that works in reverse.
With batt insulation, insulative fibers are woven together to create a blanket of material. Batt insulation is available in 16 and 24 inch wide rolls usually in 8 ft. sections to fit standard spacing between the framing members in walls and ceiling joist. A paper or foil moisture barrier is installed on one side of this type of insulation which becomes the backing. The backing always is laid toward the inside of the house.
Insulative fibers that are tightly sandwiched together between 2 layers of foil, creating a solid insulative material that looks a lot like plywood. Rigid Insulation is usually installed in between roof sheathing and roof covering when no attic exists.
Spray Foam Insulation usually works in the most convoluted and irregular areas where normal insulation is hard to reach. Unfortunately this method usually only works if you have an open wall from remodeling or add on.
DIFFERENT INSULATION MATERIAL
Fiberglass Insulation is the most popular and most widely available type of insulation. You can purchase it as either batt style or loose filled. It’s one of the least expensive and the batts are easily installed. Its not flammable and resist water damage.
Fiber glass batt is spun from molten glass and sand into fibers and is an extremely effective insulating material because tiny pockets of air resist the flow of heat and cold.
Fiber glass loose filled insulation is an extremely effective insulating material because its fibers prevent air movement and the resulting heat loss to resist the flow of heat and cold. It is designed for use in attics and hard-to-reach locations such as corners, nooks and crannies. It is installed dry, and because it will not settle over time, maintains its full R-Value over the life of the home.
ROCK AND SLAG WOOL
Rock and Slag wool batt is similar to fiber glass except that it is spun from slag and other rock-like materials instead of molten glass. It is sometimes called mineral wool. Mineral wool insulation was among the earliest commercial insulation types.
Rock wool (or slag wool) loose filled insulation is similar to fiberglass except that it is spun from blast furnace slag (the layer of impurities that forms on the surface of molten metal) and other rock-like materials instead of molten glass. The production of rock wool uses by-products that would otherwise be put in a landfill. Rock Wool insulation is well suited for locations where it is difficult to install other types of insulation, such as irregularly shaped areas, around obstructions (such as plumbing stacks), and in hard-to-reach places. Blown-in loose fill insulation are particularly useful for retrofit situations because, except for the holes that are sometimes drilled for installations, they are one of the few materials that can be installed without disturbing existing finishes. Rock wool is installed dry, and because it will not settle over time, maintains its full R-Value over the life of the home.
Cellulose is made from ground-up newspapers. It is treated with fire retardants, some of which have been known to cause corrosion of wiring and pipes. The product settles significantly over time and must be over-installed to compensate for this settling. All loose-fill insulation are required to detail their installed and settled thickness on the bag label to let consumers know the expected settled R-Value. Cellulose is applied using a mechanical blowing machine. In an attic, cellulose is not typically installed above an R-30 because its weight can cause sagging of the drywall. Most energy codes now call for R-30 to R-60 in attics.
Made from cotton or recycled scrap denim there has been little independent testing done to look at the fire performance and moisture absorption of these products. Similar to cellulose insulation, these materials require the addition of fire retardant chemicals because they are combustible. Some fire retardants used in these products are know to cause corrosion of pipes and wiring.
THE R-VALUE OF INSULATION
R-value indicates an insulation’s resistance to heat flow. The higher the R-value, the greater the insulating effectiveness.
The R-value depends on the type of insulation and includes its material, thickness, and density. When calculating the R-value of a multi layered installation, add the R-values of the individual layers. Installing more insulation in your home increases the R-value and the resistance to heat flow.
The effectiveness of an insulation’s resistance to heat flow also depends on how and where the insulation is installed. For example, insulation that is compressed will not provide its full rated R-value. The overall R-value of a wall or ceiling will be somewhat different from the R-value of the insulation itself because some heat flows around the insulation through the studs and joists. Therefore, it’s important to properly install your insulation to achieve the maximum R-value.
The amount of insulation or R-value you’ll need depends on your climate, type of heating and cooling system, and the section of the house you plan to insulate.
BEFORE REPLACING OR ADDING INSULATION TO YOUR ATTIC YOU SHOULD DETERMINE WHETHER OR NOT YOU HAVE MOISTURE PROBLEMS. PROBLEMS WITH MOISTURE CAN BECOME WORSE WITH ADDING INSULATION. INSULATION CAN TRAP MOISTURE CAUSING MILDEW AND MOLD TO GROW AND SPREAD. IN ADDITION, WHEN WATER AND MOISTURE COLLECT IN THE ATTIC, IT CAN CAUSE STAINS AND ROT. BEFORE PUTTING IN ANY INSULATION, IT IS BEST TO SEAL ALL AIR LEAKS. THIS NOT ONLY HELPS MOISTURE, BUT ALSO REDUCES HEATING BILLS BY KEEPING COLD AIR FROM ENTERING THE HOME. YOU MAY NEED TO CONSIDER A RADIANT BARRIER.
Radiant Barrier is nothing more than a light weight aluminum fabric that blankets the existing attic insulation. Radiant Barriers have hundreds of thousands of tiny holes that allow vapors to pass and prevent condensation from occuring at the ceiling level. These barriers also refelect heat from above during summer time, while at the same time holding on heat during the winter time. You install the barrier as a single sheet. Radiant barriers are not insulation, and by definition, have no R-value. However, there are some radiant barrier products that have entrapped air spaces (bubble pack or multilayer films) where an R-value may be available for the product. Testing has shown that it is more cost effective to add insulation than a radiant barrier.
Although it seems quite expensive initially, when it comes to providing electricity for your household, solar power is the best way to go long-term wise. If you want to save money on your electricity bill or live a greener lifestyle, then you should consider solar power for the home.
The initial cost of solar panels is very hefty, often costing a homeowner tens of thousands of dollars. However, once you get solar panels, the cost of your electricity bill will go down or you may not have to pay anything for electricity at all.
Basically, solar panels are a one-time cost while you’ll need to pay electricity bills every single month for the rest of your life.… Read the rest

The main purpose of a roof is to protect the home from the elements. Rainfall is the #1 culprit of water getting underneath the roof structure. Water needs to be shed away from valleys, chimneys, ridges, eaves, rakes, skylights, roof penetrations and roof to wall intersections. Water built up in these particular locations can cause serious damage to the structure in wood rot and not to mention mold which is known to cause respiratory problems. The water usually doesn’t just stop there, it can penetrate down the attic structure, to the ceiling sheet-rock or down a wall and cause even more serious issues.… Read the rest
Being a Fort Worth and Dallas area home inspector has taught me some simple methods homeowners can perform to help reduce your energy bills.
Homeowners can easily conduct a simple home energy audit for themselves to find and repair obvious issues. With a simple walk-through, you can spot many problems within the house.
Locating Air Leaks
It’s possible to save 5% to 30% per year in energy savings from reducing drafts in a home, and the home is generally much more comfortable afterward. Homeowners can check for indoor air leaks, such as gaps along the baseboard or edge of the flooring, and at junctures of the walls and ceiling.… Read the rest
Stainless steel has become very popular in many households these days. If you have this metal alloy that has become popular for sinks and appliances, you have a great surface that doesn’t corrode or rust easily. Stainless steel is easy to sanitize and clean. It actually isn’t stain-proof, it simply stains less than other steel. Chemical residues, dirty water, and even hard water can leave stains and spots on stainless steel. It can also be dented and scratched fairly easily. Manufacturers are now offering new types of finishes that diminish scratching and fingerprints.
Anyone with an appliance with a stainless steel finish, such as a dishwasher, refrigerator or oven, likes to see a streak-free surface.… Read the rest

When people think about blood sucking insects, they first picture a mosquito or tick. Did you know bed bugs are also blood suckers. The tiny, sneaky insects are spreading so rapidly across the United States that almost no region or area is unbitten, a new survey suggests. The United States has seen a 50-fold increase in bed bug infestations over the last five years, according to the National Pest Management Association. An entomologist told MSNBC, “It’s like the return of the wooly mammoth,” as many of his peers had previously never seen a single bed bug in their careers. The outbreak has affected most parts of North America and Europe, especially in urban areas.… Read the rest
If you have fuel burning appliances in your home, you owe it to your family to have CO detectors installed. Carbon monoxide detectors are great devices to use when fuel-burning appliances are used in the home. They can be very useful for keeping watch on the CO levels in the home.
Carbon monoxide (CO) can be a sneaky killer, it’s colorless, odorless, poisonous gas that forms from incomplete combustion of fuels, such as natural or liquefied petroleum gas, oil, wood or coal.
• 170 people on average in the United States die every year from CO produced by non-automotive consumer products.… Read the rest
1. Check gutters for leafs and debris and clean out if needed
2. Low areas in the yard or next to foundation need to be filled in. Low areas (negative grade toward home) will cause water to pond and if not corrected could leave you with some unwanted foundation problems. All grading around house should drop 6 inches every 10 ft away from the home.
3. If you used your fireplace over the winter, good time to have the chimney swept and cleaned and be ready for next winter.
4. Look for exterior paint issues, cracking, buckling and etc. Look for areas that need caulking.… Read the rest
