A Breathable Home vs. a Drafty Home A Breathable Home vs. a Drafty Home June 2 nike air huarache mens blue , 2012 | Author: Mark Munns | Posted in Home and Family
We all know that a drafty home is costly; we also know an air-tight home is undesirable. Finding the happy medium can be difficult, but it is possible. Every crack and crevice in your home is an area of air leakage. Other air leakage can occur in outdoor water faucets, phone and cable lines entering the wall, bathroom and kitchen vents, furnace vents, laundry vents, chimneys nike air huarache womens pink , mail slots, garage doors and even air conditioners.
According the Smart Energy Alliance, a non-profit organization committed to providing tools and resources to consumers, reports that on average 60% of the air in a home leaks out every hour; more when weather is inclement and less when conditions are mild. That statistic is frighteningly high when you consider that fact we spend so much on heating or cooling the air before it leaks out of the home.
So what can you do to assess the amount of air leakage in your home? You can hire an air leakage professional and expertly evaluate the state of your home. An expert can conduct an energy assessment, and perform a blower door test. There are a few tests the homeowner can carry out themselves. After the sun has gone down and it is completely dark outside, shine a flashlight through all the seams and cracks around doors and windows. Have someone stand on the other side to see of light is visible. If the light is seen, then there is air leakage.
There is also the paper test. Close a door or window on a piece of letter size paper. If you can pull the paper out without it tearing nike air huarache triple white womens , there is air leakage. A further test to carry out is with an incense stick and involves depressurizing the home. On a cool and windy day, turn the furnace off, shut all windows and doors, and turn on all fans that are meant to flush air to the outside (kitchen and bathroom). Then pass the lit incense stick over common air leak areas. If the smoke is sucked through or blown out of the crack, there is air leakage.
You have done all the tests and determined there are areas of leakage. What now? For starters don’t jump to conclusions and assume your home has more holes than a pound of Swiss cheese. Unless there are gaping holes in the walls and the building is condemned, it is all fixable. Let’s tackle the points of entry first. How old are the windows? Are single paned, double paned nike air huarache triple black nz , aluminum frames, vinyl frames or fiberglass frames? Single paned, wood frame windows will undoubtedly be much less efficient than double paned vinyl frame windows. There will be an immediate 25-50% reduction in air leakage when the change is made. That is 25-50% less money spent on heatingcooling the home! Additionally, there will be much less (if any) condensation around the windows, thus reducing the mold and mildew in the walls and sills.
Take a look at the weather stripping around all the windows and doors. If it is flat, cracked or simply non-existent, then it will need replacing. This is a very simple fix that you can do yourself. Some homes experience air leakage from beneath the moldings around the doors and windows. For this type of escape nike air huarache black and red , closed cell spray foam insulation is the best solution. It can fill every crevice without you having to open the whole wall, making the windows and doors more efficient in maintaining the indoor temperature. Once the moldings are back in place on the inside and outside of doors and windows, caulk them. Caulk around all the indoor and outdoor seams of all windows, doors, air vents, and outdoor water faucets around the home. All those little crevices leak air that can add up over time.
Take a good look at the areas directly under the roofline. Attics and cubbies that are located directly under the roof are typical areas for warm or cold pockets to sit. Cold and moist pockets will of course create condensation, and eventually mold. If the underside of the roof is not covered with insulation or drywall nike air huarache nm red , look at the nails protruding through the boards. Are they rusty? Are there signs of water marks on the wood? If so, you likely have a condensation or water problem that needs to be addressed immediately.
Is there a bathroom or kitchen fan that vents into the area? Is there a bathroom or kitchen directly under the area? In either case, there is clearly moist air leaking into the attic cavity and doing damage to the structure. If you can accurately determine the leak is coming from ventilation tubing or ducting, then taping it up is all that is necessary. If you are not sure, then it may be best to apply spray foam insulation to the entire area. The foam will seal up all known (and unknown) crevices, stop mold from spreading and resist critters from making their homes in the attic space. However the biggest benefit will be the increased efficiency in heating and cooling the home.
Think of your own body heat when out on a snowy day. You wear a hat or hood to keep the heat from radiating out the top of your head. It helps keep the rest of your body warm. The same is true for the home.
Now that you have sealed up all the leaks, how can your home possibly breathe? Well nike air huarache nz , there are still passages of air penetration into the home that are necessary and used regularly. For example, the dryer vent must be clear to allow hot air from the dryer out of the building. Kitchen and bathroom vents always have air flowing through them. If there is a furnace or fireplace in the home, air is flowing through all the time as well. Each time someone leaves or enters the home air is exchanged from the outside. A bit of air flow is a healthy thing in a home. There is a fine balance to be had that every homeowner must be aware of in their own living space.
