Right now, there are a few things you can do around your home to air seal it to save money during the winter months and during the summer.
As mentioned in Part 1, your home is a “thermal envelope”. That is the sum total of the home’s insulation systems: walls, ceilings, foundation, floors, windows, and doors. These work more effectively with good, tight fits that seal out the weather and air. By having a tight seal on your home’s thermal envelope, the less energy you waste or lose by exchanging it too often with the air outside.
Now, we’re going to look at exterior doors, the laundry center, the water heater tank, HVAC (Heating, Ventilation, and Air Conditioning), attic insulation, attic ventilation and rain gutters.
Presenting The Doors!
We all want our doors to be attractive, secure, and weather proof. Like windows, when they are properly installed and kept in good condition, they can save you energy and money. If your door is hard to close or open, moves the whole door frame when you open or close the door, rattles when it is closed, or you see daylight and feel a draft coming from around it, then your door needs work.
When a door doesn’t close correctly, it obviously fails to seal. If your exterior door is difficult to open or close, the first thing to look for is if something is caught in the door or if something is sticking out from the door frame, such as a screw head not fully tightened against the hinge. Next, determine with a carpenter’s level whether the door is hanging plumb (straight up and down) and if the door jambs are parallel to each other. Sometimes, a screw head not tightened into the hinge can prevent a door from closing properly and over time deform and loosen the door frame or the door. Also, check to see if any hinges move toward or away from the door jamb or if they wiggle. Hinges should be tightly fastened to the door and the door jamb with no other movement except at the hinge joint.
Once I lived in an old house and the back door was hard to close because the whole frame moved with it. It was one of those things I kept putting off to fix. Then one night, I pulled the door shut so hard that I pulled the entire door and door frame out from the wall of the house. I tacked it back in place for the night but the next morning, I settled down to repair it. The original nails had rusted down to the thickness of thread while the wooden shims that kept the door seated properly had rotted because moisture got inside the door frame.
If your door frame moves when you open or close the door, don’t put it off repairing it like I did. Fix it now. First, remove the casing from both the inside of the door and the exterior. Be careful – often in older homes, door casing and other moldings are unique or are no longer available. Sharp edged casing pry bars are perfect for this. With a little patience and care, you can remove the casing without damaging it too much. A putty knife and a claw hammer are also useful. Again, be patient and careful – you are disassembling not destroying.
After you remove the casing, look for any damage to the wood making up the door frame; such as if it is rotten or split. Check to see if the shims are in place and intact. If everything looks right, check the frame to see if it is plumb. Add shims as needed and check that the door opens and closes correctly. Usually, it is easier to tack a scrap 1& #8243; × 2& #8243; across the door when it’s closed to seat the door frame properly. When it’s plumb and shimmed, carefully nail the frame into place. Next, vacuum debris from the area and seal up seams and gaps with either caulk or expanding foam. Re fasten the casing and cover up the old nail holes with color matched wood putty.
If you can close a kleenex in your door and then pull it out easily or if your door rattles from noise or the wind, it means it’s just not seated snuggly. The easiest starting place to for this fix is to add weather stripping. Usually, doors made over the past 25 years have had weather stripping built onto them. But being a door is rough work. Over time, the weather stripping gets stripped from the door. In some cases, the same weather stripping types are still used by the door manufacturer and can be easily replaced. Usually with much older homes, it’s not the case. You’ll be either replacing worn out weather stripping someone else applied, or you’ll be putting on brand new.
First, measure the gap between the door surface and the door jamb at several places. Add about 1/16 of an inch to this measurement and this will give you a rough thickness of the self adhesive foam or felt you will need to apply. Typically, I apply the foam stripping to the door jamb. Since the door jamb doesn’t go anywhere there’s less of a chance for something bumping against it and tearing off the foam. The door, on the other hand, is meant to move and will encounter all sort of things in its travels. As mentioned, you want the door to close firmly. Be sure to buy more foam than you will need so you can add and adjust the foam until you have a good seal.
If your door is in too bad of condition to repair, then it really is no longer a matter of weatherization but security. Seriously consider replacing it. Residential exterior doors come in three standard widths: 30, 32, and 36 inches.
Generally, the most insulating material for an exterior door is wood because it doesn’t conduct heat as easily as metal, vinyl, or fiberglass. That being said, most inexpensive wooden doors don’t fare well over time. They wear quickly in the areas that have the most contact (door handles and foot area), their mounting screws can loosen or tear, and depending on the harshness of the weather they can dry out and split. Steel doors provide better security and stand up to wear but they conduct heat. Wood core steel doors and foam core doors last longer, are stronger, and better insulated. Fiberglass doors usually are the most strong, durable, and well insulating but tend to be more expensive.
Door Sweeps and Door Jambs with Vinyl Weather stripping
A door’s most drafty area is along the bottom where it meets the door threshold. Most thresholds are aluminum or wooden ridges that meet the bottom of the door and form a seal. However, since the door is constantly being opened and the threshold is being stepped on, the factory installed weatherization can wear out quickly. It can be quickly and easily replaced with a self adhesive vinyl strip that hangs down from the bottom edge of the door. You attach it on the interior side of the door.
There is another kind of door sweep that uses multiple vinyl strips to block drafts. Somewhat more expensive, but it slips on over the bottom edge of the door and is held on with screws.
One product I have used with great success is pvc door jambs with built in vinyl weather stripping. Mounted on the outside of your door, these door jambs can either replace your existing jambs or slide over them. The vinyl weather stripping can be pushed up snugly against the door to keep out drafts when the door is closed. Use a circular miter saw to make the proper angled cuts so they can be mounted attractively in place. When they are in position, they can be quickly nailed or screwed into place and then painted. While I like these, there are many other similar kits that might be more suitable for your particular job.
The Laundry Center
The big energy users in the laundry area are the washer and the dryer. The typical washer uses about 0.256 kWh per load. The main cost is obviously the amount of hot water the is used during each load. Top loading washers use up to 40 gallons while front loaders use 10 24 gallons. It is easy to cut costs here by washing in warm or cold water. However, the main energy savings comes from drying your clothes. Even though modern washing machines do an excellent job of extracting the water from clothes by spinning them, they still need to be dried.
Dryers tend not to be very energy efficient because they have one job: force dry, heated air into a rotating drum to evaporate water. Dryers use ten to fifteen percent of domestic energy in the United States. Dryers also cause lint. Lint comes from fibers in your clothing coming loose as the clothes tumble across each other in a dryer’s hot drum. Lint not only collects in your dryer’s lint trap but also through the dryer’s duct work. If lint begins to obstruct or clog your dryer’s duct work, the evaporated water from your nice, clean clothes will not leave the system. If the water is trapped, it will take longer and longer for the dryer to work. Therefore, once a year, pull your dryer away from the wall, detach the duct from the bottom of your dryer, and pull out as much lint as you can from the dryer and the duct. The first time you do this, you might be surprised how much you pull out. You’ll also notice a big improvement in the time it takes for your dryer to dry your clothes.
During the cooler winter months when you are heating your home, you may notice your home feeling drier. While not always a bad thing, if your skin feels dry and itchy or if you notice your sinuses feeling raw and irritated more often, maybe your home is too dry. One way around this is to disconnect your dryer vent tubing from the duct work leading out of the house. Place a nylon sock over the end of the vent tubing and tie it in place with a long twist tie or rubber band. (Make sure you block up the vent going outside). This way, every time you run your drier, you will heat and humidify your house too.
Hanging your clothes not only save energy but also helps them last longer. Dry your clothes on a drying rack or clothes line. If you can’t hang them outside, you can hang them inside by buying a retractable clothes line (outside models are also available). Set up the line in a hallway of your home and hang your clothes to dry while you are at work. Place a large floor fan in the hallway to help circulate the air. Tumble clothes in the dryer for a few minutes until they are warm. This will relax the fibers and you’ll avoid having wrinkled or stiff clothes from hanging.
