Improving or replacing garage door offers several benefits
Q: Our kid's bedroom is over our garage. The old garage door is noisy when opening. I also do projects in there during winter. What type of new door should I install?
A: There are several advantages of a new efficient garage door. It will keep you comfortable when working on your projects, reduce energy losses from the bedroom floor above it, and be quieter. If a cheap garage door was installed initially, the bedroom floor likely is not well insulated either.
Inspect your existing door first before you invest in a new insulated efficient garage door. If it is in good shape and there are no drafts coming from the joints between the panels, consider installing a garage door insulation kit. This provides an insulation value of R-8, but it will not seal up leaks through the joints.
Owens-Corning (www.owenscorning.com) makes an easy-to-install kit. It includes vinyl-backed fiberglass insulation batts, retaining clips, and tape. Cut the batts to fit the door panels. Stick tape on two spots on each panel. Stick the retaining clips on the tape and push the insulation over them. A top clip snaps over each clip to hold the insulation in place.
If you end up deciding a new garage door is needed, there are several basic options. The most common materials are wood, insulated steel, insulated fiberglass, and aluminum/glass. Of these, the insulated steel or fiberglass skins offer the best efficiency. Many insulated steel doors are “wind-rated” for severe weather areas.
If you definitely prefer the appearance of wood, but want higher efficiency, select a clad insulated steel garage door. Clopay has developed a method to attach a one-half inch-thick polymer coating on the exterior steel skin. It has authentic wood grain molded into the surface so it looks identical to real stained wood. Another option is an embossed simulated wood finish.
A very popular garage door style today is a simulated swing-open carriage type. It still rolls up like a typical panel door, but from the street it appears that it would swing open. These attractive doors typically have some type of decorative glass for aesthetics and for light in the garage.
An insulated steel door is probably the least expensive design to meet your efficiency and comfort needs. Clopay's door panels have insulation values as high as R-19. The foam inside the door can be either glued-in rigid polystyrene or blown-in urethane foam. Urethane foam has a higher insulation level, but either should be satisfactory.
When choosing a steel door, look for one with a thermal break between the outdoor and indoor skins. This is not a factor on a fiberglass door. If you have children, look for pinch-resistance panels. These are designed to push a finger out of the panel joints as the door closes. If you want glass in the door, make sure it is at least double-pane, insulated glass or low-E for better efficiency.
Q: The duct from the bathroom vent fans runs into the attic. When it is cold outdoors, water drips down off the grill on to the tile floor. What can I do to fix this?
A: It sounds as if your attic floor is well insulated and properly ventilated so the attic stays cold. Since most bathroom vents use a metal duct, the duct also gets cold. This causes the moisture to condense and it runs down and drips out the grill.
Run the fan a little longer after you shower so it clears the moisture-laden air out of the duct before it condenses. The ultimate fix is to extend the duct so it vents outdoors.
