Insulation (cont. p. 6)

Doors and Windows 

Don’t neglect doors and windows in your insulation planning.  The types of doors and windows you choose and how they are weather-sealed are very important.

 

 

Window tape provides extra insulation as well as a moisture barrier.  Have your framer do the application.  I prefer the method of bottom layer first, then sides, then top.

Exterior doors should be solid-core wood, or steel or fiberglass with a foam insulated core.


Windows should be double-pane with “Low-E” (emittance) coating.

Low-E coating reflects radiant heat, helping keep warm air inside in winter and hot air outside in summer.


This photo shows the application of expanding insulating foam.

The foam is sprayed into the crevice between window frame and wall stud, an area where regular wall insulation cannot be effectively applied.

Foaming of window and door edges should be part of the package of your insulation contractor.
