Can you cut encapsulated insulation?
When insulation must be cut to fit, use a sharp knife or shears. If the attic already has some insulation, first fill to the top of the joist with insulation, then lay additional insulation across the joists. Do not cover vents or exhaust fan motors which protrude into the attic; cut the insulation to fit around them.
What is encapsulated insulation?
Encapsulated insulation is fiberglass insulation that comes wrapped in a polyethylene vapor retarder. When insulating your crawlspace, you have several options.
Is encapsulated insulation better?
Crawl space encapsulation is great if you have issues with moisture and standing water in that area. Insulation is much better suited if you’re dealing with cold floors and frozen pipes.
Do you need insulation in an encapsulated crawl space?
You don’t need to insulate an encapsulated crawl space. Crawl space insulation can be applied between the joists or on the walls of the crawl space. If the crawl space is vented then joist insulation is recommended. If the crawl space is encapsulated either can be used but we recommend insulating the block walls.
Why should you not encapsulate a crawl space?
An un-encapsulated crawl space can introduce mold, mildew, and other contaminants into your living space. Contaminated air does not only make your indoor space uncomfortable to stay in but could also be harmful to your health.
Is faced insulation worth it?
If you want moisture protection in a wall cavity, then using faced insulation is a clear winner. However, if you want to keep the heat in in your attic from radiating into your living space, an unfaced alternative may be better. Remember, sometimes you may not have to choose between faced vs unfaced insulation.
