What is batt insulation?

RValues. An insulating material’s resistance to conductive heat flow is measured or rated in terms of its thermal resistance or Rvalue — the higher the Rvalue, the greater the insulating effectiveness. The Rvalue depends on the type of insulation, its thickness, and its density.

What R value do I need?

Can I use r19 in 2×4 walls?

The normal R19 in a 2×4 wall will actually be far below R19 – probably no better and possibly lower than R13 insulation. R19 in a 2×6 wall does not really give you an R19 wall. It is about a R16 wall because of the feect of the “thermal short circuiting” through the studs.

Can you over insulate a house?

But there may be a theoretical point of “too much.” If a home is overinsulated and is too tightly sealed, moisture can get trapped inside. Without proper ventilation, a home can build up too much moisture, especially in the attic (warm air rises), which can cause mold problems and, overall, lower indoor air quality.

Is fiberglass insulation dangerous?
