Modern technology of blanket insulation today is considered the best insulation for attic.
Best rigid insulation for attic.
Among commonly used types of insulation there are mineral wool or fiberglass rolls and batts rigid fiberglass board loose fill materials cellulose mineral wool etc.
So it s time to pay close attention to what s happening up there.
Rigid foam insulation offers as much as double the r value of traditional fiberglass batts according to the united states department of energy.
This additional r.
Rigid foam offers a high r value per inch of thickness and can be cut to fit almost any space.
It s a good choice for.
The ideal attic insulation r value is different than the ideal wall insulation r value.
It is often used as a layer of continuous insulation on exterior walls and in the roof.
While most of them pack a lot of r value into a thin layer but you also have to consider how the insulation will affect the performance of your project the overall costs and the best method to get the bang for your buck.
Used in this way the foam lowers the loss of energy through framing members a phenomenon called thermal bridging and increases the overall r value of the roof or wall assembly.
Rigid foam insulation.
You can mix the type and material of insulation too.
Insulation ratings can be improved by adding more layers of insulation.
They are very effective in exterior wall sheathing interior sheathing for basement walls and special applications such as attic hatches.
Proper attic insulation is the best way to prevent heat loss in the winter and retain cool air in the summer.
The most common materials include expanded polystyrene similar to styrofoam extruded polystyrene and polyisocyanurate.

Both can be added to uninsulated attics or layered over existing material.
