R-VALUE OF INSULATION

The R-value of any insulation material is a measure of its thermal resistance of a or the material’s ability to slow down heat flow. The higher the R-value, the more effective the insulating material is in holding the heat.

The R-value of an insulation material is usually listed in terms of R per inch.

When insulation is manufactured in a particular thickness, the R-value of the manufactured piece is printed on the packaging or material itself.

Not surprisingly, increasing the thickness of an insulating layer increases the thermal resistance.

LOOSE FILL INSULATION

Loose-fill insulation consists of granular or fluffy material that can be blown into hollow cavities or open attics. The main advantage is that it able to completely fill the installation space without having to be cut and fitted.

Loose Fill is used a great deal for walls, flat ceilings, pitched roofs and cathedral or raked ceilings.

A blower is used to apply the Loose fill insulation.

Fiberglass (R-2.3-2.8)

Fiberglass is the most common type of loose-fill insulation used in homes. It is made by spinning molten glass into long thin fibers that are bound together and then cut into small tufts or cubes.

Cellulose fiber (R-3.7 per inch)

Loose-fill cellulose fiber insulation is made from recycled paper products which are pulverized into a fibrous material and then chemically treated to make them fire and pest resistance.

Research has shown that densely packed cellulose insulation in the walls can reduce a house’s overall air leakage rate by as much as 50%

Mineral Wool (R-3.2 per inch)

Mineral wool is made by spinning molten glass, inorganic rock or slag into long fibers; a process similar to that used to make fiberglass.

One advantage of mineral wool is that it is totally fireproof and won’t melt or burn in a house fire. (Fiberglass insulation doesn’t burn, but it does melt.)

Vermiculite (R-2.4 per inch)

Vermiculite is made by expanding mica under high temperature and pressure. Because it can withstand wetting better than any other loose-fill, it is commonly used to fill the cores of blocks in foundations.

BATTS AND BLANKETS

Batts and blankets are made of either fiberglass, mineral wool, or recycled cotton material that is spun into a cohesive mat. They are suitable for:

-Cathedral or Rake Ceilings, Pitched Roof Ceilings, Timber Floors or Suspended Slabs.

The difference between batts and blankets is simply packaging. Batts are precut to roughly 4-foot or 8-foot lengths so that they will fit into a standard-height wall. Blankets are long rolls of material that are cut to length on site, usually to be used in attic floors.

Fiberglass Batts

Fiberglass batts are the most common, accounting for roughly 90% of the material used to insulate walls in new homes. It’s made from molten glass spun into microfibers.

Mineral Wool Batts and Blankets

Mineral wool batts and blankets are relatively rare.

Cotton or Natural Fiber

Cotton or natural fiber insulation is fairly new to the market. An advantage to using cotton batts is that it is non-toxic and there is no itch or irritation associated with its use.

RIGID FOAM INSULATION

Rigid foam insulation is made from several different types of plastic foam, each with a different R-value.

The most common application for rigid foam is as exterior insulative wall sheathing although it can also be used for flat ceilings, pitched roofs, suspended slabs and cathedral or raked ceilings.

Extruded Polystyrene Foam (R-5 per inch)

Extruded polystyrene or XPS is made by four manufacturers in the United States, comes in four distinctive colors: blue, pink, green and yellow; each manufactured by a different company.

Extruded polystyrene is very resistant to water penetration and is a good material for insulating foundations below grade.

Expanded Polystyrene Foam: (R-3.5 to R-4.5 per inch)

Commonly called beadboard or EPS, expanded polystyrene insulation is very similar to the material used to make disposable coffee cups — both being made of tiny beads fused together, but it has a lower R-value than extruded polystyrene.

SPRAY APPLIED INSULATION

There are several types of insulation that can be applied as a liquid. These “spray-applied” insulation materials are used mostly in new construction of walls, but some contractors use them in attics for both new construction and retrofits.

Low-density foams are sprayed into open wall cavities and rapidly expand to seal and fill the cavity.

Urethane: (R- 6.0 per inch)

Urethane is a spray-applied foam. One very effective use of urethane is as a retrofit material . This is a perfect solution to load-bearing roof areas.

Wet-spray cellulose

Cellulose insulation can be applied wet using special equipment that mixes water into the insulation as it is blown out of a hose.

“Blow-in-Blanket” system – (R-3.9 per inch)

One unique method for installing either loose-fill fiberglass or cellulose in walls is called the “blow-in-blanket” or “BIB” system.

The insulation is mixed with a small amount of water and adhesive and is then pumped into wall cavities behind a nylon scrim that is stapled to the stud faces.
