What insulation has highest R-value?

Vacuum insulated panels

have the highest R-value, approximately R-45 (in U.S. units) per inch; aerogel has the next highest R-value (about R-10 to R-30 per inch), followed by polyurethane (PUR) and phenolic foam insulations with R-7 per inch.

Which type of insulation is most effective?

Aerogel

is more expensive, but definitely the best type of insulation. Fiberglass is cheap, but requires careful handling. Mineral wool is effective, but not fire resistant. Cellulose is fire resistant, eco-friendly, and effective, but hard to apply.

scores an R-value of 3.7. So overall, rolled fiberglass insulation is slightly more effective at blocking in and out heat than its blown counterpart.

What is the thinnest insulation with the highest R-value?

Thermablok® Aerogel

is a revolutionary advancement in thermal technology offering the thinnest insulation available to prevent thermal and cold bridging. Classed as a Super Insulation, Aerogel has the highest insulation value of any known material with the lowest thermal conductivity value of any solid (0.015W/mK).

Is a higher R-value better?

Buying Insulation

“R” means resistance to heat flow. Here’s what to know: The higher the R-value,

the greater the insulating power

. Almost all insulation products have to tell you their R-value — including duct wrap.

What is the thinnest most effective insulation?

OPTIM-R

is Kingspan’s thinnest insulation. It comprises of a rigid vacuum insulation panel (VIP) with a micro porous core which is evacuated, encased and sealed in a thin, gas-tight envelope which gives an outstanding thermal conductivity of 0.007 W/m.K.

Is R-13 wall insulation good?

Although the U.S. Department of Energy rates R-13

insulation as “good” for use in walls in southern areas

of the country, it rates R-19 insulation higher, designating it as “great.” That is because R-19 insulation provides more thermal insulation than R-13 does.

How do you insulate a house?

2. Attach 1-inch foam board insulation.
3. Install siding over the insulation.
4. Replace old windows with energy-efficient units.
5. Caulk window trim and use weatherstripping to reduce air leaks.
