What is the R-value of insulation board?

It provides an R-value of 6 per inch of thickness and often comes foil-faced to help reflect radiant heat.

Is R Tech fire rated?

TYPE IV PREMIUM FIRE RATED INSULATION Cost Effective. R-Tech is typically less expensive than other comparable insulation products, its factory laminated facer also offers installation savings. Proven Performance.

What is an R and R Tech?

R-Tech is a high-performance, rigid insulation consisting of a superior closed-cell, lightweight and resilient expanded polystyrene (EPS) with advanced polymeric laminate facers. R-Tech is an ENERGY STAR® qualified insulation and can contribute towards LEED® credits.

Is insulfoam flammable?

Combustible substance. Minimize dust generation and accumulation. Use methods to minimize dust. Routine housekeeping should be instituted to ensure that dusts do not accumulate on surfaces.

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

Thermablok® Aerogel
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 R Tech a vapor barrier?

Q: Can R-TECH be an air barrier or Weather Resistant Barrier (WRB)? R-TECH by nature is an air barrier, and with the seams taped, it becomes a vapor retarder. It is also a moisture barrier, as it is hydrophobic, and is a weather resistant barrier when joints are taped with appropriate products.

What insulation is fireproof?

Fiberglass insulation is made of glass combined with plastic polymers and is naturally fire-resistant.

Is R tech waterproof?

Water Resistance. Facers provide a surface that is virtually impervious to moisture.

Is polystyrene fire resistant?

Polystyrene is highly flammable and ignites at relatively low temperatures. It has been linked with huge fires, often in commercial buildings and warehouses, where its use is more common.

Is R 15 insulation good?

Both R13 and R15 provide similar thermal performance, but it’s always best to look at your options before making your final choice. Recommended R-values for insulation go as high as R-60; typically, the farther north you go, the higher the suggested R-value.

What insulation has the lowest R-value?

How well insulation works is expressed by its R-value, which measures resistance to the flow of heat….Comparative Insulation R-Values.

Which insulation has the highest R-value?

Answer Wiki. 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.

What is the are value of high density foam?

Installed insulation R-value: The installed insulation R-value depends somewhat on the system manufacturer but generally speaking, high density foam (2.0 pcf) ranges between R-5.5 and R-6.5 per inch for the aged R-value, and low density foam (0.5pcf) has an R-value of approximately R-3.6/inch.

What is the best insulation foam board?

Extruded polystyrene (XPS), also known as blueboard, acts as the best insulating foam board for below-grade applications, according to the U.S. Green Building Council.

What is the are value for crawl space insulation?

Recommended Insulation Levels for the Crawl Space. The recommended R-value for crawlspaces in all zones of the United States and Canada is R-19. In some very moderate climates like those on the Pacific Coast , R-13 or R-15 may be sufficient.
