The results show that the oxygen index of the thermal insulation board is 35, the board is carbonized at high temperature, does not melt and shrink when meeting fire, and has no drop. The thermal conductivity is as low as 0.025. The thermal insulation effect is outstanding, which can effectively meet the protection of frozen soil layer in tunnel engineering in alpine area.

The surface is compounded with excellent reinforced aluminum foil to reflect the heat source radiation and improve the freeze-thaw protection of frozen soil layer.

What is the best type of insulation for energy efficiency in ?

The best type of insulation for energy efficiency depends on your building’s needs, climate, and budget.

Spray Foam Insulation: Offers the highest R-value (~R-6.0 to R-6.5 per inch), providing exceptional air sealing and moisture resistance. It’s ideal for irregular spaces and maximizing energy savings.

Fiberglass Insulation: Affordable, widely available, and easy to install. With an R-value of ~R-3.0 to R-4.3 per inch, it’s a good option for walls, attics, and floors.

Rigid Foam Boards (Polyiso, XPS): Excellent for energy efficiency, with R-values of ~R-5.0 to R-6.5 per inch. Best for basements, exterior walls, and roofs.

Stone Wool (Rockwool): Fire-resistant and soundproof, with an R-value of ~R-4.0 per inch, making it great for soundproofing and safety.

Pro Tip: Consider your climate zone. In colder regions, higher R-values are essential, while in warmer areas, moderate insulation may suffice.

What is R-value, and why is it important for insulation?

R-value measures an insulation material’s resistance to heat flow. The higher the R-value, the better the material insulates.

Why It’s Important:

-Helps maintain a consistent indoor temperature, reducing energy bills.

-Prevents heat loss in winter and heat gain in summer.

-Affects the comfort, energy efficiency, and overall performance of your home or building.

Typical R-values by Material:

Fiberglass: R-3.0 to R-4.3 per inch.
Spray Foam: R-6.0 to R-6.5 per inch.
Cellulose: R-3.2 to R-3.8 per inch.
Rigid Foam Boards: R-5.0 to R-6.5 per inch.

The required R-value varies by climate zone. For example, colder areas like Zone 6 (Minnesota) may require R-49 in attics, while warmer areas like Zone 2 (Florida) need only R-30.

What are the most cost-effective insulation options for ?

If you’re looking to balance performance and affordability, here are the best options:

Fiberglass Insulation: The most budget-friendly choice (~$0.40-$0.70 per square foot) with solid R-value performance. Ideal for walls, attics, and floors.
Cellulose Insulation: Affordable and eco-friendly (~$0.50-$1.00 per square foot). Made from recycled materials, it offers good soundproofing and thermal performance.
Spray Foam Insulation: Though initially expensive (~$1.50-$4.00 per square foot), it pays off in long-term energy savings due to its superior air sealing.
Mineral Wool (Rockwool): Costs slightly more (~$0.80-$1.50 per square foot) but provides excellent fire resistance and soundproofing.

Pro Tip: Consider energy rebates and incentives in your area for added savings on insulation upgrades.
