What is Type VI insulation?

GreenGuard Type VI 40 psi Insulation Board is designed for use in high load applications requiring compressive strength up to 40 psi. It meets ASTM C 578 Type VI requirements.

What is Type 3 insulation?

Type 3 and Type 4 polystyrene insulation are generally extruded polystyrene. The closed-cell structure provides long-term water resistance properties and excellent mechanical properties to this foam. The cells retain a gas that provides a high thermal resistance value of R5. 0/in.

What is the difference between Type 1 and Type 2 insulation?

Type-I products typically offer about R-3.9 per 25 mm or R-7.8 at 50 mm (2 in.). However, Type-II EPS, rated at 0.6 kg (1.5 lb) nominal density, has an R-value between R-4.15 and R-4.2 per 25 mm. A 50-mm thick sheet would be R-8.3 to R-8.4.

What is Type 2 insulation?

TYPE II · 20 PSI. Page 1. Description. InsulFoam II Below Grade is an engineered insulation consisting of a superior closed-cell, lightweight and resilient expanded polystyrene (EPS).

What is the R-value of 4 inch STYROFOAM?

STYROFOAM extruded polystyrene insulation is rated at an R-value of 5.0 per inch at 75°F.

What is the R-value of 4 inch rigid insulation?

R-Value Chart for EnerfoilTM Rigid Foam Faced Insulation

Thickness (Inches) R-value (in I-P/Imperial) RSI (R-value in Metric)
2.5 15.5 2.7
3.0 18.6 3.24
3.5 21.7 3.78
4.0 24.8 4.32

Can you paint R Tech?

Q: What types of paints are compatible with the insulation? Quality latex paints and primers should be used for best results. Avoid products that contain solvents such as xylene, acetone, etc. Q: Can R-TECH be an air barrier or Weather Resistant Barrier (WRB)?

What is the R value of EPS?

3.6 per inch
EPS insulation features an average r-value of 3.6 per inch. In addition to providing energy efficiency, EPS without film facers has a perm rating of up to 5.0.
