Kingspan GreenGuard GG25-LG XPS Insulation Board is a lightweight exterior insulation solution built for durability and energy efficiency—from below-grade slabs to cavity walls. If you’re chasing moisture resistance without the bulk, this board is your reliable partner.
Key Features & Design
-
Material: Extruded Polystyrene (XPS) insulation board for superior moisture resistance.
-
Moisture resistance: Does not absorb moisture, retaining insulating properties over time.
-
R-value: 5.0 per inch of thickness, boosting energy efficiency.
-
Lightweight & Easy to cut: Lightweight, easy to handle, and easy to cut with a knife.
-
Applications: Ideal for below slab, cavity wall, and foundation applications; continuous insulation (Ci) for walls and protection against backfill damage.
-
Durability: Maintains integrity and meets/exceeds Type IV and Type X specifications.
-
Fire rating: Class A (Flame Spread 25, Smoke Developed 140) per ASTM E84 / UL723.
