Product Description

Vapor Tight Polyurethane Foam Insulation Board Closed Cell Moisture Proof Low Conductivity Panel

Product Description

Vapor Tight Polyurethane Foam Insulation Board is a rigid PUR / PIR panel engineered for humid, condensing and wash-down environments, where a moisture proof core and a vapour tight build-up matter as much as the insulation value itself.

The closed-cell structure above 93% (PUR) / 95% (PIR) is the barrier against water vapour, and with water absorption at or below 5% (PUR) / 4% (PIR) the core stays dry and keeps its low thermal conductivity.

Water vapour permeability is about 6.0 × 10⁻⁹ g/(Pa·m·s) or lower, so the panel resists vapour drive far better than open-cell or fibrous insulation and does not lose R-value when humidity rises.

Thermal conductivity stays as low as 0.022 W/(m·K), so the board combines moisture proofing and high thermal efficiency in a single closed-cell panel.

A core density of 40–60 kg/m³ gives a compressive strength at 10% deformation of at least 180 kPa (PUR) or 220 kPa (PIR), so the panel also stands up to normal handling and light service loads.

Even a closed-cell board relies on a continuous vapour barrier and staggered joints; moisture that bypasses the facing can still reach the core, so the build-up must be sealed at every edge and penetration.

Typical uses include cold store and freezer walls and ceilings, chill rooms, wash-down areas, food and beverage plants, swimming pool and spa buildings, and humid industrial spaces.

The board is cut to size on site with a fine-tooth saw and fitted with tightly butted joints; where a project faces heavy condensation, an aluminum foil facing is recommended to reinforce the vapour barrier.

PUR covers general humid duty from –50 °C to +100 °C, while PIR adds a wider temperature span and a higher B1 fire rating where both moisture and fire performance are required.
