Product Description

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

Product Description

Vapor Tight Polyurethane Foam Insulation Panel is a rigid PUR / PIR closed-cell panel made for build-ups where keeping the insulation dry from water vapor is critical to long-term performance.

Its low thermal conductivity of 0.021–0.025 W/(m·K) keeps heat flow low, and the closed-cell structure of 93% (PUR) to 95% (PIR) or more blocks moisture so the panel does not lose performance in humid air.

A core density of 40–50 kg/m³ gives a compressive strength of at least 180 kPa, so the panel stands up to normal handling and light service loads.

Water absorption is at or below 5% (PUR) / 4% (PIR) by volume and vapor permeability is 6.0×10⁻⁹ g/(Pa·m·s) or lower, which is why the panel is installed with a continuous vapor barrier on the warm side and sealed joints.

PUR covers general vapor-tight insulation, while PIR adds a B1 fire rating and a wider temperature range for more demanding duty.

The panel is used across many vapor-sensitive duties rather than a single one — cold rooms, chilled and frozen spaces, duct and pipe insulation, humid rooms, tanks and general building envelopes.

Panels are installed with tongued-and-grooved or tightly butted joints, staggered and fully sealed, and any penetration is sealed with mastic so warm moist air cannot reach the cold face and form condensation.

Product Features

Vapor-Tight Moisture Proof – Continuous vapor-tight, moisture proof core keeps the insulation dry.

Closed-Cell Waterproof – Closed cells above 93% block moisture in humid air.

Low Thermal Conductivity – Thermal conductivity 0.021–0.025 W/(m·K) keeps heat flow low.

High Compressive Strength – Compressive strength ≥ 180 kPa suits normal handling and service loads.

PUR / PIR Available – PUR for general duty, PIR for higher fire and temperature service.
