Product Overview
This extruded polystyrene foam board provides a lightweight yet high-performance solution for door cores and insulation layers, delivering exceptional thermal resistance and moisture protection in a single material. With a density range of 28-38 kg/m³, it offers easy handling during manufacturing while providing sufficient structural rigidity to maintain door integrity. Suitable for interior and exterior doors, this waterproof XPS foam board meets the diverse requirements of modern building standards, contributing to LEED and other green building certifications through its energy-saving properties.
Material
The insulation board is manufactured from high-quality extruded polystyrene (XPS) using an advanced extrusion process that creates a uniform closed-cell structure. This production method involves melting polystyrene resin and forcing it through a die, where expansion creates a network of small, interconnected cells with cell sizes averaging 0.05-0.1mm. The closed-cell structure is inherently waterproof, with no need for additional vapor barriers. The material contains no organic binders or fillers that could promote mold growth, ensuring long-term stability in humid environments. It is free from ozone-depleting substances, with a low global warming potential (GWP) and zero volatile organic compound (VOC) emissions, meeting strict indoor air quality standards such as GREENGUARD Gold certification.
Product Advantage
Thermal Insulation Performance
This XPS foam board achieves a thermal conductivity of ≤0.034 W/(m·K) at 25℃, providing superior heat resistance that reduces door heat loss by up to 40% compared to traditional insulation materials. When integrated into door assemblies, it helps maintain consistent indoor temperatures, reducing heating and cooling energy consumption by an estimated 10-15% in residential applications. The insulation performance remains stable over time, with less than 5% degradation over a 20-year service life.
Moisture Resistance
With a water absorption rate of ≤1.0% by volume after 96 hours of immersion, the foam board creates an effective moisture barrier that prevents water infiltration and condensation within door structures. This waterproof property eliminates common issues such as warping, swelling, and rot in wooden doors, extending door lifespan by 5-10 years. The material's low water vapor permeability (≤1.0 perm) makes it suitable for high-humidity environments including bathrooms, kitchens, and coastal properties.
Sound Reduction
The dense closed-cell structure effectively dampens sound transmission, reducing airborne noise by up to 25 dB when installed in solid core doors. This soundproofing capability enhances privacy and comfort in residential and commercial spaces, with particular benefits for bedrooms, home offices, and meeting rooms. The foam's vibration-damping properties also reduce impact noise transmission through door assemblies.
Easy Installation
The lightweight nature (28-38 kg/m³) reduces handling fatigue during manufacturing and installation, while the material's rigidity allows for precise cutting with standard tools. The smooth surface ensures excellent adhesion to wood, metal, and composite door facings using common adhesives. The foam board can be easily routed or shaped to accommodate door hardware, with minimal dust generation compared to mineral wool alternatives.

Product Operate Guide
1. Select insulation materials based on the type of door. Metal doors can be insulated with foam or glass wool, while polystyrene board is suitable for wooden doors.
2. Cut the insulation material to match the size of the door panel. Ensure that the material covers as much of the door panel as possible for optimal insulation.
3. Attach the insulation material to the door panel using glue or sealant. Make sure there are no gaps at the edges during application for a seamless fit.
4. Pay special attention to the door edges as they are critical for maintaining insulation. Use windproof tape or rubber strips to seal these areas, preventing cold air from entering through the gaps.
5. Enhance the door's airtightness by applying windproof tape along the door seams. This additional measure helps to further prevent air leakage and improve heat retention.
