Product Description

Product Description

Our XPS insulation board is manufactured with fully automated extrusion production lines in our own professional factory, adopting virgin polystyrene raw materials to form a complete closed honeycomb cell structure. It features ultra-low thermal conductivity, nearly zero water absorption, outstanding compressive resistance and stable flame retardant performance, solving heat loss, damp penetration and ground deformation problems for various construction and infrastructure projects.

Compared with ordinary EPS foam panels, our XPS insulation maintains consistent thermal efficiency for decades without performance attenuation. We provide multiple customized options including density, thickness, dimension, fire rating and aluminum foil surface lamination, matching demands of residential buildings, commercial real estate, underfloor heating systems, cold storage, road anti-freezing engineering and underground basement damp-proof projects. With complete test certificates and stable mass production capacity, we support OEM & ODM bulk supply for global insulation distributors, engineering contractors and building material wholesalers with competitive factory direct prices.

Core Performance

Outstanding Thermal Insulation

Uniform honeycomb closed-cell structure (over 99% closed cell rate), thermal conductivity ≤0.028 W/(m·K). Much better heat retention than EPS, cut air conditioning & heating costs significantly, long-lasting insulation efficiency without attenuation.

High Compressive Strength

Compressive strength ranges 150–700 kPa based on density options. Resist heavy loads, no deformation under long-term pressure, perfect for floor heating, parking lots, green roof and road foundation anti-freezing layers.

Low Water Absorption & Anti-Mold

Water absorption rate below 1%. Dense closed cells block moisture penetration completely, no mildew or performance drop in damp environments like basements, swimming pools and cold warehouses.

Long Service Life & Weather Resistance

Stable from -40℃ to 70℃, anti-aging, acid & alkali corrosion resistant. Service life reaches 30–50 years under normal construction conditions.

Custom Flame Retardant Grade

Available B1 flame retardant (hardly combustible) and B2 retardant grades, low smoke density, meet international building fire safety standards for exterior wall projects.

Lightweight & Easy Installation

Density 30–45kg/m³, lightweight yet sturdy. Easy to cut, glue and fix with tools, shorten construction period and reduce labor cost.

Wide Application Scenarios

Building Construction

Flat & sloped roof inverted insulation, green planting roof

External & internal wall thermal insulation, basement damp-proof layer

Underfloor heating system insulation floor layer

Balcony, swimming pool waterproof insulation

Heavy Load Ground Projects

Underground parking lot load-bearing insulation

Highway, bridge deck & airport runway anti-freezing layer

Square, terrace ground compression-resistant substrate

Cold Chain & Refrigeration

Cold storage, frozen warehouse wall & floor insulation

Refrigerated truck, shipping container inner liner

FAQ

Q1: What’s the difference between XPS and EPS foam board?

XPS has fully closed-cell structure, lower water absorption, higher compression strength and better thermal performance, suitable for damp and load-bearing areas. EPS is lighter with lower cost for simple wall insulation only.

Q2: Can I get customized size and thickness?

Yes. We accept full customization on dimensions, density, flame retardant grade and aluminum foil surface.

Q3: What’s your MOQ?

Minimum order quantity is 100 cubic meters for standard models.

Q4: Do you provide fire retardant XPS boards?

We supply B1 high flame retardant and B2 retardant grades to meet different national building codes.

Q5: How long is the service life of XPS insulation panel?

10–30years under normal construction environment, performance will not decline obviously.
