Zhongjia XPS Extruded Insulation Board is a high-performance closed-cell thermal insulation material manufactured in Guangdong, China, specially engineered for tile backer and building insulation applications. The 20-50mm extruded wall version features an ultra-dense closed-cell structure, delivering outstanding heat retention, moisture resistance and high compressive strength—core properties that make it a top choice for B2B building and construction projects worldwide. Lightweight and easy to install, this Tile Backer XPS Foam Board complies with international safety and environmental standards, effectively cutting building energy consumption while ensuring long-term, stable insulation performance. As a professional B2B supplier, we provide consistent product quality and bulk supply capacity for residential, commercial and industrial construction projects.
The dense closed-cell structure minimizes heat transfer with a low thermal conductivity of ≤0.027-0.030 W/(m·K), maintaining stable indoor temperatures and drastically reducing energy costs for heating and cooling systems.
With water absorption ≤1%, the board blocks water vapor penetration completely, retaining insulation performance even in high-humidity environments like basements and ground floors without performance degradation.
Boasting a compressive strength of 150-400kpa, it withstands heavy loads without deformation, ideal for load-bearing scenarios such as floor and roof insulation.
Weighing only 28-60kgs/m³, the board is easy to transport, cut, splice and fix on various surfaces, reducing construction difficulty, shortening project timelines and lowering labor costs for B2B clients.
It features excellent anti-aging, corrosion and UV-resistant properties, maintaining stable physical and chemical performance in harsh outdoor conditions for long-term use.
Made with non-toxic, environmentally friendly raw materials, it releases no harmful substances and meets global environmental standards, suitable for both indoor and outdoor insulation projects.

Applied to residential, office and commercial complex exterior walls, it blocks heat transfer and prevents moisture damage, ensuring a dry and comfortable indoor environment.
Ideal for ground floors, basements and garages, it bears building and vehicle loads while isolating ground cold and moisture, avoiding floor condensation.
A perfect solution for cold storage, refrigeration warehouses and refrigerated trucks, it maintains stable low temperatures and reduces refrigeration energy consumption.
Combined with waterproof materials, it forms a composite insulation-waterproof system for flat and sloping roofs, extending roof service life and cutting maintenance costs.
Used for road, bridge deck and tunnel wall insulation in cold regions, it prevents frost heave and thaw settlement, protecting structural stability of transportation infrastructure.
We offer full customization for B2B clients to meet project-specific needs: customizable dimensions (length/width/thickness) from 20mm to 150mm in thickness, density adjustment between 28-40kgs/m³, and OEM/ODM services for special colors and packaging. Customized cutting and splicing solutions are also available for complex construction scenarios, with fast sample delivery and bulk production capacity.
All B2B orders come with professional online technical support—our engineering team provides real-time answers to installation, construction and product application questions. We offer a 1-year product warranty for quality-related issues, and provide free construction guidance documents (including installation tutorials and technical parameters). For bulk orders, we assign exclusive account managers for one-stop service, ensuring timely delivery and after-sales follow-up.
