Product Description

XPS Foam Board Properties

XPS foam is an insulating panel manufactured with fully recyclable material. It is produced from extruded polystyrene, a material that doesn't deteriorate. The foam structure is constructed with very fine closed cells that provide excellent physical and mechanical characteristics.

Heat Insulation Performance

XPS foam doesn't conduct heat due to the special cell structure. When XPS panels are laid as a wall liner or floor underlay, any heat from the room or truck body will be reflected back towards the surface. This helps to prevent heat wastage, and thereby, lowers your energy consumption and carbon footprint.

Damp Protection

XPS foamed products are also water-repellent. They never rot or support mold growth and help hold back any dampness from the structure. XPS panels are also resistant to cement, plaster, and most alkalis except organic solvents.

Soundproof

In addition, XPS foam has excellent sound-insulating properties, which makes your truck or room floor "quieter" to walk on. It is an ideal product that reduces sound transmission to the level below.

FAQ

Professional FAQs About XPS Tile Backer Boards

FAQ 1: What is an XPS Tile Backer Board and what is it used for?
Answer:
An XPS Tile Backer Board is a lightweight construction panel made from extruded polystyrene (XPS) rigid foam core with cementitious or fiberglass-reinforced surface layers. It is primarily used as a tile-ready substrate in wet and dry areas, including bathrooms, showers, kitchens, floors, and walls.
The closed-cell XPS core provides excellent thermal insulation, zero water absorption, and high compressive strength, while the cement-coated surface ensures strong adhesion for ceramic tiles, porcelain tiles, stone, and mosaics. Compared with traditional cement boards, XPS Tile Backer Boards are easier to cut, faster to install, and reduce overall structural load.

FAQ 2: Is XPS Tile Backer Board waterproof and suitable for wet areas?
Answer:
Yes. XPS Tile Backer Board is inherently waterproof due to its closed-cell extruded polystyrene core, which prevents water absorption and capillary action. When combined with sealed joints and appropriate waterproof tapes or membranes, it becomes a fully waterproof system suitable for showers, steam rooms, wet rooms, and bathroom floors.
Unlike gypsum-based boards, XPS boards do not swell, rot, or lose mechanical strength when exposed to moisture, making them a preferred solution for long-term durability in wet environments.

 
FAQ 3: What thicknesses and densities are available for XPS Tile Backer Boards?
Answer:
XPS Tile Backer Boards are typically available in thicknesses ranging from 4 mm to 100 mm, depending on application requirements.

4–10 mm: Wall tiling and renovation projects
12–20 mm: Standard bathroom walls and shower enclosures
30–50 mm: Floor insulation and underfloor heating systems
50–100 mm: High thermal insulation or structural leveling applications
Density usually ranges from 30–45 kg/m³, with compressive strength options commonly between 250 kPa and 700 kPa, ensuring sufficient load-bearing capacity for floor installations.

 

FAQ 4: Can XPS Tile Backer Board be used with underfloor heating systems?
Answer:
Yes. XPS Tile Backer Board is widely used in underfloor heating systems due to its low thermal conductivity and high compressive strength. The board acts as an insulating layer, directing heat upward into the tiled surface instead of losing energy into the subfloor.
Its dimensional stability under temperature fluctuations ensures that tiles remain secure without cracking, making it suitable for both electric and hydronic floor heating systems in residential and commercial buildings.
 
FAQ 5: What are the main advantages of XPS Tile Backer Board compared to traditional cement board?
Answer:
XPS Tile Backer Board offers several key advantages over traditional cement boards:
Lightweight: Up to 50–70% lighter, reducing labor and installation time
Waterproof: No water absorption, ideal for wet areas
Thermal Insulation: Improves energy efficiency of buildings
Easy Installation: Can be cut with a utility knife, no dust or heavy tools required
High Strength: Suitable for wall and floor applications with proper thickness selection
These benefits make XPS Tile Backer Board a cost-effective and high-performance solution for modern tile installation systems.
