B2 Fire XPS Extruded Polystyrene Floor Insulation Boards Fiberglass Tile Backer Board

Damp Prone Wet Area Construction: Stop repeated wall mold and water seepage; all in one waterproof substrate replaces separate waterproof membrane to simplify wet zone renovation.

Heavy & Messy Cement Board Work: End heavy manual carrying and dusty cutting; lightweight backer board enables clean onsite processing and lowers worker fatigue

Loose Tile & Hollow Tile Troubles: Avoid unstable tiling base; reinforced facing creates reliable bonding layer so finished tiles stay intact year round.

Extra Multi layer Working Procedure: Ditch separate waterproof plus insulation layers; combined backer board fulfills two functions in one panel to streamline construction workflow.

Closed cell Waterproof Core: Block water molecule penetration completely to prevent board swelling, warping and wall mold growth in long term humid environments.

Integrated Thermal Insulation Property: Restrict indoor outdoor heat transfer to cut building energy consumption for heating and cooling.

High Compressive Rigid Structure: Resist heavy load and daily impact to maintain flat substrate performance for wall and floor tiling projects.

Bathroom & Shower Wet Zone Application: Rigid waterproof substrate delivers reliable tiling base whether you are doing residential shower renovation or hotel bathroom mass projects.

Basement & Ground floor Renovation: Moisture block panel protects wall cavities from ground dampness, preserving wall condition for long term underground space service life.

Custom Shower Niche & Tub Surround Build: Easily cuttable panel adapts to irregular shapes, enabling quick fabrication of niches, benches and special wet zone structures.
