Introduction:
As a professional tile backer board supplier, our Cement Coated XPS Board delivers high performance as an integrated building panel, specifically optimized for modern wet-area construction and thermal insulation works. Firstly, It adopts a unique structural design with a rigid closed-cell XPS foam core, reinforced fiberglass mesh and premium cement coating. For this reason, the Cement Coated XPS Board naturally combines outstanding waterproof performance, reliable thermal insulation capacity and solid structural strength in one single panel.
To begin with, its professional cement-coated surface significantly boosts tile adhesion and overall surface durability. As a result, this effectively stops tile hollowing, peeling and structural cracking during long-term service. Meanwhile, the high-density XPS foam core equips the Cement Coated XPS Board with ultra-low water absorption and superior moisture resistance, so it completely resists wall dampness and mold growth. Apart from waterproof performance, it maintains stable low thermal conductivity. Thus, it provides consistent thermal insulation and matches underfloor heating systems perfectly to cut down overall energy consumption.
In addition, the Cement Coated XPS Board features a lightweight, rigid and impact-resistant body, which brings great construction convenience. Specifically, it allows workers to cut, carry and install the panel on site with ease, which greatly saves construction time and reduces labor costs. Beyond that, it contains no fluorine or bromine materials and fully complies with international environmental standards. Ultimately, thanks to its customizable size and versatile performance, it acts as a premium all-in-one tiling substrate for bathrooms, shower rooms, kitchens, spas and caravan flooring, covering diverse global residential and commercial decoration projects.
