VaporTec™ XPS Building Panels – Ultra‑Lightweight, Waterproof Tile Backer Board

Engineered for modern tile installations in wet and dry areas alike, Vaportec™ XPS combines exceptional strength with minimal weight. Its innovative fiberglass-reinforced polymer-cement coating makes it stiffer, easier to cut, and more water-resistant than other backer boards—ideal for showers, kitchens, floors, ceilings, and underfloor heating systems.

Key Features:

• Feather‑weight yet rigid – weighs just ~0.27 lb./ft² at 5/32″ thickness (up to 0.56 lb./ft² at 3-1/8″)

• Waterproof & vapor-tight – closed-cell XPS core and sealed polymer‑cement coating prevent moisture absorption

• Thermally insulating – delivers R-values from 1.5 hr·ft²·°F/BTU (5/32″) up to 17.1 hr·ft²·°F/BTU (3.94″), helping reduce heating costs and ideal for underfloor warming.

• High compressive strength – endures up to 6,270 lb./ft² without permanent deformation, suitable for floors and load-bearing surfaces.

• Enhanced bonding surface – dual-sided glass fiber mesh embedded in cementitious polymer mortar offers a prime tile adhesive grip.

• Easy to trim & install – cuts clean with a utility knife or saw, lighter handling, and less dust; boards up to 3/8″ can be adhered, thicker boards can also be fixed mechanically.

• Eco‑friendly XPS core – free from HBCD, CFC, and HCFC, with zero ozone depletion potential and minimal global warming impact.

• Fire safety & durability – rated Class E fire resistance with vapor diffusion equivalent > 14.4 ft., making it suitable for humid and high-moisture environments.
