In the world of modern construction, where durability, energy efficiency, and ease of installation are non-negotiable, Feininger XPS Backer Board stands out as a game-changer. Designed specifically to meet the rigorous demands of residential and commercial projects, this extruded polystyrene (XPS) solution redefines what a high-performance backer board can deliver—whether for exterior cladding, tile underlayment, or insulation applications.

Why Feininger XPS Backer Board Outperforms the Rest

Feininger doesn’t just follow industry standards; it sets them. Our XPS backer board is engineered with three core advantages that make it the top pick for contractors, architects, and builders worldwide:

1. Unmatched Moisture Resistance: No More Mold or Rot

Unlike traditional cement backer boards or fiber cement alternatives, Feininger XPS is inherently water-impermeable. Its closed-cell structure blocks moisture absorption entirely, even in high-humidity areas like bathrooms, kitchens, or exterior walls exposed to rain and snow. This means zero risk of mold growth, warping, or structural degradation over time—saving you from costly repairs and ensuring long-term building integrity.

2. Superior Insulation: Cut Energy Costs, Boost Comfort

As an XPS-based product, Feininger’s backer board delivers exceptional thermal performance with a high R-value (thermal resistance). It acts as a continuous insulation barrier, reducing heat transfer through walls, floors, or tile installations. For homeowners, this translates to lower heating and cooling bills; for commercial projects, it means meeting strict energy codes (such as LEED or ENERGY STAR) with ease.

3. Lightweight & Easy to Install: Save Time, Reduce Labor Costs

Contractors love Feininger XPS Backer Board for its practicality. At just a fraction of the weight of cement boards, it’s easy to transport, cut (with standard tools like a utility knife), and fasten—no heavy equipment or specialized skills required. This slashes installation time by up to 30% compared to traditional materials, helping projects stay on schedule and under budget.

Versatile Applications: Built for Every Project

Feininger XPS Backer Board isn’t limited to one use—it adapts to diverse construction needs, making it a versatile addition to any job site:

• Exterior Cladding Backing: Provides a stable, moisture-resistant base for vinyl, fiber cement, or stone cladding, preventing water damage to the building envelope.

• Tile & Stone Underlayment: Ideal for floors, showers, and backsplashes—its rigid structure prevents tile cracking and ensures even load distribution.

• Continuous Insulation: Works seamlessly with wall assemblies to eliminate thermal bridges, enhancing overall building energy efficiency.

• Roofing Accessories: Used as a rigid base for roof membranes or as insulation in parapet walls, standing up to extreme temperatures and weather.

Feininger’s Commitment to Quality & Sustainability

We believe high performance shouldn’t come at the cost of the planet. Feininger XPS Backer Board is:

• Durable: Engineered to resist shrinkage, warping, and impact, ensuring a lifespan that matches the building itself.

• Eco-Friendly: Manufactured with low-VOC (volatile organic compound) materials and is 100% recyclable, aligning with global sustainability goals.

• Certified: Meets or exceeds international standards (such as ASTM C578 for XPS insulation and ANSI A118.9 for backer boards), giving you peace of mind in every installation.
