Safe, efficient high-temperature insulation for residential fireplaces, wood burning stoves, pizza ovens, saunas, and masonry heaters. A1 non-combustible, asbestos-free, easy to install for DIY projects and professional installations.
Building a wood burning fireplace, pizza oven, or sauna requires materials that can withstand direct flame contact and sustained high temperatures while remaining completely safe inside your home. Traditional firebricks are heavy and hard to work with, while modern ceramic fiber boards can release fibers over time.
HR RHINO calcium silicate boards are the preferred modern solution for residential fireplaces and heating applications. Our boards offer 1100°C heat resistance, A1 non-combustible classification, lightweight handling, and easy installation — you can cut them with ordinary woodworking tools and install them with standard masonry adhesive.
Whether you are a homeowner, DIY enthusiast, wood stove dealer, fireplace installer, or pizza oven builder, our boards deliver safe, reliable, long-lasting performance. 100% asbestos-free and non-toxic — safe for your family, your guests, and your home.
Six residential and hospitality applications where HR RHINO calcium silicate boards deliver safe, efficient, long-lasting performance.
Line the firebox of wood burning fireplaces to reflect heat into the room while protecting surrounding walls. Works as replacement for traditional firebrick with better insulation performance and easier installation.
Create safe wall and floor protection when installing wood burning stoves. Our boards meet fire code clearance requirements when properly installed between the stove and combustible surfaces.
Build professional-quality wood-fired pizza ovens with calcium silicate insulation for the dome exterior and base. Retains heat for consistent cooking temperature while keeping exterior surfaces cool.
Safe heat shielding around sauna heaters and walls. Protects surrounding walls from high temperatures while providing efficient heat retention inside the sauna room. Perfect for residential and commercial saunas.
Line chimneys and flue connectors to maintain optimal draft and protect surrounding structures. Excellent alternative to traditional ceramic chimney liners with better thermal performance.
European-style masonry heaters (kachelofen) and traditional tile stoves benefit from calcium silicate boards for the combustion chamber insulation. Provides controlled heat release for hours of radiant warmth.
Everything you need in a residential heat shield material.
Withstands direct flame contact and maximum wood fire temperatures. Perfect for firebox linings, pizza oven domes, and sauna heater surrounds.
100% asbestos-free and non-toxic. No harmful fibers released. Safe for family, pets, and indoor air quality in bedrooms, living rooms, and kitchens.
