Mataverde

Mataverde® is a premium exterior wood brand focused on high-performance siding, decking, and outdoor materials. Through Cambium, two of its flagship lines are available: SaferWood® fire-retardant treated Western Red Cedar for high-fire-risk zones, and Thermal Hemlock, a thermally modified wood built for stability and durability in any climate.

SaferWood is real Western Red Cedar treated with Thermex-FR®, a proprietary, non-toxic fire retardant, and offered in siding, decking, fencing, and posts. It carries a Class A fire rating, is classified as ignition resistant, and meets WUI and IWUI requirements, so projects in wildfire-prone areas can use genuine wood instead of fiber cement or composites.

No. Thermex-FR® is pressure-applied and bonds into the wood's cellular structure, creating permanent, full-depth protection. It won't leach out in rain or humidity, won't wash or flake off, and passed California's OSFM 10-year outdoor weathering test. The treatment is warranted for the life of the wood.

Thermal Hemlock is upper-grade Western Hemlock modified with heat and pressure in a vacuum kiln, with no chemicals or additives. The gentler, lower-temperature process avoids the brittleness common to thermally modified wood and earns a Class 1 durability rating, with rich warm brown tones, a Janka hardness of 540, and 20+ years of expected service outdoors.

SaferWood is the go-to for projects in WUI and high-fire-severity zones, from siding and soffits to decking, fencing, and ground-contact posts. Thermal Hemlock decking performs in all climates and suits backyard decks, rooftop decks, and commercial outdoor spaces. Both pair naturally with rainscreen assemblies like Climate-Shield®.

Both lines can be finished with an oil-based stain to hold their color, or left to weather naturally to a silver-gray patina. Maintenance is simple: an annual cleaning with a biodegradable cleaner, and optional refinishing if you prefer the like-new look. Avoid pressure washers and harsh chemicals.
