Because Mataverde+ Hem-Fir uses the upper grades of Western Hemlock ("A+ better" and "C+ Better" grades) and vertical grain boards, the product not only performs better but is absolutely beautiful as well. Mataverde+ thermally modified Hem Fir has the great looks you would expect to find in Western Red Cedar at a far more affordable price. ![Thermawood Hemlock diagonal and vertical rainscreen Climate-Shield](https://www.mataverdedecking.com/hs-fs/hubfs/Thermawood%20Hemlock%20diagonal%20and%20vertical%20rainscreen.jpeg?width=973&height=689&name=Thermawood%20Hemlock%20diagonal%20and%20vertical%20rainscreen.jpeg)   ## Why Use Mataverde+ Thermally Modified Hem-Fir Wood Rainscreen Cladding and Siding?

[DOWNLOAD MATAVERDE THERMAWOOD HEM-FIR CARE AND MAINTENANCE GUIDELINES HERE](https://www.mataverdedecking.com/hubfs/Mataverde%20Therma%20Wood%20Decking%20Installation,%20Care%20and%20Maintenance%20Guidelines.pdf) Mataverde thermally modified hemlock siding requires no maintenance beyond normal cleaning. Thermally modified cladding is easy to care for and there are appearance options, including oil finishes and a low maintenance option, where you can allow your deck to weather to a gray driftwood look. Thermally modified siding is real wood, but it performs so well, it can be finished or allowed to weather. Thermawood rainscreen wood siding has a rich natural brown beauty that can be enhanced with a natural oil finish (like Penofin) or it can be allowed to "weather out" to a natural silvery patina.  Whether you prefer to maintain the 'like new' wood look, or the silvery look, the choice is yours.  For more information about your finish options, [DOWNLOAD "HOW WOODS WEATHER GUIDE"](https://www.mataverdedecking.com/download-guide-how-woods-weather).  --- [**DOWNLOAD MATAVERDE THERMAWOOD HEM FIR BROCHURE**](https://www.mataverdedecking.com/hubfs/Mataverde%20THERMAWOOD%20HEM%20FIR%20Brochure.pdf) ---   ### Other Wood Siding Species Options and Comparisons Want to see some incredible projects?
