MicroPro Sienna

What is MicroPro Sienna®?

Pressure treated with MicroPro Micronized Copper Azole (MCA), MicroPro Sienna® uses the most advanced preservative technology available in any wood used in residential application. The preservatives have been specially formulated for Canadian species and use, with iron oxide pigments added during pressure treatment to give the wood a warm, brown colour.

Sienna Brown Treated Wood

Not all browns are the same. Though most pressure treated wood can look green in colour, MicroPro Sienna® Treated Wood uses the most advanced preservative technology and features a warm natural brown tone, enhancing its grain and natural characteristics.

Products treated with the MicroPro Sienna® pigment colouring system have solid copper particles deposited into the wood to make it resistant to fading. Applying a water repellant to the wood as soon as it’s dry to the touch will help maintain its colour and surface as it may discolour over time due to varying exposure conditions and different wood species.

Fungal Decay & Termite Protection

Fungal Decay & Termite Protection

To protect the wood against fungal decay and termite attacks, MicroPro Sienna® Treated Wood products are pressure treated with MicroPro® Micronized Copper Azole (MCA). Copper, which has long been known as an effective wood preservative is the main ingredient in the preservative system. MicroPro Sienna® uses micronized copper coupled with micronized azole for long-term protection of wood exposed in exterior applications.
