Untreated

Platowood wood can be applied untreated. Due to its high durability class, it does not require a finish for outdoor applications. An untreated application not only saves time and costs, it is also environmentally friendly. Without a finish, Platowood wood will grey evenly.

Window and frame wood

Platowood Fraké can be used untreated as window and frame wood, unlike many hardwood alternatives. This means it does not need to be coated, resulting in a natural and warm appearance. This application also provides insulation and burglary resistance. For more information about the benefits, visit the window and frame wood page.

Raw and untreated

Some architects, such as Francois Verhoeven, take it a step further. They use Platowood wood in its raw form—untreated and without a planed profile. This gives a façade a robust and natural appearance, as seen at Villa K2.

Frequently asked
questions

For indoor use, a high durability class isn't necessary, but there are still good reasons to use Platowood wood indoors. First, it has a beautiful brown color without any paint finish, and second, it is highly dimensionally stable—so you can be sure the wood will hardly move even when humidity levels in the building fluctuate.

When the window frame or door is evenly exposed to sunlight, the weathering will also be uniform. To prevent uneven greying, you can choose to treat your frame with a pre-weathering stain.

Keep in mind that if you apply Platowood window frame wood untreated, the wood behind the glass will not grey as evenly as the exterior. Glass blocks UV rays, which influence the greying process of the wood.

Standard Platowood has a fire class of D-s2, d0. With the FireProtect treatment, this is upgraded to B-s2, d0. The exact fire class may vary depending on the wood type, treatment, and application.
