Understanding Scandinavian Thermally Modified Wood
Scandinavian Thermally Modified Wood is a Nordic softwood selection that undergoes a heat and steam treatment process. This modification improves the wood's dimensional stability without the use of chemical preservatives. The process results in a material with an expressive grain and a warm, natural color, suitable for both interior and exterior applications.
Its enhanced stability makes it a candidate for outdoor features where traditional softwoods might be more prone to warping or movement when exposed to varying weather conditions. The chemical-free modification process is a key benefit for those seeking a more natural material choice for their outdoor living spaces. While the modification enhances stability, all wood exposed to the elements will experience some degree of weathering and color change over time, typically mellowing to a silver-gray if left unfinished.
Profiles and Their Application in Privacy Screens
Scandinavian Thermally Modified Wood is available in several profiles, each offering a different aesthetic and application suitability. For privacy screens, the choice of profile will influence the visual texture, light filtration, and overall design of the screen.
Common profiles include:
The gap allows for some air and light passage while maintaining privacy.
Fluted #5 (1 × 6 nominal size): Featuring a ribbed or fluted surface, this profile adds architectural texture and depth. It can create interesting visual effects as light hits the screen throughout the day, offering a more contemporary aesthetic.
S4S E4E (5/4 × 6 nominal size): This profile is smooth on four sides and eased on four edges, providing a versatile, clean-lined board. It can be used for a solid screen or spaced to create varying degrees of openness. Its thickness (5/4) may offer additional robustness for certain screen designs.
When selecting a profile, consider the desired level of visual privacy, the amount of light and air you wish to pass through, and the overall architectural style of your outdoor space. The 'Interior to exterior' benefit of this wood allows for a cohesive design if you are also using it on adjacent walls or ceilings.
Design Considerations for a Privacy Screen
Designing a privacy screen with Scandinavian Thermally Modified Wood involves more than just selecting the boards. Careful planning of the screen's structure, dimensions, and integration with the surrounding environment is essential.
Structure and Support: A privacy screen is a non-structural element, but it requires a robust support system to withstand environmental forces, particularly wind. The design of the posts, framing, and fastening methods must be engineered to securely hold the wood panels. Local building codes may have specific requirements for freestanding structures or those attached to existing buildings.
Orientation and Spacing: The orientation of the wood boards (horizontal or vertical) and their spacing will significantly impact the screen's appearance and function. Horizontal boards can create a sense of width, while vertical boards can emphasize height. Varying the spacing between boards can adjust the level of privacy and light penetration.
Finish and Maintenance: While Scandinavian Thermally Modified Wood is inherently durable due to the thermal modification process, applying a finish can help maintain its original color longer and provide additional protection against UV rays and moisture. If left unfinished, the wood will naturally weather to a silver-gray patina over time. Regular cleaning is recommended to remove dirt and mildew and preserve the wood's appearance.
Worked Example: Material Takeoff for a Privacy Screen
Let's consider a hypothetical privacy screen project: a freestanding screen, 8 feet long and 6 feet high, intended to partially block a view. We'll assume a practical coverage width of 5.5 inches per board, allowing for the joint.
Screen Dimensions: Length = 8 feet (96 inches), Height = 6 feet (72 inches)
For a horizontal board layout, where boards run along the 8-foot length:
Number of boards needed vertically: Screen Height / Board Coverage Width = 72 inches / 5.5 inches per board = 13.09. Round up to 14 boards.
Each board needs to be 8 feet long. Therefore, we need 14 boards, each 8 feet in length.
Total Linear Footage: 14 boards × 8 feet/board = 112 linear feet.
If boards are typically sold in standard lengths (e.g., 8, 10, 12, 16 feet), you would purchase the most efficient lengths. For 112 linear feet, you might purchase fourteen 8-foot boards or a combination like eleven 10-foot boards (110 linear feet, requiring two small additional pieces) or seven 16-foot boards (112 linear feet, with less cutting and fewer end joints). Always account for potential waste from cuts and select the next full board length.
This calculation is for the wood boards only. Additional materials for the support structure (posts, framing, fasteners) would need to be calculated separately based on the chosen design and engineering requirements.
This example assumes no spacing between boards beyond the inherent nickel gap. If additional spacing is desired, the number of boards would decrease, and the overall appearance would change.

Questions to help you decide
Can Scandinavian Thermally Modified Wood be painted or stained?
Yes, Scandinavian Thermally Modified Wood can be painted or stained. Applying a finish can help maintain its original color, protect it from UV exposure, and provide additional moisture resistance. If left unfinished, the wood will naturally weather to a silver-gray patina over time. Always use exterior-grade paints or stains formulated for wood, and follow the manufacturer's application instructions.
How does thermal modification improve the wood for outdoor use?
Thermal modification involves heating the wood to high temperatures in a controlled environment, often with steam. This process alters the wood's cellular structure, reducing its ability to absorb moisture. This reduction in moisture absorption leads to significantly improved dimensional stability, meaning the wood is less prone to warping, swelling, or shrinking when exposed to changes in humidity and temperature. It also enhances the wood's resistance to decay, making it more suitable for outdoor applications without chemical preservatives.
What kind of maintenance is required for a Scandinavian Thermally Modified Wood privacy screen?
Maintenance for a Scandinavian Thermally Modified Wood privacy screen depends on whether it's finished or left natural. If unfinished, periodic cleaning to remove dirt, mildew, and other debris is generally sufficient. If a finish is applied, maintenance will involve cleaning and re-applying the finish according to the product manufacturer's recommendations, typically every few years, to preserve its appearance and protective qualities. Regular inspection for any structural issues or loose fasteners is also advised for any outdoor wood structure.
