Overview of the best methods for fixing thermally modified wood to facades

Thermally modified wood is a durable, environmentally friendly and aesthetically pleasing material that is widely used in facade finishing. Thanks to thermal treatment, such wood has high resistance to moisture, biodeterioration and temperature changes. However, it is important not only to choose a quality material, but also to install it correctly. In this article, we will look at the best ways to fix thermally modified wood to a facade, analyze popular types of fasteners for wood, and also tell you how to choose fasteners for thermally modified wood to maintain the durability and appearance of the structure.

Main methods for fixing thermally modified wood

There are several common options for installing thermally modified boards on a facade. Each of them has its own advantages, is suitable for different operating conditions and affects the final appearance of the finish.

1. Open fastening

One of the simplest and most accessible methods. Thermally modified boards are attached to the sheathing using wood screws, nails or screws. This is a quick and inexpensive method, but the fasteners remain visible.

Pros:

• Ease of installation;

• Availability of fasteners;

• High reliability of the connection.

Cons:

• Visible fasteners can worsen the appearance of the facade;

• There is a risk of cracks if the screws are screwed in incorrectly.

Use only anti-corrosion wood screws with a countersunk head - this will minimize the risk of rust and increase the service life of the finish.

2. Hidden fastening

This is a modern and aesthetic option, in which thermally modified wood is fastened from the back of the board or in the side grooves. Special clamps, staples or systems with a lock are used.

Advantages:

• Perfectly smooth appearance of the facade;

• No visible traces of fasteners;

• Minimal risk of damage to the wood.

Disadvantages:

• Complexity of installation;

• Higher cost of fasteners and work;

• Requires precision and accuracy.

What types of wood fasteners are there: popular types

Various types of wood fasteners are used to install thermally modified wood on a facade, including:

• Self-tapping screws for wood are a classic. They are suitable for open installation.

• Clamps are used for hidden installation. They are fixed to the lathing and hold the thermally modified board by the groove.

• Nails with an anti-corrosion coating are applicable for finishing in budget projects, they require accuracy.

• Studs and anchors are used in specific architectural solutions and when installing on a solid base.

• Mounting clips are a modern method of hidden fastening, they provide strength and a uniform gap.

How to choose fasteners for thermally modified wood

When choosing, it is important to consider the following parameters:

• Fastener material - stainless steel or galvanized steel. They are not subject to corrosion.

• Mounting method - if you need a hidden facade, choose clamps or clips.

• Thickness and type of board - for thin thermally modified wood, it is better to use soft fasteners without the risk of cracking.

• Operating conditions - for coastal or humid areas, the most stable fasteners are important.

• Type of lathing - fastening on wood and metal requires a different approach.

The correct choice of fasteners for wood is the basis for the durability and aesthetics of a facade made of thermally modified wood. Regardless of whether you choose open or hidden fastening of thermally modified wood, it is important to use high-quality materials and follow the installation technology. This is the only way to create a reliable and beautiful facade that will last for decades without losing its appearance.

If you are planning to finish the facade, be sure to study the types of fasteners for wood and choose a method of fastening thermally modified wood that is suitable for your project.
