Laying Solid Timber Flooring: A Comprehensive Guide
Natural timber flooring is an elegant and timeless choice for any home or commercial space. With its warm tones, unique grain patterns, and durability, it brings a sense of nature indoors. However, proper installation is key to ensuring the longevity and performance of timber flooring. Below, we’ll cover three critical aspects of laying natural timber flooring: acclimatising the timber on site, leaving a 10mm gap around the perimeter, and incorporating movement control joints.
Acclimatize the Timber on Site
One of the most important steps before laying natural timber flooring is to acclimatize the timber to the environment in which it will be installed. Timber is a natural material that expands and contracts with changes in humidity and temperature. If the flooring is not properly acclimatized, it may warp, cup, or buckle after installation.
How to Acclimatize Timber Flooring:
- Storage: Stack the timber boards in the room where they will be installed, ensuring they are off the ground and there is enough airflow around the stack. This allows the timber to gradually adjust to the room's humidity and temperature.
- Time Frame: Acclimatization typically takes between 5 to 14 days, depending on the timber species, climate, and the room’s conditions. Refer to the manufacturer’s guidelines for specific recommendations.
- Monitor Conditions: Keep the room well-ventilated and monitor the temperature and humidity levels during this period to ensure a stable environment.
By allowing the timber to acclimatize, you minimize the risk of issues post-installation, such as gaps between boards or uneven surfaces.
The timber boards should be checked using a moisture meter before laying and ideally have a reading of 9-11% moisture content.
Leave a 10mm Gap Around the Perimeter
Timber flooring is dynamic; it expands and contracts as environmental conditions change. To accommodate this natural movement, it's essential to leave a 10mm expansion gap around the perimeter of each room. This gap prevents the timber from pressing against walls or other fixed structures, which could lead to buckling or lifting.
Why a 10mm Gap is Important:
- Room for Expansion: The gap gives the timber room to expand without causing damage to the flooring or the surrounding structures.
- Concealment: This gap is typically concealed by skirting boards, so it doesn’t affect the aesthetic of the finished floor.
- Consistency: Ensure the gap is consistent around all edges of the room, including at doorways and against fixed objects like columns or kitchen islands.
Leaving this expansion gap is a simple yet crucial step that protects the integrity of your timber flooring over time.
Incorporate Movement Control Joints
In larger spaces, or where the flooring spans multiple rooms, it’s essential to incorporate movement control joints. These joints are designed to manage the natural expansion and contraction of the timber over larger areas, preventing damage or uneven wear.
Where and How to Incorporate Movement Control Joints:
- Large Areas: For large continuous areas of flooring, consider installing a movement control joint every 8 to 10 meters, depending on the type of timber and expected environmental conditions.
- Transitions Between Rooms: Use control joints at doorways or transitions between rooms to account for differences in temperature and humidity across different spaces.
- Aesthetic Considerations: Movement control joints can be covered with T-moldings or other trim pieces that blend with the flooring, ensuring they do not detract from the overall look of the space.
By incorporating movement control joints, you allow the flooring to expand and contract naturally without compromising the structure or appearance of the floor.
Conclusion
Laying solid timber flooring is a rewarding process that, when done correctly, results in a beautiful and long-lasting surface. Remember to acclimatize the timber on site, leave a 10mm gap around the perimeter of each room, and incorporate movement control joints where necessary. By following these best practices, you ensure that your timber flooring will perform well for years to come, maintaining its beauty and functionality in any environment.
Investing time and effort in the installation process is key to enjoying the warmth and elegance of natural timber flooring for many years.
