Kauri, Rimu & Matai T&G flooring like all timber flooring is a natural product. As such changes in temperature and ambient moisture levels will result in some movement of the boards. Our boards are delivered to site with a moisture content between 9 to 14%.
There are several factors that will promote movement of the boards. Firstly wider boards will experience a higher degree of shrinkage. Floor to ceiling windows can allow high temperatures and rapid shrinkage of the boards. In home heating and air-conditioning systems also promote rapid variations in moisture levels. An important factor to consider is ventilation under the floor. High moisture content under the floor will promote swelling of the boards.
If considering overlaying timber floors on concrete it is important to ensure the concrete is dry. Laid in winter the slab may take months to dry to an acceptable humidity level. When planning to lay solid timber overlay flooring on concrete a narrower board is recommended.
Your timber flooring should be transported and stored on site in dry conditions. We recommend acclimatizing the boards, strip stacked in the room where it is to be laid between one to three weeks. Do not acclimatize the timber flooring in direct contact with your concrete slab.
Your floorlayer will check the moisture content prior to laying. Please call us if you need us to refer you to experienced timber floor layers.
