You can clearly see that the cut board in the cross section has the shape of a regular rectangle. This fact distinguishes it from an uncut board. Due to such an important feature, it can be stacked evenly, properly packaged and the volume of packaged materials determined. If it will be necessary to determine how much the cube of the board weighs, it will be enough to multiply the density and volume. It should be noted that the density is a reference value, which depends on both the wood species and its moisture content.
What effect does moisture have on the weight of wood?
Humidity has a direct effect on the weight of lumber and other wood products. As you know, it is measured by the percentage of the mass of water in wood to the mass of dry wood. It should be noted that humidity also depends on the drying conditions, its duration and is divided into the following degrees:
- Dry - wood that has necessarily undergone technological drying and has a moisture content of 10% to 18%.
- Air-dry - wood with uniform humidity from 19% to 23%, the degree of which can be achieved if the wood is stored in natural conditions.
- Raw - wood with a moisture content of 24% to 45%, which is in the drying stage.
- Freshly chopped and wet - wood with a moisture content of more than 45%, only chopped or located in water for a long time.
It should be noted that the indicator of the weight of wood is not always the same. Therefore, how much a cube of a board weighs depends, first of all, on such a parameter as wood moisture. If we take oak and birch as an example, we can see that a cubic meter of oak has a weight of 700 kg, and birch - about 600 kg. However, it can be vice versa, that is, the value of birch will be greater than oak. Such indicators take place, because in this case the moisture content of wood is of no small importance. Based on the categories of humidity, it can be said, despite the same humidity, each wood species has its own weight.
The effect of density on the weight category
Density is another important factor affecting the weight of wood. As a rule, iron and ebony have the highest density, the indicators of which vary from 1100 kg / m3 to 1350 kg / m3. Closer figures can be presented by boxwood and bog oak - from 950 kg / m3 to 1100 kg / m3. Before calculating how much a cube weighs of oak, beech, pear or hornbeam, its density, which is approximately 700 kg / m3, should be taken into account. The lowest density is distinguished by pine and bamboo - 500 kg / m3, well, and the smallest indicator has a cork tree - 140 kg / m3.
Why do you need to know the weight of a cubic meter of wood?
To know how much a cube of a natural moisture board weighs is sometimes very necessary. Indeed, acquiring building material, it is quite problematic for a simple person to visually determine the required amount. If you have knowledge in this area, for example, the dimensions of the beam, the corresponding material and moisture indicator, then calculating the weight of the purchased goods will not be such a difficult task.
If you can’t determine how much the cube of the board weighs, it is recommended that you contact the seller for help, who will help you correctly calculate the right amount.
Wood heat transfer
There is another indicator that allows you to easily determine, for example, how much a cube of dry pine boards weighs. This parameter is heat transfer. The indicator is of no small importance for those people who use wood as a heating material. It should be noted that thermal conductivity directly depends on the density of the tree species. And the higher the hardness, the higher the thermal conductivity.
Of course, no one will use boxwood as a heating material. However, when choosing between pine or birch, it will be possible to get much more heat if you know which of the species is the hardest. According to the reference tables, you can find out information about the density of each tree.
So, starting building a house, you have to deal with nuances that at first glance seem insignificant. However, not all so simple. There are certain indicators that must be taken into account when choosing wood, so as not to make a mistake with the choice and get the desired result from the plan.
