Larch is considered to be the best material as a decking. It resembles the characteristics of oak, the same strong, dense, durable and resistant to all kinds of effects. No wonder it is used as a terrace board, because this structure is subject to the constant influence of weather, human and other factors. Nowadays, wood is processed in various ways. Especially for terraces and verandas, boards were used, the profile of which is covered with a small hem.
Thanks to this, shoes will not slide in rainy weather. This profile has the name of a terrace board "Velvet". In the common people it is called "anti-slip". Let's learn more in detail the characteristics and features of this material, the raw material for which is usually larch.
Terrace, as an element of architecture
The correct landscape design of a private house includes not only a flower bed, lawn, gazebo or garden, but also a cozy terrace or veranda. It will give the territory a complete view, and you will get a convenient place where you can spend evenings with your relatives, have dinner, fry meat, etc.
And the main point in creating such a terrace is a quality material that will withstand the load, constant walking and atmospheric influence. These include:
- temperature differences;
- influence of UV rays;
- low temperature in winter.
And in all cases the floor on the terrace is made of wood. It is obvious that the cement slab, stone or bitumen here will be inappropriate. The tree is not only beautifully externally, but also environmentally friendly, it will not burn your feet when the sun is strong. And if before the boards for the terrace were short-lived, the flooring that is done today, can last for many years. Larch is an example.
The terrace board made of larch "Velvet" won the hearts of many owners of open terraces. Why? Let's find out.
Features of larch
Larch is a coniferous tree species that does not lose its popularity. On piles of larch stands St. Petersburg and Venice. And this already says a lot. It is noteworthy that the larch resists the fungus, weakly rot, is not curved and it is not spoiled by insects. Thanks to these factors decking of larch for terraces has become one of the best. And thanks to the "Velvet" type a, the material does not slip, and moisture does not accumulate on the surface, draining along the grooves. Why "Velvet"? Look at the photo of a similar terrace board. Outwardly it resembles corduroy fabric. Therefore, this name.
It should be noted that larch has an amazing property - temperature stability. And this means that it is not afraid of temperature changes, ranging from -50 to +50 ℃. The material will not crack, and the splinter, standing barefoot on a corduroy board, you do not pick up. And thanks to the phytoncids, which stand out by the boards, the air is filled with a barely perceptible smell, which has a beneficial effect on you.
Characteristics of corduroy larch
First of all, let's look at the dimensions of the products. The boards can have a section of 20, 27, 32 and 45 mm. As for the width, it is in the range of 90-140 mm. However, the standard or running size is considered to be 140x127 mm.
If we talk about the length of the corduroy board, then it is very different. There are planks 1.65 m long, and there are 4 m. Everything depends on the needs of the customer. The interval in sizes is 0.5 m. The price for the board for the terrace is determined from the section, the amount of moisture, grade and width.
By the standard, it is possible to distinguish 4 varieties of a board from a larch. Each grade is characterized by the state of the surface of the boards from the front side. As for the physical qualities of varieties, they do not differ.
The highest class of corduroy wood is the "Extra" class. This means that on the front side there are no knots, resinous spots, blue and heart-shaped bands. All boards are like picking, although small scratches and cracks can be. But the reverse side is not controlled.
But the list and characteristics of other varieties:
- Variety "C". One of the cheapest. There may be mechanical damage (2 pcs per 1 m - this is the norm). Will not do without holes from the knots (1 piece per 1 m). Other surface defects are not controlled, so do not be surprised that the material will have them. Everything is determined by the price, which reaches 11-14 y. e. per 1 m2.
- Grade "B". The option is better. Here, stains, fibrousness, stripes of resin and holes from knots are no longer tolerated. As for mechanical defects, only 1 piece is allowed per meter. In a limited quantity, the larch board will have cracks, a core and knots. Per 1 m2 you have to pay 16 to 19 y. e.
- Grade "A". Blue is absent, as are the core strips, holes from knots, resinous spots, strips and unplaned areas. Within the limits of normal resin pockets, small cracks and scratches. The cost is from 20 to 29 USD. e.
"Velvet" boards have an advantage over smooth ones. After all, due to the furrows it will be more difficult to slip, and rain water will not accumulate on the surface. Thanks to this tree will not rot, and you will not step into a puddle.
If you are thinking over what material to make your terrace from, be sure that larch is an ideal option. Still, if you can not afford it, then use another material. Only here in priority should be a corduroy profile, which better tolerates the influence of the atmosphere and is more convenient for the owner.
