  1. Производство изделий из дерева и обработку древесины можно подразделить на следующие виды работ: лесозаготовку, мебельную промышленность и производство древесной массы, целлюлозы, бумаги и картона, а также изделий из бумаги и картона.

  2. Процесс заготовки древесины начинается с отбора участка для лесоповала; затем производится лесопиление и распиловка поваленных деревьев на брёвна.

  3. На лесопильных предприятиях производится начальная стадия переработки брёвен в пиломатериалы, которая выполняется с помощью циркулярных или ленточных станков.

  4. Однако кроме пиления применяются и другие способы обработки бревён, в числе которых можно назвать фрезерование, лущение, строгание, точение, сверление и шлифование.

  5. Дерево – это экологически чистый, натуральный материал, который не выделяет вредных токсичных веществ при нагревании.

  6. Высокий показатель прочности и низкий коэффициент теплопроводности делают деревянный дом самым теплым.

  7. Строительство домов из дерева не подвержено сезонности, в то время как кирпичные и бетонные дома в зимний период не сроятся.

WOOD vs. BRICK HOUSE

Choosing the right material for building or renovating a house is the cornerstone of comfort, quality and design. Both brick and wood are beautiful and practical choices for homes. They also come in a variety of colors, finishes, treatments and styles. They are natural looking, durable and insulate well.

Location.Brick and wood are suitable for both city and country residences. Brick works well in cold climates. It retains natural heat and stays warm a long time. Brick protects well against storms and is a reliable option where storms are a threat. Wood is more convenient and appropriate in remote settings, in vales (where erosion and silt accumulation can damage brick walls) and where wood is widely available. Wood is relatively light compared to brick and more flexible.

Purpose.Many varieties of brick are guaranteed to last for one or two lifetimes. However, brick is marginally more expensive than wood. Wood is biodegradable, affordable, healthy and safe. Wood homes are easier to renovate, alter and build than brick. Thick, rot-treated logs can last up to one hundred years or more. Hardwoods and older trees are strong and durable.

Advantages.Brick has several advantages in addition to weatherproofing, heat and property value. It is fireproof, termite resistant and energy efficient. Brick is incredibly stable. It requires no maintenance. Wood also insulates well and is safe. Its flexibility, variety and natural properties make it easy to work with. Some woods are thought to release terpenes, a substance that soothes the mind and body ("forest bath effect"). Wood is also a natural air conditioner and absorbs humidity.

Disadvantages.Poorly made bricks such as clinkers and older recycled bricks might be pitted, irregularly shaped, worn or prone to chipping. In damp or humid climates, porous brick invites mold. It suffers damage as water and ice expand and contract in its pores. Wood is vulnerable to natural disasters such as fire, infestations of termites and decomposition through rot. Wood is susceptible to cracking when soaked.

Upkeep.Both wood and brick are easy to clean, and a simple wash or spray should do the trick. Again, quality brick is resistant to damage. In case of accidents, small pieces can be conveniently changed or replaced. Older or badly fired brick can require patching or new mortar. Wood might require occasional treatment, refinishing or replacement. Cracks should be filled as they appear or before rainy or snowy seasons. Natural fillers such as pitch made from sap, mud, sand or moss can be used.
