Towards the centre of the trunk, the wood gets less hard. The wood has a Janka ball hardness of 112.5 - 154.7 kgf/cm 2 (1600 – 2200 psi), which is greater than that of oak (70.3 - 84.4 kgf/cm 2) and Douglas fir (35.9 kgf/cm 2). Coconut timber is classified according to three degrees of density: High-density timber (dermal) – hard: 600–900 ...
Cladding can be made of any of a wide range of materials including wood, metal, brick, vinyl, and composite materials that can include aluminium, wood, blends of cement and recycled polystyrene, or wheat/rice straw fibres. [2] Materials used for cladding affect vulnerability to fire.
Siding or wall cladding is the protective material attached to the exterior side of a wall of a house or other building. Along with the roof, it forms the first line of defense against the elements, most importantly sun, rain/snow, heat and cold, thus creating a stable, more comfortable environment on the interior side.
Exterior insulation and finish system (EIFS) is a general class of non-load bearing building cladding systems that provides exterior walls with an insulated, water-resistant, finished surface in an integrated composite material system. EIFS has been in use since the 1960s in North America and was first used on masonry buildings.
Amakan, also known as sawali in the northern Philippines, is a type of traditional woven split-bamboo mats used as walls, paneling, or wall cladding in the Philippines. [1] They are woven into various intricate traditional patterns, often resulting in repeating diagonal, zigzag, or diamond-like shapes.
Shiplap is either rough-sawn 25 mm (1 in) or milled 19 mm (3 ⁄ 4 in) pine or similarly inexpensive wood between 76 and 254 mm (3 and 10 in) wide with a 9.5–12.7 mm (3 ⁄ 8 – 1 ⁄ 2 in) rabbet on opposite sides of each edge. [1] The rabbet allows the boards to overlap in this area.
Thermally modified wood is engineered wood that has been modified by a controlled pyrolysis process of wood being heated to (> 180 °C) in an oxygen free atmosphere. This process changes to the chemical structures of wood's cell wall components lignin , cellulose and hemicellulose which decreases its hygroscopy and thus increases dimensional ...
Xanthostemon verdugonianus is known to be the hardest Philippine hardwood species. Cutting a 70-cm thick tree with axes normally requires three hours, but cutting a Mangkono tree with the same diameter usually takes two to four days.
