Flush Door
A flush door has a basic structure composed of solid blockboard core, vertical stiles, and horizontal rails that create a pre-fixed frame. The blockboard is composed of wooden strips that are placed edge-to-edge and sandwiched between veneers, then bonded under high pressure and temperature using a synthetic resin. So in a simpler term, it is a door that is made of a timber frame covered with ply from both the sides and then the hollow part inside is filled with rectangular blocks of soft wood. Then a decorative finish is given by fixing veneer on the top. A flush door is so called because it has an entirely smooth surface. If water were to be splashed on its surface, it would simply flow off its surface without accumulating.
Chip Board
Particle board – also known as particleboard, low-density fibreboard (LDF), and chipboard – is an engineered wood product manufactured from wood chips, sawmill shavings, or even sawdust, and a synthetic resin or other suitable binder, which is pressed and extruded. Oriented strand board, also known as flakeboard, waferboard, or chipboard, is similar but uses machined wood flakes offering more strength. All of these are composite materials that belong to the spectrum of fiberboard products.Chipboard can also be used as a scrapbooking embellishment.High-grade chipboard can also be used to create lightweight furniture like tables, stools, benches and bookcases. This type of chipboard is covered in a veneer or laminates to make furniture, which can be less expensive than solid wood.
Chipboard, is made from wood chips, sawmill shavings, sawdust, and synthetic resin or other suitable binder, which is pressed and extruded. The factors which have contributed in influencing the market demand are its affordability, ease in installation, and high density and uniformity. In spite of its density, particle board is the lightest type of fibreboard and is less strong than even medium-density fibreboard.
Hardboard
Hardboard, also called high-density fiberboard, is a type of fiberboard, which is an engineered wood product. It is similar to particle board and medium-density fiberboard, but is denser and much stronger and harder because it is made out of exploded wood fibers that have been highly compressed.
Hardboard is a composite wood product used in construction and woodworking. It is typically sold in 4' by 8' (1.2 to 2.4 m) sheets, and can range from 1/4" to 1" (6.35 to 25.4 mm) in thickness. While it is similar in appearance to plywood or particleboard, hardboard is actually constructed quite differently from these products. It is made from fine wood fibers that are compacted under high levels of heat and pressure to form a very dense, hard wooden sheet. Due to the extreme heat and pressure levels, there is usually no need to use adhesives or binding agents to hold the wood fibers together.
Insulating Board
Insulating board: a board with insulating properties especially : a structural or finish material that consists of sheets of lightly compressed vegetable pulp variously finished and is used especially for its thermal insulating effect resulting from great numbers of minute included air spaces.
The global market for thermal insulation is benefitting from government-backed environmental regulations for conservation of energy in buildings. In particular, governments in cold countries are actively promoting zero energy loss buildings that can be attained by means of reliable thermal insulation materials. As per the analysis revealed by the institute for Energy Diversification and Saving (IDEA), thermal insulation improvements can account for up to 30% drop in heat and air conditioning consumption to translate into energy and money savings and reduction in CO2 emissions as well.
