Construction ceiling tile

Lift a ceiling tile and examine the plenum for potential problems. Walls or full-height partitions that extend to the floor above can obstruct or divert air movement in ceiling plenums unless transfer grilles have been provided. If fire dampers have been installed to allow air circulation through walls or partitions, confirm that the dampers are open. Construction debris and damaged or loose material in the plenum area may become covered with dust and can release particles and fibers. 

A large number of studies have also been done to investigate the lifetime of HC1 in a fire atmosphere [20-24]. These studies have shown that HC1 reacts very rapidly with most common construction surfaces (cement block, ceiling tile, gypsum board, etc.) so that the peak atmospheric concentration found in a fire is much less than would have been predicted from the chlorine content of the burning material. Furthermore, this peak concentration soon decreases and HC1 disappears completely from the atmosphere. 

In other unpublished work by CSIRO s laboratory, emissions were evaluated from an electric heater panel that was designed to replace office ceiling tiles. Specific construction details were unknown other than that the panel exterior was powder-coated steel. Emissions were dominated by 1-butanol and it was assumed that this originated from the powder coating, as may be the case with the oven above.

In order to minimize the risk of microbiological contamination, surfaces must be clean and therefore smooth and accessible. Walls are often tiled or painted while floors are of asphalt, terrazo, or other suitable material. There must be a sufficient fall to the floor to permit efficient drainage. The drains themselves must be well constructed so that they are easy to maintain and trap all odours. Ceilings are so designed that condensation does not fall into the body of the room. Alternatively, air conditioning should ensure that no condensation forms. 

Asbestos is a mineral found in many rock formations. When separated it becomes a fluffy, fibrous material with many uses. It was used extensively in the construction industry during the 1960s and 1970s for roofing material, ceiling and floor tiles, fire-resistant board for doors and partitions, for thermal insulation and commercial and industrial pipe lagging. 

Acoustical tile n. An acoustical material in board form, usually having unit dimensions of 24 in. X 24 in. (approx. 61cm X 61 cm) or less. Usually used on ceilings but also may be applied to sidewalls. Harris CM (2005) Dictionary of architecture and construction. McGraw-Hill Co., New York. 

Carpenters are construction workers. Most carpenters work in building sites, but these craftsmen (very few of them are women) also work in tunnel work sites, mines, bridge-building sites and in shipyards. Some carpenters work in plants manufacturing prefabricated building units and houses. Construction carpenters build wooden forms for concrete, mount wall frames, put up roof frames, install insulation, panel walls and ceilings, install doors and window frames, put-up acoustic tiles, lay wooden floor panels and install cabins. Some specialisation into different job tasks is possible. 

Interior finish is defined as those materials that make up the exposed interior surface of wall, ceiling, and floor constructions. The common interior-finish materials are wood, plywood, plaster, wallboards, acoustical tile, insulating and decorative finishes, plastics, and various wad coverings. 

Lath lath a/so laA n [ME, fr. (ass.) OE Icethth- akin to OHGr latta lath, Welsh Uath yard] (13c) One of a number of thin narrow strips of wood nailed to rafters, ceiling joists, wall studs, etc., to make a groundwork or key for slates, tiles or plastering.

Adhesives for ceramic tiles are specified by the standard EN 12004 2007 (Adhesives for tiles. Requirements, evaluation of conformity, classification, and designation), and includes performance requirements for cementitious, dispersion, and reaction resin adhesive types for all internal and/or external wall, floor and ceiling applications. Annex ZA, of this standard, sets out the requirements, which address the provisions of the Construction Products Directive (see O Sect. 35.4 below), and include assessments of durability. Compliance with these requirements confers a presumption of fitness for purpose for the applications and form part of a CE mark. In these cases durability is assessed by elevated temperature and/or water immersion accelerated ageing or freeze-thaw cycling of test specimens and then determining tensile or shear adhesion strength against minimum requirements.
