Tin is a highly workable metal that was once as valuable as silver for jewelry, coins, and special dishware. Today it is used in sheets in the construction of buildings and roofs, for soldering or joining metal parts, for storage containers, and in alloys like bronze and Babbitt metal. 

This specification covers the composition and physical properties of insulating boards composed of wood-fiber insulation board laminated to rigid cellular polystyrene insulation boards, flat or tapered, used principally above structural roof decks for thermal insulation as well as for a base for roofing in building construction. 

Each building code has a list of specific conditions and requirements for the use of foamed plastics. Typically, these cover trim, masonry construction, cold storage buildings, metal faced building units, roofing applications, doors and exterior sheating.

To avoid deterioration of the bags by moisture and of the hydrated lime by re-carbonation, bagged hydrate should be stored under cover. The ideal store is a brick or concrete building constructed to minimise draughts. It should have a low roof to minimise internal air space and be unheated. Under such conditions, bagged hydrate can be stored for a year without significant deterioration [21.1]. 

In addition to their use on highways and roofs, both hot poured and room temperature hardening bituminous compositions have been used as caulking materials and sealants in building construction. The classical agphalt/ashestos sealants contained volatile solvents and their resistance to solvents was increased by the incorporation of coal tar. These sealants have also been modified by the addition of elastomers, such as powdered rubber, and fillers, such as sawdust.12... 

Copolymers of vinylidene fluoride with tetrafluoroethylene or hexafluoropropy-lene have recently been developed as an air-drying paint mainly for repair coating of the PVDF finish [2.19]-[2.21], Poly(vinylidene fluoride) is now widely used for coil coating of galvanized iron and aluminum sheets, and as a maintenance-free coating for walls of skyscraper buildings and roofing of industrial constructions. 

Already many lightweight membrane structures are in existence, and an increasing number of them are planned for the future, e.g. football stadium roofs. For such structures the combination of materials produces widely differing properties. Some projects are very cost-effective, while others are used for more expensive building constructions. Some constructions are of a temporary nature, some are erected at a fixed location some are required to be portable, while others may remain in place for decades. Textile roofs or walls may be open or closed according to the time of day or the position of the sun others stay fixed in one position. Some materials are required to have high translucency others may be designed for maximum insulation. 

As part of the discussion on the use of textile construction membranes, it should be made clear what happens at end-of-Ufe for materials used so far for building construction. Thermoplastic membrane components like PVC can be processed after each utilization period under certain conditions and be supplied for reuse in the raw material cycle. Leading European manufacturers of PVC/PES membranes and roofing sheets have united in order to recycle post-consumer waste, disused membranes and PVC materials (ref. Vinyl) in most modem plants with approved thermo-physical procedures. The output of this recycling process is then used for new products. An important factor in the operation of these and other environmental raw-material recovery procedures is logistics, which includes the materials being carefully prepared and sorted prior to delivery. The processing plants are potentially able to achieve a turnover of more than one ton per hour (ref. recovinyl).
