1.02 Doors The majority of doors are manufactured to imperial dimensions, but the imperial sizes are usually quoted in metric units. Standard metric sizes for internal doors are 2040 mm x 526, 626, 726, 826 and 926 mm with thicknesses of 40 or 44 mm. Fire doors are rated either to BS 476-22: 1987 (e.g. FD 30) or to the European Standard BS EN 13501-2: 2003 (e.g. E30) for integrity in minutes. The ratings are normally subject to the use of appropriate frames with intumescent strips and any glazing being factory-fitted. In certain locations, the Building Regulations Part E, related to the age of sound, require minimum sound reduction criteria, and these can be achieved by the use of appropriately sealed doorsets. The standard metric size for external doors is 2000 x 807 mm (1994 mm x 806 and 906 mm to BS 4787-1: 1980) with thicknesses of 40 or 44 mm. Metric external door frames for 2000 x 807 mm external doors are typically 2100 x 900 mm coordination size (work size 2095 x 890mm) with hardwood threshold and coordinating size 2053 x 900 mm (work size 2043 x 890 mm) without threshold.

1 WINDOWS AND DOORS 1.01 Windows and door frames are generally available in four materials: 0 0 0 0

Wood Steel Aluminium alloy Unplasticised polyvinyl chloride (PVC-U)

Additionally, frameless glass doors are manufactured from 8 to 19 mm toughened glass using stainless steel fittings. The maximum door size being dependent on the weight of glass and the type of glass fixing adopted. As much work in the construction industry related to windows and doors is within the field of replacements, a significant proportion of products are based on imperial dimensions, although they may be expressed both in imperial and metric measures.

1.02 Windows The typical range of window types (BS 644: 2003) is illustrated 38.1. The modular range of windows (BS 644: 2003) is based on increments of I50 mm in height and 300 mm in width. The equal divide range also has height increments of 150mm, but the widths are related to standardization of components in the manufacturing process. The two standard ranges are listed in Table I. The following standards relate to windows constructed from the standard materials; Timber (BS 644: 2003), Aluminium alloy (BS 4873: 2004), Steel (BS 6510: 2005) and PVC-U (BS 7412: 2002). The safety aspects of cleaning windows are specified in BS 8213-1: 2004. Where required by the Building Regulations Part B 2000 (2006 Edition), fire escape windows must be provided with a clear opening of greater than 0.33 m2 and a minimum clear dimensions of 450 mm. (e.g. 450 x 735 mm). These windows must not be restricted or lockable with removable keys. Safety considerations (BS 6180: 1999) dictate that any opening window less than 800mm from the floor should be protected to 800mm by a barrier or restricted to less than l 0 m m opening. It is a requirement (BS 6262-4: 2005) that all glazing less than 800 mm above floor (or ground level) should be of safety glass. Large openings up to 1100 mm above floor level should be guarded to that level when there is a drop outside of more than 600 mm (BS 8213-1: 2004). Window Energy Ratings (WERs) are an established measure of window energy efficiency. A formula combines the elements of solar heat transmittance, U-value and air infiltration to produce an overall rating on the A-G scale, with A the most energy efficient

1.03 Access for disabled people The Building Regulations Part M - 2004 edition, requires a wheelchair access into buildings with a threshold no higher than 15 mm. Normally, the minimum effective clear entrance width required is 800mm in new buildings, but 1OOOmm in buildings used by the general public. Visibilty zones are required in doors between 500 mm and 1500 mm from floor level. Windows also need to be carefully designed so that a transom interrupting vision for a seated person should not be between 900 and 1200 mm from the floor. The height for window controls to be used by people in wheelchairs should be between 800 and 1000 mm from the floor. 2 PIPES FOR PLUMBING AND DRAINAGE 2.01 Pipes for the conveyance of liquids and gases vary widely in material, quality, size and ting methods. Many types are still based on inch measures and Whitworth screw threads, particularly as these were and are widely used not just in the United Kingdom but also in continental Europe. Even where pipe sizes are metricated, they do not always conform to the recommended series of dimensions. The standard (BS EN IS0 6708: 1996) recommends nominal sizes in millimeters (DN) for pipework systems. The DN designation may refer to either the bore or the outside diameter, which would then be referenced as DN/ ID or DN/OD respectively. The nominal sizes do not relate to exact sizes, and many other size designations are also used. The preferred DN values (BS EN I S 0 6708: 1996) are: 10, 15, 20, 25, 32, 40, 50, 60, 65, 80, 100, 125, 150, 200, 250, 300, 350, 400,450,500,600,700,800,900, 1000, 1100, 1200, 1400, 1500, 1600, 1800, 2000, 2200, 2400, 2600, 2800, 3000, 3200, 3400, 3600,3800 and 4000. The specifications for domestic water services in buildings are described in the standards BS 6700: 2006, BS EN 805: 2000 and 38-1

2.04 Insulation Pipes carrying hot or chilled liquids, or in exposed conditions, will be insulated. The thickness of insulation will typically be between 25 and 75 mm depending on material used and the size of the pipe. After allowing for any such insulation, the space allowed for any pipe should be between two and three times its actual diameter which will allow for sockets, ts, bends and clearances. The standard BS 5970: 2001 as the Code of Practice, describes the types of insulating systems appropriate for various temperature ranges and BS 5422: 2001 indicates insulation thicknesses required under various conditions.

2.09 Plastics Both the types of plastic used for pipes and their uses are numerous. Consequently, there are a considerable number of British and European Standards governing this range of materials. BS 6700: 2006 has many useful references and lists the following plastics for domestic water services - polybutylene (PB), polyethylene (PE), cross-linked polyethylene (PE-X), unplasticised polyvinyl chloride (PVC-U), acrylonitrile butadiene styrene (ABS). In addition, chlorinated poly vinyl chloride (PVC-C), polypropylene copolymer (PP)

AND DISTRIBUTION

3.01 Electricity supply and distribution cables are mainly: Armoured cable for intake (not covered here, see the technical literature) 0 PVC insulated, in conduits of steel or plastic 0 PVC insulated, PVC sheathed Mineral insulated copper (or aluminium) conductors General guidance on the use of 450/750 voltage cables is given in the standard BS 7540: 2o05.

3.02 PVC double-insulated cables These are normally used in electrical distribution for the smaller building types. Guidance on the use of PVC insulated cables is included in BS 6004: 2000. Table X gives the dimensions of PVC insulated cables, which are often accommodated in small ducts or voids in the construction. Conductor cross-sectional areas of 1 .O and 1.5 mm2 are used for lighting circuits, while ring mains require conductors of 2.5 mm2. Light and heavy duty cookers or showers require 6.0 and 10.0 mm2 conductors respectively. Since earthcontinuity conductors are now used in all circuits, all cable types have integral earth conductors. Cables with three insulated cores plus earth are used for circuits with two-way switching of lights. Flexible electrical cords for the connection of mobile and portable equipment are detailed in Table XI. Heat resisting (1 10.6 rubber cable is described in the standard BS 6007: 2006.
