3 Panel Dimensions - IP Note: Two sets of construction details have been produced to give the building designer flexibility within the Part L2 calculation for the total building heat loss Alpha (a). The decision on the choice of STANDARD or ENHANCED details is taken by the building designer and is determined from the Part L2 total heat loss (See Section 2). A mixture of both standard and enhanced details may be required for some projects cover width External weather sheet Internal weather sheet Overall width a 35 Insulation core Available Panel Thicknesses Insulation Overall Panel Overall Panel Core Thickness Width Note: Above dimensions are nominal, actual dimensions will vary due to manufacturing tolerances. Dimensions must always be measured from actual samples. All dimensions in millimetres. 3:2

4 [ Revised - October 2005 ] Product Data Sheet - IP1000 Applications The Ward Roof - Trapezoidal Panel IP1000 is a through fixed roof panel, which can be used for all building applications where the finished roof pitch is 4 or more. Finished roof pitch describes the actual pitch of the roof after allowing for the deflection of the supporting steel and erection tolerances. All IP1000 panels are supplied with a Polyisocyanurate (PIR) insulation system with zero Ozone Depletion Potential (Zero ODP). This panel forms the basis for a variety of construction specific applications. These are summarised as follows: Standard Industrial - LPC approved - HCFC Free Insurer approval by compliance with Loss Prevention Council Accreditation is in most respects the standard requirement for all new constructions. The standard panel with insulation and the standard construction details shown in this section ensures compliance with these requirements. All IP1000 panels comply with current legislation are CFC free, HCFC free and have zero Ozone Depletion Potential. Internal environment is an important factor in determining the way in which the building envelope is constructed. The details noted in this section using the standard panel are suitable for building with internal humidity class 1 to 4 as described in BS EN ISO 13788:2001 In terms of Part L & J requirements of the building regulations the standard construction details shown in this section are designed to be Robust and help the building designer in ensuring compliance with the requirements. Model and NBS type specifications are available for all construction applications. High humidity. Low temperature, Food Safe environments Where internal environments are considered aggressive or extreme in terms of humidity and durability, enhanced panel specifications and construction details may be required. Protective coatings to the internal liner are available that are more suitable for aggressive conditions or longer durability. In addition construction details at the panel joints, ends and junctions will require consideration along with the choice of fastener material. Ward Technical Service can provide Model and NBS specifications for specific construction applications.

8 Fastener Locations - Standard Application - IP1000 Section 3 - Ward Roof - IP Trapezoidal Valley Positions Standard End Lap Panels are fixed using self drilling self tapping high thread screws. Panels are generally fixed in the valley of the profile unless special conditions exist to make crown fixing essential. Contact Ward technical service for crown fix positions. Typically, fixing is into cold formed purlin sections of less than 3.5mm thicknesses. However screws indicated in this handbook also cover fixing to hot rolled sections and timber. See page 3:48 and Section main valley fixings are shown as a minimum, more may be required to suit project specific wind uplift conditions. Refer to section 13 for fastener references 3:7

The roof and wall panels are each fitted onto a seal which is site applied to the eaves beam. An additional site applied expanding weather seal is a applied at the roof to wall junction. The cladding supported Ward Streamline Gutter is fixed to the under side of the outer profile in the cut back region. During fixing, fillers FIPN05MP maybe trapped between the gutter and profile to prevent water being blown back behind the gutter. Fillers can also be applied full depth at panel ends as an alternative eg. FIPN85MP for 80mm thick panel. The front edge of the gutter is supported by gutter support arms fixed to the profile at centres of one metre. For best results the support arms should not be fixed at side laps. 3:11

Each type of hip is unique and must be given separate attention on detail. Supporting steel is required at each side of the hip or valley line to provide support to the Ward panels. The steelwork must be level with the purlin in all cases. On valleys a shallow gutter section must be accommodated by the steelwork detail. This may require the notching or setting back of the purlin to create sufficient clearance at this junction. Ridge Type Hip The insulated panel is fixed to the support steel and air sealed to the internal ridge trim. Rake cut fillers, manufactured to suit the angle of the hip, fill the panel profile and seal the hip flashing. Valley Type Hip The insulated panels are rake cut on site to suit the angle of the valley. The insulation is cut back on the underside on site to provide a drip edge into the gutter. Alternatively the panels may be but ended and treated with edge protection Paint. The inner skin of the panel is air sealed to the gutter which is supported on the steelwork. The panels are fastened through the gutter into the valley steelwork.

36 Roof Aperture Unit - IP1000 (Insulated Unit fitted anywhere on Slope) Single Width Unit * * * * Double Width Unit * Unit sizes to suit customer s requirements * Triple Width Unit * * * 3000 * Providing a more flexible solution to the demands of modern building, Ward Roof Apertures are made to suit the customer s specific requirements with respect to the clear opening size and the support purlin centres. Available in one panel (1.0m), two panel (2.0m) or three panel (3.0m) widths, these pre-engineered units are manufactured to suit the purlin centres of the project and virtually any downslope opening dimension. Ward roof apertures consist of a mill finish aluminium outer sheet and a pre-coated steel liner insulation core. The outer sheet can be painted to match the roof after manufacture. The aperture units are produced in the same controlled way as the insulated panels, ensuring compatibility and ease of fitting on site. The new Ward Aperture Units offer the following features: 1.0m, 2.0m and 3.0m wide units. Overall length to suit specified purlin centres on project. Opening length of any size within the unit length. Opening width options within each unit. Minimised cold bridge effect. Detailing Ward insulated panel aperture units are detailed to fit and lap at the purlin centres in a similar way to the normal panel lap joints. Within the downslope length of the unit, any specified opening can be accommodated, providing the minimum upslope and downslope dimensions are allowed. A typical example for purlin centres at 2 metre would be as follows: Max opening length = (minimum upslope end) 150 (minimum downslope) = 1500mm. Therefore any opening length up to 1500mm may be specified. Within the width of the single, double or triple units, clear openings may be ordered. The following information is required to specify the unit: Type of unit = single, double or triple width Purlin centres to customer s specification Opening length to customer s specification Opening width see technical specification Panel thickness 40, 50, 60, 80 or 100mm Section 3 - Ward Roof - IP Trapezoidal 3:35
