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 13788:2002.

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.
