Specifying Windows and Doors There are two main types of plastics used in the manufacture of windows and doors, the dominant one being PVC-U, with Glass Reinforced Plastics (GRP) recently appearing on the scene. Like anything else, to obtain the best product suitable for a particular use it is important to get the specification right. It is important to ensure that each party to a contract knows their responsibilities and it is vital for a specifier to give the correct information to a manufacturer to enable the correct product to be manufactured. The BPF have published a useful document entitled "Guide to the specification and use of plastics windows and doorsets", reference W364/1. The following clauses would be deemed the most relevant:
By adhering to the guidance in this document, any chance of mistakes caused by confusion, or misleading information, will be minimised. It can also minimise costs by reducing over-specification, and clear specifications can ensure accurate comparisons between potential suppliers. If you would like to speak to a BPFWG member who could advise you on the specification of your windows and doors, then please click here. Hopefully the information provided above will help you to make the right decisions throughout the specification process.
