We recommend you buy on performance specifications rather than price. The sweetness of a cheap price is soon forgotten should a component product fail prematurely. Who will pay for the replacement part? Who will fit it? Can you get an exact replacement part?

We encourage you to think carefully about these issues when choosing hardware and componentry products for your new windows and doors.

WANZ has benchmark voluntary standards to define hardware and component products. WANZ members claiming compliance with a voluntary standard may display a WANZ Component Supplier Mark on the goods and/or the related packaging and literature.

Simply specifying that all componentry supplied for your order must meet or exceed the relevant WANZ Component Standard is a simple and effective way to ensure that you will be happy with the products you buy from WANZ member suppliers.
