Waterloo Air Products has published the latest edition of The Green Book.
The Green Book provides information on Waterloo's range of grilles, louvres and diffusers in an A5 manual.

'The efficiency of air distribution systems can be significantly improved through the correct specification and selection. The Green Book is a useful tool and by using the comparative selection data, system designers can determine the most suitable air terminal device for specific applications,' said Rick Edmondson, chairman of Waterloo Air Products.

The Green Book is available direct from Waterloo by emailing mail@waterloo.co.uk or a PDF version can be downloaded from the company's website www.waterloo.co.uk
