Letterboxes
One letterplate - Fully tested for use in either 30 minute or 60 minute applications!*
Norseal letterplates offer you more than ever before. For the first time Norseal can offer a truly versatile letterplate giving all of the usual letterplate features together with both fire test ratings in one!
The Norseal range has been cleverly designed to achieve the normal 30 minute* standard and the less common 60 minute by using the very best of Intumescents together with both a PVC frame or more robust Aluminium frame.
Backed-up by Independent Test Evidence BS476 Pt 20:22
The range was simply superb on test, the Advantage going to 1 hour and 14 minutes and the Advantage Plus reaching 1 hour and 20 minutes in a 44mm ‘30 MINUTE’ door!(For guidance only. Please refer to our technical department for further information.)
The test was carried out in one of the UK’s leading fire test stations who were highly impressed with the design of this major new product for Norseal.
