DOORS&WINDOWS NEW LICENCES FOR BUTT JOINT PATENT ISSUED TO CASEMENT MANUFACTURERS »»A LONG TIME AGO, MASTERFRAME, the sash window specialists, deduced that most homeowners who wanted really pretty looking windows did not want shiny plastic, mitre welded ones. According to Alan Burgess, Managing Director: “We knew wood foil, with traditional butt joints was the answer, however there was a challenge in that most mechanical joints are open ended, meaning water penetrates easily. What was needed was a new method of joining the sections together to provide a fully sealed waterproof joint, which had a traditional “butted” appearance. “Ray Rabett, our Technical Director, came up with a clever solution, which was patented in 2005. “This new and novel method, which was another first for Masterframe, meant we have led the sash window field with an authentic, vertical butt jointing method ever since. It now appears that casement manufacturers are finally catching up.” Masterframe has noticed that millions are being invested by fabricators buying new Graff welders, believing these are the only machines capable of providing a neat solution. However TMS, in association with Masterframe, has now found far cheaper solutions for welding butt mitred joints. Alan continues: “Many casement manufacturers are now discovering that sales of their new flush casement depends upon them obtaining permission and a license for our patent.” First to get this approval is fellow VEKA fabricator and long-time customer of Masterframe, Michael Hagan of Aztec Windows (Coventry) Ltd. Michael said: “Having looked at other construction methods, it was clear that the Masterframe method was really neatly finished, sturdy and more reliable than any of the other methods considered. Initially, like so many other fabricators, we were blissfully unaware that a patent existed, but now we have the agreement, we can use it to prove our customers won’t get sued!” As welded butt joints becomes more popular, Masterframe are in negotiations with a number of interested parties and Alan concludes: “On the whole we have little objection to issuing licenses to fellow fabricators, just so long as they aren’t making sash windows!” If you are thinking about making windows using this jointing method, welded or mechanical, you will require permission and a license.
