NOTE FROM OUR CLIENT - JAN 2010:-
I thought you might be interested to see the attached picture of our barge crossing the North sea showing off the eight 'RED' skylights that you supplied to us in November 2007. We are very pleased with them, no leaks and excellent insulation in the recent snow proven by the fact that we have to sweep it off as it won't melt even with 20deg c inside.
Please feel free to use the picture for marine publicity in return for a link to our website. Our barge is a 1927 Dutch ex commercial luxemotor converted into a private cruising home in 1999. She is 24m x 47 more at www.mvesme.co.uk We have had many positive comments from other barge owners.
Best regards
Chris Grant
