Is it wise to use membranes with seamed joints? A. In our opinion joints are mechanically weak areas. Continuous “draw down” under vacuum conditions will search out any weaknesses in the seam and lead to early membrane failure. In addition seams can sometimes leave unwanted impression marks on modules - - NOT WHAT YOU WANT For J-Flex 1 piece sizing is not a problem. For you today we can offer VAC-SIL® Membranes up to 3850mm wide in 1 piece - REPEAT 1 PIECE. Q. Does colour or surface finish have any impact on membrane performance? A. Based on feedback from customers worldwide, we can see no advantage or disadvantage of different colours, or indeed surface finish. For this reason we offer:- VAC-SIL PRO® in Light Blue VAC-SIL LAMI-FLEX® in Blue / Black VAC-SIL® LAMIN8 environmentally inspired in Green / Black -: WHY? Most of our competitors offer a standard Grey or Translucent and this makes it very difficult to differentiate between suppliers. J-Flex offer these distinctive colours to distinguish materials. For better or worse J-Flex don’t hide away from our responsibilities. It is vital that VAC-SIL® LAMIN8 or VAC-SIL LAMI-FLEX® Membranes are loaded with the black coloured Peroxide / E.V.A. resistant face down against the module surface. We find the question of surface finish interesting - but in conclusion we see no evidence that one option is better than another. Commonsense says that a fabric impression will provide a natural venting path to aid release especially in hot / sticky conditions. Most of our customers do prefer fabric impression 1 side and smooth 1 side. The physical properties of the material will be exactly the same irrespective of colour or surface finish - these do not change.
