New Window Update
When I returned to Skye Five a few weeks after installing the new windows, I was less than thrilled at what I saw. The small front windows seemed fine but the much longer salon windows were showing signs that the acrylic was lifting away from the adhesive tape and the the Sikaflex was separating from the forward and aft edges. This was most apparent on the side that received the majority of the hot summer sunshine. It seems that this window may be just too long for this mounting method, as thermal expansion over the four foot length was too much for the adhesive and caulking to tolerate.
During my winterisation visit in October I recaulked the forward and aft edges of this window and hope that it will remain watertight until I can reassess the situation in the spring. I already have a relatively simple fix in mind, and will keep you informed.
