We are using Eagle HarborMaster Windows – special thanks to Chris Burgess of Eagle Windows for helping us with our order!  The construction and glazing of these windows is designed to stand up to a hurricane.   Testing  includes firing a 2×4 into the glass (the wood is shot out of a canon at 50 feet per second) and repeated pressure changes (up to 9,000 cycles) to simulate hurricane conditions. Needless to say – we want to put them in right.

First we use a laser level to establish a line that runs all around the building.   Next, we build out around the windows with 1/2 plywood to allow the siding to properly align with the trim.   Then two beads of silicone caulk are applied to the plywood and the window is set and fastened through the nailing flanges.

After the window is nailed to the wall the entire nailing flange and backer board is covered with Vycor – a thick piece of rubber backed with adhesive.  While the window is being installed from the outside Breck Tully makes sure that everything is square and true on the inside.

Finally the window is fastened to the  framing with metal straps that are visible in the inside photograph.  The straps are to prevent the windows from blowing out of the building due to the severe low pressure that accompanies a hurricane.
