I have received another malicious e-mail, from the "administrator". The address took me to this site, I had to log in, then there was a message from the administrator saying that I has viruses on my computer and was banned. Suggested that I click onto you virus checking site. Big mistake, looks genuine, but instantly states that I have many tojan horses etc, it takes Nortons at least 4 hours to do a full system scan on this computer. Luckily Nortons blocked this site as it was one of those that does not take no for an answer. I am sorry but I cannot risk logging onto your site again.

I have had condensation problems on my boat, which I have fixed by double glazing using 4mm polycarbonate sheet. I have retained these using ball catch type fastenings, so they seal to the inside of the wood frames. Polycarbonate is 4 to 5 times less thermally conductive than glass and 1000 times less conductive than aluminium. The 50mm air gap that is left is larger than normally used for double glazing, so there will be some convection currents, but as most window frames have drain holes, hardly a problem. This method works really well with Houdini hatches. You do not need to add foam seals if there is a reasonably good contact face between the wood and polycarbonate. The panels are easilly removable by the addition of a couple of small brass handles. Polycarbonate is not cheap but it does not break like acrylic. It does cratch easily but is available hard faced, but at a price. Cost per window £20, cut to size, + 6 catches @ £0.70 each + carefull drilling and tapping etc.
