Some of you may recall me posting re dismantling & transporting an Alton Greenhouse.
Well it's now transported and mantled in our garden.
One of the last jobs was fitting the Bayliss automatic openers to the roof vents.
They work fine - but lift the vents beyond the horizontal.
Today we had the first heavy rain since fitting the openers.
The vents were wide open and the rain falling on the glass ran to the top edge of the vent and then into the greenhouse.
Should I reglaze the vents but use mastic to proof the channels against water?
