Adding Plywood Boards to Observatory Shed
Once I had cut up the polystyrene sheets for insulation and slotted them into the recesses of the shed walls, I had ordered 7 sheets of 8ftx4ft – 6mm plywood to go over the top, these were also to be painted black.
Before I could install the plywood, I had discovered that the shed recesses were 40mm deep, but the polystyrene sheets are 50mm deep, so now the polystyrene is sticking out 10mm, so I could either cut down the polystyrene or pack out the frame by 10mm to bring it up level.
I decided to pack out the frame with pieces of plywood I cut up as well as free wood I managed to get from Travis Perkins.
Now I was ready to cut up the plywood and I panelled out the whole inside of the shed, including the inside of the door.
I also made some shutters for the window using some left over plywood and I then used more plywood to encase the surround of the base, where the pier will be going.
For my 8x6ft Pent Shed I could have done with 8 plywood sheets, but I did manage to complete the job with 7 sheets, but had to have one side of the shed wall made up of several cut pieces instead of using just one board.
Next comes painting the inside of the shed.
