Bought a great polycarbonate one end of 2014 for £40 or so...they do wobble a bit in the wind though....hence can be noisy...fixed ours with metal bands to reduce movement..its been a great little greenhouse.

I didn't get any glass at all as i have kids and wanted the best of both worlds - A greenhouse but a safe one so i didn't plan on using glass. I don't intend to take the sheets out in winter but if a Major storm was predicted over the winter with polycarbonate it gives me the option to take the panels out if needed and i could just wrap them up and put somewhere safe until safe to put them back in. I know this it a bit OTT but i could see this blowing over in very strong winds, but then so do fence panels so damage could always be a option. ( all depends where you put your greenhouse)

I think i am going to screw the frame to the 6" base ( you could always get a glue for this from most DIY shops if your not very diy competent ) Then i can but a few bricks in the inside of the 6" base to weigh it down. You could also get a few bags of sand on each corner and tie it down for the winter.

You don't need to measure all the sheets , I brought 20 sheets of 2' X 4' 4mm thick. I used 17 1/2 sheets.
For the sides i used 9 full sheets ( No cutting required ).
For the roof i used 4 full sheets - i had to cut about a 1/4" off all 4 , this might depend on how accurate your sheets where cut , might be dead on 2' might be just under / just over - mine where dead on so 1/4" off ( remember measure twice - cut once )

For the upper windows i just placed a sheet up to the frame and marked the angles , remember the clips that hook over your bottom panel, this upper window needs to sit on this clip so you get a overlap for the rain to dribble onto the lower panel. - If you are not sure you could always make a cardboard template.
If pictures speak louder than than words i can take the panels out and take some pics to show you.
Appoliges for the long post , hope it helps , If in doubt Ask - Advice is Free !

Found this in the box for my frame, hopefully it'll help you peeps with the size of the glass and what packs are needed with each size frame :smiley:

can you buy the louvre vents section on the cheap too?

Great bit of info you provide here, wish I could make use of it myself, but alas....
Heat added though because I'm sure that many will be able to grab a nice little deal will this info :smiley:

Has anyone seen these reductions in any other store? Not questioning the OP, but wondering if it has been rolled out to all stores yet.

Amazing price. A must buy.

My local has the frames and base but no glass. Salesman said the glass could be bought online but can't find any on b and q site

Which Plymouth store? Plympton or derriford? Thanks op

They are in the Meir (Stoke on Trent) store

they had got the frames and bases in Crewe. No glass packs that I could see though.
