I've tried searching the internet for replacement plastic strips that hold the polycarbonate sheets (windows) in my greenhouse, but I'm struggling.

Please see photo for a cross section of what I'm looking for...

Any help finding where I can buy these, preferably online is much appreciated!

Kindest Regards,


I'm still struggling to find what I need.  Any further ideas anyone?



Have you tried the place where you brought it from.  I brought a 10 x8 greenhouse from BQ and required a replacement part as it had become damaged . They supplied it within 7 days 



Hi Phibir.

I looked for this after your first post and tried all cross section /profile cuts and S section but i'm stuck as well,sorry.

This is going to sound stupid. Do you have a name?


When i said do you have a name. I meant a product name. Lol.

I only looked up plastic and pvc not aluminium.

Has anybody had any luck? I'm looking for exactly the same strips for a Palram greenhouse.  Have contacted Palram via their website, will let you know if I get a reply 

It's taken a month but palram have sent me the parts for a reasonable price.  Either contact them via their website or email this lady (she responded after my website contact)

The code number for the strips is P311
