| has anyone ever used a system the same as aluminium windows? i used 4mm on my enclosures, glass dimensions were 465 x 535 (2 doors per 900 x 600 x 600 enclosure)
do you think 4mm is thick enough for this size? it seems fine but would crack without much force.
is this aluminium tracking you speak the same as pvc tracking just different material? |
