Useful information and cost implications
Consider the cost of corner keys:

Standard Corney Key
x 4/5 times the cost =
Gas Corner Key
A Gas Hole Punch Tool Kit could save you the cost of gas corner keys (see web link and photos below):
Please note: Collars and sleeves will be required for this method, but the cost of collars and sleeves is minimal in comparison to the cost of gas corner keys.
Gas Lock Seals™:
Gas Lock Seals™ are adhesive strips which can be stuck directly onto spacer tube to cover corners and joints, as well as staple holes. They provide additional protection against the escape of gas inside the guarantee period of your sealed unit. If left to leak out over time, this gas loss will cause a unit to fail. See link below.
Multigas Fillers:
