Wholesale sreen mesh suppliers/web sites?

Anyone know where on the net I can get some window screen supplies like mesh and spline? All the sites I’ve found are US based. I’m sure there has to be at least a few Canadian suppliers/distributors.

I’ve always bought my supplies from Home Depot. The price isn’t too bad for the mesh but they only carry the spline in small packages. (enough to do a window or two)

Have you checked out these guys?
