How does a vinyl windows operation compare with others?
There are two considerations: Active operation and passive operation. Vinyl has self-lubricating properties that reduces friction and makes sliding easier. Vinyl also doesn’t warp, swell, twist or distort, so it stays easy to operate. Crack-free seams, the inert qualities and dimensional stability of vinyl, provide the advantages for its “passive” operation: glazing stays sealed, the unit is hermetic, and structural integrity is maintained.
