What to Know About IWC
- Lifetime warranty: IWC offers a limited lifetime warranty, but it does not transfer to the next homeowner. Learn more about their lifetime warranty here: https://www.intlwindow.com/international-windows-warranty/
- Dual glazing, low-e glass: All products come standard with low-e glass and dual glazing, providing added thermal and sound insulation.
- Wide range of glass options: Glass options include: extreme low-e glass, laminated glass, tempered glass, argon gas, energy shield extreme glass, and ile glass (a hard-coat low-e on the 4th surface).
- Innovative weep hole system: A weep hole is a small hole at the bottom of the window that drains water that enters the space between the window sash and frame to the outside
- Sleek, low-profile latches with a modern look: IWC window latches are designed to be streamlined. To unlock a window, the latch is tilted to the side and is hard to view from the outside, offering a contemporary, more secure look.
