Frequently Asked Questions

Q: Are the sizes listed exact or rough opening? / How do you determine rough opening?

A: The sizes listed on our inventory page are always going to be net frame dimensions (tip to tip). It is up to your installer to determine the appropriate rough opening size. General rule of thumb is to add ½” to the net frame dimensions, but this is up to interpretation and should be decided by your installer.

Q: Do the windows come with a nail fin?

A: No – they come with a block frame.

Q: How do you tell if the window is Left Inswing or Right Inswing?

A: Everything is from the ‘inside looking out’ and our “left vs right” refers to which side the window opens from. So from inside the house, if you want the window to open on the left side and swing left to right – then it is a LEFT inswing. If you want the window to open on the right side, and swing open from right to left – then it is a RIGHT inswing.

Q: How fast do the windows ship?

A: This depends on the quantity of windows and the sizes. Smaller sizes are sometimes pre-boxed and can be ready to ship in 1-2 business days. Larger windows or bigger orders can take longer, up to 1-2 weeks. Please call for availability if you are needing windows shipped faster.

Q: What color are your ‘in-stock’ windows?

A: Our in-stock windows are all-white (inside & outside) and made of uPVC. Specialty colors are also available to order with an extended lead time.
