Why is SillDry better than using another method to seal in your windows and doors?

SillDry is a zero waste solution that you can typically install in under 30 seconds in any weather condition (including rain and snow) at temps 30 below zero to 130 degrees. With a built in slope, Smart Accordion Technology, and built in shims, all the work is already done for you. The main other flashing is a series of tapes that is very labor intensive, can’t be done when the weather is too cold, too hot, or even when it’s raining.

Does SillDry meet the building code requirements?

Yes - SillDry meets and exceeds the 2018 ICC and IRC building codes. Specifically SillDry meets and exceeds the 2018 IBC Code section 1404.4, 2018 IRC code section R703.4 as well as the ASTM standard set forth in ASTM E2112-07.

Can SillDry be used with replacement windows?

Yes. As long as you are replacing the window and its entire frame you can use SillDry. The only time you can’t use SillDry is when you are using a replacement window insert and using the existing frame.

Can you use SillDry with doors?

Yes. Highly recommended for use with all exterior door systems.

Why do I need to add an additional 1” to the manufacturer’s recommended rough opening height?

When should i order silldry?
