Customer Questions & Answers

Is this product miami/dade hurricane rated?

Is this miami dade impact resistant per current building codes?
Asked by: T2
There is a Notice of Acceptance NOA no. 15-0219.01 and a Florida Approval no. 11669.1-R2 for the LightWise Vinyl Frame windows, however, they do not have a large and smaill missile impact rating and would require shutters in the event of a storm. The 24x48 (r/o 27-7/8" x 51-1/2") Decora LightWise Hurricane Resistant window has the large and small impact rating and would not require shutters. It is built into a white channel within a 2x6 wood buck. #100688

Will the 32x16.375 fit in a rough opening of 33.5x18? Also, what is needed for installation?

Asked by: D1nonlysnshn
The recommended rough opening for a 32x16" (nominal) LightWise Vinyl Frame Window is 33-3/16x17-5/8." Your opening should be adjusted to this size before installation. These windows come with a nailing fin for installation.

what is the Rough Opening for the window I ordered from you online:47.5X 32X 4.75?

the specification information below the product details calls out 41 inches for both rough opening width and rough opening height. This seems to be a mistake...
