Some projects can use non-impact windows, but a general answer for all of Slidell would be misleading. The decision depends on the actual project requirements and the complete opening-protection approach. A high DP rating alone does not settle it.
Before comparing prices, establish who will confirm the applicable requirements. That prevents the quote process from being built around an assumption that later changes.
Gather the information needed for a useful answer
Start with the exact address and a clear description of the work. Replacing one existing unit and supplying a new house are different scopes. If plans or permit documents exist, include the relevant current pages.
For an occupied home, note any existing protective coverings. Do not assume that an old covering remains suitable for a different replacement opening or attachment condition.
Questions for the permitting authority and project team
- Which requirements apply to this scope and address?
- Is debris protection required for these openings?
- Is a separate protective system an accepted approach?
- What product and installation documents are needed?
- Does the proposed change affect any existing acceptance?
Keep the answers with the quote and order information.
Compare the complete options
If a non-impact assembly is acceptable without separate protection, compare suitable configurations normally. If an approved covering is part of the approach, include that system and its attachment requirements. If impact-rated assemblies are required or preferred, compare their actual documentation and scope. [5]
Do not remove a protection item from one quote just to make the totals look comparable. The two proposals need to satisfy the same project brief.
Consider the practical side of a covering system
Discuss who would deploy the system and how the openings can be reached. Consider storage, access and the owner's likely availability before a storm. Review maintenance and operation instructions for the selected system.
A lower initial product price may not be the only priority. An owner who travels frequently may weigh preparation responsibilities differently from an owner who wants a particular accepted covering solution.
Establish pressure suitability separately
The window still needs the appropriate documented pressure performance for the opening. A covering should not be assumed to correct an inadequately specified window. Review the actual assembly and installation conditions. [4]

Does choosing non-impact mean accepting a lower-quality window?
Not automatically. Impact qualification is one aspect of the selection. A suitable non-impact product can still offer premium finishes and energy options. It must satisfy the complete requirements of the project before those preferences drive the purchase.
