Built to withstand extreme weather and deliver unmatched protection and peace of mind.
Engineered for superior thermal performance, lower energy costs, and a more comfortable space.
A complete system includes the frame (structural capacity and wind-load resistance), hardware (locking points, tracks, hinges — operation and security), glass (insulation, acoustics, daylighting, safety), the sealing system (water and air infiltration performance and installation technical support from drawings can help you to install product easily.
These five elements are tested and certified together as a whole — swapping one component in isolation may invalidate the system's certified performance data.
Selecting a wind-load rating depends on the project's wind zone classification, building height, opening size, and required design pressure. Start by confirming whether the project falls within an HVHZ or other mandatory-certification zone, obtain the required design pressure (DP) value from local code, then verify that the product's NOA / CSA Florida Approval test range actually covers that pressure range. For large or custom-shaped openings, our technical team can confirm structural feasibility alongside your design intent.
Full test reports and drawings are available to support your permitting process.
Traceable Data (performance figures come from official test reports, available for the customer to review directly);
Dual-Protection System (energy efficiency and hurricane wind-load performance covered under one product line, suited to both cold-climate and coastal high-risk projects); and
Complete System Delivery (design support through installation documentation, delivered as a certified system rather than separate parts, reducing risk at inspection and approval).
If the issue is due to a defect in the product itself — not caused by installation or intentional damage — here's how it's handled: for a genuine product defect, YY WINDOWS covers both the part cost and shipping; damage caused during installation is not covered under warranty and is the responsibility of the customer or installer; intentional damage is also not covered.
Recommended process: submit a service request with details of the issue, the part(s) needed, and site documentation (photos recommended); our technical team verifies whether the issue stems from a product defect or from installation/external factors; once confirmed as a product defect, the part is provided free of charge with shipping covered by YY WINDOWS
Yes. Products go through a factory testing step before shipment to confirm there are no quality issues prior to packaging and dispatch. Inspection photos and videos are provided after testing for your review, and on-site visits can also be arranged if you'd like to see the product in person.
You don't need to memorize industry terms. Focus on two things: whether the product's certification actually covers your specific region (requirements vary by zone), and whether it was tested for Large Missile Impact — the key test for debris impact resistance. Our team will help confirm the right product line for your home's exact location and structural conditions, so you're not relying on a product that "sounds" hurricane-rated but isn't actually certified for your area.
