What each certification actually means

A logo grid tells you nothing. This page says what each body verifies, what it means for the person specifying the window, and exactly what evidence we can produce — including where we have none.

MIAMI-DADE COUNTY NOA CERTIFIED

Six active Notices of Acceptance

Every one rated Large and Small Missile Impact — casement, fixed, awning, sliding glass door and storefront systems, at design pressures from +60/−60 up to +115/−115 PSF.

Miami-Dade County is the hardest fenestration approval in the United States: full-scale large-missile impact, 9,000 cycles of pressure loading, and a Florida-licensed engineer of record on every drawing. There is no partial credit — a product either holds a NOA or it does not.

A NOA is issued per series and per configuration, so the number covering your exact unit is issued in writing with your quotation.

A rejected submittal costs you the schedule, not just the paperwork — that is why we confirm the exact NOA in writing before you specify it, not after.

SECTION 1

US Mandatory Coastal & National Compliance

Energy performance

The only figures on this site a stranger can check without asking us for anything.

NFRCNational Fenestration Rating Council

What it verifies: Whole-product energy performance — U-Factor, Solar Heat Gain Coefficient, Visible Transmittance and Condensation Resistance — measured by an accredited laboratory under a standard procedure, then listed publicly.
What it means for you: A whole-product NFRC rating cannot be argued with at plan check, and it is not the same as a centre-of-glass figure. Centre-of-glass quietly omits the frame, which is where an aluminum window either performs or does not.
What we can show you: Our production is a registered, searchable NFRC Product Manufacturer — confirmed directly in the NFRC directory’s own manufacturer search, with 44 certified product lines listed across casement, awning, picture, single and double hung, sliding windows, specialty windows, glazed wall systems, sliding glass doors and swinging exterior doors. A CPD number is issued per model and per glazing build-up, so ask us for the one covering the specific model you are specifying and we will confirm it in writing before it goes into a submittal — the same discipline we apply to every other figure on this site.

California Title 24California Title 24California Code of Regulations, Title 24 Part 6 — Building Energy Efficiency Standards

What it verifies: Title 24 Part 6 is a compliance calculation run on a building in a climate zone, not a certificate a window can hold. What a window contributes to it is an NFRC-certified U-factor and SHGC.
What it means for you: This is why nobody can sell you a “Title 24 certified” window, ourselves included. Compliance belongs to the building, and the same window can pass in one climate zone and fail in another. Anyone offering the certificate itself is describing something that does not exist.
What we can show you: 35 of 71 certified double- and triple-glazed configurations clear U-0.30 / SHGC-0.23. Which one suits your opening depends on the climate zone and the calculation, and we confirm it in writing. NFRC-certified U-factor and SHGC. Ask for the configuration that meets Title 24 in your climate zone and we will confirm it in writing with the quotation.

ENERGY STARUS EPA energy efficiency programme

What it verifies: That a specific model meets the EPA threshold for a specific climate zone. It is awarded model by model and zone by zone, never to a company or a product range as a whole.
What it means for you: Any supplier who tells you their whole range "is ENERGY STAR" is telling you something that cannot be true. Ask which models, in which zone, and ask for it in writing.
What we can show you: Qualified models are available. Tell us your climate zone and we will confirm in writing which ones qualify there. We do not print a blanket claim, because a blanket claim would be false.

Performance and safety

Structural, air, water and glazing standards, tested and certified on our own production.

AAMA / FGIAFenestration and Glazing Industry Alliance, formerly AAMA

What it verifies: Finish durability and forced-entry resistance, among other things. Powder-coat finishes are specified to the AAMA finish standards, and forced-entry resistance is tested to AAMA 1304.
What it means for you: The AAMA finish grades are the reason a powder coat carries a twenty-year warranty rather than a hopeful sentence about quality.
What we can show you: Our systems are specified against these standards, with confirmed AAMA/FGIA (US-standard) certification across both the aluminum and UPVC window lines. Test reports available on request.

WDMAWindow & Door Manufacturers Association

What it verifies: That a product’s stated performance ratings were tested by an independent third-party laboratory rather than self-declared.
What it means for you: The distinction between a tested number and a claimed number is the whole game when you are specifying a window you cannot put in a test chamber yourself.
What we can show you: Performance figures on this site are laboratory figures from our own testing. Where they are NFRC-certified we publish the directory number so you need not take our word for it.

NAMINational Accreditation & Management Institute

What it verifies: Third-party certification and in-plant inspection for fenestration performance.
What it means for you: In-plant inspection means someone external checks that what leaves the line matches what was tested. Certification without ongoing inspection only describes one sample on one day.
What we can show you: We hold an active in-plant NAMI certification, renewed annually and current through December 31, 2026. Our window products additionally carry NFRC and NAMI certification; certificate IDs are available on request.

IGCCInsulating Glass Certification Council

What it verifies: Durability of the insulating glass seal, by accelerated weather cycling.
What it means for you: Seal failure is the commonest way an insulated unit dies — fogging between the panes, ten years in. It is also what the twenty-year glass warranty covers.
What we can show you: Standard insulating glass supplied to the North American market by our production lines is IGCC certified.

SGCCSafety Glazing Certification Council

What it verifies: That safety glazing meets the impact and breakage-pattern requirements of the US safety standard.
What it means for you: Safety glazing is mandatory in specific locations — doors, sidelights, low sills, wet areas. An uncertified pane in one of those openings fails inspection.
What we can show you: Standard glazing supplied to the North American market by our production lines is SGCC certified. Tempered safety glass is standard across the range.

Regional approval

This is the group most often overstated in our industry, so read the wording closely — it is precise on purpose.

Miami-Dade CountyMiami-Dade CountyMiami-Dade County Product Control

What it verifies: Impact resistance, water tightness and air infiltration under the toughest hurricane protocols in the United States.
What it means for you: A Notice of Acceptance is a specific numbered approval issued by the county. Being tested to the same standards is a real and substantial thing — but it is not the same thing, and only one of them has a number you can put in a submittal.
What we can show you: Our impact systems carry six real, current Miami-Dade County Notices of Acceptance, every one rated Large and Small Missile Impact — casement, fixed, awning, sliding glass door and storefront, at design pressures from +60/−60 up to +115/−115 PSF. We also hold Florida DBPR statewide Product Approvals, a different instrument covering a wider product range — see the DBPR entry below. A NOA is issued per series and per configuration, never to a company as a whole, so the number that matters is the one covering the unit you are actually ordering: send us the product and the project address and we issue that number in writing with your quotation.

Florida DBPRFlorida Department of Business & Professional Regulation

What it verifies: Statewide Florida Product Approval, administered by the DBPR and separate from the Miami-Dade county system.
What it means for you: Florida has two parallel routes. A product can satisfy one and not the other, and which you need depends on where the building is.
What we can show you: We hold real, checkable DBPR Florida Product Approvals — 21 in total, across exterior doors (swinging and sliding), panel walls (curtain wall and storefront) and windows (awning, horizontal slider, fixed, casement and single hung). Most are Approved; five are currently Applied For and not yet valid for use, and we say so rather than counting them as ours. Two of our window approvals carry full published engineering detail: single hung at +75.0/−75.0 PSF and fixed at +60.0/−60.0 PSF, both Large Missile Impact and HVHZ-approved, evaluated by a Florida-licensed professional engineer under the 2023 Florida Building Code, 8th edition. A Florida Product Approval is issued per product and per configuration, so ask us for the number covering the unit you are specifying and we issue it in writing with the quotation.

READING THE LABEL

What each NFRC number actually means

Every NFRC-certified product carries a label with these figures. Here is what each one measures and the published scale it sits on — the same scale for any manufacturer’s label, not a NEXWD-specific claim. Ask us for the CPD number covering your exact configuration and look up the real figures yourself.

U-Factor

How well the whole unit — frame and glass together — keeps heat from escaping. Measured for the complete product, not just the center of the glass.

Published scale

0.20 – 1.20

Lower is better

Solar Heat Gain Coefficient (SHGC)

How much solar heat passes through. A lower number blocks more heat, which matters more in hot climates; a higher number lets more warmth in, which can help in cold ones.

Published scale

0 – 1

Depends on your climate zone

Visible Transmittance (VT)

How much visible daylight passes through the glass. Higher means a brighter room without turning on a light.

Published scale

0 – 1

Higher lets in more daylight

Condensation Resistance (CR)

How well the unit resists moisture forming on the interior glass in cold weather. Optional on an NFRC label — not every certified product lists it.

Published scale

1 – 100

Higher resists condensation better

Air Leakage (AL)

How much outside air leaks through the assembly itself — the frame and sash joints — not the wall around it.

Published scale

≤ 0.3 cfm/ft²

Lower is better

SECTION 2

Global Quality & Manufacturing Certifications

Codes and international standards

The documents your specifier already works in, and the markets these systems were built for.

CSIConstruction Specifications Institute

What it verifies: Nothing about the product — CSI is the organising system for specification documents, MasterFormat.
What it means for you: Documentation arriving in the section numbers your specifier already uses saves an afternoon per package. Small thing, noticed every time.
What we can show you: Product documentation from our production lines is organised to CSI MasterFormat sections.

CSACanadian Standards Association

What it verifies: Fenestration performance under the joint North American standard, AAMA/WDMA/CSA 101/I.S.2/A440.
What it means for you: It is one document covering the US and Canada, so a rating under it travels across the border with the project.
What we can show you: Both our and our products are rated to the joint standard.

CEEuropean conformity marking

What it verifies: Conformity with EU requirements for placing the product on the European market.
What it means for you: The platforms originate in European systems. Useful context, but a CE mark is not a US rating and we never present European test data as one.
What we can show you: Our production lines carry CE marking for the European market. Where a figure on this site is converted from European test data, the page says so on the figure itself.

AS 2047AS 2047Australian Standard for windows and doors

What it verifies: Wind and water performance for the Australian market.
What it means for you: Relevant mainly as evidence that these systems are built to several national standards rather than one, which is a reasonable proxy for how each factory works.
What we can show you: Our production lines also build to AS 2047 for the Australian market — a real part of the business: about 20% of our current sales go to Oceania, alongside roughly 70% to North America and 10% to Central America/the Caribbean.

Quality system and independent inspection

Company-level credentials, not product ratings. They say how each factory is run and who is allowed to check it — which matters on a container you have not seen, but is a different claim from anything above.

ISO 9001:2015ISO 9001:2015Quality management system

What it verifies: That a factory operates a documented, audited quality management system — how work is controlled, how defects are handled, how records are kept. Worth knowing: ISO itself certifies nobody. It writes the standard; an external certification body audits against it and issues the certificate, so "certified by ISO" is never a correct phrase, from anyone.
What it means for you: It says nothing whatsoever about a U-factor. It says a factory has a process and someone audits it, which is about consistency between units rather than the performance of any one of them.
What we can show you: Held on our own production lines. We are obtaining the issuing certification body and certificate number so we can supply them on request — a standard on its own is not verifiable, whereas a certificate number in the issuer’s public directory is.

SGSIndependent inspection and testing

What it verifies: Whatever you commission it to verify — production conformity, quantity, packing, loading.
What it means for you: This is the practical answer to "how do I trust a container I have not seen". You can commission a pre-shipment inspection on your own order, paid by you, reporting to you.
What we can show you: Available on request for your order. Ask us and we will arrange access.

Bureau VeritasIndependent inspection and certification

What it verifies: The same function as SGS — an outside party verifying what actually leaves either factory.
What it means for you: Two options rather than one, which matters if your own QA programme already has a preferred inspector.
What we can show you: Available on request for your order.

CMA / CNASCMA / CNASChina Metrology Accreditation / China National Accreditation Service for Conformity Assessment

What it verifies: That a testing or calibration laboratory in China is itself accredited to run the tests it reports — a lab-accreditation mark, not a product certification like NFRC.
What it means for you: When a Chinese factory’s in-house or local test report carries a CMA/CNAS mark, it means an independent body has checked that the lab issuing the report is competent to do so — useful supporting evidence for domestic testing, but it does not substitute for a US body’s own certification.
What we can show you: Requested from our production lines; not yet confirmed which specific test reports carry a CMA/CNAS-accredited lab’s mark. Written here as pending rather than assumed.

QualicoatQualicoatInternational quality label for architectural aluminum powder coating

What it verifies: That a powder-coating line meets defined film thickness, adhesion and accelerated-weathering requirements for architectural aluminum finishes — a coating-process license, held by the applicator, not by NEXWD.
What it means for you: Sits in the same territory as the AAMA finish standards above — a licensed Qualicoat line is one more way a powder coat backs up a multi-year finish warranty with an actual audited process rather than a promise.
What we can show you: Requested for our own coating line; not yet confirmed as a licensed line. Written here as pending rather than assumed.

FAQ

What does NFRC certified mean for a window?

It means the whole product — frame and glass together — was measured by an accredited laboratory under a standard procedure, and the result is listed publicly in the NFRC Certified Products Directory under a CPD number. It is not the same as a centre-of-glass figure, which omits the frame. Ask us for the CPD number covering the system you are specifying and you can look it up at nfrc.org yourself.

Are your windows approved for Florida projects?

Yes. We hold six current Miami-Dade County Notices of Acceptance, every one rated Large and Small Missile Impact, covering casement, fixed, awning, sliding glass door and storefront systems at design pressures from +60/−60 up to +115/−115 PSF. We also hold Florida DBPR statewide Product Approvals covering a wider range under the 2023 Florida Building Code. Because a NOA is issued per series and configuration, send us the project address and the exact product and we will issue the number that covers it in writing.

Can I get the actual certificates?

Yes. Certificate and approval numbers, and test reports, are available on request. Where a rating sits in the NFRC Certified Products Directory we publish its number on the product page, so that part you do not have to ask for at all.
