product performance and certifications

ODL doorglass systems protect against moisture and air infiltration in two areas:

1. Infiltration into the insulated glass air space through the glass seal.
2. Infiltration from the outside that attempts to penetrate the frame seals against the door and the glass.

ODL doorglass includes premium components that enable certification by the Insulating Glass Certification Council (IGCC) as meeting the requirements of ASTM E 2190, that evaluates performance, durability, and longevity. There are three main parts to the standard:

1. The High Humidity Test subjects samples to high humidity and temperature with the objective of forcing moisture into the sealed air space in an IG unit.
2. Accelerated Weather Cycling simulates weather cycling from hot to cold extremes with moisture added during the hot cycle.
3. The Volatile Fog Test shows that components, or trapped impurities, will not out-gas a volatile fog, which could result in a deposit on the interior glass surface. No fog must be visible at arm's length.

ODL doorglass must survive our test of 25,000 slam cycles, so you can be assured that it will remain intact when your exterior door occasionally slams shut.

Blinds + Glass are tested through 10,000 raise and lower cycles to ensure years of reliable operation.

Sound Transmission Class (STC)  is expressed in decibels (dB) and is used to measure a building material's ability to reduce sound. A higher STC rating translates into more reduction in sound. Laboratory testing is used to measure the resistance of partitions such as walls, windows, or entry doors to the passage of sound.

Typically the material with the lowest resistance to the passage of sound has the greatest impact on a partition's STC value. Poor construction practices can also nullify a partition's sound reduction properties. Cracks due to improperly fitted doors or windows can be a prime source of sound leakage.

Select ODL doorglass styles reduce sound transmission from the outside, often a desired feature in densely populated areas.

ODL conducted third party IAS-accredited lab testing on a range of doorglass configurations. All of the doorglass samples were 22" x 64" except the sliding patio door blind which was 33" x 74". These sound transmission loss tests were conducted in accordance with ASTM E 90. The Sound Transmission Class (STC) rating was calculated in accordance with ASTM E 413. Test results and benchmark values are presented below.

Opacity is an indicator of how much light passes through a material. For glass, a higher opacity will mean that less detail can be seen when you look through it, which translates to higher privacy when used in homes and buildings. 

The level of privacy that a piece of glass or specific glass design offers is important to know in order for homeowners to feel secure in their homes and know what the opacity of their purchase is. However, there is no industry standard for measuring privacy, which results in a subjective opacity scale that requires interpretation from manufacturer to manufacturer. 

Beginning in 2023, ODL, Inc. has instituted a new privacy rating system that uses a standardized, repeatable test so that you know exactly what level of privacy you are getting in each ODL product. This new system helps professionals and homeowners understand more about the glass they purchase and takes the guesswork out of opacity and privacy. 

ODL’s privacy rating system uses a process that tests the amount of light that is able to pass through the glass that we use in our stylized products. Using a tool called a spectrophotometer, every texture or pattern of a glass design is tested to see how much light passes through each particular part of the piece. The readings from the spectrophotometer are then used to calculate the exact privacy level for each glass design.

The new privacy rating system from ODL assigns each glass design and style into one of four categories: Low Privacy, Medium Privacy, High Privacy, and Maximum Privacy. This new system replaces the previous number scale and provides a precise and proven opacity level for every ODL design.

ODL products demonstrate high degrees of structural integrity when tested to industry standards for air tightness, water tightness, wind resistance, and forced entry resistance. ODL doorglass products have been tested to standards such as TAS 201, 202, and 203, ASTM E330, E1886, and E1996.

ODL doorglass in TriSYS®, Evolve®, VentLite, standard, and many other frames were tested at an independent third party test agency to the specifications listed above and were rated very highly.

ODL is certified to NAMI's Quality Assurance Program and ODL Doorglass Units are listed in NAMI's Structural Program.

NAMI's Quality Assurance Program is accredited by International Accreditation Services (IAS). Inspections are performed in accordance with ISO/IEC 17020 Guidelines. Products tested and certified to applicable standards listed within NAMI Structural Programs are eligible for this program.

Design Pressure (DP) testing measures the performance of fenestration products to withstand positive and negative pressures. To provide design pressure performance specifically attributed to doorglass, ODL doorglass frame, and IG combinations were tested in fixed door slabs to isolate and focus all the design pressure against the doorglass assembly. Doorglass design pressure performance is typically superior to door system design pressure performance.

The 2023 Florida Building Code (FBC) has wind zone specific performance requirements for design pressure. Other states continue to adopt DP requirements.

Design pressure requirements can vary based on product location on the building, height of the building, density of buildings, and wind zone designation. The positive DP number is the standard for wind blowing at the building (windward) and the negative DP number represents the vacuum pressure on the opposite side of the building (leeward).

All ODL doorglass products (decorative doorglass, clear doorglass, Blinds + Glass) with FiberMate®, FiberPro®, HP, and Impact-Rated frames are certified to meet 2023 Florida Building Code (FBC) DP requirements in 1- and 2-story buildings. 

Transoms have a +100/-110 rating for wood sills and +100/-130 rating for composite trims for a rectangular shape; for curved shapes, the rating is ±90, and for square shapes, the rating is +80/-130. Visit the Florida Building Commission Product Approval website for ODL's FBC Product Approval FL4554-R5 for further details.

ODL Impact-Rated doorglass has a Florida Building Commission (FBC) component approval, FL14935-R4, that allows it to be substituted in any glazed door or sidelight with an approved missile impact FBC approval or Miami-Dade County NOA. Typically no additional testing will be required. Both the original approval and the component approval need to be provided to the building inspector for approval. Impact-Rated doorglass cannot be used with an approved opaque door impact product to create an approved glazed door.

Visit the Florida Building Commission Product Approval website for ODL's FBC Product Approval  FL14935-R4 for specific model numbers and associated DP ratings for our impact units.

Non-impact doorglass, depending on door slab and configuration, has DP ratings from ±45 to ±80. Specific DP ratings are included in ODL's Florida Product Approvals for non-impact doorglass products, found in product installation instructions. Non-Impact products must be covered during storms in the WBD and HVHZ area.

All sizes and styles of ODL doorglass have Florida Statewide Approval through the Florida Building Commission (FBC). ODL doorglass has FBC Product Approval which allows substitution in any glazed door or sidelight.

No additional testing is typically required. Both the original approval and the component approval will need to be provided to the building inspector. For more information on FBC component approval, please visit Florida Department of Community Affairs.

ODL doorglass has the following non-impact approval per the Florida Building Commission:

• FL15260 and FL 20335 — All ODL doorglass (decorative doorglass, clear doorglass, Blinds + Glass) in various frame styles of FiberMate®, FiberPro®, or HP resins
• FL14440 — Vent door light with screen assembly
• FL4554 —Transoms

Thermal performance of door glass is measured by two properties: resistance to heat flow and resistance to sunlight warmth.

• Heat flow is expressed by the U-factor value; less heat flow yields a lower U-factor value.
• Resistance to sunlight warmth is measured by the Solar Heat Gain Coefficient (SHGC); less sunlight warmth through the window yields a lower SHGC.

ODL Exterior doors are available in 20-minute fire rated with hose stream. Please see Fire Rated Fiberglass Doors at ODL for more information.

While foam filled exterior doors are exempt from flammability requirements as, stated in IRC 303.5.5, ODL continues to offer safer products.

Detailed resin performance can be found in FL29465 and Miami-Dade NOA # 23-1013.12
