## Laminate Interlayer Data 

## Laminate Construction Rules

- Laminates *cannot* have embedded coatings, where embedded coatings are defined as a coating on a substrate that touches an interlayer
- Only NFRC glass layers with the NFRC approval indicator “#” can be used in these constructed laminates
- The glass layers can be tinted or coated as long as the coatings do not face the interlayer
- The interlayers in Optics5 do not have a “#” on them and therefore, only interlayers from the LBNL/NFRC “Approved Interlayer” list can be used

## Laminate Verification

- Laminates constructed in Optics5 will not have a #.
- Future versions of the WINDOW software could determine if the laminate was constructed from NFRC approved # layers
- The simulator specifies layers of the laminate, which shall all meet the # criteria
- The simulator shall provide base properties for the complete laminate assembly, including Tsol, Tvis, Rsol 1 & 2, Rvis 1 & 2, Emissivity
- IA can recreate the laminate from the specified layers and verify the calculated values

## Laminate Examples

**Laminate with one 30 mil interlayer and 3 mm glass (Clear)**Clear 3 mm + 30 mil clear interlayer + Clear 3 mm
**Hurricane laminate – three 30 mil interlayers (Clear)**Clear 3 mm + 3 layers of 30 mil clear interlayer + Clear 3 mm
**Color Layering laminate**Low-E 3 mm + 1 layer of 15 mil red interlayer + 1 layer of 15 mil blue interlayer + Clear 3 mm

## Applied Film Data 

## Applied Film Rules

- The applied films *cannot* have embedded coatings, where embedded coatings are defined as a coating on a film that touches the substrate
- Only NFRC glass layers with the NFRC approval indicator “#” can be used as the substrate for applied film layers
- The glass layers used as the substrate for the applied film can be tinted or coated as long as the coatings do not face the applied film
- Only the layers of the Type “Applied Films” in Optics5 that have a “#” on them and are also on the “Applied Films Measured with Clear Glass” list can be used
- not all films have “#” yet, but most probably will by the time this procedure is implemented
- Some films in the “Films” category will be moved to the “Applied Film” category

## Applied Film Verification

- Glass Layers with an applied film constructed by simulators in Optics5 will not have a # next to them.
- Future versions of the WINDOW software could determine if the applied film layer was constructed from NFRC approved # layers, and report/display this information.
- The simulator shall specify in simulation reports the applied film and the substrate, which shall all meet the # criteria, such as:		**2802 / 5038**** **
- The simulator shall provide the properties for the applied film layer (from Optics and WINDOW5 Detailed Report in Glazing System Library), including:
- 		Tsol, Tvis, Rsol 1 & 2, Rvis 1 & 2, Emissivity
- An IA (or anyone else wanting to check the results) can recreate the applied film layer from the specified film and substrate and verify the calculated values
