Dear Mr. Pavcek,
Please accept this letter of confirmation that product selected* for the above referenced project will meet the NFRC
performance requirements as set forth in the previously submitted National Certified Testing Laboratories test report
NCTL‐110‐14134‐01 dated September 28, 2011.
* Dual Glazed K32/60/7 Standard Cast over K32/60/7 Standard Cast channel glass with 25mm Lumira insulation in the
K60 series thermally broken frame system. U value: 0.27.
The product design, materials of construction, and sourcing have remained unchanged. It should be noted that while
the required minimum insulation thickness to achieve this U‐value is 20mm, TGP supplies the Lumira insulation in 16mm
and 25mm nominal thicknesses; with the latter being the selection required to reach the desired value.
Sincerely,
Ron Madeley
Principal Engineer
