Timeline's NFRC Technical Data.



Glass is undeniably the most thought about, debated and prevalent component of a window or patio door. Timeline uses double strength (or thicker) glass on every product we manufacture. Heavier glass is more resilient to stress cracks and seal-failures, the leading cause of glass issues. Quality fenestration products always have double strength glass-Lincoln always has double strength glass.

Combined with warm edge spacer technology, our glazing systems start showing their true potential. An insulating glass unit (glass, spacer, glass) has a significant influence on the energy performance of the total window. This important factor is why Timeline offers several different glazing choices. Glass can be clear insulated, LoĒ², LoĒ³-366™/Neat®, triple-glass or multiple obscure, tinted and laminated choices. The newest option, Dual Low-E, combines a pyrolytic LoE to surface four and is combined with LoĒ² or LoĒ³-366™/Neat®.
