Comparison Summary at a Glance

Series	Material	Best For	U-Factor	Price Point
100	Fibrex Composite	Durability & Value	0.27 – 0.30	$
200	Wood / Vinyl	Entry Wood Look	0.28 – 0.32	$$

A-Series	Wood / Fiberglass	Efficiency	0.22 – 0.25	$$$$

Pro Tip: U-Factor measures how well a window prevents heat from escaping. The lower the number, the better the insulation. For our local climate, we recommend a U-Factor of 0.30 or lower.
