Bay and Bow Windows

Trimline bay and bow windows enlarge the feeling of space in any room. The bay can be either double hungs or casements with a center picture window. The bow is comprised of three to six casements and stationary windows. Both offer the timeless style and warmth of wood along with its insulating qualities with a tough aluminum clad on the exterior for years of maintenance free durability.
