Kolbe Windows

Kolbe Windows Ultra Series

Wood Species. Ultra Series windows and doors are constructed of Pine (72) as standard, for a stable product that will accept many beautiful finishes.
Construction. From the selection of wood to delivery of the final product, Kolbe meets strict standards for quality construction. For instance, windows are sealed on both sides of the glass. Half-rounds are constructed with doweled joints and turnbuckles at critical stress points for stability. Interior removable wood grilles have a full perimeter frame for stability. Ultra Series frames are screwed at the corners, with silicone to seal corner junctures and screw openings.
Glass. Ultra Series products have H°K dual-insulating glass units with LoE²-270 coating, argon gas, and Thermo-Edge spacers on most units as standard. This helps them to meet or exceed ENERGY STAR® guidelines for energy efficiency in all climate zones.
