Our Simpson Exterior Doors collection has the widest range of wood and window meshed pieces around. Our door designers here at Trimlite know what a lot of their customers want in a new door. That’s why they created this Thermal Sash Door, specifically this 7508 Fir Simpson Exterior Thermal Sash Door. They know that people like doors that bring natural lighting into the room, in addition to keeping their internal precious possessions safe. The cloudy finish of the window on this wood piece does just that, with the addition to the complete Fir bottom half. If this design fits your needs, order it and several others today.
