Modern design: Optima combines the best trends in the door industry, including minimalist style, quality materials and versatile shade. Pure Flush construction will favorably highlight the advantages of the surrounding interior while remaining a self-sufficient and striking element of home design.
Door construction: the door is strong and durable due to a solid pine door frame.
Door filling: engineered solid core is an innovative eco-friendly wood fiber material with 12.5 lb/ft³ density. It is responsible for soundproofing and keeping heat inside the room.
High-quality finish: the slab is coated with polypropylene Gray Matte, an environmentally friendly material resistant to moisture and temperature fluctuations. The door with a PP finish is easy to care for, so it is enough to use a damp cloth without aggressive deterge when cleaning.
Warranty: 2 years.
Easy door hanging: EZ-Hang is a unique seven-bracket door installation system that can be used at any stage of construction, eliminating the need for shims. With this patented technology, hanging an interior door is five times faster. The advantage of the EZ-Hang is that the attachment is adjustable: there’s no requirement to bend or alter the bracket, and it is suitable for either or both sides of the door, with or without drywall.
