While many large door applications can use either Wilson's Roll-Tec™ steel sliding or Premier™ aluminum bi-fold door, there are general characteristics that may make you favor one over the other. Either way, you'll get great value for your investment.

For ultimate flexibility in architectural detailing on doors up to 120' wide, or where space is tight, Wilson Premier™ aluminum vertical bi-fold doors provide any look you're after in a door that provides the lowest lifetime ownership cost in the industry.

For extremely wide door applications where cost is critical, Wilson Roll-Tec™ steel bottom rolling doors are probably your best bet.

Finally, some jobs just beg for the lowest possible installed cost. For a reliable bi-fold door that provides incredible value at prices you wouldn't think possible, consider the Wilson Valu-Tec™ door. Hey, "Value" is its middle name.
