Construction:

The 1-3/8" thick door sections of Buildmark STS are made from two layers of strong, rust-resistant 25-gauge galvanized steel and are coated with a baked-on polyester paint finish for long life.

 

Track/Rollers:

Track formed from strong galvanized steel, paired with durable, long-wearing steel rollers ensures smooth, quiet operation.

 

Insulation:

Polyurethane insulation fills 100% of the door's interior space and delivers an exceptional 12 R-Value, provides structural integrity, and helps reduce noise.

 

Thermal Protection:

A continuous thermal break (A), prevents heat-loss by eliminating metal-to-metal contact between inside and outside door surfaces. An air seal (B) blocks airflow between sections.

 

Finished Interior:

BuildMark STS features a steel interior backing for a finished appearance and added durability.

 

Section Joints:

Strong, roll-formed tongue-and-groove meeting rails seal out the elements, keeping your garage dry and secure.

 

Exterior Texture:

Authentic wood grain texture on the door's exterior adds visual appeal.

 

Tamper Proof Cable Attachment:

The tamper-resistant counter balance cable attachment cannot be released while the cable is under tension, helping prevent injuries or accidents.

 

 

Weatherseal:

A vinyl weatherseal attached to a sturdy aluminum retainer helps keep out wind and rain.
