TM220 Features and Options

Raynor ThermaSeal TM220 commercial doors are available with numerous features and options, including those listed below.

Maximum Thermal Protection

Energy-saving polyurethane foam insulation is used to deliver exceptional R-values.

Rugged Hardware and Springs

Your ThermaSeal door comes packaged with the right combination of long-lasting hardware, track, and springs to precisely match your door’s size and application.

Reduced Airflow

Dual vinyl barriers dramatically reduce air infiltration. A true thermal break prevents heat loss and eliminates any metal-to-metal contact between surfaces.

Decreased Energy Costs

ThermaSeal doors help you reduce energy costs with a U-shaped, vinyl bottom weatherseal and sturdy aluminum retainer.

Choice of Windows

Select either 24″ x 8″ (shown), 24″ x 12″, or 34″ x 16″. ThermaSeal doors are also available with aluminum fullview window sections. Choose from a variety of insulated glass, acrylic, tempered and polycarbonate styles to suit any application.

High-cycle Counterbalance Systems

For reliable operation in high traffic areas, choose high-cycle torsion springs with 25,000, 50,000 or 100,000-cycle life.* For reduced maintenance and ultra-smooth operation in heavy-use applications, choose a weight counterbalance system. *Some options may be limited to door size or model.

Customized Track and Hardware Systems

Track systems are supplied to fit special clearances, inclines or contour applications. Hardware and track systems can be designed to fit any need. Additional trussing is available for special wind loading applications. A QuikClip™ pre-assembled track option is also available.

Secure Locks

In applications where control and access are important, choose from a variety of locking options to help keep your building secure. Locks come in both inside and outside variations.

Carbon Monoxide Vent

Allows you to channel fumes to the outside when the door is closed. Available in a variety of sizes.

Removable Center Posts

Carry-away and swing-up options are available for extra-wide openings. Ideal for agricultural or airplane hangar applications.

IECC Requirements Package

The International Energy Conservation Code (IECC) requires building components to meet minimum U-factor and Air Infiltration rates. This option will ensure the TM220 will exceed the latest IECC standards by using the required header and jamb seals and track mounting. Windows, exhaust ports and pass doors cannot be used. Raynor’s IECC package yields the following results:

U-factor: 0.19 Air Infiltration @25mph: 0.12 cfm/ft2
