4 ½” Thermal Aluminum Storefront Framing Systems


4 ½” Thermal Aluminum Storefront Framing Systems

Standard and High Performance Thermal Options
Glazing infills 1/8" up to 1-1/8"
Dual Finish Inside/Outside

The T14000 series aluminum storefront framing system provides customers with the same quality standards found in our door products. This center glazed system is recommended for low rise exterior applications and is commonly used with secured vestibules.

This storefront utilizes Cross Aluminums’ heavy duty doorstop allowing parallel arm closers to be mounted with no worries of it pulling out of the frame header. Furthermore, this frame will only use closed backed tubes at every door opening, enhancing the structural strength and longevity of the whole entranceway.

These aluminum storefront frame types are available in Non-Thermal, Thermal, and Ultra Thermal options. They accept 1-3/4” and 2” thermal doors with dual finish options also available.

T-14000 Cross Aluminum Storefront

Secure anchor

Cross Aluminum will only supply closed-back extrusions at every door opening.  This allows for the frame to be securely anchored to the building without product deformation.  Industry standard open backs could deform and not allow snap-in door stop to engage or the door to sag when using side lites.

Cross Aluminum T-14000 Heavy Duty Door Stop Comparison

Heavy Duty door stop

Our heavy duty door stop was introduced as a means to deal with a couple common problems after doors are installed. The taller height allows for a better seal around the door opening perimeter. Furthermore, the thicker wall provides the strength required for closer parallel arm brackets and rim strikes to be mounted worry-free for years after installation.

World Class Quality. Full range of finishes and colors.

Anodizing aluminum is an electrochemical process that oxidizes the material. This provides a protective layer around the aluminum. Anodizing allows the finished products to be corrosion resistant and maintenance-free for years. Cross Aluminum only utilizes the Acid Etch Anodize process in order to improve product finish quality and color consistency. Furthermore, acid etching can reduce up to 90% of the aluminum sludge and waste used in typical caustic etch anodizing processes.


Simplicity at its finest. Secure Glaze Technology.

Cross Aluminum has always distinctively designed glazing to enhance the structural strength of the door. Every glazed entrance at Cross Aluminum will come with a secure non-removeable exterior glass stop.  Glazing kits are unacceptable and compromise the strength and security of any entrance, that is why our glazing is incorporated as part of the structure of the door. Furthermore, all glazing parts will match the finish of the door, unless specified otherwise.
