Front or Back Glaze

The T14000-IO Series Storefront Windows provide customers with the same quality standards found in our door products. This front (or back) glazed system is recommended for low rise exterior applications and is commonly used with secured vestibules.

The T14000-IO system is aesthetically pleasing since the glass is glazed towards the outside of the building. This gives the storefront a high rise look for first and second floor applications.

These storefront windows utilize 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 entrance system.

Cross Aluminum T-14000-IO 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.
