TMW 250,
450 & 453
Strip & Ribbon Systems

This family of thermally broken products features screw spline construction for simpler fabrication and erection. Each product is inherently versatile as they can all be either exterior or interior glazed. In their EFG designation either product can accommodate two-sided structural glazing. TMW 250 and 450 feature a 2" profile, while 453 is 2 1/2".

TMW 250 is best suited for ribbon window and storefront applications, while TMW 450 and TMW 453 are ideally suited for curtain wall applications where the benefit of the I-beam mullion design comes into play.
