More about this product

OTTOSTUMM supplies components for steel fenestration systems. OTTOSTUMM’s thermal barrier sliding door systems are suited for larger frame dimensions and weights, which are outside the ordinary. The profiles are available in steel, cor-ten steel, and marine-grade stainless steel AISI 316L.

The code “MLS72 TB” stands for an extensive family of thermal barrier lift and slide door solutions. The profiles are cold-formed with 2mm thick steel making them ideal for large glazing with weights up to 600 kg. The 72 mm profile depth is a balance between design and security. The extremely strong framing material accommodates security glass up to 50 mm and can be automated.
