Mcr OSO THERM 75 smoke exhaust windows are a family of innovative products that we developed combining our 30-years’ experience in the natural smoke ventilation market with the expertise of the leading European experts in window profile sector. We designed this solution taking into account the requirements of the changing construction market and the expectations of our customers.
We have additionally designed special grooves in the window profiles facilitating quick, non-invasive assembly and adjustment of drive brackets and cable laying in order to maintain the best aesthetic effect. Universal profile and bracket standardisation make the customer aware from the very beginning what the final solution is going to look like, guarantee easy assembly, ensure favourable delivery times and aesthetic values.
