Low threshold


The THERM threshold is a special solutione designed by FINESTRENURITH for the fourth side of the windows: it is a low threshold made from aluminium, allowing for a reduction in spaces and therefore limiting the architectural barrier, and almost guaranteeing the same levels of performance as the fourth side in PVC.



Designed for the MD76 range of windows, the THERM PLUS threshold adapts perfectly to the special shape of the profile frame with three gasket, the main feature of the MD76 range of windows.

Excellent levels of thermal performance are also guaranteed for this solution.
