ASD Fineline Window with ASD Hermetic 50CS Slimline Doors. Fineline is a narrow profile steel glazing system which incorporates the Hermetic 50CS Slimline door system.
The system is not thermally broken, but achieves low U values because steel has low heat conductivity qualities, coupled with the fact that the amount of metal in these frames is very low. The system is slim and elegant and allows extra light into the interior space.
