The thin lines and historic appearance of steel windows is quite popular now. Instead of accepting a non-thermal, locally made iron window or door, we suggest you consider one of two alternatives we offer. The first is the high-end, thermally-broken steel window made with profiles from the Italian firm Secco. This product has U-values similar to a wood window but can be made in breathtakingly slim profiles. The second option would be a clad window with a thin frame and thin muntin bars designed to create the look of steel at a fraction of the price.
