The Classic Frame


– Handmade –

From modern lines to classic proportions, the W20 frame series is as significant contribution of character in any window or door application. Its slender hot-rolled steel profile is a benefit to architects and builders not only because of it’s alluring aesthetic qualities, but also for it’s ability to be utilized for heavy duty residential and commercial applications. The versatility of the W20 series spans from the ability to reinforce individual sections of composite framing systems without diminishing from the thin nature of the frame. Additionally, the W20 series is renounced for its ability to match traditional heritage and Georgian style steel windows and doors with the added capability of accepting much more efficient glazing, thus enhancing the overall thermal performance.

Hardware Collection

Hardware for the W20 series steel windows and doors is tailored specifically to meet the needs of each project. Some suppliers tend to provide identical hardware for all of their products, but we understand that no one style or budget are the same. For this reason, we offer an exclusive selection of handles, bolts, catches, hinges, stays, multipoint locks and cremone sets to maintain the elegant and timeless style of our windows and doors. Custom hardware, hardware finishes and hardware fitment is also available for those projects were detail is of the highest regard.


Quality Glass Selection

In any window, door or curtain wall application; especially heritage style projects, it is essential to utilize the correct glass and maintain a healthy budget doing so. To make this possible, we collaborate with an extensive selection of glass manufacturers, domestically and abroad, to deliver a glazing solution that is best for the desired application. For heritage projects specifically, we offer an exceptional range of leaded single pane or dual pane glass as well as custom stained glass and laminated or non-laminated restoration glass which is designed to meet the most rigorous modern safety codes.
