Sliding wood windows are almost identical to our double hung wood windows on their sides but without the need for balancing. With the added challenge of the meeting rail; we take pride in providing a super-efficient, contemporary weather-stripping system that stops all air-infiltration while being completely hidden from sight. Like all our sash, our wood sliding windows are available with all the muntin and glass configurations found under our window solutions page.
We offer a variety of glass types in any shape you need including; highly efficient and space saving Spacia Vacuum Insulated Glass, regular insulated glass, monolithic glass, and wavy glass.
There have only been a handful of predominant sash molding profiles from 1865 on. The most common profile and our standard is the “Roman Ogee”, while other profiles are available.
Our use of insulated glass, our own Window Logic weather stripping system, and high quality constant force balancing systems provide the efficiency of modern windows with historical accuracy.
We maintain historical aesthetics by setting glass 7/8″ deep into the sash from the interior to create a shadow line that helps provide character. Most modern manufacturers ignore this crucial detail.
Heirloom Ultima Windows are unquestionably the most historically accurate window on the market with contemporary performance. See how Accoya wood and VIG combine to satisfy both preservationist and conservationists.
Magnum Windows are Heirloom’s original product and identical to the Ultima except the Magnum utilizes standard IG (Insulated Glass) which makes the sash thicker. See why it’s sometimes the best option.
Heirloom Classic windows are the classic historic replica window with either standard double strength glass or even wavy glass. The Classic is the right choice if True Divided Lite construction is required and it is available with or without Heirloom’s proprietary invisible weather-stripping system.
