Using modern tooling, the Grange TG is manufactured with traditional sash sections modified for thermal glazing, and can be supplied with interior and exterior muntin bars to match a wide variety of applications. The traditional construction and appearance of this window make it ideal for restoration work or new buildings, especially in heritage designations where a historically accurate replacement is required for existing single glazed windows, but improved R-value, soundproofing, weathersealing, and other benefits of modern windows are desired. The Grange TG (and SG) are unique among Double French Casement designs, using a concealed astragal that eliminates the need for a center mullion.
