Early Georgian windows featured thick glazing bars and little panes of glass (typically a "six-over-six" configuration) due to the fact that big sheets of glass were technically impossible to produce. As the era advanced and glass-making strategies improved, glazing bars ended up being thinner and more stylish.

For centuries, wood was the undeniable king of window building and construction. However, the 20th and 21st centuries have actually introduced brand-new products that attempt to replicate the look of wood with less maintenance.
Lumber (The Heritage Choice)Hardwood: Oak and Mahogany provide amazing resilience but come at a premium price.Slow-grown Softwood: Often utilized in original windows, though modern fast-grown pine is less durable.Accoya: A customized timber that is becoming the gold requirement for duration remediations.

Nevertheless, innovation has evolved. Vacuum Glazing (such as Fineo or LandVac) offers the thermal performance of triple glazing however is just 6mm to 10mm thick, permitting it to suit traditional thin frames.
Maintenance Checklist for Period Windows
