Choosing the Right Masterframe Sash Window for Your Home
When selecting sash windows for your home, Masterframe offers two standout ranges—Authentic and Bygone. Both collections combine traditional design with modern performance, but each has unique benefits depending on your needs.
Authentic Collection
Designed for homeowners seeking to maintain a classic look without breaking the bank, the Authentic range replicates period sash windows with features like run-through horns, slim sightlines, and deep bottom rails. Made from high-quality uPVC, these windows provide the appearance of a period sash without the upkeep, offering durability and weather resistance. ‘A’ Energy Rated as standard, the Authentic range balances tradition with cost, making it a great choice for homeowners who want classic aesthetics and modern comfort but on a stricter budget.
Bygone Collection
For those seeking the highest level of period authenticity, the Bygone collection is the premium option. These windows feature handcrafted joints, putty-line detailing, and slim frames to perfectly replicate original timber sash windows. Ideal for conservation area properties or those wanting a truly heritage finish, the Bygone range offers vacuum insulating glass for superior insulation and an A++ energy rating. Additionally, with Secured by Design certification, these windows provide enhanced security without compromising on the traditional look. Customisation options abound, from bespoke colors to Georgian bar patterns and traditional hardware.
Conclusion
Both the Authentic and Bygone ranges offer beautiful sash windows that complement period architecture while improving energy efficiency and security. The Authentic collection is a great balance of tradition and practicality, while the Bygone range offers unmatched authenticity and premium features for those who need a closer match to historic timber windows.
