Understanding the 80mm Resurgence system's key features and their benefits
Choosing the right PVCu window and door system means understanding the details that impact performance, appearance, and longevity. Below, we break down four essential features that define quality and design in Liniar’s 80mm flush sash Resurgence system.
What Is a Flush Sash?
A flush sash window or door is designed so that the opening sash sits level with the outer frame, creating a sleek, flat finish. Unlike regular casement windows - where the sash sits proud of the frame - a flush sash offers a streamlined appearance.
This design is particularly popular in heritage-style properties, as it can replicate the look of traditional timber joinery while delivering the low maintenance, durability and thermal efficiency of PVCu.
However, by choosing more contemporary colours (such as blacks or greys), a flush system is equally suited to delivering a modern, architectural appearance.
What Is a Double Rebate?
A double rebate refers to a window or door design that features two sealing points between the sash and the frame, rather than just one. This means there are two layers of protection working together to keep out draughts, water, and noise.
The benefit is simple - enhanced performance. Resurgence’s double-rebated design features our patented bubble gasket and provides improved thermal efficiency, helping retain heat within the property, and delivering greater weatherproofing. The enhanced seal integrity also contributes to better acoustic insulation, making it an excellent choice for homes in busy or exposed environments.
What is ‘through foiling’?
Through foiling is a term describing how the foiled finish on the framework is wrapped around all visible edges. This method creates a consistent surface from every angle, delivering a more premium appearance and realistic timber-styling, even when windows and doors are open.
Different Joint Options
The way a frame is joined at the corners plays a crucial role in both strength and visual appeal. There are three main types:
Mechanical Joints
Mechanical joints use brackets or fixings to connect the frame sections. They are commonly used to replicate traditional timber window construction, making them ideal for heritage applications. The key advantage is authenticity in appearance, without compromising strength and performance.
Welded Joints
Welded joints are exclusive to PVCu material and are created by using heat to fuse the corners, forming a strong, weather resistant bond. Welded frames are highly durable, low maintenance, and cost-effective, making them a popular choice for modern installations.
Timberweld® Joints
Timberweld is a more advanced technique that combines the benefits of welded joints with the refined appearance of traditional timber joinery. The weld is carefully finished to mimic the look of a mechanically jointed frame, offering the best of both worlds.
Homeowners benefit from superior durability without compromising on aesthetics, making Timberweld an excellent option for those seeking both performance and authenticity.
By bearing in mind these points, you can configure your Resurgence windows and doors to meet your exact requirements.
