Robust and Elegant Casement Windows

In home construction and renovation, the durability of windows is non-negotiable. They serve as the primary barrier against external elements, ensuring that the interiors remain comfortable and energy-efficient. Windows also play an instrumental role in home security, preventing unwanted intrusions and ensuring peace of mind.

Given the significance of these roles, opting for a trusted provider is essential. At Sash Windows London, we have established ourselves as a distinguished provider of timber casement windows. With an unwavering commitment to quality, weโ€™ve consistently delivered products that combine visual appeal with robust construction.

The Timber Advantage

Timber, as a building material, boasts innate qualities that have made it a preferred choice for centuries. At Sash Windows London, we make use of engineered Redwood and engineered Red Grandis:

Engineered Redwood

Engineered timber consists of impeccable sections of European Redwood. These sections are bonded, compacted, and layered with alternating wood grain directions. This grain alteration in Redwood enhances its structural stability, significantly reducing the likelihood of deformation from swelling and warping.

This makes it particularly suitable for crafting timber windows and doors. The Redwood used is responsibly harvested from Northern Europe and holds an FSC Certification. It’s tailored specifically for joinery tasks, making it an excellent choice for window and door fabrication.

Engineered Red Grandis

Grandis stands out among other timbers in the industry due to its diverse advantages, ranking as one of the finest hardwoods available today. Boasting qualities akin to oak, Grandis is a top-tier hardwood renowned for its distinct markings and unparalleled durability. In its untreated form, the wood showcases a deeper and more intricate grain, making it ideal for those seeking a lacquered or stained finish.

A Guarantee You Can Trust

At Sash Windows London, we donโ€™t just craft windows; we build trust. Every window we design is a testament to our dedication to quality and longevity. That’s why we confidently offer an unparalleled 30-year warranty against timber rot and decay.
