SASH WINDOWS
Windows with vertically moving sashes are called "Sash Windows".
Modern mechanisms have made sash windows as practical and safe to use as they have never been before.
Besides being used in period buildings, sash windows are also employed in new residences for the sake of practicality and architectural concerns all around Europe.
A modern mechanism, consisting of stainless steel springs placed in a pipe of 16-26 cm diameter is able to move a 45 kg sash simply by your fingers and to leave it at any position you like.
Historical sash mechanisms, on the other hand, continue to draw attention with many examples still working on period buildings from 19th and 18th centuries. We use high technology spring balances in keeping the balance of sashes at any point of its movement. We also produce timber box sash windows. These are traditional vertical sliders working with weights and cords.
Arbor's traditional weights and cords system offers a reliable and time-honoured solution for vertical sliding sash windows. Using precision-balanced counterweights connected by durable cords, the sash operates smoothly and effortlessly, remaining perfectly balanced in any position. This classic mechanism ensures long-lasting performance with minimal maintenance, while preserving the authentic look and feel of traditional window joinery. Ideal for restoration projects and heritage buildings, the system combines craftsmanship, durability, and seamless functionality.
