LEADER window and Accoya

ACCOYA | Welcome in the future of the wood

Accoya® is a new exceptional variety of timber with performance that makes it ideal for outdoor applications. This wood is produced with sustainable raw materials and managed in an optimal way, it is not toxic and it is also endowed with dimensional stability and durability able to surpass those of the best hardwoods. Accoya is the result of over 75 years of research and development: its high performance is due to the combination of a proven treatment technique, acetylation.

CUSTOMIZATION

make your window unique, customize it to your taste.

English style.

For those who love the colonial style on the Leader window it is possible to overlap the transoms on the glazing. What makes the difference is how we assembly the spacer between glass in correspondence with the wooden transoms. So as to get a greater realistic effect without renouncing the performance of the single glass.

Plinth.

3 lower crosspieces are installed as standard. But you can decide to customize your Leader Window, adding or deleting them. Increase the brightness of the rooms or simply customize it.

Drip.

The standard drip installed on the Leader window is in extruded aluminum. Its aerodynamic shape is specifically designed to facilitate the discharge of water. On request it is possible to equip the window with a solid wood drip.

Tricoat hardware.

The use of hardware with tricoat treatment guarantees perfect operation of closing and opening of the sash. Mounted as standard on all windows produced by Sidel, tricoat treatment is guaranteed for 15 years against rust formation. Perfect in very humid places or near the sea, it is also useful to avoid corrosion that also occurs due to the humidity present in the air.
