Hardware — we took every detail into consideration. Even our handle is subtle yet functional. The handle color is satin brushed nickel, and is recessed flat with the panel. This gives the door that very sleek and modern appeal yet functions extremely well. The lock is a multipoint locking system to provide added security. All doors come with a standard external keyed locking system.

Roll-Xtreme — features 14 precision stainless steel 5mm ball bearings. These Swiss bearings enable the large panels to glide effortlessly and handle a larger sized panel with ease.

Quite simply the Roll-Xtreme is the best on the market. Over the past 50 years, other window companies have come and gone. Sure, there are still a few good ones.

At International Window, quality is our trademark. That is why we leave nothing to chance. We use quality vinyl in all of our windows and patio doors. Each product then undergoes rigorous testing to ensure its adaptability to changing climatic conditions.
