Roto’s Perfect Match Between Hardware and Weatherseals 

Windows and doors equipped with high-quality hardware and weatherseals improve the energy efficiency of buildings and guarantee high operating convenience. This is why Roto Frank Window & Door Technology (Roto FTT) not only offers window and door hardware, but also effective weatherseals for all opening types.  

With the acquisition of the Deventer Group in 2016 and the US-based company Ultrafab, Inc. in December 2022, Roto became a world-leading supplier of weatherseals for windows and doors. The shape of the weatherseals, its high-quality raw materials, and the perfect match between the weatherseals and hardware offer excellent impermeability even in strong winds and heavy rain. In addition, windows and doors can be easily operated when hardware and weatherseals are matched for the respective application. Roto adapts its hardware and weatherseals to customer’s needs so their doors and windows meet the required security and impermeability performance standards. 

Window and door manufacturers working with Roto hardware and weatherseals benefit from consultation on both product groups. This is also corroborated by the Canadian window and door manufacturer, Kohltech, who have been using Ultrafab weatherseals and Roto hardware for many years.  

Ultrafab’s high-quality weatherseals are designed and tested to customer specifications. The company is considered a technological leader, offering technical support to customers at an early stage of their product development. They provide consultation if unique designs are being developed or if manufacturing processes need to be made more efficient. 

Customers can have their window and door systems undergo a performance test in Roto test centers, as well as test the efficiency of newly conceptualized weatherseals at Ultrafab. All tests are carried out in accordance with the latest national and international standards and guidelines. 

Our representatives will be at the Roto FTT booth (303/304) in Hall 1 at Fensterbau Frontale 2024 to provide attendees with information about our weatherseals and manufacturing options.
