Windows play an important role in any type of roof, as ventilation of vital parts of a building is typically based on them. They are often fitted in places were maintenance access requires the use of appropriate equipment.

Therefore they need to be durable, weathertight and reliable throughout the entire lifecycle. Particularly the windows fitted in glazed sloping roofs should have special features. Not only should they be openable, but they should also match the remaining parts of the building in terms of appearance, glazing capabilities, and thermal insulation.

KLAR-RW is a state-of-the-art system which addresses ever higher thermal and functional requirements for today’s roofs. The system is the latest addition to the KLAR portfolio of energy-efficient aluminum systems. Windows designed using this system are intended for integrating in roofs based on KLAR-SR50N and KLAR-TT50 mullion-transom systems with an angle of inclination ranging from 3° to 75° in relation to the level. Roof windows come with rafter / purlin axes of up to 2.5 m and weight of up to 200 kg.

The KLAR-RW system provides strong thermal insulation and a wide range of glazing options (from 32 to 51 mm), which makes it ideal for projects where emphasis is put on high energy-efficiency. For this reason, the system comes with unique insulation materials. The specially designed glazing gasket and cover cap provide above-average weather tightness parameters while allowing for seamless fitting of glass infills.

Other benefits of roof windows based on the KLAR-RW system include technical capabilities of fittings. In order to simplify fabrication process, the system uses dedicated clamp hinges, which can be fitted in the last stage of construction. Optionally, in order to increase window dimensions, the profiles may come with standard multi point locking hardware without any impact on the overall weather performance of the design. This also enables the design of manually openable windows (using a handle). At the same time, the system allows for fitting various types of electric servo motors from different manufacturers. As a result, MB-RW windows may form part of a building’s management system.
