Modern wood-aluminum system Duoline is an innovative product which offers perfect durability and elegant aesthetics.The DUOLINE system not only meets the stringent requirements for energy-efficient and passive constructions, but it is also a response to contemporary expectations of customers in terms of modern woodwork.

Outer aluminium cover Mira contour, which is weatherproof and suitable in terms of connecting system, enhances stability and improves windows’ static parameters as well as energy efficiency and sound insulation.

The new, wood-aluminum system has classic, sharp shape of aluminum edges, typical for modern constructions and in line with the latest trends in architecture. The possibility to select pine or mahogany profile and a thickness of 68mm, 78mm or 88mm offers excellent opportunities to create different technical solutions. In standard offer Duoline window is fitted with a one-chamber glazing 4/16/4 with warm frame. However, there’s also a possibility of customization to build a window equipped with up to four glass in one package to ensure even better thermal protection and guarantee a barrier against intrusion, noise or excessive sunlight. The system offers a multiple choice in terms of shapes of the window (from rectangles, trapezoids by, arcs, circles, and other custom shapes) and their colour’ arrangement. Inner part of the window can be made of pine or mahogany and painted with opaque (RAL colours) or transparent colours. The outer part of the window in the form of aluminum covers can be painted with one RAL colour.

Duoline window system is equipped with a single-chamber glass unit. Standard glazing consists of float glass 4 mm thick, the spacer having a width of 16 mm and a thermofloat glass 4 mm thick, while the space between the panes is filled with argon to achieve a lower heat transfer coefficient.

DRUTEX S.A standard glazing package consists of 4 mm float glass, 16 mm spacer and 4 mm termofloat glass whereas the space between glasses is filled with gas- argon, which helps to achieve appropriate thermal insulation value. Standard glazing package increased heat infiltration properties and its thermal insulation value amounts for U=1,0 according to norm EN-674. Moreover, DRUTEX S.A. creates the possibility to choose an appropriate glazing package fully individually, in such a way that it poses even much better protection against burglary, noise as well as excessive insulation.
