Quality and choice
Aluminium profiles offer flexibility in window proportions and larger glazed areas. MB-86N SI, MB-79N SI, MB-70HI and MB-70 include thermal breaks; MB-45 is selected where thermal insulation is not required. The final choice depends on the construction and building requirements.

Selection and installation in Vilnius
A choice for your building
Select an aluminium window for its location and construction size. An exterior window for a heated room and an internal partition need different solutions.
An individual quotation
Construction size, system, thermal break, opening type, glazing and finish determine the price. Fixed glazing and an opening window can have different costs even with similar areas.
