This contract not only includes the replacement of the windows, but also the internal window sill, which shall be replaced with a new one. This replacement will involve construction activities that are included in this contract. Additionally, after the new window is installed, the contractor shall paint all surfaces around the windows to hide any evidence of construction.

Materials for New Windows:

New windows are to be made of highly valuable PVC five chamber profiles that must be of certain thickness (min. 3,5 mm) and with reinforced galvanized steel profiles. Profile should be fully in compliance with RALA quality standard.

Coefficient of thermal conductivity of profile package with metal reinforcement (according to DIN EN 12412-2) less than 1.4 W/m2K). Filling should be double layered glass IZO /20 mm/ (double flat transparent glass with a vacuum between, d=4+12+6 mm).

Inner glass is low emission – LOW E – 1,1W/m2K while the outer is classic - FLOAT.

Sealing is to be done with epoxy rubber (in line with EN410 and EN 673 , Ug=do 2.0 W/m2 K).

Joinery to be supplied with high quality replaceable seals, high quality shackles based on nickel and AL alloys, handles, doorknobs and keys.

All PVC joinery is to be done in line with schemes, in white color. The plan is to have natural flow of air when windows are closed, through especially constructed elements in the frame of the window, type Regel Air, or in some other way, in line with DIN and EU norms. Number and size of elements depends on the size of the window - minimum of two units. No elements should be put in fixed windows and over-lights. Windows should be tightened with wall screws depth 50 mm.

Sealing between wall and window frame should be done with polyurethane foam. Quality certified shackle should enable opening in line with the provided scheme. On the outer side, set an outer bench made of prefabricated aluminium profiles. They are set in the whole width of the window and light box in the prescribed bleed around current facade walls, including the intervention on the facade - the bleed should be six cm more than prescribed bleed. When installing exterior window sill, the sides must lean on the wall, and the part of the facade that is damaged must be fixed. The sill should be tightened with at least two screws in the field. They can be direct or indirect. On the interior side, place parapet benches PVC profile in white color, all in line with producer specifications and joinery schemes.
