Since the buliding is a protected cultural property a complete process was under the control of a conservator from the Institute for the Protection of Monuments of the City of Zagreb.

Roof cover replacement of the residential building - Vlahe Stulića 12-20, Zagreb

Residents of the building in Špansko decided to replace worn-out roofing made of asbestos-cement boards with a new roof cover using trapezoidal galvanized sheet metal with felt. Simultaneously with replacement of the roof cladding we replaced the entire roof metal ware (chimney flashings, sheet metal washers, wall claddings, gutters and verticals). What was so special about this project was the fact that day to day work was realized using a telescopic work platform. From this platform, the following activities were completed: replacingmansard roof coverings, painting of existing hooks, replacement of gutters and verticals. Roofing material used was trapezoidal metal sheet from Fhili Stahl manufacture, with a 15- year warranty. It is worth noting that we also provide contractual guarantee for the same period, for all works completed.

Creating new roof construction and ventilated roof - Ferenščica, Zagreb

Family from Ferenščica- Zagreb received a subsidy from the Environmental Protection and Energy Efficiency Fund, to install a thermal envelope to the house. The envelope was made using 12 cm thick panels of graphite expanded polystyrene (EPS). This meant 20% better insulation than the one made of white EPS panels with equal thickness.  At the same time it was decided to raise the height of the attic in order to reduce the pitch of the north side of the roof and to build dormers, i.e. a mansard roof. Following the dismantling of roof tiles and re-tailoring of one part of the existing roof construction, new roof structure was built. After that, classic ventilated roof was built and covered with formerly removed clay tiles. The result was a beautiful, energy efficient "cottage surrounded by flowers" which offered sufficient living space for this family of four.

The scope of completed works: roof-147 m2, facade- 156 m2

After that, on the flat roof a layer of thermal insulation boards XPS was set, then the divider / protective layer of geotextile, while on horizontal surfaces and parapet wall, a new roof isolation was carried out using Sika waterproofing membrane and also new drain traps and vents were installed. Details of completion of the new waterproofing HI membrane at flat roof parapet walls were done using the PU membrane Sikalastic 621 TC.  On the top of waterproofing system a layer of artificial grass was installed.
