Exploited Green Roofs: The Technology of Installation
In the age of rapidly growing metropolises and large cities, where the land prices constantly soar, the developers and the owners of buildings are trying to make the best use of the available space. Therefore, in their architectural projects designers increasingly use schemes that involve accessible roof areas, which do not only protect buildings from the poor weather conditions but can also be used as a public space with green areas for relaxation and various events.
Green roofing is a design solution for coating with planted land: lawn grass, shrubs, flowers, moss, etc. It can be combined with terraces that have hard surface (decking, modular boards, etc.).
Green roofing is divided into 2 categories:
- Extensive green roofs that only have grass sods or other plants. They have limited walk-in accessibility;
- Intensive green roofs or solid roof-gardens with free access for everybody. The Buzon-Russia Company specializes in the construction of accessible green roof areas. Thanks to the variety of the suggested design solutions one can take into account all customer’s preferences. It gives way to a wide range of possible applications of green roofs: from a simple lawn to a real roof garden. Such roofs are adjusted to all types of buildings: industrial sites, office buildings, apartment blocks and individual houses.
Arguments in Favor of the Use of Green Roofs:
- Protection of the waterproofing layer (base roofing) from overheating and ultraviolet radiation;
- Air temperature pulldown during summertime;
- Additional thermal insulation of the building in winter;
- Reduction of air pollution, absorption of dust and hazardous substances;
- Increase of noise and sound insulation;
- Prevention of hazardous substances and volatile compounds that are produced in bituminous roofing material;
- Prevention of rapid fire spread over the surface of the roof in case of fire.
THE CONCEPT OF GREEN ROOFING ON THE ADJUSTABLE BUZON
pedestals Before the roof becomes comfortable for people to stay on, a set of preparatory measures have to be performed in order to avoid possible issues in the course of its operation. Roofing work requires a very serious approach - it is necessary to carefully check the condition of the waterproofing layer prior to the green roof installation. One should take into consideration the significant impact that microorganisms, chemicals and root system of plants have on it.
The support of a green roof should be strong enough to keep the weight of the soil layer and the weight of plants as well as to be able to withstand wind and operational loads. Given that plants constantly need watering improved waterresistance and very low moisture absorption are also important characteristics of the exploited roofing.
There are various ways to construct flat roofs, but most of the proposed technologies are deterring due to their complexity. The Belgian company BUZON offers a modern building system that is imbued with the accumulated experience. It is a set of vertically adjustable BUZON screw bearings and terrace top layer. To date, this is the most efficient system to construct an accessible roof area. Its main advantages are the reduction of the load on the roof, little construction period and ease of maintenance during operation.
BUZON supports allow the constructors to set the desired height of the coating and give it a strictly horizontal position (or the necessary slope if required). There is free space between the coating and the base roofing that helps to avoid excessive mechanical loading on the waterproofing layer as well as to ensure an easy access for maintenance and repair. BUZON supports provide constructability, flexibility and ease of installation, which allows the constructors to apply them to roofing surfaces of various configurations on one or several levels.
BUZON adjustable supports interconnect separate elements of the coating in such a manner that no additional mounting to the base surface is required. With its convenient screw connection the required height is easily aligned for subsequent log installation. This contributes to the fast and high-quality work. Terrace boards are mounted by means of clips with the interpanel clearance being respected. It is necessary for free drainage. Therefore, when falling on them water freely flows down. Cleaning is simplified to a single action – removing dirt with a high-pressure water hose. The air freely circulating under the coating surface contributes to its quick drying. With the BUZON adjustable screw bearings one can solve all technical issues related to the construction of an accessible roof area.
