Razmyishlenie about a roof. Companies Ursa and Braas DSK-1: modern roofing materials and systems

The rational approach to use of available inhabited space defines necessity of careful selection of materials and the systems supplying viability of a structure.

Let’s address to a question on a roof as optimum use of garret space directly depends on quality of roofing system and from the materials used in its system.

So, you have decided to use space under skatnoy a roof, having transformed an attic in high-grade premises. Realisation of this decision is interfaced to some complexities. The penthoue roof executes function of an outside protecting wall: it should protect a premise from a cold in the winter and from a heat in the summer. Hence, the roof should be warmed.

It is a multilayered design where interaction of each layer of a roofing pie supplies its reliable work and durability as a whole.

In a cold season warm damp air from a mansard premise because of pressure difference outside and inside aspires to leave outside. Thus the water steam containing in air, being condensed in a roof design, can humidify its inside layers with dewdrops. This formed in thickness of a design a moisture can deliver a great deal of trouble.

The method of successful struggle against a condensate is found for a long time and successfully applied – the design of the warmed slope should be ventilated.

From a warm premise the steamproof barrier to air is put and forms konvektivnyiy an air stream in a design of a slope of a roof: from eaves upwards to the fad so that parts of a condensed moisture were carried away with this stream, not humidifying a design.

The modern warmed roof, as a rule, consists from stropilnoy systems, podkrovelnoy waterproofings, an effective heater, paroizolyatsii and a penthouse material for processing. How correctly to choose and combine its elements?

Roofing system BRAAS

Let’s begin with a choice of a roofing material and we will stay on a natural tile – an ideal material for a roof paving. She does not require working costs, does not accumulate a static electricity, harmoniously combines the form, colour, the invoice.

The roof from a natural tile maintains a gale-force wind impact. Thanks to massiveness the tile extinguishes rain noise; its rigid, high-strength armour laid on reechnoy obreshetke, does not require the system of the continuous basis. Reconstruction of a tile roof will not make the big work. Casual damages are easily eliminated in view of interchangeability of elements.

All told to the full concerns both to ceramic, and a cement-sandy (concrete) tile.

Made in Moscow at the joint germano-Russian enterprise «BRAAS DSK-1» the cement-sandy tile has the European degree of quality. Production corresponds to the German and Russian standards and in a combination with dobornyimi the elements delivered from Germany, supplies reliable roofing cover skatnoy roofs of any complexity at corners of an inclination from 10 to 90 °. The Billing period of its operation makes 100-150 years at the factory warranty of 30 years.

«BRAAS DSK-1» offers also a ceramic tile – natural and glazurovannuyu the several colours, made in Germany. Tens names dobornyih elements form harmonous roofing system in which all basic knots and the interfaces meeting at the system of roofs of various architectural forms are thought over and structurally decided. Dvuhskatnyie, valmovyie, schiptsovyie, tent, mansard and any other roofs with acoustical and mansard windows – all it with success can be executed with application of roofing system BRAAS on the basis of a natural tile.

The major dignity of roofing system BRAAS is that she allows to avoid destroying action of the condensate formed in thickness of the warmed roof.

Podkrovelnaya a waterproofing

In "stuffing" of a roofing pie, except the basic roofing cover, the additional layer podkrovelnoy waterproofings in the form of a strong synthetic film enters.

Depending on an applied material podkrovelnoy waterproofings distinguish two types of ventilation: two-layer and single-layered.

In a design of a roof with two-layer ventilation (fig. 1) the waterproofing film is established with a backlash under the relation both to a roof, and to a heater, forming two air cavities for free movement of air from eaves to the fad. At such constructive decision the moisture which has got under a roof, will flow down on a film, and skondensirovavshayasya the moisture will disappear an air stream, draining a heater and obreshetku. In this case it is impossible to suppose, that the film concerned a heater, differently the condensate formed on it will humidify a heater.

At the system of two-layer ventilation eurofilm Eurofol Q140 (BRAAS), URSA SECO STORM (URSA), YUtafol D110, YUtakon N 140 (JUTA) can be applied. Paropronitsaemost these films does not exceed 25 g/m І, 0,33 g/m І, 49 g/m І and 0,35 g/m І for 24 hours accordingly.

With single-layered ventilation (fig. 2) the waterproofing film keeps within designs of a roof directly on a heater. It is possible only in the event that it paropronitsaemaya superdiffuzionnaya a membrane not passing an outside moisture and freely passing steam from a heater (paropronitsaemost for days 750-1000 g/m І).

Paropronitsaemyimi superdiffuzionnyimi membranes are films Diforol About (BRAAS), URSA SECO 1000 (URSA), YUtavek (JUTA) with paropronitsaemostyu 1200 g/m І, 1600 g/m І and 1200 g/m І a day, accordingly.

Paroizolyatsiya

Paroizolyatsiya it is intended for creation of a steamproof barrier on an internal surface skatnyih roofs and promotes long preservation of properties of a thermal protection, interfering with penetration of water steam from internal space of a penthouse in building designs of a roof.

These are films URSA SECO 400, URSA SECO 500 (URSA), YUtafol N110 (JUTA) with paropronitsaemostyu 18g/m І, 0,31g/m І and 0,9g/m І for 24 hours accordingly, and also the aluminium foil pasted to teploizolyatsionnyim to floor-mats or plates URSA.

Systems of thermal protection URSA

The modern roof assumes use effective teploizolyatsionnyih materials. Such materials concern teploizolyatsionnyie items from glass shtapelnogo the fibres of mark URSA manufactured in the form of soft floor-mats and plates.

Company URSA is a part of concern URALITA – one of leaders in the market teploizolyatsionnyih materials in Europe. In Russia URSA has two factories on production teploizolyatsionnyih items from glass shtapelnogo fibres, a network of regional representations and warehouses that allows qualitatively and in short times to serve clients.

For warming skatnyih roofs the company represents wide range high-quality teploizolyatsionnyih materials.

Low heat conductivity and high air permeability of items URSA allow to reduce heat losses considerably. Application of easy floor-mats and plates URSA reduces weight of designs skatnyih roofs and load on the bases of buildings.

For warming skatnyih roofs it is recommended to use teploizolyatsionnyie floor-mats of marks M-15G, M-17G, M-25G or plates P-15G, P-20G, P-30G. Depending on constructive decisions it is necessary to apply floor-mats or the plates which have been pasted over stekloholstom for vetrozaschityi or an aluminium foil for paroizolyatsii.

At the system skatnoy roofs special significance acquires correct from the point of view of building physics a combination of materials for each layer. Possibility of diffusion and air permeability are key for creation of a reliable and durable design.

Company URSA offers specially picked up systems of warming skatnyih roofs, both for new building, and for reconstruction of old buildings.

In these systems all components are optimum co-ordinated: teploizolyatsionnyie floor-mats and plates URSA in density of 15-30 kg/m і, waterproofing and paroizolyatsionnyie films URSA SECO, sticky sealing tapes.

Thermal protection systems skatnyih roofs allow to minimise losses of heat and supply the optimum sound insulation, necessary tightness and protection against penetration of water steam, and also fire resistance of a design.

The thickness of a heat-insulation layer depends on climatic conditions of area of building and settles up according to SNiP 11-3-79 «Building the heating engineer».

In average widths it should be not less than 150 mm, in northern – not less than 200 mm.

Thanks to the elasticity, floor-mats or plates URSA fast and easily keep within between rafters. At insufficient height of rafters the necessary thickness of a thermal protection is reached by stacking of additional layers teploizolyatsionnyih materials URSA which keep within between the longitudinal bars attached to rafters from the inside (fig. 3).

Advantages of system of thermal protection URSA:
  • Heat - and the sound insulation meeting the highest requests.
  • Simple and reliable installation.
  • Use of a material practically without waste.
  • The free diffusion supplying durability of a heater and stropilnoy of system.
  • Reliable protection of a design against damages.

    Our conversation on a roof – not instructions «do so» and not directions for use. It only some, is far not complete «the information to reflexion».

    Employees of companies URSA and BRAAS are ready to grant you technical decisions of systems of isolation URSA and roofing systems BRAAS for skatnyih roofs, to make their account and a complete set, to render consulting and building services on objects.
