Definitions

• the invention relates to a roof insulation system with an insulating element consisting of heat-insulating material, esp. In the form of an insulating board, and at least one arranged on at least one side of the insulating element and heat radiation reflecting reflective layer.
• insulating materials For the insulation of roofs, such as pitched roofs, with a roof pitch of 15 ° or more different types of insulation materials are used.
• the insulating materials can be laid between, under or on the rafters of a roof truss. To achieve the desired insulation values, combinations of corresponding insulation systems are also possible.
• Preferred insulating materials in the roof area are, for example, polystyrene hard foam, mineral wool, rigid polyurethane foam or wood fiber insulating materials.
• the known insulation systems provide adequate thermal insulation with appropriate insulation thicknesses. However, this is usually accompanied by a heating of the interior to be insulated in the summer.
• reflective films such as metallized films or webs with low emissivity, in particular. Block the passage of long-wave heat radiation and thus inhibit the heat flow proposed.
• reflecting foils likewise in the form of metallized foils or sheets, which also reflect the heat radiation incident in summer, may also be applied to the outer boundary surface of the insulating elements facing away from the interior to be insulated.
• This quiescent air layer is provided in known insulation systems characterized in that the reflective films are mounted on the boundary surface facing the interior to be insulated and / or facing away from the rafters. In the production of appropriate roof insulation systems, a particularly high workload is required.
• the present invention seeks to provide an insulation system that meets both the requirements of the winter and the requirements of the summer heat protection and can be installed while ensuring a safe and efficient construction process.
• this object is achieved by a development of the known roof insulation systems, which is characterized essentially in that the reflection layer at a boundary surface. the Dämmelements is attached.
• the invention is based on the surprisingly simple knowledge that it is not necessary to provide the required to ensure the effectiveness of the reflective film resting air layer, the reflective layer to move separately from the insulation elements, because the required static air layer is also provided by other measures ,
• By attaching the reflective layer on the insulating elements of the construction process is greatly simplified, because it is no longer necessary to obtain the desired insulation to move in several steps, first insulating elements and then reflective layers. Rather, this installation can be carried out using roof insulation systems according to the invention in only one step.
• the production of roof insulation systems according to the invention is particularly simple if the reflection layer has a reflective film laminated onto the insulating element.
• the reflection foil can be laminated with projection on the insulating element, wherein the supernatant for producing a connection with adjacent insulating elements and / or reflective films and / or other components of the roof construction can be used.
• This desired connection is particularly easy to implement if the supernatant is provided with an adhesive used for connection to an adjacent projection and / or insulating element and / or other components of the roof construction.
• the adhesive may, for example, be realized in the form of an adhesive strip on the supernatant.
• the overlap of adjacent supernatants can also be hermetically sealed.
• the to protect the summer heat protection on a facing away from the interior to be insulated boundary surface of Dämmelements reflection layer is expediently carried out diffusion-open, while on a the interior to be insulated facing boundary surface fixed reflection layer, which serves the winter heat protection, should be diffusion-inhibiting
• a reflective film offered by DuPont under the trade name "Tyvek Enercor” can be used.
• This reflective foil has a water vapor permeability according to EN ISO 12572 of 0.015 m (mean value). The water vapor permeability can vary between 0.005 and 0.035.
• a reflective film marketed by DuPont under the trade name "AirGuard” can be used as the diffusion-inhibiting reflective film.
• This reflective film has a water vapor permeability according to EN 1931 of 700 m (average). The minimum water vapor permeability is 200 m.
• Roof insulation systems according to the invention can be embodied as so-called rafter insulation systems.
• the quiescent air layer between the reflective layer and the interior facing boundary surface of the roof covering may be provided.
• an insulating element is secured with a mounted on the interior facing the boundary surface to be insulated reflection layer under the rafters of a roof truss, wherein the quiescent air layer between the reflective layer and a roof suspension can be realized.
• the attachment of the insulation elements by means of a base battens can be done, which can be bolted non-positively in the rafters, whereupon the usual covering, including battens, is mounted on the insulating elements.
• the insulating elements can be connected airtight and diffusion-inhibiting to adjacent and enclosing components with the aid of adhesive tapes.
• roof insulation systems can as well as insulation elements of known roof insulation systems polystyrene hard foam, mineral wool, rigid polyurethane foam and / or wood fiber insulation materials.
