Definitions

• the invention relates to an adjustable window sill assembly comprising an window sill substructure and a window sill cover plate.
• the invention further relates to the use of said assembly for preparing a door step or parts thereof.
• the invention provides an adjustable window sill substructure comprising a wedge shaped first portion associated with the window reveal and a cuboid second support portion for the window frame, wherein the first portion and the second portion have a common basis, and wherein the adjustable window sill structure is an insulating structure comprising at least one segment made from rigid insulation material and at least one segment made from water resistant hard construction material.
• the window sill substructure of the invention has several advantages over the prior art equivalents.
• the window sill substructure of the invention can be adjusted in three ways: At first the substructure can be cut lengthwise at the wedge shaped portion in order to adapt it to different depth of the window reveal. Secondly, the substructure can be cut laterally in order to adapt it to the different length of the respective window sill. Thirdly, also the cuboid second support portion can be cut at its back side in order to be adapted to a window sill use or even a door step use. As such it has an enormous flexibility of application. Due to the presence of the light-weight insulation material, the overall weight of the window sill substructure is considerably reduced, so that it can be easily transported and installed. Due to the segment made from rigid insulation material the window sill substructure has good insulation property.
• the skilled person can refer to a broad spectrum of foamed insulation materials, which can be selected on the specific requirements on site.
• the substructure Due to its segment made from water resistant hard construction material, the substructure is protected in its uncovered parts from environmental influences, resulting in a durable window sill construction. Also here, the broad spectrum of water resistant hard construction materials allows selecting the optimal material with regard to costs, aesthetic appearance and durability.
• the adjustability for the window reveal depth is given by the wedge shaped first portion which can be cut lengthwise in order to accommodate for the required dimensions of the window sill. Hence, the prefabricated window sill substructures can be easily adjusted on the site of construction.
• the window sill substructure is based on known building materials, it can be easily produced in a cost efficient manner.
• the at least one segment which is made from rigid insulation material and the at least one segment which is made from water resistant hard construction material are connected by a permanent and form-locking connection.
• rigid insulation material is defined in the context of the invention as a single-piece solid insulation material. Thus it is clearly distinct from loose-fill insulation materials such as perlite or cellulose and from the single-piece but highly compressive insulation materials such as the rock or slag wool.
• the window sill substructure consists of one segment which is made from rigid insulation material and of one segment which is made from water resistant hard construction material.
• this permanent and form-locking connection is performed by using a bonding agent such as an adhesive.
• a bonding agent such as an adhesive
• the optimal bonding agent is selected based on the distinct building materials of the two segments. For example, when using polystyrol in combination with concrete, a poly vinyl acetate glue might be used.
• connection between the rigid insulation material and the hard construction material is given without any further bonding agent but using the adhesive properties of the rigid insulation material and/or the hard construction material.
• connection is performed directly by the production process of the substructure.
• the flowable concrete as hard construction material can be poured onto the porous insulation material and will also penetrate into the porous insulation material.

• the adjustable window sill substructure is characterized in that at least the common basis of the first and the second portion and the backside of the second portion are made of a rigid insulation material, and furthermore at least the front side of the second portion is made of a water resistant hard construction material. Due to the fact that the common basis of the first and second portion is made from rigid insulation material, this insulating segment constitutes a continuous insulation strip that insulates the interior of the house from the exterior eliminating any thermal bridge effect.
• the cuboid second support portion for the window frame is build by the insulating foam (located at the back side of the substructure) and the hard construction material (located at the front side of the cuboid support function)
• the adjustable window sill substructure has one or more lengthwise grooves within the common basis of the first and second portion.
• These grooves can fulfill two functions: At first they can retain any bonding agent which is used for joining the substructure to the underground, being preferably the bottom side of the window reveal. Secondly, the grooves can serve as orientation (or even as a predetermined breaking point) when cutting the substructure to the desired depth.
• the water resistant hard construction material covers the front side and possesses in its upper part a protruding nose or extension, which preferably is located in the upper front edge. Said nose or extension towers above the window sill cover plate and thereby prevents water penetrating between the cover plate and the substructure. Furthermore, it protects the window frame against water on the cover plate being blown by the wind towards the window.
• the first portion and the second portion of the adjustable window sill substructure are made of a rigid insulation material with only a C-shaped structure of the water resistant hard construction material covering the front side and the anterior upper side of the first portion and the interconnecting corner of the first and the second portion.
• This specific embodiment is useful for a combination with a window sill cover plate lying on the substructure and which is then reaching up to said C-shaped structure.
• the upper part of the C-shaped structure is given by the above described nose or extension towering over the cover plate.
• the C-shaped structure comprises a backside which at least in its lower part is inclined rearwards. This reduces the formation of entrapped air when casting the C-shaped structure with a flowable construction material such as concrete.
• the C-shaped structure comprises both, the feet- like enlargement and the backside being inclined rearwards.
• the hard construction material is confined to only those parts of the substructure that are oriented outwardly. Thereby the insulation properties are maximized, and the more costly hard construction material minimized with out loosing durability and weather-resistance.
• the window sill substructure can be combined with various window sill cover plates of the prior art. This plate can be made from e.g. plastics, wood, stone or concrete.
