Definitions

  • the invention relates to the insulation of ventilated roof spaces, in particular unused roof spaces, respectively in lofts or, as they are sometimes called, attics.
  • a heated building is insulated in order to reduce the heat losses. A significant part of the heat losses can take place through the ceiling and the roof.
  • Insulation of the unused roof space can be carried out by means of panels or rolls of insulation. However, these are sometimes difficult to handle in the access areas available, and they are problematic to lay in areas with low height. A loose insulation product in the form of flock is often preferred to them. The insulation product can be blown from underneath in the building, in a pulsed air duct towards the loft.
  • vents i.e. air inlets (vents) are left free of insulation.
  • the objective of the invention is to improve the situation.
  • the invention proposes a sloping roof space insulation installation according to claim 1, with a main portion comprising an upper face, a lower face which is supported on a roof space floor, and a tapered portion which is arranged at an end of the main portion, and is in contact with the said floor and with a lower roof surface in the vicinity of a lower edge of the roof.
  • the installation comprises a mat of loose insulation selected from amongst: stone wool, glass wool and cellulose, and a unit permeable to air, provided with regularly distributed openings, arranged on the surface of the tapered portion and retaining the loose insulation which forms part of the said tapered portion.
  • the insulation has a density of between 10 and 40 kg m -3 .
  • the unit permeable to air is a grid made of metal. The unit permeable to air ensures that the loose insulation is retained, thus preventing vents from being blocked, and contact with the roof, and reducing greatly the risk of displacement of the loose insulation.
  • the invention proposes also a sloping roof space insulation installation according to claim 2, with a main portion comprising an upper face, a lower face which is supported on a roof space floor, and a lateral face connecting the upper face and the lower face, comprising a mat of loose insulation selected from amongst: stone wool, glass wool and cellulose, and a unit permeable to air, provided with regularly distributed openings, arranged on the surface of the lateral face, retaining the loose insulation and pressed onto struts of the roof, the mat covering an underlying wall insulation.
  • the insulation has a density of between 10 and 40 kg m -3 .
  • the unit permeable to air is a grid made of metal.
  • the grid is made of metal, and preferably of galvanised steel.
  • the said unit permeable to air is non-combustible. In another embodiment, the said unit permeable to air is flame retardant.
  • the grid has a square, hexagonal or octagonal mesh with dimensions of 16 mm or less, preferably of 14 mm or less in terms of their largest dimension.
  • the said dimensions may be 2 mm or more, preferably 5 mm or more.
  • These dimensions are particularly suitable for stone wool and cellulose. Small dimensions are preferred for stone wool, such that the grid makes a significant contribution to reducing the speed of the wind. The retention of the loose insulation is satisfactory.
  • stone wool and cellulose are preferred in windy areas, for example coastal areas.
  • the insulation is made of stone wool and has a density of between 19 and 25 kg m -3 .
  • the insulation is in the form of flock with a diameter greater than 20 mm.
  • the unit permeable to air comprises a part in contact with the floor, a part in contact with the lower surface of the roof, and a part projecting towards the lower edge of the roof.
  • the unit permeable to air is adapted to the form of the roof timbers and the floor.
  • the unit permeable to air can pass below rafters, thus ensuring circulation of air between two adjacent rafters and between the roof covering and the loose insulation.
  • the roof covering means the part of the roof which forms the seal against water, in practice the tiles, slates or other covering elements, whereas the roof comprises the roof timbers and roof covering.
  • the unit permeable to air is secured on the floor and/or on the roof by means of nailing, stapling or by collars which can be clamped.
  • the nailing can be carried out with stapling nails.
  • Nailing and stapling are well-suited to floors and/or roof timbers which are made of wood.
  • Collars which can be clamped are well-suited to metal (mesh) or concrete roof timbers.
  • the unit permeable to air is in contact with a pantile, and is preferably secured to the pantile.
  • the unit permeable to air is secured to at least one strut of the roof timbers of the roof.
  • Loose insulation products are specified and described in European standard EN 14064-1 :2010 'Thermal insulation products for buildings.
  • stone wool is preferred because of its cohesion and its mechanical resistance in the case of strong wind. Stone wool is well-suited to windy conditions found on coasts, at altitude and in exposed situations.
  • the invention proposes also a method for insulation of a sloping roof space, according to claim 6, the roof space being provided with a floor, wherein a unit permeable to air provided with regularly distributed openings is fitted in contact with the said floor and with a lower roof surface in the vicinity of a lower edge of the roof, and loose insulation selected from amongst: stone wool, glass wool and cellulose is introduced, thus forming a mat, the assembly having a main portion comprising an upper face, a lower face supported on the floor, and a tapered portion or a lateral face arranged at an end of the main portion, the unit permeable to air forming together with the insulation the surface of the tapered portion, and retaining the insulation.
  • the work can be carried out rapidly, without laboriousness, and with a low risk of damage caused in the access areas.
  • floor means the lower surface of the roof space including the upper surface of the wall.
  • the floor is in general flat or slightly inclined. However there may be sloping portions.
  • the floor can be on one or a plurality of planes.
  • the unit permeable to air is fitted between two adjacent main beams and in contact with the said two main beams, and/or between two adjacent rafters and in contact with the said two rafters.
  • the retention is ensured at the bottom, the front or edge of the roof, and at the top.
  • the unit permeable to air is cut from a roll and formed by pressing it into the corner formed between the floor and the lower roof surface, in the direction of the said lower edge of the roof.
  • the unit permeable to air can be cut to the distance between two adjacent main beams and/or rafters.
  • the unit permeable to air can be cut by providing notches for the main beams and/or the rafters.
  • the unit permeable to air can be secured below the rafters and pass between each pair of main beams, whilst coming into contact with the floor.
  • the unit permeable to air is pressed into the said corner, thus forming a rounded projection.
  • the unit permeable to air can be pressed by means of a tool with a handle.
  • the unit permeable to air makes it possible to retain the loose insulation in line with wall insulation.
  • the loose insulation is introduced by blowing.
  • the loose insulation is put into form definitively by blowing.
  • the insulation is stone wool in accordance with European standard EN 14064-1:2010.
  • the stone wool used has a density of between 10 and 40 kg m -3 , preferably between 19 and 25 kg m -3 .
  • the stone wool can have an average flock size of between 20 and 30 mm.
  • the objective of the invention is to permit continuity of the insulation between a wall and a loft.
  • the loose insulation is delimited by a wooden panel arranged spaced from the wall. There is then a discontinuity between the wall, which is in general insulated, and the insulation of the roof space. This results in significant heat losses.
  • panels of this type are absent, then the loose insulation extends either until it falls onto the pantile, in the case of restoration of a house with conventional roof timbers, or until it comes well beyond the wall in the case of a modern house, thus blocking the vents which are generally arranged on the overhanging underside of the roof.
  • roof timbers generally comprise battens which support the roof, and are supported by rafters in the direction of the slope, the latter themselves being supported by horizontal purlins.
  • the lower purlin is supported on the wall and is known as the pantile.
  • the other purlins are supported on trusses which are spaced by several metres.
  • the truss has a triangular base structure with or without struts and/or braces.
  • Modern or industrial roof timbers generally comprise battens which support the roof covering, and are supported by prefabricated wooden, concrete or steel small girders.
  • the small girders are spaced by a few tens of centimetres, substantially by the distance between two aforementioned rafters.
  • the small girder has a triangular base structure.
  • Different types of bracing between the main parts which form the three sides of the small girder triangle exist in order to offset the load of the roof covering and limit the bearing distances, i.e. in the form of a stanchion, an "M", an "N”, a "W”, a fan, or a trimmed joist, etc.
  • the Applicant has realised that low areas, close to the edge of the roof, were often affected by a thermal bridge. It is desirable for such low zones to have insulation that substantially joins and covers the insulation of the walls in order to prevent a thermal bridge occurring, as this is a preferential area for heat losses.
  • the roof also requires ventilation in order to prevent condensation. Vents and air passages are vital for the sustainability of the roof.
  • a building comprises a wall 1 with a visible upper surface 1a, a loft floor 2, and roof timbers 3.
  • the upper surface 1a is horizontal.
  • the upper surface may form part of the floor.
  • the flooring 2 can comprise panels based on wood, for example of the OSB type, or on plaster.
  • the roof timbers 3 have small girders 4. Beyond the wall 1, the roof is overhanging, and is provided with a roof underlay 5.
  • the small girder 4 of the roof timbers 3 comprises a main beam 6 and one principal rafter 7, the other principal rafter not being visible in the figure.

  • the lower portion 11b is substantially horizontal.
  • the lower portion 1 1b is formed on the upper surface 1a of the wall 1.
  • the lower portion 11b is supported on the upper surface 1a of the wall 1.
  • the lower portion 11b can be attached to the upper surface 1a of the wall 1.
  • the lower portion 1 1b is free relative to the upper surface 1 a of the wall 1, the contact being ensured by the resilience of the grid 11 and the weight of the insulation.
