A rigid foam or composition allowing a rigid foam to be obtained made from polyurethane and/or polyisocyanurate. The rigid foam or composition includes polyols selected from polyester polyols and polyether polyols; the polyols include: 5 to 50% of a polyester polyol A by weight relative to the total weight of the polyols; and a polyol B selected from polyester polyols B and polyether polyols B. The polyester polyol A is of general formula Rx-Ry-Z-Ry'-Rx&#x2032; in which Z is a C3 to C8 alcohol sugar chosen from glycerol, sorbitol, erythritol, xylitol, araditol, ribitol, dulcitol, mannitol and volemitol. Ry and Ry&#x2032; are diesters of formula &#x2014;OOC&#x2014;Cn-COO&#x2014; in which n is between 2 and 34, and Rx and Rx&#x2032; are identical or different C2 to C12 monoalcohols.

Rigid foam with improved insulating power

One subject of the present invention is a roofing device () comprising an area support () made up of panels of wood particles on which a vapor barrier first layer (), an insulating second layer () and a third layer () that is impermeable to liquid water are laid. Said device () is one wherein the second layer () is a composite layer formed by the superposition of two distinct homogeneous elementary layers (and'), namely a lower elementary layer () of wood fiber and an upper elementary layer (&#x2032;) made up of a material that is at least partially bio-sourced, that has hygroscopic, antifungal and thermal-insulation properties and that has a low resistance to the diffusion of water vapor.

Thermally insulated roofing device

Disclosed is a binder of vegetable origin based on modified tall-oil pitch, modified vegetable resin and optionally oil. Also disclosed are leakproofing membrane compositions, soundproofing membrane compositions, liquid sealing system compositions, asphalt mix coating compositions, asphalt coating compositions, primer compositions, varnish compositions, mastic compositions, adhesive compositions or binder emulsion compositions which comprise said binder. In addition, a method is disclosed for reducing the amount of bitumen of petroleum origin in said compositions.

Binder of vegetable origin, compositions comprising same and method for reducing the amount of petroleum-based bitumen

Disclosed is a binder of vegetable origin based on oil, modified vegetable resin and optionally a heat stabilizer. Also disclosed are leakproofing membrane compositions, soundproofing membrane compositions, liquid sealing system compositions, asphalt mix coating compositions, asphalt coating compositions, primer compositions, varnish compositions, mastic compositions, adhesive compositions or binder emulsion compositions which comprise said binder. In addition, a method is disclosed for reducing the amount of bitumen of petroleum origin in said compositions.

The invention concerns a method () for recovering and/or recycling a bituminous product by means of pulsed power, the bituminous product comprising bitumen and elements to be separated, involving the following steps:

Method for recovering and/or recycling a bituminous product

Disclosed are granules comprising an elastomeric polyurethane and bitumen, processes for preparing the granules in an extruder and to their use for preparing a bituminous binder, which may especially be used for producing prefabricated sealing membranes by depositing said bituminous binder onto a fibrous support.

Granules comprising bitumen and a thermoplastic polyurethane elastomer, method for its preparation and its uses

A device for supporting and attaching panels to a roof including an added sealing covering on the surface thereof includes brackets for tiltedly supporting and bearing the panels, including a bottom bearing portion and at least one top portion for supporting the panels, the brackets having a triangular structure and consisting of a hollow body. The device is characterized in that the bottom portion () of the brackets () is provided, on the underside thereof, with at least one added plate () secured to the console (), wherein the plate(s) () consist of a material or contain a material that is compatible with and/or similar to the layer or the surface coating of the roof covering (), and are bonded to the layer or the covering by an adhesive bond, and in that the top portion (') provides bearing surfaces for the edges of the panels or profile members for mounting such panels.

Device for supporting and attaching panels or the like, and roof system comprising such a device

A device for fixing elements in the form of plates to a roof cover for a building, at a distance therefrom, the cover including, on the surface, a coating or a sealing layer attached to the essentially continuous support forming the roof, the device including blocks that can be height-adjustable or not, for supporting and holding the plate-shaped elements, each block having a base with a lower smaller plate to be applied to the surface of the cover and secured thereto, and a head or upper part for directly or indirectly supporting at least one plate-shaped element, the bottom face of the smaller plate () of the base () of each block () being provided with a part () of the plate, forming a protector, which is mechanically fixed to the smaller plate ().
