The disclosure relates to façade system for a building, in particular an External Thermal Insulation Composite System (ETICS), comprising a thermal and/or acoustic insulation, consisting of at least one insulation element being a bonded mineral fibre product made of mineral fibres, preferably stone wool fibres, and a cured aqueous binder composition, whereby the insulation element is fixed to an outer surface of the building by mechanical fastening elements and/or an adhesive, covered with a rendering, and whereby the aqueous binder composition prior to curing comprises a component (i) in form of one or more oxidized lignins, a component (ii) in form of one or more cross-linkers, a component (iii) in form of one or more plasticizers, and whereby the insulation element has a bulk density between 70 kg/m.sup.3 and 150 kg/m.sup.3.

A liftable roof for recreational vehicles includes a lower frame stably connectable to the upper surface of the recreational vehicle, handling structure connected to the lower frame, and an upper lid operatively connected to the handling structure. The handling structure is configured for moving the lid with respect to the frame between a first lowered position and a second raised position. The upper lid includes a single panel with a first resistant upper layer and a second layer made of thermo-insulating material fixed on a lower surface of the first upper layer.

An insulation product includes a first layer of a fibrous insulating material, a second layer of a facing material attached to a first surface of the first layer, and a third layer of a slip sheet material and/or a lubricant attached to a second surface of the first layer. The first surface and the second surface are on opposite sides of the first layer and are parallel to one another. For certain applications, the insulation product may include a layer of a slip sheet material and/or lubricant attached to the first surface of the first layer instead of the second layer of a facing material.
