Construction Facings

- insulation facings Insulation properties and energy efficiency can be considerably enhanced with facings. Walki’s versatile product range of insulation facings offers facings suitable for mineral wool, polyurethane and other building boards like plasterboards. Our facings provide excellent gas tightness and low emission properties. High performance material combinations improve breathability and mechanical strength of the material, in addition to reducing fire load. Construction Foam Facings
Polyurethane insulation panels require facings that offer tightness, heat resistance and mechanical strength. Facings must also endure moisture and different types of chemicals during use. Due to the higher focus on the environmental impact of the home and living spaces, demands on the manufactures of facing materials have increased. Different foaming methods call for compatible facings that maximise the insulation properties of polyurethane.
Walki®Foam Seven DT FR Walki®Foam Seven DT Fire Retardant has all the essential features for producing a premium insulation board. This product is designed for applications requiring a flame retardant facing while it has excellent thermal insulation properties and the diffusion tight gas barrier it creates maintains low lambda values in the long term.
Walki®Foam Seven DT Walki®Foam Seven DT has all the essential features for producing insulation board. It has excellent thermal insulation properties and the diffusion tight gas barrier it creates maintains low lambda values in the long term. When rigid PU foam insulations are used for demanding purposes - such as cavity walls, pitched roofs and flooring applications - an advanced facing is needed. Walki®Foam Five DT Walki®Foam Five DT is typically used for roof, wall and flooring applications. It has all the essential features for producing a premium insulation board. The excellent thermal insulation properties together with the diffusion tight gas barrier, in a long term, it maintains low lambda values.
Rigid PU foam insulations in demanding conditions call for more advanced facing materials. Walki®Foam Gypsym DT Walki®Foam Gypsym DT is a sophisticated facing designed for indoor insulation boards. As the name suggests, the product can also be attached to gypsum and particle boards. It has excellent thermal insulation properties and the diffusion tight gas barrier it creates maintains low lambda values in the long term. Construction Wool Facings Mineral wool insulators, such as mats, slabs and pipe sections, are coated with facings offering a variety of properties and strengths.
Walki's comprehensive product offering ranges from a simple polymer coated paper to complex multi layer solutions. We provide our customers with high-quality materials and solid competence in facing applications together with our versatile production lines.
Walki®Wool Alnet
Walki®Wool Alnet is a heat sealable aluminium facing strengthened with a glass fibre scrim designed for mineral wool insulation facings. Commonly used as facing for lamella mats, pipe sections and slabs.
 Walki®Wool Alnet G Walki®Wool Alnet G is gluable aluminium facing strengthened with a glass fibre scrim. Mineral wool products may include boards, mats or different pipe insulations. Facing protects them from moisture and improves their fire classification. Facing also facilitates the treatment and installation of insulation products which is an important benefit. The PCS value of the facing itself may be limited to 2 MJ/kg, corresponding the Euroclass A1 fire classification. Walki®Wool Alnet Sono Walki®Wool Alnet Sono is a perforated, heat sealable aluminium facing for mineral wool, strengthened with a glass fibre scrim.
Good sound and noise reduction propertieseach can be achieved due to the perforation of over 30,000 punctures in a square meter. Walki®Wool Alnet Sono finished insulations are often used in air ducts and ceiling panels. The facing can be lacquered and printed. Construction Gypsum Facings
Walki’s plasterboard facings for the construction board industry are weather resistant and mould retarding. They offer breathable and moisture blocking protection by letting humidity out while preventing water from getting in. In addition, the plasterboard facings help keeping the desired temperature level in the building by preventing heat from escaping or entering, thus providing for energy efficiency and comfortable and sustainable living.
Walki®Wall Walki®Wall is a superior facing for wind barrier plasterboards. Weather resistant and mould retardant, it offers breathable protection by letting humidity out while preventing water from getting in. Treated on one side Walki®Wall gives good adhesion for the gypsum slurry, the product achieves its final water repellency and breathability characteristics during the plasterboard manufacturing process.
