UdiSTEAM® 3.5 and 10 The ecological vapour retarder for diffusion permeable constructions. Triple bonded from two layers of Kraft paper and a layer of fibreglass. Possible sd-values EN 12572/A: 3.5 m (beige coloured), 10 m (green coloured) UdiSTEAM® 10 plus The innovative vapour retarder that adapts to the air moisture. The sd-Value changes according to a rise or fall in the relative humidity. Perfect for modernisations enabling residual moisture to dry out. Translucent, leaving the battens visible. Highly tearresistant PES-bonded fleece with an active copolymer layer. sd-value between 0.5–10 m according to EN 12572/A: UdiSTEAM® Tape elastoflex For the bonding of penetrations through our vapour retarders. Also suitable for aluminium sheeting, PP-fleeces and wood -based boards. Powerful, single-sided adhesive tape, tear-proof, highly elastic, free from solvents, halogen and heavy metals. Special polyacrylate binder on PE layer. Available in 60, 75, 100 and 50 mm widths, 25 m long. UdiSTEAM® Tex 155 A very robust, highly diffusion permeable product for use as a breather-, sarking- and cladding membrane. For all cladded and uncladded sloping roofs. Triple- layer, highly tear-resistant, UV- stabilised polypropylene fleece. Wind-, rainand insect proof application. Resistant to the open elements for 3 months. sdvalue 0.04 m µ-Value: 69 according to EN 12572/A. UdiSTEAM® Tape standard For the bonding of overlaps of our vapour retarders. Also suitable for aluminium sheeting, PP-fleeces and wood-based boards. In certain circumstances it may be necessary to use primers. Powerful, single-sided adhesive tape, tear-proof, free from solvents, halogen and heavy metals. Pure acrylate adhesive on special paper with a PE-covering. Available in 60, 75, 100 and 150 mm widths, 40 m long. Installation instructions The vapour retarder should be nailed or stapled to the battens or timbers on the warm (interior) side. A 10 cm overlap should be sealed airtight using UdiSTEAM Tape standard. Joints, openings and projections (e.g. ventilators) should be sealed airtight with UdiSTEAM® Tape elastoflex and difficult surfaces sealed using our UdiSTEAM® Butyl tapes. Sandy and dusty surfaces or UdiUNGER-DIFFUTHERM® wood-fibre insulation boards may need to be pre-treated with UdiSTEAM® Primer. UdiSTEAM® Tex 155 should be laid crosswise, beginning from the bottom of the construction and stapled or nailed at 10cm intervals. The green matt surface simplifies the installation by ensuring that the workers are not dazzled by reflected sunlight. In order to ensure an optimal level of insulation, the 10 cm overlaps and all joints, openings and projections (e.g. ventilators) should be sealed airtight with our external adhesive products. UdiSTEAM® Tex 155 should be protected from prolonged exposure to the elements and covered as soon as possible after laying.
