Ultipro Undertak og vindsperre_EN_JUNI 2020INSTALLATION INSTRUCTIONS ULTIPRO UNDERLAY Combined wind barrier and underlay Ultipro underlay Diffusion-open underlay supplied by Optimera AS. The product works as a combined wind barrier and underlay. Ultipro underlay has a width of 1,5 m and a length of 50 m. A roll covers a gross 75 m2 and a net area of 70m2. Longitudinal joints are attached by using integrated adhesive. NB: Roofing must always be completed as soon as possible after the underlay has been installed! Avoid spilling paint and solvents on the product. The roof construction must not be insulated before the sealing properties of the underlay have been checked and the roofing has been completed. Ensure that there is a tight seal between the counterbattens and underlay. We therefore recommend the use of butyl sealing tape between the underlay and counterbattens. Transport and storage Store the rolls protected from sunlight. Prerequisites for use Read through the installation instructions before using this product. Ultipro underlay can be used as a combined underlay and wind barrier in insulated, angled wooden roofs with battened roofing and exterior gutters. Combined underlay and wind barrier is particularly suitable for roofs that are continuously insulated from the eaves to the roof ridge, and for partially heated loft spaces. The roof slope must be at least 15°. Ultipro underlay is directly laid onto roof trusses, rafters and similar with a maximum separation of c/c 1200 mm. Ultipro can also be used on roofs with roof boards (rough panel, not OSB boards) where the loft space must be fully insulated from the inside. In such case, make sure that any old diffusion-sealed roofing is removed. The product is a secondary seal in the roof construction and should only be used under roofs with good watertightness against hard rain and driving snow, particularly in areas exposed to bad weather. Ultipro underlay is among the market’s most diffusion-open underlay product available in rolls. If the building is extremely damp, condensation may however arise on the inside of the underlay. If so, a dehumidifier must be used to achieve more rapid stabilization. Check the requirements for underlay from the choosen primary roofing manufacturer! Whenever a simplified solution is constructed with only one layer of ventilation and the underlay also functions as a wind barrier, it is extremely important that all components are constructed precisely. All joints must be sealed. The integrated adhesive in Ultipro will help you with this. Ultipro Underlay can be installed directly onto pine or spruce decks of older, insulated roofs intended for renovation. In such cases, butyl tape should be used to ensure that joints are sufficiently sealed, which is essential for the product to work properly.

It is equally important to create good ventilation. For roof surfaces that are less than approximately 7 meter from purlin to roof ridge, it will normally be sufficientwith counterbatten dimensions as shown in Table 1. Note that the width of the counterbattens does not exceed >48 mm. Before you begin installation Please read all sections of the installation instructions thoroughly before starting to work. Any latitudinal joints must be clamped as shown in Fig.2 Ultipro underlay shall form an airtight and watertight layer. The roof is ventilated between the roofing and the underlay. See Fig. 2–16 for details and method. If you follow these instructions closely, you will achieve a good and effective result.
