What is the size of one roll of LATIVA 220 under-roof membrane?
The product listing and image of LATIVA 220 indicate a size of 50 x 1.5 m. This equals 75 m² of nominal material before overlaps, cutting, and detailing. The usable roofing area should not be assumed to be 75 m² without the installation scheme. For ordering, each slope is calculated and the necessary amount for joints, gutters, ridges, and openings is added.
What does the number 220 mean in the LATIVA 220 membrane?
In the product image, 220 is shown as 220 g/m², meaning the surface mass of the material, not thickness in millimeters or roll area. The size is separately indicated as 50 x 1.5 m. Upon receipt of the goods, these data should be checked against the label and technical declaration of the specific batch.
Where in the roofing system is LATIVA 220 used?
The model is cataloged as an under-roof membrane, therefore it is a product for the layer beneath the final roofing cover, not an internal vapor barrier foil. The public listing does not contain a complete technical scheme for the exact position relative to insulation and wooden decking. Before installation, the supplier must provide the applicable detail for the specific roof and batch.
Is LATIVA 220 the same as EUROBARRIER Q160 or Plus?
There is no verified document showing that this model is a renamed EUROBARRIER Q160, Plus, or another product. The different name and surface mass do not prove identical structure, strength, Sd value, or installation restrictions. Therefore, indicators and instructions from JUTA should not be automatically transferred; only the technical declaration for the exact private product is used.
Which side of LATIVA 220 should face the roofing cover?
The public product listing does not provide a verified written instruction for the orientation of this model. The direction should not be determined solely by the promotional photo. Follow the printed marking on the roll and the technical instruction of the delivered batch. If the document is not available, installation must be stopped until confirmation, as the wrong side may compromise the designed roofing detail.
What must be confirmed before ordering LATIVA 220?
Besides the size 50 x 1.5 m and mass 220 g/m², waterproofing, Sd value, strength in both directions, UV exposure, temperature range, allowable substrate, orientation, and overlaps must be confirmed. These indicators are not published in the product listing. Without a technical declaration, no specific minimum slope, temporary covering, or compatibility with all roofing systems should be promised.
