1 Kronospan OSB 3 Superfinish ECO Superfinish is the most progressive OSB type that is currently available. Superfinish is developed and manufactured entirely in compliance with the current demand of ecological living focused on organic materials. Selecting suitable wood and binder, OSB Superfinish meets high standards of not only environmental buildings. Strands are bound with a formaldehyde-free binder. Formaldehyde emissions are limited to the natural content of formaldehyde in solid wood ( 0.03 ppm ). EN type OSB 3; EN : class D-s2, d0; EN A1: EN EN ISO High durability and resistance - High load-bearing capacity - High performance material - High stability - Billboard production - Exhibitions (displays, stands, kiosks) - Flooring base - Framework for upholstered furniture - Internal load-bearing cladding of walls and ceilings, partitions - Warehouse management (racks, fences, etc.)

2 OSB 4 Superfinish is the most progressive OSB type that is currently available. OSB Superfinish is developed and manufactured entirely in compliance with the current demand of ecological living. Selecting suitable wood and binder, OSB Superfinish ECO meets high requirements of not only environmental buildings. Strands are bound with a formaldehyde-free binder. Formaldehyde emissions are limited to the natural content of formaldehyde in solid wood ( 0.03 ppm ). EN type OSB 4; EN : class D-s2, d0; EN A1: EN EN ISO Excellent price / performance ratio - Inceased resistance to humid conditions - Billboard production - Cladding - Exhibitions (displays, stands, kiosks) - Shutters - Warehouse management (racks, fences, etc.) OSB AIRSTOP SB Airstop core is OSB Superfinish described by EN 300 standard as OSB/3 type (load-bearing board for use in humid conditions). A special foil of cellulose is applied on this board via adhesive laminating process. The foil reduces the differences in the boards heterogeneity therefore giving the precise defined values of airtightness and vapor resistance. In the diffusion-open structure this allows for installation of reinforced sheathing, airtight barrier and vapor check at once. OSB focuses closely on the needs of current construction trends of modern low-energy and, in particular, passive wooden houses which have higher requirements for airtightness of external building envelope.

3 EN type OSB 3; EN : class D-s1, d0; EN 13986:2004+A1:2015 E1 (EN 120) No added Formaldehyde - Environmentally friendly and Recyclable - Simple processing with conventional woodworking tools OSB Firestop The base plate is OSB Superfinish board, to EN 300 standard, labeled as OSB 3 and equipped with patented fire-resistant Pyrotite finish on one or both sides. As opposed to conventional wood-based boards, the OSB Firestop has a better classification in the evaluation of reaction to fire. According to European classification (EN ), it meets class B-s1, d0. The Pyrotite finish coating consists of fireproof materials that are based on magnesium oxide, reinforced with a fiberglass mesh. This finish provides a very strong connection with OSB board in addition to the high resistance to burning. Furthermore, it increases the board bending and shear strength in all thickness categories. OSB Firestop boards provide the strength and safety of building structures. During a fire they ensure integrity for a much longer duration than, for example; drywall. Additionally OSB Firestop boards are lighter and stronger than drywall. With the same thickness they achieve comparable fire resistance qualities to cladding systems based on a combination of OSB boards and drywall. Using OSB Firestop boards saves assembly time and is more cost-effective. Pyrotite technology for OSB boards has more than fifteen years of verified functionality. In contrast to conventional fire protective coatings designed for wood-based products, Pyrotite does not lose its protective qualities over time.

4 E1 (EN 120) No added Formaldehyde - Easy fixation using conventional fasteners (screws, nails, staples) - Easy processing - Flame retardant, ability not to contribute to fire spread and not to form burning droplets - Construction of roofs or shelters - In public spaces which are subject to stringent fire risk assessment OSB REFLEX OSB Reflex core is OSB Superfinish OSB/3 type as load-bearing for use in humid conditions. Special reflective aluminum foil with cellulose base is applied on this board via adhesive laminating process. Highly reflective aluminum foil excels by its low emissivity coating which effectively reduces transmission of radiant heat. This helps reduce heat loss in winter and also excessive solar gains in summer. They can be used for example in roof structures or generally in worse thermal insulated buildings. Formwork boards are able to reduce radiant heat transfer of up to 97%, thereby reducing the temperature on a hot summer day under the roof by 5 to 15 C. They can also be well used in combination with an air gap where OSB Reflex replacing up to 50 mm of conventional thermal insulation.
