25-431: Päijät-Häme boasts a landscape shaped by two key features. Finland's second-largest, Lake Päijänne , dominates the region, offering a vast freshwater expanse and a vital transportation route. The Häme Ridge , a glacial remnant, adds a touch of elevation and scenic variation. Beyond these, Päijät-Häme features extensive coniferous forests . Rolling hills provide scenic views, while numerous smaller lakes and rivers create

50-470: A Pre-Finno-Ugric substrate language. Päijänne is a famous boating , canoeing and sailing attraction. The 119 kilometres (74 mi) long lake is connected by canals to Lake Keitele , Lake Vesijärvi and to Lake Ruotsalainen. Length of the open waterway for ships is 380 kilometres (240 mi). Construction of canals connecting Päijänne to the Baltic Sea has been discussed for decades. Nevertheless,

75-488: A Tourism and Environment award presented by the European Union Commission in 1995. Päijänne National Park ( Finnish : Päijänteen kansallispuisto ) is a national park in the southern parts of Lake Päijänne. It consists of 50 unbuilt islands and parts of inhabited islands. The national park has been established in 1993 and has an area of 14 square kilometres (5.4 sq mi). Leivonmäki National Park

100-453: A crucial role in rural life until World War I, with some later being divided into new farms. Today, Päijät-Häme's settlement can be divided into three zones: the sparsely populated eastern area with smaller farms and estates, the more densely populated central region with a strong presence of independent farms, and the sparsely populated north with vast forests. As transportation networks evolved, settlement patterns shifted, with Lahti emerging as

125-692: A great island, nowadays it means a great forest area. The largest city on the shores of Päijänne is Jyväskylä in the North. The city of Lahti is connected to Päijänne through Lake Vesijärvi and Vääksy canal. An underground aqueduct , Päijänne Water Tunnel , connects the lake to Vantaa , providing the Greater Helsinki area with water. The deepest point in any lake in Finland is in Päijänne (95.3 m or 313 ft). The name of Lake Päijänne comes possibly from

150-513: A magnet placed over a conveyor belt on which the chips move forward. In the case of, for example, MDF (medium density fiberboard) and not particle board, chips are then steamed to soften them for defibration . Small amount of paraffin wax is added to the steamed chips and they are transformed into fluffy fibers in a defibrator and soon afterwards sprayed with adhesives such as urea-formaldehyde (UF) or Phenol formaldehyde resin (PF). Wax prevents fibers from clumping together during storage. Chips in

175-406: A network of waterways . Päijät-Häme's landscape reflects the dramatic retreat of glaciers . The last Ice Age carved the land, leaving ridges ( Salpausselkä ) and large lakes ( Finnish Lakeland ). As the ice melted, the Baltic Sea went through various stages, dramatically changing shorelines. Land rose, creating islands and eventually dry land. Human settlement followed the receding water, with

200-468: A skin, foil, or fabric such as cloth, suede, leather, or polyvinyl chloride . RSI Direct , a bi-weekly e-newsletter covering the roofing, siding and insulation industries, promotes the use of fiberboard as a coverboard in roof systems: More than two billion square feet of this product have been installed in the U.S. roofing market. Currently, there is no commercially available method to recycle fibreboard, and landfilling and burning for energy are

225-492: Is between the cities of Lahti and Jyväskylä . There are 16,000 cottages on the shores of Päijänne. Most of the cottages are private owned and have a separate sauna cottage. In addition to cottage tourism Päijänne attracts fishing, sailing, canoeing, rowing, paddling, trekking, ice-skating, snow mobile and nature tourists. The National Parks of Päijänne and Leivonmäki alone has tens of thousands of visitors every year. The Clear and Drinkable Lake Päijänne South Association won

250-573: Is situated few kilometres North East from the Northern part of Lake Päijänne. It is one of the youngest national parks in Finland. From North to South Fiberboard Fiberboard ( American English ) or fibreboard ( British English ) is a type of engineered wood product that is made out of wood fibers . Types of fiberboard (in order of increasing density) include particle board or low-density fiberboard (LDF), medium-density fiberboard (MDF), and hardboard or high-density fiberboard (HDF). It

275-411: Is sometimes used as a synonym for particle board, but particle board usually refers to low-density fiberboard. Plywood is not a type of fiberboard, as it is made of thin sheets of wood, not wood fibers or particles. Fiberboard, particularly medium-density fiberboard, is heavily used in the furniture industry. For pieces that will be visible, a veneer of wood is often glued onto fiberboard to give it

300-574: Is the second largest lake in Finland (1,080 km (266,874 acres)). The lake drains into the Gulf of Finland via the Kymi River . The major islands are from north to south Vuoritsalo , Muuratsalo , Onkisalo , Judinsalo , Edessalo , Taivassalo , Haukkasalo , Vehkasalo , Mustassalo , Virmailansaari and Salonsaari . The largest island is Virmailansaari. The word saari means an island. Salo once meant

325-656: The Battle Axe culture around 3200 BC brought new tools and pottery styles. During the Bronze Age (1900 BC), cremation burials and large stone cairns became common. In the Iron Age , settlements shifted to better farming areas near waterways. Viking raids and unrest marked the later Iron Age. Christianity arrived during the Crusades (1050-1300 AD). By the Middle Ages , villages dotted

350-582: The Porvoo River valley being the oldest cultural landscape. Today, Päijät-Häme boasts a unique blend of lakes, ridges, and reminders of its glacial past. After glaciers retreated 11,000 years ago, the first settlers arrived in Päijät-Häme. Birch dominated the initially barren landscape. As the climate warmed, people lived near ancient lakes and bays. By 5100 BC, the Comb Ceramic culture thrived. The arrival of

375-505: The 19th century revolutionized transportation, and later road networks further influenced development. Heinola , for example, benefitted from its location near the Kymijoki River, which facilitated industrial growth once railways arrived. This pattern likely mirrored itself across Päijät-Häme during the 1800s and 1900s. Heinola, founded in 1776, became the region's first city in 1839. Industrial areas grew around its center, particularly on

400-537: The appearance of conventional wood. In the packaging industry, the term "fiberboard" is often used to describe a tough kraft -based paperboard or corrugated fiberboard for boxes. "Fiberboard" is also an intermediate product, an output of a pulp mill used as input for a paper mill . Fiberboard manufacture begins with wood chipping: fresh or recycled wood material is cut and sorted to small pieces of similar size. Chips are washed to remove things such as dirt and sand. Metal scraps such as nails can be removed with

425-527: The binding agent used in this type of fiberboard is an all-natural product, consisting of vegetable starch containing no added formaldehydes. Fiberboard, classified by ASTM C208, Standard Specification for Cellulosic Fiber Insulating Board, has many benefits and is used in residential and commercial construction. Applications include: Fiberboard is also used in the automotive industry to create free-form shapes such as dashboards, rear parcel shelves, and inner door shells. These pieces are usually covered with

450-541: The case of particle board are also sprayed with a suitable adhesive before the next steps. Fibers or chips are arranged into a uniform "mat" on a conveyor belt. This mat is pre-compressed and then hot-pressed. Hot-pressing activates the adhesive and glues the fibers or chips together. Board is then cooled, trimmed, sanded and maybe veneered or laminated . UF resins are dominantly used in the MDF industry because of their low cost and fast curing characteristics. However, pressures on

475-423: The dominant population center. Villages in Päijät-Häme have a long history intertwined with the landscape. Most likely arose around the 16th century, strategically placed near ridges and waterways for easy access to water and fertile land . Water remained the primary mode of transportation for centuries, with some villages even shifting their centers to be closer to navigable routes. The arrival of railways in

500-797: The east and south sides. Lahti's story is tied to railways and lakeside industry. It gained market town rights in 1878 and city status in 1905. Factories like sawmills , a pulp mill , and match factories fueled Lahti's expansion. Village churches (kirkonkylät) also saw growth from the 1860s onward, spurred by relaxed land ownership laws. However, rapid expansion in some villages obscured their older features. Lahti housed sawmills, pulp mills, glass factories, and textile producers. Heinola developed sawmills, plywood , and fiberboard factories alongside metalworking. Notably, Hämeenkoski had Finland's first flax cleaning plant built in 1888. Worker housing districts accompanied industrial growth. The passage mentions both early examples and later, larger developments from

525-617: The fiber mat temperatures, molecular weight distribution of PF resins and pressing parameters. As a result, the press times for PF-bonded fiberboard can be made comparable to those for UF-bonded fiberboard. Also, the resin content required for PF-bonded fiberboard is less than 5% to achieve a good board quickly. This is considerably lower than that required for UF-bonded fiberboard. Certain types of fiberboard can be considered "green" building products. Consisting of bio-based, secondary raw materials (wood chip or sugarcane fibers) recovered from within 100 miles (160 km) of manufacturing facilities,

550-506: The plan is still to be materialized. Until the 1940s Lake Päijänne was a major transportation channel in the Central Finland . Numerous ships transported passengers and freight between the villages and cities on the shores of Päijänne. Nowadays, passenger transportation is rather a tourist attraction on the lakelands than the fastest way connecting the cities and villages. One of the most popular passenger transportation routes in summertime

575-696: The post-war period and the 1960s and 70s. Blazon: Azure, a mermaid and in dexter chief a cuckoo close Or. In laymen's terms: The coat of arms sports a depiction of the ancient water goddess Vellamo as a mermaid, with a cuckoo. The region of Päijät-Häme consists of 10 municipalities , two of which have city status (marked in bold).

600-415: The shores of waterways and lakes. The 16th century saw a solidification of village life, with the most prominent settlements around Hollola , Lahti , and Nastola . The 1800s brought a boom in agriculture, with cultivated land tripling and industries like flax farming and cattle raising flourishing. Forests were mostly owned by farms, and improved transportation facilitated timber sales. Manor houses played

625-433: The use of UF resins are mounting steadily due to potential problems associated with formaldehyde emission. On the other hand, PF resins are more durable and do not emit formaldehyde after cure. The industry has traditionally shied away from using PF resins due primarily to their higher cost and much slower curing rate than UF resins. However, the press times for PF-bonded fiberboard can be substantially reduced by manipulating
