For good reason one can assume that the rocks that our grandparents gave over their huts when they abandoned the existence of cave people. Torvtak was our most common roof covering for a period of time. On the same basis, one can ask if there is any need to preserve this 6,000 year old roofing tradition.
Surprisingly, the answer is yes. The reasons are not only aesthetic and cultural. Several straw news, even fireproof roofs, are now being manufactured in Germany and Denmark and more countries are in progress. A traditional thatched roof has both pros and cons. The benefits include, among other things, the three-fold good insulation ability - against cold, heat and sound.
The advantage that is likely to be thought of is, however, the formability of the materials. Both whey and straw have a soft compassion that is far superior to all other roofing materials and therefore allows such charming details as, for example, so-called eyebrows over doors and skylights. But unfortunately there are also a lot of negative sides with thatched roof. The beam roof is, for example, flammable. In itself, the ceiling can be made fireproof, but it is often both complicated and expensive.
Other possibilities that have been tried to make the roof more fire resistant are to cover the straw bed with materials like sand, cement and fiberglass mats. So far, however, the trials have resulted in excessive aesthetic losses. Different types of impregnations have also been tested in different parts of the world where straw roofs are common, but yet no method has been shown to last more than a year.
The first rows were of a material that was close to hand, namely sharp, sausage and the like. But also grass, lion and seaweed have been used. Later, the rye and wheat fields also provided a natural covering material. Today, wheezing predominates, mostly because shrub has longer shelf life than straw. The average size of the roof is about 45 years, provided that the nock is "reversed" about every five years.
The roof tiles are hardly anything gained in the usual construction market. In most cases, the roof rack is self-sufficient. But especially in the case of marsh, a lot of imports from Poland, Czechoslovakia, Hungary and Austria are imported. The heaviest cost item in the case of thatched roof is the setting itself. Therefore, most of the roofs are also placed on culture-historically interesting buildings.
Both saltwater and freshwater ponds can be used for roofing. The only real difference between the varieties is that the freshwater water is usually getting higher and thicker. Vass can only be harvested with amphibian ornaments or beaten, which is the main explanation for the high price.
The harvest time is normal in November-February. The water should be 140-160 cm high. Especially at sea wax, the straw should be as thin as possible, as the vessels then get greater strength and longer life.
Thanks to moisture insulating plastics and the ability to buy prefabricated lawns rolled out on a peat bed, the placement of peat roofs has become an interesting thing the self-esteem.
Decisions are closely related to peat roofs. The moisture insulation is the same, but instead of peat, thin tree trunks have been worn in the middle and then laid down with the flatside downwards.
When choosing a roof covering, always take into account the aesthetic character of the material, the roof railing, the substrate, material and laying costs. Always consult the building board.
Cuttings are laid out by the so-called stickspoon like planed, split or sawed wood. The chip is laid about 15 cm around on a board. Sticks are still manufactured to a limited extent. The country museums usually provide tips on where the material can be bought. The stickspoon is generally untreated, but can be ironed with wood to prevent the sun from licking the softer substances. Both chips and rooftops were hit harder by sun than rain and storm winds.
