The roof is the most important element in the construction, when the building is already fully covered by a roof, you can not worry about the structure. But to perform the finishing touches when constructing a roof to keep in mind several important points. The first is the device insulation - is one of the most important points when constructing a roof of corrugated board . The second point is a vapor barrier. This item should be given due attention, as this vapor barrier is needed for insulation rays. When severe winter temperature difference on the street and in the house quite palpable, and then the building may appear damp, condensation and streaks on the ceiling. It is clear that this will lead to rapid destruction of the structure. Between the roofing and insulation should be a layer of vapor barrier. As a more suitable material can be selected mineral wool. The form they may be either rectangular or wedge-shaped, which makes it very easy for them to place on the roof, and the plates are easily dock with each other.
Now there are many opportunities and ways for fixing insulation boards. This, as has long been a proven method of fixation with nails and screws, and using modern tools, such as a vraspor or special glue. There is a version of the attachment with straps that are nailed to the inner sides of rafter feet.
If you have no attic and built a flat roof insulation layer can be located both outside and inside.
If you prefer to place a layer of insulation from the outside, you should use rigid plates, which are stacked on top of the boards of the bearing structure, forming a solid base for paving slabs. And in this case supporting structure must be ultra-strong, or your roof just start leaking.
Alternative insulation roof of corrugated sheets inside the building is more acceptable. This can be used polystyrene plates 25 mm thick. These plates are glued to the bars, fastened to the ceiling along the walls.
If you're still you will be building an attic, you should insulate him from the roof surface. The best in rigid or semirigid plate. The optimum size of boards should be: a width of slab should be 1 cm greater than the distance between the rafters, and the thickness selected for 2 - 5 cm smaller cross beams. Prerequisite will be a gap between the insulation and roof to air currents can circulate safely. You should also not forget the insulation on the attic floor, may be used or bulk materials or rolled materials.
