Minvata in rolls, what is better than the format in the form of plates?
If an aristocrat decides to walk along the street as a simple philistine, it can still be recognized in the crowd by a kind of polish and some other minor, but still traced signs, like posture and slow movements. Similarly, the mineral wool in coils is distinguished among other types of this product.
In fact, the mineral fiber is quite brittle, but not in the case of a roll version, which embodies many modern technological advances in the processing of materials of this kind. Due to its elasticity, the mineral fiber can roll into rolls or unfold many times, without compromising the integrity of the structure.
The thickness of the roll mineral insulation varies from 50 to 75 millimeters, from 10 centimeters it is already plates.
Depending on the size of the insulated room and, of course, the purpose of the insulation, which can not only be laid on the floor, but also mounted on the walls, you can easily select a roll of suitable sizes. Rolls of 1.2 and 0.6 meters in width are produced. The length in the expanded form of such formats is also different - 10, 8.5, 8.2 meters or less.
The basis of the material is usually fiberglass or a specially processed basalt, which also acquires the fiber structure under the influence of high temperatures. Mineral mass can be covered from one or two sides with aluminum foil or glass wool to create special properties, in particular for increased thermal insulation and wind protection.
Where is mineral wool used in rolls?
Each type of insulation is usually assigned a specific purpose, otherwise, most likely, there would be only one type of mineral thermal insulation for all occasions. That is why, by choosing for yourself a suitable format for fiberglass or, more preferably, a basalt-based heat insulator, keep all the details of the planned insulation in your head.
On the floor, roll insulation should be stacked better in 2 layers, since the optimal thickness is 100 millimeters, which the rolls do not usually have .On the walls, it is possible to mount a mineral wool and in one layer, but it is best to cover it with an additional insulation, at least foam rubber.
It should be borne in mind that it is not recommended to fasten the heat insulation insulator to rafters having a certain angle of inclination, it will easily slip with time. It is better to use basalt slabs for the roof, laying them in the space between the rafters, even in 2 layers for more heat, soto completely cover the width of the rafter feet.
But for rolls, roll coating is ideal, yes, actually, for them it is intended primarily, especially with aluminum coating. Mineral wool in rolls is often used to cover fireplaces, as well as more overall heating systems.
How does mineral wool roll?
It all depends on where you want to put it. On the walls, this material can be fixed with a special glue, while it is desirable to lubricate even the joints between the bands of mineral wool. In addition to the glue for better fixation, mineral wool roll as well as slabs is fastened at five points( four squares and one in the middle) per square meter.
For this purpose, anchors with wide washers are used, which do not allow the mineral wool to slip off the fasteners, even if it is assumed that the glue will not hold it, the probability of which is zero. It is logical that, in addition to other fixatives, the insulation must be firmly pressed against the wall by plaster board panels or by lining.
The floor of the roll insulation is also laid on the previously applied adhesive layer, the only difference is that it is not necessary to use anchors or other hardware such as spacer plugs. Laying a mineral fiber in two layers, try not to forget about the chess order, so the joints of the lower layer will be hidden by the upper rolled mats. In order to save fasteners, five fixing points in this case are more practical to perform through both layers.
