Precious heat flies into the pipe? This means that you simply did not take care of it in time, because it accounts for about 40% of the total heat loss! Quite an impressive amount that you overpay for heating every time. Wouldn't it be better to invest in a one-time investment in Rockwool Roof Butts insulation, which will make your roof a reliable guardian of heat in the house, and save money over the next 50 years?
7 main advantages of RUF BATTSA - be the first to know about them!
Roof butts insulation - 5 types that conquered the construction market!
For insulating flat roofs, the most commonly used products are Rockwool Roof Butts, which are characterized by increased rigidity. Hydrophobic insulation boards are made of stone wool based on mineral basalt rocks. Rigid insulation is used in ceilings as a heat and sound insulation layer, including when installing roofs without using cement screed.
The combined structure of RUF BATTS EXTRA and RUF BATTS OPTIMA slabs eliminates the need to install two layers of thermal insulation, which greatly simplifies the installation of the system and shortens the commissioning period up to 30%.
The use of slabs allows you to avoid a thinner slab layer during the installation of the structure, and also completely eliminates errors in transport logistics and delivery of goods to the client.
Why are consumers increasingly choosing Ruf Butts?
Due to the high quality of basalt fiber, the Rockwool RUF BATTS thermal insulation has high strength and a fairly long service life. The minimum coefficient of thermal conductivity allows you to create maximum protection against heat loss. Thermal insulation boards RUF BATTS differ in a number of advantages that allow the manufacturer to be always one step ahead in the thermal insulation business.
Depending on the subtype and due to their high rigidity, roof butts find their application in a wide variety of construction areas. This can be soft-type roof insulation, which excludes the installation of a cement screed and the impossibility of using lightweight boards. Insulating materials RUF BATTS can be used as an upper or lower layer of heat and sound insulation when installing a single-layer or multi-layer "roofing cake". In terms of physical and technical characteristics, they fully comply with the existing GOST and surpass similar thermal insulation materials from other manufacturers in terms of reliability and durability.
By purchasing thermal insulation boards RUF BATTS for the roof, the client receives the minimum thermal conductivity and maximum protection against heat loss with a sufficiently high strength of the coatings. Super-rigid slabs have excellent strength characteristics, their main task in the system is to protect the thermal insulation layer from shock loads during the operation of the roof.

One of the elements of the building, where large heat losses occur, is a flat roof. To reduce heat loss, Rockwool offers several types of basalt mineral wool-based insulation: Roof Batts (), Roof Batts B (Roof Batts B), Roof Batts C (Roof Batts C), Roof Batts EXTRA (Roof Batts Extra) and Roof Batts OPTIMA (Ruf Butts OPTIMA).
Roof Batts slabs are slabs of increased rigidity, with a density of 160 kg / cubic meter, intended for roof insulation without a cement screed.
Slabs Roof Batts B and Roof Batts H are used for thermal insulation of roofs with two-layer insulation without a cement screed. Roof Batts H - rigid slabs of the lower base layer of insulation with a density of 115 kg. Roof Batts B - very rigid mineral slabs with a density of 190 kg / m3. designed to protect the base layer from mechanical damage.
Roof Batts C - rigid slabs with a density of 165 kg / cubic meter, - are used for thermal insulation of roofing systems with a protective concrete coating, cement-sand screed or sand and asphalt concrete protection.
Roof Batts EXTRA and Roof Batts OPTIMA slabs have a combined structure and differ from each other in the density of layers, thermal characteristics and other parameters.
Editing Roof Butts
When insulating the roof, it is necessary to protect the mineral wool insulation from water vapors penetrating into its structure from the building with a layer of vapor barrier film.
Insulation materials are attached to the roof slab, as a rule, mechanically with special disc-shaped fasteners, or in some cases they are glued. Loose insulation on a flat roof, for various reasons (vibration, mechanical stress, etc.), begins to shift, resulting in the formation of "pits" and a rupture of the roof carpet.
Mineral wool slabs of these types are intended for roof insulation with the subsequent use of a bitumen-deposited or polymer-membrane waterproofing carpet.

If you believe the general statistics, then almost every fourth house in our country has a flat roof, which is covered with roofing material and. And every second house is equipped with an attic.
It would seem that the floor slab, which is the basis for a flat roof or attic, should perfectly protect the interior of the house from heat loss. Unfortunately, this is not always the case. Although concrete is a rather powerful barrier, it cannot provide thermal insulation by itself.
Therefore, manufacturers of building materials produce special types of insulation, whose specifications designed to process flat roofs and attics. One of these insulation materials is Rockwool Roof Butts.
1 Features and purpose
Flat roofs are mainly used in industrial buildings. This is due to the peculiarities of their design. Industrial buildings are long and have a huge number of spans.
Such constructive solutions are a necessity, since a large number of equipment and people must be conveniently located inside the building.
At the same time, a large roof area with makes the creation pitched roof unprofitable. Too much money will have to be spent on creating the rafters, the basic elements.
Yes, and the coverage itself will have to be spent, and very significantly. Just imagine how much finishing will cost even with slate sheets of one workshop, the area of \u200b\u200bwhich is not less than several hundred meters. The numbers may seem astronomical to you.
Laying the same floors allows you to create a roof of a cheap sample, which, moreover, also handles its tasks well. The problem here is that a flat roof isn't an attic after all. In terms of thermal insulation properties, it is simply not capable of competing with him.
And if the problem of waterproofing can still be dealt with by laying roofing material, then the situation with thermal insulation is more complicated.
The plates themselves are too weak a barrier to cold. In winter, they quickly freeze, and if a dense layer of snow has not had time to fall on the roof (snow can guarantee temperature stabilization due to its own thermal insulation properties).
That overlap begins to cool quickly and give its temperature inside the room. Turning to physics, we understand that warm air is always at the upper levels of the building, even if it is. When it cools, it sinks, being replaced by a warmer one.
If the roofing ceilings will freeze strongly, then the so-called reheating process is organized in the house, when air circulation does not heat it up, but, on the contrary, even more cooling.
In such a situation, even the use of powerful heating systems will not give sufficient results. After all, you, in fact, will "fight with windmills", trying to warm up too cold air.
And this problem can be solved much more trivially. It is enough just to use insulation made of mineral wool boards or rolls. In particular, Rockwool Roof Butts insulation. It is a material made of mineral wool slabs that have a basalt base.
Plates are very well suited as a material for thermal insulation, as they have appropriate technical characteristics. Rockwool has made sure that their products and products are competitive.
It is very convenient to use the slabs, they are easy to assemble and are specially designed for the arrangement of high-quality thermal insulation of flat roofs, as well as attics, of the exploited and unexploited type.
2 Characteristics and properties of insulation
So, let's pay attention to the specific technical characteristics, which is shown to us by the sample of Ruf Butts. First of all, its increased density is striking. Indeed, the density of these plates is at the level of 135-180 kg / m 3. Insulation materials have such indicators, which can be listed in a matter of seconds.
However, such a density is not always needed, but in the matter of insulating a flat roof using mineral wool slabs, the strength of the slab will directly affect the operation of the entire structure.
After all, the insulation must be able to withstand the loads from human weight, the weight of atmospheric precipitation (especially snow), etc.
The second important parameter, the ability to withstand high temperatures and not be damaged by direct ultraviolet rays. Plates are able to withstand temperatures up to 1000 degrees Celsius, and even after exceeding this mark, they simply begin to slowly collapse, but no fire will occur.
Protection against contact with water also has an effect. In the arrangement of flat roofs, it increases exponentially. It is unlikely that when working with mineral wool insulation, one can recall the technical characteristics, which will be as important as good resistance to moisture.
In this regard, Ruth Butts has an enviable position. The boards do not absorb moisture at all. Their water absorption coefficient is only 1.5%.
This means that even when completely immersed in water, after a while the stove will absorb only 1.5% of the liquid, in relation to its own volume. Moreover, this amount of moisture is so insignificant that it can erode over the next few hours.
2.1 Types and differences
They produce insulation Ruf Butts in several varieties. They all have their own purpose and differences. It is important to take into account the differences between the types of insulation, otherwise you may face an excessive waste of funds. And this is already useless.
So, Ruf Butts is produced in the following varieties:
- Rockwool Roof Butts N;
- Rockwool sample by Roof Butts W;
- Rockwool Models Roof Butts S;
- Rockwool Roof Butts Extra;
- Rockwool Roof Butts Optima.
Rockwool Roof Butts N is intended for arranging the lower level of roof insulation. This is a kind of base for a layer of insulation. Roof Butts N slabs are not so strong, they can withstand average loads, but they are cheaper than standard models.
Rockwool model Roof Butts B is used as a top layer of insulation. Accordingly, such plates are produced in a very rigid form and with a thickness that is only 50 mm.
But Ruf Butts C is used when processing exploited attics that they plan to fill sand screed... The insulation adheres well to the future solution and forms an extremely reliable structure.
2.2 Flat roof insulation technology
Since Ruf Butts was conceived in advance as an insulation material for the roof, it is very easy to work with it.
Indeed, you can lay the material using the simplest tools, and it won't take you much time to work.
Stages of work:
- We prepare the base.
- We mount the first level of slabs with mortar.
- We mount the second level of slabs. We lay the slabs with an overlap, observing the offset, so that air bridges do not form.
- Additionally, we fix the insulation with disc dowels.
- We mount the waterproofing layer.
- We lay roofing material or any other covering. Roofing material can be replaced with a screed.
If you use different insulation materials, for example, Ruf Butts N and Ruf Butts B, then, respectively, lay the first model as the bottom layer, and set the second higher.
The Extra and Optima models must first be inspected to determine the location of the base and coating. Only after completing the above procedure, you can proceed with the installation.
2.3 Installation of Rockwool Roof Butts slabs (video)
Rockwool boards are manufactured according to the dual density principle. As a result, Rockwool products have been proven to have such characteristics as low weight, which, in turn, creates ease of installation.
Density
B has the highest density - 190 kg / m3. It is followed by Roof Butts slabs with a density of 160 kg / m3. The “procession” is closed by the brand Ruf Butts N - 115 kg / m3. It is known that the density of a quality material used for thermal insulation should not be higher than 250 kg / m3. Otherwise, the load on the structure increases significantly. In addition, the lower the density of the material, the better its thermal insulation properties are considered. Thus, the density of water-repellent slabs from the manufacturer Rockwool allows not only to save the roof structure without making it heavier, but also to keep warm under the roof.Compressive strength
Compressive strength is an important characteristic of roofing materials. It shows the ability to resist destruction under the influence of external factors that cause deformation and internal stress. Strength thermal insulation materials its structure, core strength and porosity affect. The most compressive strength is the Ruf Butts B line - not less than 70 kPa. The least durable is the Ruf Butts N brand with at least 35 kPa. But this is enough for it to serve as an intermediate layer between the coating and thermal insulation of Ruf Butts B.Thermal conductivity
This characteristic determines the amount of heat transferred over a certain period of time through a certain area of \u200b\u200bthe isothermal surface. Hydrophobized thermal insulation boards are a porous material, therefore thermal conductivity depends on their density, type, size, pore location and other factors. The higher the ambient temperature, the higher the thermal conductivity. During operation, humidity is also important. For this indicator, the Ruf Butts slabs are almost equal, as shown in the table below:Peel strength of layers
According to a study by German scientists, during operation, this indicator decreases three times. The minimum standard value is 5 kN / m2. As you can see from the table, Roof Butts roofing slabs exceed this indicator, which means they are an excellent thermal insulation material.
Vapor permeability
You can estimate this indicator in the lines of Ruf Butts in the above table. The coefficient of all plates is the same. Therefore, when choosing roofing material it is worth paying attention to other characteristics in the table.Conclusion: Rockwool boards have low thermal conductivity, high vapor permeability, strength, elasticity, which determines their long service life.
