baths roof not only protects the building from the elements - rain and snow, high temperatures in summer and low in winter.It has one purpose - to resist the penetration of the steam inside, resulting in a large amount of water poured on the stones, as well as to cover the hot ceiling temperature is often as high as 100 degrees Celsius.Therefore, those who decided to build a bath, be sure to consider how to insulate the roof of the bath so that it was the most steamtight and had good ventilation.
Common variants of the roof for bath ↑
type and shape of the roof for the bath depends on the structure of the project.If the bath room is an extension to the main building, then it is usually equip pent roof.For individual buildings baths optimal solution is gable roof.In this
Why should insulate the roof of the bath?↑
Regardless of roof construction for a bath she must protect the structure from external influences and, most importantly, do not let the heat from the washing and separating the pair.These functions can only perform well insulated roof.If it is assumed that the room will be used only occasionally, it is warm roof can only roofing material or glassine, before decking roofing material.If you plan to use a bath regularly, it is necessary to insulate more reliably.Firstly, it should be protected against rotting all the structural elements by means of antiseptic solutions.Then, in order to fire all the wooden parts to be treated with flame retardants.And only then you can go directly to the insulation.
How to choose a heat insulating material?↑
In the past, the roof of the baths to warm, natural materials such as hemp, moss, hemp, felt.Yes, these materials are cheap, environmentally friendly and have excellent thermal insulation properties, but at the same time, they have significant drawbacks:
- attractive to insects;
- their installation requires a lot of effort.
Currently, developers are used as insulation modern insulating materials:
- mineral wool;
- glass wool;
- mezhventsovogo insulation made from wood chips.
They are resistant to high temperatures, moisture, have high thermal insulation characteristics.An important characteristic for insulation bath is its environmental friendliness.It is no secret that under the influence of high temperature, some plastics emit toxic substances, and in fact in the bath people want to improve their health, not ruin it.
security environment of thermal insulation materials can be recommended mineral wool slabs "Penoplex" extruded polystyrene, felt.Floor loft suitable gravels grit.
Application Method insulation ↑
roof insulation bath using three methods:
- laying a layer of insulation on the rafters.
- laying a layer of insulation between the rafters.
- laying a layer of insulation under the rafters.
to create high-quality thermal insulation layer of insulation must be continuous.We must pay special attention to installation of insulation in places where the pipe abutting the ceiling to the walls, and others. For ventilation, leave a layer of air between the waterproofing material and the insulating layer of the roof.When using fiber insulation is necessary to keep the air gap a bit more as the thickness of the insulation layer is increased in this case, nearly a third.Sometimes the thickness of the rafters is not sufficient to create a normal air gap.Then build up the desired height, using sticks or boards.
roof insulation baths: how it's done ↑
Before starting the roof insulation is necessary to protect designs from decay and heat.To do this, rafters, beams, and roof surface is treated with antiseptics and flame retardants.
On the entire surface of the roof enhance waterproofing material (membrane or polyethylene film).The film is spread out before you install and secure the overlapping crates (10 cm), without tension.
next step - a direct blow heater.The most popular material for thermal insulation of the roof bath - mineral wool.It is a low-cost environmentally friendly material with excellent performance, easy to assemble.
chosen as insulation mineral wool, it is necessary to properly prepare the layer of insulation.Insulation is placed in two rows in a checkerboard pattern (the joints of the lower layer does not have to coincide with the joints of the upper).The optimum thickness of the material - about 100 mm.Then it is placed in roofing pie.With this method of insulation prevents the formation of thermal bridges which occur at overlapping joints.If the roof is not insulated bath during construction and after the bath is ready and the roof is already covered with roofing material, the roof is formed by the same pie, just laying insulation made from the inside, from the attic.
In this case, fixing hydraulic and vapor barrier films and of the insulation will be carried out in other ways.The ideal method is already finished roof insulation bath is laying a layer of insulation between the rafters.The material is placed in mezhstropilnoe space, thus it is necessary to observe the correct sequence of layers of roofing pie.The heat insulating material must be laid right up to the rafters, in other words, the width of the sheet must be equal to the gap between the rafters.When installing insulation is necessary to prevent the formation of cracks and gaps.Steam insulation film is attached on top of the rafters overlapped.If you use multiple layers of insulation, then each subsequent layer is placed so that it overlaps the joints of the previous layer.
ceiling insulation ↑
finished with insulation roof insulation is necessary to do the ceiling.Thermal insulation of the ceiling is also necessary, as it addresses several important issues:
- protects the roof from the attic moisture coming from inside the bath;
- retains heat and steam in the steam room;
- prevents condensation on the ceiling.
insulated overlap in a log bath follows.Spend headliner wooden executioner's blocks with a minimum thickness of 6 cm and lay them in the form of a vapor barrier aluminum foil.Foil overlap and are fixed mounted staple gun and glued seams with tape to protect them from damage.Further, a vapor barrier is placed over a layer of insulation layer thickness of not less than 15 centimeters.If this gravels chips, thickness of the layer must be more than 25 centimeters, so for thermal insulation of the ceiling will need a significant amount of this material.
ceiling must be sufficiently insulated to keep out the hot air from the room bath.At the station exit chimney need to ensure that the distance to the boards of the ceiling is at least 25 centimeters.In order to fire safety edge board is recommended to cover asbestos.
sometimes used for thermal insulation of the ceiling is old, time-tested "antiquated" way - being covered with a mixture of clay and sawdust.The advantages of this method are environmentally friendly and low cost, but such work is rather complicated.If you plan to arrange a storage room in the attic, insulation sheathe the top boards in the case of the cold attic - will be sufficient cement-sand screed.Roof insulation bath is not enough without effective ventilation.Therefore, the attic should arrange the ventilation holes located opposite each other.For the heater air will flow through the air spaces left when laying.This will avoid the formation of condensate therein.
insulate yourself roof bath - activity responsible and challenging, requiring knowledge of many nuances and compliance with certain rules.Therefore, in the absence of practical skills in this business work best left to professionals and then your room will serve its purpose without any problems.
