Each motorist decides to be engaged in warming of roof of garage or not — for himself. But, you see, repair and service of the machine take place in comfortable conditions quicker, and more qualitatively. Repair works on frost, in cold garage not in the best way can affect health of the owner of car. If to take that amount of time which the true motorist carries out in the garage into account there is obvious need for warming. Garage roof heat insulation, along with warming of gate, floor, walls and also the heating device, gives the chance to be engaged in the car for pleasure, without prejudice to health.
Requirements to thermal insulation materials for garage roof
First of all, it is necessary to decide on the choice of the thermal insulation material, the most suitable under roof design taking into account regional climatic features. Material for warming has to have high rate of fire resistance since the risk of emergence of accidental spark when carrying out repair work is high, from the exhaust pipe. Heater has to be convenient in mounting. Water tightness — one of the main criteria when choosing.
The decision on what — internal or external — heat insulation will be made is accepted depending on stage of “readiness” of garage. If the roof is just built, then it is better to do outside warming and if construction is already operated, then it is necessary to warm from within.
Types of thermal insulation materials
Modern heaters allow to avoid heatlosses, to keep comfortable temperature in garage and also to protect people around from excessive noise. It is possible to allocate the following groups of materials:
- fiber glass,
Excellent technical characteristics are inherent in mineral wool, but there is urgent need for obligatory protection against moisture (vapor barrier and waterproofing), with the device of the “breathing” gap. Mineral fiber flexible and flexible if to compare it to fiber glass material. It is less subject to destruction, has low heat conductivity, also its noise-insulating properties are used. At respect for technology of mounting and the correct protection against moisture, such type of heat insulation will serve long enough.
Often as heater use glass wool which is produced in rolls or plates. Width of such material is equal to rafter step that is very convenient when mounting. Special attention when choosing fiber glass materials is paid to coefficient of thermal conductivity. Higher level of heat insulation will be where this indicator is lower. The small weight of material promotes faster process of mounting. The cost of such heater is rather low. Resistance to any negative impacts and quite long term of operation allow to consider this material one of the most suitable for warming of roof of garage.
The evaporated heat insulation polyurethane foam is very effective. Such way of warming differs in high moisture resistance, durability and fire resistance. Among all thermal insulation materials polyurethane foam has the lowest heat conductivity. Applied on surface, the heat insulator is capable to fill strongly and hermetically all emptiness. Essential plus is that in use of additional vapor barrier there is no need. After sputtering, practically at once, it is possible to start the device of frame system under covering.
Stages of warming of flat roof of garage
If the roof basis — reinforced concrete slabs, then carry out outside warming of design. Optimal variant in this case polyfoam over which there is concrete tie is considered. First of all perform preparatory work where cleaning of plates from different roughnesses, dust, dirt enters. Special attention to joints between plates and to places of adjunction to external walls. All this is filled in with polyurethane foam or hammered with fiber glass.
For the purpose of heat insulation apply polyfoam of the increased durability. It keeps within two layers on the prepared surface. Heater is located with shift of the same kind rather nearby, besides joints of layers should not match. Over polyfoam lay waterproofing. Use roofing material or subroofing film more often.
Further are engaged in the device of concrete tie. It is mounted on waterproofing course. Here either reinforcing is applied, or special plastic additives are used. To prevent cracking of covering, it is quite good to add the frost-resistant additives increasing plasticity and frost resistance to concrete solution.
Heat insulation of lean-to roof
In mounting and the subsequent operation single-pitch roofs are considered as simpler, besides, it is the most economic option. The design represents the wooden frame system built from bars which lean on inferior purlin. It is more reasonable to carry out qualitative heat insulation of roof at stage of its construction. At the same time heater becomes element of roofing pie which will be the barrier protecting the room from overheating during summer time and from cold in the winter. Also will not allow formation of condensate at significant differences of humidity and temperatures.
To warm garage roof, it is necessary to prepare:
- vapor barrier;
- heater fiber glass (Ursa, Isover) or mineral-cotton;
- the gluing tape;
- construction buttons, nails;
- joiner’s tools.
More often the rafter step makes 50-60 cm. This distance corresponds to the traditional width of heater — within 50-61 cm. By means of technology stock occurrence of material between bars is provided dense, without gaps.
Begin with fixing between rafters, from the inside of garage, vapor barrier. It is fixed by means of buttons or construction brackets. It is important to reach absolute tightness of vapor barrier layers. Try to obtain it, gluing joints of material with the gluing tape. Afterwards the vapor barrier from within the building will be closed by any kind of finishing. Apply to these purposes fibreboard, panels, gypsum cardboard, lining and other materials.
From outer end between rafters put heat insulation (mineral wool or fiber glass), not less than 15 cm thick. The main thing to provide dense pressing of material. If there is need for heater cutting, it is possible to use special construction knife.
Edges of heat insulator have to be combined with vertical plane of outside part of walls. Between rafters beat board (150 mm) which will become the limiter for heater. Its upper edge has to be located aflush with rafters i.e. so that the tree protected heat insulation from all directions.
Between waterproofing layer which keeps within on heater and furring under roofing covering, surely leave ventilating gap from two to three centimeters.
How to warm roof from within
That it is the most qualitative to warm roof from within, it is necessary to lay three layers of insulating material: waterproofings, heat insulations and vapor barrier. Such “puff pie” is suitable also for wooden beaming, and for reinforced concrete slabs. Originally from within garage it is necessary to sew up beams with sheet material, and then laying of the listed above insulation layers is carried out.
Let’s consider in more detail heat insulation polyfoam. The way of fastening of sheets depends on overlapping design. If it is made of bars or boards, this heater is fixed by dowels or nails. Then the heat insulator is closed sheet material which is fixed to wooden blank by means of long screws.
If overlapping — concrete slabs, then the framework is necessary for the device of heat insulation. For fastening of framework to plates use metal corners and screws, self-tapping screws. Polyfoam is laid on framework, “take” it adhesive tape, and having pressed sheets of covering, fix.
Warming by polyfoam does not demand performance of waterproofing and vapor barrier since material does not pass moisture. If the fiber heat insulator is used, by all means it is necessary to take care of additional protection against moisture. The waterproofing is stacked from roof, and vapor barrier from the room.
It can heat-insulate roof independently to any owner of garage. Variety of modern materials allows to cope with this task even to the person who is not owning special skills in construction.
