How to insulate the roof of the garage
A garage with a reliable roof structure is a dream of every motorist . It can comfortably accommodate and , slowly, to do the repair or auto tuning . That such conditions have become a reality , two conditions must be met : to establish a system of heating and insulation to perform construction garage.
Before you insulate the roof of the garage , you need to choose the best type of insulation material that best fit under the roof structure and climatic characteristics of the region .
Technology pent roof insulation
Most garages are equipped pent roof , which is the most economical and easy to install and further exploitation. The basis of this design – wooden skeleton system, consisting of a certain section of the boards , based on mauerlat . It is desirable to provide a quality roof insulation still in the process of its construction . Then the heater will be part of the roofing of the pie , which protects the interior from the cold in the winter, the heat in the summer , condensation with significant variations in temperature and humidity.
For the garage roof insulation should be prepared :
Fiberglass insulation (Isover, Ursa); or rock wool ;
vapor barrier ;
construction nails and buttons ;
carpentry tools ;
adhesive tape .
Wood rafters are generally at a distance of 60 cm from each other. This is because the width of the rolls in traditional insulation mats or – 61 cm Technology margin allows web tightly without gaps included in the gap between joists .
Initially, between the rafters fixed to the inside of the garage is a vapor barrier . Fixing is carried out by construction of brackets or buttons. Be sure to get a perfect seal layer vapor barrier. For this material carefully glued joints adhesive tape. Vapor barrier inside the garage will be protected by any kind of finish: paneling , fiberboard, gypsum board , finishing panels , etc.
Outside laid between rafters fiberglass or mineral wool with a minimum thickness of 150 mm. Cutting of material necessary, carry out a special building with a knife. When laying achieve very snug joints material.
The edges of the insulation must coincide with the vertical surface of the outer part of the walls . Limit of 150 mm insulation board that is nailed between the rafters . At the upper edge of the board should be flush with the rafters to insulation was protected on all sides by a tree.
Thermal insulation of flat roof garage
If the roof deck on the garage stacked concrete slabs , thermal insulation is performed outside of the structure . For these purposes the foam on top of which equip the concrete floor .
According to the technology , you must first carry out thorough preparatory work. Plate is cleaned from dust , dirt and various sag . The joints between the slabs and abutting the outer walls must be sealed with foam or caulk high strength fiberglass. On top of the prepared surface placed foam strength. Lay the heat insulator to a two- layer Extension with overlap . Between a heater plate can be attached building wrap.
On the insulation layer is laid waterproofing. The best option for the price and quality can serve Roofing films or conventional roofing material . On the prepared bed is installed with a reinforced concrete floor or a special plastic additives . It is also recommended to add a special composition of concrete solutions to avoid frost cracking of the coating.
Roof insulation from inside the garage
For high-quality thermal insulation of the roof is placed inside the inner part of the three layers of insulation: gidrobarer , insulation and vapor barrier . The organization of this ” cake ” can be carried out both on the concrete slab and beam device with a wooden structure . First, the beam must be sewn on the inside of the structure sheeting. Then it is fixed to the waterproofing , insulation and any type of vapor barrier.
It proved is sprayed insulation, conducted by reliable and durable polyurethane foam. This is a quick and effective way , featuring high water resistance , fire resistance and durability. Polyurethane foam during application fills all the voids and seal tightly . An important advantage of this technology is the lack of need for additional layers of vapor barrier. After deposition, the material can be inside the right trim any skeletal systems.
