How do you put insulation in a flat roof?

Thermal insulation for flat roofs

What materials can we use as thermal insulation for roofs and maintain the temperature of our home? When winter or summer arrives and we have to turn on the heater or air conditioning, we are worried about the energy leakage that may exist.

The roof is one of the places that can have more energy leakage, placing a proper thermal insulation layer can save up to 25% of energy. Living in a more comfortable environment at a lower price depends on some improvements in the roof of our house.

These 4 materials are the most used for the roof of a family house. They protect us from rain, cold, sun and danger. However, in some regions of the country we may need an efficient roof insulation to live comfortably and save energy inside. Consult with the best construction professionals.

By day, the dark shade will absorb all the sun’s energy and at night it will continue to emit the heat absorbed during the day as if it were a radiant slab. While a light colored paint will reflect the sun’s rays and heat, keeping the interior environment a little cooler.

What is the best insulation for sheet metal roofing?

Aluminized foam : it is the most economical thermal insulator we can find. It is polyethylene foam covered by a thin layer of aluminum 5mm or 10 mm thick. Aluminum maximizes the heat insulation possibilities of your metal roof, already present in the foam.

How to insulate the ceiling from the cold and heat?

The best in this case is to place layers of expanded polystyrene, glass wool or rock wool. The thickness should be at least 90 millimeters so that the difference can be noticed, and the layers are placed as in the previous point. Currently there is a very effective method to insulate a roof from cold and heat.

How do you insulate the roof of a house?

An effective way to insulate a ceiling is to place rigid layers combined with soft ones (cork, expanded polystyrene…) fixed to the existing roof. Normally, the soft or spring elements are glued with contact glue and the rigid elements are adhered as a false ceiling.

Roof Insulation

Underneath the sheets of your roof you are going to start blocking the entry of heat through the incorporation of a thermal insulator. This insulation can be either regular thermal insulation (aluminized polyethylene) or glass wool. Both will prevent, through their properties, that the heat enters with all its force to your house, in addition to other benefits. There are different varieties of insulators and wool, here are some of them:

Aluminized foam : it is the most economical thermal insulator that we can find. It is polyethylene foam covered by a thin layer of aluminum 5mm or 10 mm thick. The aluminum maximizes the possibilities of insulating your metal roof from heat, already present in the foam. An example of this type of insulation is AMAFREN’s H5 and H10.

Multilayer: is an innovative 5-layer system that offers greater resistance, greater thermal insulation and triple insulation against rain on your sheet metal roofs. On the other hand, it favors the ventilation of your rooms thanks to the ventilation rods that are among its components.    An example of this type of insulation is ISOLANT’s TBA Multilayer.

In this case, we highlight fiberglass. This insulating material is used with a higher density in areas that require greater resistance to compression. This is the case of floors or facades, to give you a practical example.

How to insulate the heat from the roof of sheet zinc?

To insulate the temperature of the roofs you should use mineral wool, glass wool, polyester insulation or high density polystyrene. In addition, you should consider gypsum board to cover the false ceiling.

How to insulate the eternit roof from the cold?

Between the Eternit roof and the ceiling we must install the most recommended heat insulators such as yellow or pink fiberglass, rock wool, polyester wool.

What is the best thermal insulation for roofs?

There is no point in turning up the heating to the maximum. What we need to do is to insulate better: we must take note of this to improve the energy efficiency of our home. When carrying out renovation work to improve insulation, start with ceilings and roofs, the main places where heat leaks, up to… 30%! Therefore, with the insulation of the roof we will achieve savings of 30% thanks to lower energy consumption. But why is roof insulation a priority?

What is the best insulation for wood ceiling?

Blanket type

After this blanket, it is suggested to place a glass wool as thermal insulation; it is recommended that its thickness is not less than 50 millimeters, in order to achieve a better protection.

How do I make my house thermal?

A green wall or vertical garden. If you want natural thermal insulation, which will cool the interior of the house as well as give it a new look, a vertical garden is the solution, place it on the wall that is most exposed to the sun and radiates more heat into the rooms.

What is the most economical thermal insulation?

Cellulose fiber is cheaper, easier to inject and much more environmentally friendly because, compared to polyurethane, it requires very little energy to manufacture.

How to insulate a slab roof from heat

There are many flat roofs waterproofed with a bituminous membrane with slate self-protection. They are usually roofs resolved by means of a double membrane totally adhered to the existing support. The support is composed of a system of slopes by means of cellular concrete, arlite or in any case a concrete with very little mechanical resistance, since the function of this one is not other one that to facilitate the runoff of the water towards the drains.

The quickest way would be to place a filter tile over the waterproofing system. If we are going to re-waterproof the roof, by placing an element on top, it would not be necessary to use a self-protected membrane, so a bituminous membrane could be placed adhered to the existing slate. To facilitate this fusion process, it is recommended to apply an asphalt primer, after cleaning up the areas where the original sheet was hollowed out from the substrate. In any case, the filtering tile must be installed on a geotextile that protects the waterproofing membrane from possible puncturing.
