How to insulate outdoor floors: instructions forinsulation of the external flooring. From DIY to products to use for insulate outdoor floors.
With the flooring correct and correct installation, it should not be necessary to further insulate external floors. The flooring for gardens and exteriors are created to withstand water and bad weather. However, if the installation work was not satisfactory or the starting materials were not adequate, it is possible to isolate the external floors with ad hoc works.
When i outdoor floors to be insulated are those of the terrace, insulation should not aim only at waterproofing: in this case it will be necessary insulate the floor also thermally. In this circumstance, I refer you to the article dedicated to floor insulation on land or terraces:insulate floors, directions and advice.
How to insulate outdoor floors
To waterproof and insulate an outdoor floor it is important to identify the weak points of our flooring but also to understand what type of insulation we intend to install. If the external floor is the roof (or the terrace), as stated, it will be necessary to insulate it acoustically and thermally. There insulating sheath of an external floor should be installed only after a thorough cleaning of the surface.
A first system forinsulate the external floorconsists in checking the joints, theescapes.Check the cracks and joints between the flooring and the perimeter walls, if you notice excessively large or deteriorated joints, use silicone to seal the meeting points.
This system is ineffective if the problem occurs over an entire surface: if the surface is not tiled, use an insulating sheath, on the contrary, if the surface is tiled, you can insulate the external flooring by applying silicone-based insulating material. It is a colorless (transparent) liquid that is applied with a simple brush. This DIY operation is quite effective for insulating an outdoor floor and at the same time polishing it and making it water-repellent. Silicone-based insulators are compatible with almost all outdoor flooring, especially if in stoneware or terracotta.
Theoutdoor flooringthat host the passage of vehicles (cars or motorcycles) may need a more accurate waterproofing. In this context, it is not appropriate to use insulating sheaths (such as those used for roofs and terraces) or silicone-based spreadable insulators. To insulate floors adjacent to the garage or where cars pass, the use of bituminous material may be more suitable in order to avoid the overflow of water which, in the event of heavy rain, could cause the tiles to lift.
In particularly humid areas, the use of bitumen is also recommended forinsulate external floors of terraces and balconies. In this case, the insulating substance must be applied with a brush and cold or, as mentioned, in the form of an insulating sheath requiring the use of a gas torch to dissolve the material to be perfectly adhered to the various joints.
If you do not intend to buy a torch (on Amazon, a good gas torch to spread roofing on roofs can be bought for about 35 euros), you can request the intervention of a specialized company that will take care of laying the insulating covering. The insulating covering for roofs and terraces consists of rolls that are laid on the flooring to be insulated and then laid with the heat method (using the flame generated by the gas torch).
These just described are the "traditional" methods to insulate outdoor floors, however, today, there are many other materials that give excellent results. This is the case of epoxy mastic which is first spread on the ground with a special tool and then, when solidified, takes on an appearance similar to that oflinoleum.
Among the outdoor maintenance jobs, don't forget to insulate the external walls of the house and the perimeter walls of the garden:how to waterproof a wall.
