When we prepare the necessary material we never forget the suitable footwear for mountain, the necessary technical clothes, the tent or the food. But ... and the thermal insulation?
The market for thermal insulators offers three main types: inflatable mats, self-inflating mats and EVA foam mats. Each of them offers similar benefits; however, they also have features that differentiate them from each other.
Some of its common characteristics are the existence of different thicknesses or that, how much thicker, more insulated. The market also offers different sizes, which vary depending on the height of the mountaineer or mountaineer.
The self-swelling thermal insulators have the particularity of being like a kind of sandwich which, inside, incorporate EVA foam that when it recovers its shape absorbs air. It is necessary to blow until finding the optimum tension point. They exist of several types: symmetrical (totally rectangular) or asymmetrical. The latter try to reduce space and weight with rounded ends.
There are also those that are made from different tubes that swell to lung. Their great advantage is that they are very light, also offer a very high degree of comfort. Its biggest drawback is that, if you prick, you are forced to rest on the ground. However, the market offers patches for repair in case it is punctured.
Classic thermal insulators built with EVA foam have evolved over time. Its comfort is also very high, and its insulating performance in very cold places are tremendously high. Now, in terms of comfort, self-swelling or inflatable thermal insulation is one step ahead.
The market offers different sizes, weights and resistances; so finding the model that best suits our activity in the bush is capital. That's why Vertic specialists will help you find the key.
R-value How much do the camping mats insulate?
R-value, the isolation rate at bedtime. We usually talk about sleeping bags, their thermal capacity, their comfort, their comfort limit, but ... what kind of thermal insulation do we sleep on? A very important part of the heat leakage is given by the area of ??contact with the ground.
If the floors are cold, are full of snow or especially wet, and the thermal insulation is not built to withstand this type of conditions, the cold or humidity will not let us rest in conditions after a hard day on the mountain.
Therefore, when purchasing a camping mat, it is very important to know its R-value or isolation index. The activity practiced, the moment in which it develops and the thermal conditions of the land are fundamental aspects to choose the thermal insulation that best suits our needs.
If you do not sleep in extremely cold places and are interested in carrying light weight, you can bet on lightness sacrificing a high R-value. On the contrary, in alpine activities or in cold conditions it is advisable to choose thermal insulators with a high R-value.
How high must an R-value be?
A warm R-value is one whose index rotates around four. From four points, and upwards, the mats are designed for winter activities.
The thermal insulators are complementary to the sleeping bag, and allow the sleeping bag to offer 100% of its benefits.
The combination of a good sleeping bag with a bad mattress can turn that night into one of our worst in our lives. On the other hand, a mid-range sleeping bag with a good mattress, in the same conditions, will allow us to rest much better.
