It is a cloth that covers the entire interior or inner tent and is held so stretched to the ground by winds (ropes leaving the rainfly and are nailed to the ground by stakes), the important point is that the more winds have lashed soil more stable tent in high winds. It is a must for 10 person tents
Some models bring a rainfly that covers fairly carp and others come with extensions or skirts. The latter is preferable, that way you can better protect the tent outdoors setting firmly skirts to the floor, for example, stones.
The most crucial element of double-roof is its waterproof quality: now comes standard with a coating which makes it waterproof and depending on the type and quality of this coat impermeability to rain will be higher or lower. The waterproofing ability of a fabric is measured in a unit called mm water column, it is critical to know the value of this ratio of the tent you shop: recommended minimum values are 1000 or 1500 mm water column, whether to use the tent in snow or heavy rains conditions 3000 mm water column are advised.
Note that if the rainfly covers well, the whole tent is only necessary that the cloth has a right level of waterproofing and not so much the inner wall of the tent.
When you placed the rainfly see that they are not wrinkled or wells where water can collect (which in this way could cross the rainfly) and above all, we must try the cloth not touch the fabric of the inner wall of the tent areas.
Another thing to consider is the color: light colors best reflect heat and make it more enjoyable, while letting in more light making the illuminated interior (with dark colors is the reverse of the above and in the days indoor temperature high sun would be advisable to set up the tent in the shade). Some models come with an aluminized we can use to regulate heat and UV filtering outputting the aluminized layer.
Seams in all fabrics made of carp are a crucial point because it is the place where you can get water when it rains, not much good without adequate waterproof fabric seams. We need to look to be second and sealed or heat sealed, so water does not pass.
III) Inside the tent or cabin
It is the room of the tent itself, above which will put the rainfly. Inside are two parts:
A) The floor: which is usually polyester or high-density polyethylene to withstand the land on which rests.
Although normally the material is sufficiently impermeable and resistant to the ground where it will support it is highly recommended that we take care of the floor because in the case of breakage lose the insulation inside the tent.
That is always good to carry a canvas or nylon to put under as reinforcement and protection against soil moisture (usually this piece of cloth is not included in a tent, but you can easily get).
An important detail that should be the floor is a socket, meaning that this part of the store that is reinforced does not end at floor level and have some height. This is very necessary in the case of rainfall and have water flowing or running around the tent.
B) Internal wall: usually any of the materials listed above, what we need most of this fabric is breathable, this means that let out moisture as steam through it even if we closed tent, what water vapor? Exhale when we breathe which you perspire or if this gas does not leave the store will then condense on the fabric and will end up licking it, which is something that should always be avoided.
It is also good that we at least screens on all openings and are several to keep the interior always ventilated weather permitting.
Rods are fiberglass or aluminum that form that give structure and shape the tent. The stability of the tent in front of the curve- much intensity will depend on the quality of these studs and quantity it is always better to a higher amount.
V) Tensioners or Winds
The ropes are leaving the rainfly and the inner wall, are necessary for all fabrics are well extended, they must always be taut (but not excessively) and unwrinkled.
The more we have in winds much better tent, as if wind or rain will help keep the tent in form. If you do not have enough so, we can add more wins ourselves. Remember that the pins were securing the tensioners must be nailed to 45 ° on the ground.
VI) Apse or forward:
A portion of the rainfly or inner tent protruding form as a prelude to the interior, this extra space is used to leave backpacks, or changed before entering the tent and more than anything to cook with a heater (a task that should always avoid making inside the tent). The igloo tents usually bring an apse, but it is possible and advisable to buy one separately.
