Comfort in a summer tent
You will only be able to escape the heat if all elements of the tent are adapted to cope with high temperatures and solar radiation. A good summer tent is cool but not stuffy, it provides protection from the heat, UV rays, insects and from the rain.
Tents made from natural fabric
Breathable canvas, made from only natural cotton and linen, is the most suitable material for the outer tent. This combination provides natural cooling and fresh air penetrates through the fabric, which does not retain moisture or carbon dioxide. You can check the fabric by trying to breathe through it. The light colour of the half-linen canvas heats up less in the sun than bright synthetic fabrics such as Polyester or Oxford (for example, this is how it looks on camping tents). The main condition when buying a canvas summer tent is the presence of waterproof and anti-rot treatment in the material. After all, the tent should also protect from the rain, but the lack of anti-rot treatment will cause the fabric to quickly rot because of its natural content. Check with the manufacturer which canvas was used to produce the tent. Item 11252СКПВ produced by Vladimirsky Textile is the best canvas currently available on the Russian market.
Circumstances when fabric with PVC coating is recommended in the summer
If there is a high probability of heavy rain, then we recommend that you buy a combined summer tent. The roof of the tent is made from double-layer PVC coated fabric (more information on PVC)and the wall is made from canvas. This looks like the logical option: PVC will protect against any downpour; a PVC roof is impermeable to water and has no seams (in canvas roofs seams may provide «doors» for water if the incorrect threads were used to sew the fabric). PVC sheets are welded together using heated air. Tents made entirely from PVC coated fabric are used when air conditioning is required, for example for an operating theatre in a medical tent. In such cases, PVC ensures that the tent is sealed and cold air supplied by the mobile air-conditioner remains inside the tent.
Protect your summer tent from UV rays
Ultraviolet radiation can gradually damage canvas. The outer tent can be protected by an awning (canvas or polypropylene mesh), stretched on poles or between nearby trees, attached to the tent at a height of 20 to 25 cm (when it is no longer good enough, it is easier and cheaper to replace than an outer tent). The air layer between the awning and the roof also prevents air in the tent from heating.
A summer tent should have two layers
The inner tent helps to significantly reduce the heating inside the summer tent. This is due to the layer of air that forms between the outer and inner tents. In particularly hot climates, this layer of air is crucial to maintaining a comfortable atmosphere. Bleached calico is generally used as the inner tent fabric. It is sometimes sensible to use more expensive material, such as Discret-O.
How to ventilate the tent
Although both summer tent layers should allow air to pass through them, there are several other ventilation methods. If the tent has two exits at opposite ends, then it is easy to create a current of air (like in the Pamir 30 tent). Ventilation holes with flaps are usually provided in the end walls (at the top where air heats quicker). Ventilation can also be provided through windows and by rolling up the lower edge of the outer tent. All summer tents sold by RPC OFT have fasteners attaching the outer tent while airing the tent. Don’t forget that warm air flowing freely through the tent will heat it up. Therefore, in hot weather it is sensible to keep the windows and entrances tightly closed.
Windows in a summer tent
It should be possible to remove or roll up windows in summer tents. PVC plastic is very suitable for summer tent windows. However, this clear window plastic can be easily damaged. RPC ORT provides removable welded windows for its tents. Using a high-frequency machine, a cruciform PVC insert is welded into the transparent plastic. This serves to prevent the plastic window from straining when twisted. The window is placed in the same way in a PVC frame, which has a hole for fixing it to the window frame. The window not only withstands bending better, but can be easily removed for storage or replacement (most tents that are currently produced have windows that are tightly soldered to the inner tent, which prevents airing, makes it difficult to store them carefully and makes it harder to replace them).
In addition to the standard light-protective curtains and plastic windows for summer and winter tents, the summer window kit includes a mosquito net. The ventilation holes on the end walls also have mosquito nets. Mosquito nets are also used in camping tents for panoramic windows (such as the Headquarters and Camping tents).
The waterproof tent floor is a sheet of PVC coated material. It can be a separate element, tightly fastened to the outer tent or it can be joined to the outer tent as a single unit. The attachable floor has sides that turn upwards, protecting the tent from water, as well as fabric pockets for inserting the frame’s poles.
Wind is the main test for summer tent frames
The summer frame is made from round metal poles. They carry weight very well, even if the tent is completely soaked. In windy weather, the frame can be strengthened with additional ties (steel cables stretched between structural elements) and additional end poles preventing the tent from collapsing. In particularly windy conditions, a winter frame can be used which has shaped poles.
