Hot tub cover is a necessary accessory for hot tub installed in the open air in the courtyard of a cottage. The main function of the cover is to protect the bowl from the penetration of small debris, leaves or precipitation (snow, rain, hail) into it.
There are some features making a good coating for hot tubs or swim spas. They include the following:
- Foam density. These counterflow covers are 1lb, 1.5lb, and 2lb density. The higher density keeps more heat. And they last longer and are more reliable.
- Foam thickness. The thickness of these swim spa covers ranges from 4 by 2 inches to 6 by 4 inches. Thicker foam layers retain heat and withstand heavy loads.
- The R value. This is an indicator of efficiency in preserving heat.
- Marine vinyl. This is usually the standard material for most covers. It perfectly withstands the effects of water. However, it may vary in quality. Values can range from 26 to 34 ounces. More durable vinyl provides better UV resistance.
- C-channel. It is a galvanized steel bar running centered along the width of the jacuzzi cover. It strengthens the cover under pressure. This bar must be resistant to corrosion.
- Safety locks. The outdoor jacuzzi must have a cover with security locks. They are especially important if you have young children. Their second purpose is to protect the coating from gusts of wind.
Use these tips when choosing a cover for your hot tub, swim spa or a simple outdoor swimming pool.
