8 Epic Storm Shelters for Sale: Underground & Above Ground
Storm shelters are a pretty formidable asset to have in the backyard. More recently, in some parts of America, storm shelters have been the saving grace for both homes and businesses who are regularly affected by severe weather scenarios, but for some, they also represent safety against threats posed by man.
So what exactly are they? They’re essentially an in-ground (or a well-constructed above-ground) unit that provides protection from natural disasters. Sure, some have resorted to doing DIY shelters or rely on their basement as a method to seek shelter from severe circumstances, but with both of those comes the risk of becoming flooded, unstable, or, in the case of some DIY shelters, not being architecturally sound enough to support the earth above it.
While it may seem like a cheaper route to build your own shelter, there are a number of things that can go wrong, and when you are sitting in it with your family, you want to make sure you are completely safe and sound. To ensure manufacturers only make storm shelters that are completely weather resistant and safe, they must comply with a set of standards known as the FEMA Standards which are to ensure that the design and construction of residential and community safe rooms and storm shelters will protect people during extreme-wind events such as tornadoes and hurricanes. It should be noted that these are not verified to withstand nuclear attacks in comparison to what an underground fallout shelter would.
The FEMA standards for shelters don’t just cover tornadoes and storms, they are also a method of protection for other natural circumstances or manmade threats such as safety from shooters and burglars. According to FEMA’s guidelines, safety storm shelters and safe rooms for your home or small business can:
- Help provide “near-absolute protection” for you and your family or employees from injury or death caused by the dangerous forces of extreme winds.
- Provide Near Absolute Protection to the occupants of a safe room.
- Ensure safe room occupants will have a very high probability of being protected from injury or death.
Households with adequate space in their garage or backyard are the most suitable for these structures as they do require some space which varies between each one. However, these are also suitable for businesses and companies that might be situated in areas prone to serious storms, tornados, and disasters, or that may have other risks such as manmade concerns. Residents in Oklahoma would fare well since authorities provide a reimbursement on storm shelters built in specific areas.
So let’s take a look at the 8 top storm shelters that can withstand extreme weather events.
Swisher Safety Residential Shelter
As far as space and capacity goes for value, the Swisher Residential Shelter has the best value. It is one of the cheapest available online, and houses up to six people in its 84″ by 39″ spacing with a reasonable height at 80″.
This is also one of the easiest storm shelters to set up as it is an above ground unit, so there’s no need to pay for excavation or have to dig your own pit for the structure. The structure is fixed by bolts, so if you decide to relocate the shelter it’s as simple as unbolting it, moving and rebolting.
The structure uses emergency panels for a quick exit and has a quick release sliding door so that if there is any debris outside, you are not pinned in the shelter trying to get out. The designers have also included:
- Shielded air ventilation for uninterrupted air flow
- Seats
- Shelves and gun rack
- Firm locking mechanism
- Anchor bolting to the flooring
- Shelter material that is 3/16″ thick
But does it comply with standard storm shelters guidelines? Yes. The Swisher has withstood testing of nine 15lb weights traveling at 100mph being fired at the shelter, so if you are in a tornado, it will withstand any impact thrown at it from up to 250mph winds. As for the FEMA standards, it exceeds their requirements. However, these shelters are not waterproof.
If you are wondering whether this type of shelter can protect you from threats posed by other people, yes it is also designed to be a safe shelter from manmade threats.
