Nails – the most common type of nail used for hurricane ties is the 16d nail. These are 3 1/2 inches (8.89 centimeters) long and have a diameter of 0.162 inch (0.411 centimeters). You’ll also need some 8D nails, which are 2 1/2 inches (6.35 centimeters) long and have a diameter of 0.131 inches (0.333 centimeters). The number of floor-to-floor connection – this figure will add to the number of straps needed. For example, if you have two floors in your house and four roof-to-wall connections, you’ll need four more straps. To install hurricane straps on an existing roof, you’ll need to remove the soffit. Once removed, you’ll need to secure the connectors at every wall to rafter connection. To do so, secure nails in every hole from the side and front of the strap. Be sure to use joist hanger nails to remain up to code (often stamped 28 on the top of the nail). Locate the clip placement on the trusses. The building code or plan will specify the clip placement. Hurricane straps, also referred to as hurricane clips or hurricane bands, are metal connectors used to secure the roof trusses or rafters to the top wall plate. They prevent the roof from lifting and being blown away during high winds by providing a strong connection between the roof structure and the walls.

In wooden roofs, they also prevent degradation and decay of the timber that could lead to structural failure of the building. Why Are Hurricane Ties So Important? Some load values for the stainless-steel connectors shown here are lower than those for the carbon-steel versions. Ongoing test programs have shown this also to be the case with other stainless-steel connectors in the product line that are installed with nails.

What are Hurricane Ties?

In worse cases, strong uplift winds could even remove the roofs entirely and blow them in the downward direction of the wind. The removed tops can be propelled at speeds so high that they hit buildings in their path and damage property. Hurricane ties come in different shapes and dimensions. It’s essential to choose one that will suit the joint it’ll be used for as well as possible. If the roof’s trusses or rafters will fit into the strap, you’ll need to measure the width of the beams to ensure that they can fit into the opening. A wooden beam serving this purpose is known as a tie-beam and a roof incorporating tie-beams is known as a tie-beam roof. [10] See also [ edit ] Caveat: These are just general guidelines to give you an idea of the steps involved in installing hurricane ties and straps. Always consult with a qualified contractor or engineer to ensure that your home is adequately protected against high winds.

A tie which is attached to roof tiles to keep them from blowing off a roof. These devices are also known as wind clips and hurricane side clips. [5] For simultaneous loads in more than one direction, the connector must be evaluated using either the Unity Equation or the 75% Rule, as described in Straps and Ties General Notes. consequential loss, that you may incur as a result of the non-availability of any item on any date. They work by creating a load path that transfers forces from the top of the building to its foundation When retrofitting existing homes or during the construction of new homes, it’s essential to carefully evaluate the potential risk of high wind events in your area and consult with professionals to determine the appropriate level of reinforcement necessary for your specific circumstances. Retrofitting For Existing Homes: Two Methods For Installing Hurricane TiesIn addition to their role in preventing roof uplift and collapse, hurricane ties can also contribute to overall energy efficiency in buildings by minimizing air leakage, reducing energy loss, and enhancing insulation performance. The Importance Of Hurricane Ties For Structural Stability the Company is satisfied that the defects arise solely from faulty design (other than a design made, furnished or specified by you for which the Company has disclaimed responsibility in writing), materials To install hurricane ties, start by choosing the correct type of tie for your needs, such as the Simpson Strong-Tie H1 Hurricane Tie or the H2.5A 18-Gauge Hurricane Tie. Refer to Simpson Strong-Tie® technical bulletin T-C-HTIEBEAR for allowable bearing enhancement loads. Despite being the faster and easier method, this is not a great way to protect your windows. The Insurance Institute for Business and Home Safety states that using plywood is only acceptable if you need a last-minute solution. The preferred method is to use hurricane shutters.
