Proper Storage and Handling of Polyiso Insulation

Punxsutawney Phil certainly got it right this year; we have had six more weeks of winter — and then some — particularly in the Northeast. As winter turns to spring, building and repair projects which frequently involve the roof get underway. As you commence these new and re-roofing initiatives, here are a few key considerations about the storage and handling of polyiso roof insulation on a jobsite.

Storage

Polyiso insulation is typically shipped protected by a plastic wrap, plastic bag or both. This factory packaging is intended for handling the polyiso in the manufacturing plant and during transit; it should not be relied upon as protection at jobsites or other outdoor storage locations unless specified otherwise by the manufacturer.

Material delivery should be carefully coordinated with the roof application schedule to minimize outdoor storage. When short-term outdoor storage is necessary, whether at grade or on the roof deck, the following precautions should be observed:

  • Bundles should be stored flat above the ground utilizing included feet or on raised pallets. If possible, the bundles should be placed on a finished surface such as gravel, pavement, or concrete rather than on dirt or grass.
  • Unless specified otherwise by the manufacturer, cover the package and pallet with a waterproof cover, and secure to prevent wind displacement.

Note: Polyiso insulation is fully cured and fit for installation upon delivery. No additional storage time is required.

Exercise care during handling of polyiso insulation to prevent breaking or crushing of the square edges and surfaces. Remove the polyiso bundles from trucks with proper equipment. Other means of mishandling, such as pushing pallets off the edge of the truck or “rolling” the pallet across the roof deck, must be avoided.

Product Application

Polyiso should always be installed on dry, clean roof decks in dry conditions. Follow the manufacturer’s recommendations regarding product application to ensure performance to the intended design life of the roofing system. Apply only as much polyiso roof insulation as can be covered by completed roofing the same day.

Construction Traffic

Avoid excessive traffic during roof construction of or on a completed roof surface. Although polyiso has been designed to withstand limited foot traffic, protection from damage by construction traffic and/or abuse is extremely important. Roof surface protection such as plywood should be used in areas where storage and staging are planned and heavy or repeated traffic is anticipated during or after installation.

Some designers and membrane manufacturers specify the use of cover boards as a means of protecting the insulation. If specified, installers should ensure the cover board used is compatible with all components of the roofing system, is acceptable to the membrane manufacturer, and meets specified fire, wind, and code requirements.

Polyiso roof insulation, like other roofing materials, requires a proper understanding of storage, handling, and application to result in a properly constructed roof system.

Essential Ladder Rack Features

As a roofing professional, you rely very heavily on your ladder for work. Keeping that ladder secure during transportation should be a priority. If you recently purchased a new work vehicle or a new ladder and are in the market for a secure storage solution for your ladder, it’s important to understand all of your ladder rack options before you make an investment.

At first glance, a ladder rack is just that—a piece of equipment that attaches to the roof of your van or truck to aid in the transportation of your ladder. But did you know that different ladder racks have different elements that may benefit you as a roofing professional?

Take a look at some of the most important features to consider when shopping for a ladder rack for your work vehicle:

  • Ergonomics: You use your ladder on a daily basis, if not more! Overtime, all of that loading and unloading can really take a toll on your back, shoulders and overall body. Even if you’re in fantastic physical shape, if you twist wrong or lose your balance while unloading a ladder, you could get seriously injured. An ergonomic ladder rack is ideal for professionals just like you. These types of ladder racks allow users to lower the ladder down to an easily reachable height. No more straining to reach your ladder!
  • Security: When you choose a ladder rack, you will want to make sure that it’s one that will keep your ladder secure during transportation. The last thing you want is to deal with a lawsuit because your ladder fell off your vehicle’s roof while driving. Look for ladder racks with lockable, gripping mechanisms to ensure safe transportation of your ladder.
  • Durability: No one wants to invest in a ladder rack just to have it rust out in a few years. Like with most products, the cost of a ladder rack is often directly correlated with its quality. A high-quality ladder rack may have a high sticker price but, in the long run, its durability and reliability will prove to be more cost-efficient. However, if you’re just looking for a short-term solution, a cheaper ladder rack maybe a better fit for your situation.
  • Versatility: Sometimes you may need to transport things other than your ladder on the roof of your work vehicle because of their size. If this is the case, you may want to consider a roof storage solution that has the ability to secure ladders and cargo. Look for a utility rack that features heavy-duty tie-down cleats to secure loads on the roof while traveling. Ladder racks come in all shapes and sizes with many different features available. So if you’re in the market fora new ladder rack, do your homework before you buy to ensure you’re getting the right product for your trade.
