How spray foam is sold: sets, pallets, truckloads, and how a contractor rate works

Spray foam comes as a set of two 55-gallon drums, bought by the set, by the pallet or by the truckload. The price is a per-set rate set for your account rather than a shelf price, paid by card or on NET-30 terms once approved. Here is how to set that up and get material today.

Spray foam is sold by the set, and a set is a specific thing: one 55-gallon drum of A-side (ISO) and one 55-gallon drum of B-side (resin), run through the rig at 1 to 1. Everything about buying it, from the price to the forklift, follows from that.

What you are buying

UnitWhat it isWho buys it this way
SetTwo drums, A and B, about 1,100 lb togetherA crew doing a job a week or less; the top-up for a weekly crew
PalletFour drums, two sets, strappedCrews spraying several sets a week who have a forklift or a liftgate
TruckloadAround 40 sets on a dedicated truckHigh-volume contractors and crews with warehouse space

The weight matters. A set is two drums that each weigh between 540 and 575 pounds by the specific gravities on the data sheet, so pickup means a truck or trailer that can take drums and a way to get them off at the shop.

How the price works

There is no shelf price on spray foam. Each contractor has a per-set rate for each product, set for the account and based on how much you spray, what you spray, and how you pay. The rate is what shows in your catalog once it is set, and it is the price the order is placed at, on the website and by phone. The rate for a set is the same at the counter and on a delivery; the delivery fee is quoted separately.

To get a rate:

  1. Create an account at usafoam.co/signup. Guns, parts and supplies show their price right away.
  2. Ask for your foam rate at usafoam.co/quote: roughly how many sets a month, open or closed cell, pickup or delivery.
  3. The rate is set on your account and the foam sets show it in the catalog from then on.

How you pay

  • Card. Available to every account from the first order and the default at checkout.
  • NET-30 terms. Once the account is approved for credit. The credit application is signed on the site and underwritten by our credit agency; approval sets a credit limit, and open invoices can be paid from the account dashboard by card, ACH or check. A past-due invoice pauses credit until it is cleared, so the terms stay open for the crews who use them.
  • Phone and counter orders go through the same account and the same rate.

Pickup or delivery

  • Counter pickup at the branch that has the stock. Orders are usually ready in 15 to 30 minutes during counter hours; an order placed within 90 minutes of closing is ready half an hour after the branch next opens. The product page and the branch page show what is on the shelf at each branch right now.
  • Hot-shot delivery to the job or the shop, quoted live at checkout by distance and the vehicle it takes: a car for small parts, a cargo van, a box truck, a liftgate truck, a flatbed, or a trailer for pallets. It goes out as soon as the warehouse has the order staged, or you pick a weekday morning or afternoon window.
  • The driver brings a pick ticket; the person receiving signs it on the spot, and that signed ticket is the delivery record on your order.

What to have ready

  • At the counter: a vehicle that takes drums, straps, and the order number from the confirmation.
  • At the job for a delivery: somewhere a liftgate or a pallet jack can set the drums, and a phone number the driver can reach.
  • At the shop: a conditioned corner for the drums, between 50 and 75°F. The drum storage guide covers why.

Reordering

Weekly crews keep a set in reserve and reorder when they open it. The account's order history has a reorder button for the last mix, and the branch page shows stock before you drive. A crew that sprays a set a month buys the set the day before the job and picks it up on the way.
