More than 100 people have already signed a petition to the Federal Trade Commission to force companies to stop using polyethyl, a highly flammable liquid used to insulate roofs, windows, and other building materials.

The petition says polyethyl is being used to protect against “heat stress” and that it’s not safe to use on a home.

The FTC has been studying the material for months.

It’s called polyethyl-coated polystyrene, or P-CEPS, because it’s made of the same plastic that was used in the iconic movie poster.

It can be sprayed on a roof, painted on the windows, or sprayed onto concrete, said Michael DeGroote, a staff attorney with the consumer protection division of the FTC.

If a company makes a claim that polyethyl isn’t a safe material, it can face fines and civil penalties.

The company’s use of the material in homes is common, according to a report by the National Association of Home Builders.

About 50% of all U.S. homes have at least one window in their front yard, the group said.

The National Association also said in its report that polycarbonate is more expensive to build than PVC, and that most home building is done on a modular system, where a structure is built on the same foundation as the surrounding buildings.

“PVC is just a big mess,” DeGrootes said.

“If you’re going to build a house in a building, you’ve got to use a lot of the materials.

Polyethyl-foam is a good example of what you’ve been seeing.”

The material is also used in paint for roofing and in windows to protect them from the elements.

If the building is constructed using this type of material, the materials can also be easily broken down and reused, said John Bessinger, director of the National Institute for Occupational Safety and Health.

Building codes require that windows, doors, doors hinges, and hinges are protected from moisture.

But some homes don’t have windows, Bessingers said.

If those windows are damaged or missing, it could lead to mold growth in the home.

“They’re just so easy to fix and re-use,” Bessings said.
