Waterproof Foam Insulation Sheets

Neoprene foam can be produced in either closed cell or open cell form.

Waterproof foam insulation sheets.

Expanded polystyrene or xps extruded polystyrene or eps and polyisocyanurate or polyiso are the three main types of rigid closed cell insulation materials. Water resistant closed cell foam sheets are panels of synthetic material that are commonly used as package inserts and insulation. Foam board insulation is easy to use and is a great diy way to add some insulation. Spray polyurethane foam spf is used as insulation inside building walls on temperature controlled transportation equipment on roofs on tanks on portable or temporary structures.

Insulated foam sheets are also used as an insulated sheathing underlayment for exterior siding. Waterproof rigid insulation is used on roofs. As waterproofing in wall spaces attics and on roofs.

Each type is used in a variety of applications and under conditions where resistance to water and moisture is critical. Typically sold as sheet insulation in a standard size of 4 x 8 foam insulation panels can help reduce energy costs get a handle on moisture control and more. It comes in standard size 4 8 sheets and smaller sizes in many different thicknesses from 1 4 inch to 2 inches. The closed cell form is waterproof because it contains gas nitrogen cells.

The foam is made up of cells that are closed off from one another to resist water penetration and provide thermal insulation. By manufacturing neoprene with nitrogen gas the material becomes more insulated and makes the material very buoyant. A flexible water based one component foam designed to form an interior gasket between framing lumber and drywall to improve air sealing performance.

As an air barrier in commercial industrial and residential construction. This eliminates thermal bridging which is the energy lost through wall studs. The panels provide a continuous energy efficient surface. The studs conduct more heat than the insulation between them.

Polyisocyanurate is another option coming in as the densest and more expensive option for foam board.
