Types of Rigid Board Insulation We Install

Like it sounds, rigid board insulation is available as a foam panel that can be cut. The sizes most often used are 2 x 8 feet and 4 x 8 feet, but the panels vary in thickness and width.

Rigid foam insulation is mainly used for new construction projects, and in our experience, it’s a great solution for insulating homes and buildings and maximizing energy efficiency.

There are three types of rigid foam board:

  • Polyisocyanurate (polyiso): Polyisocyanurate rigid board insulation typically comes with reflective foil facing on both sides. This makes it ideal for the attic, as the foil helps your home reflect rather than absorb the sun’s energy.
  • Extruded polystyrene (XPS): Extruded polystyrene rigid board panels have smooth, plastic surfaces and are extremely durable.
  • Expanded polystyrene (EPS): EPS rigid board insulation can be used for both new construction projects and re-insulating.

Why Should I Choose Rigid Board Insulation?

Rigid foam insulation’s R-value varies and depends on the type of rigid foam used. Polyiso foam has an R-value between 6.5 and 6.8 per inch. Multiple layers can be installed, which can increase or double the R-value and greatly reduce heat/conditioned air loss.

Installing rigid foam insulation can help:

  • Reduce your utility bills and maximize the energy efficiency of your home or building
  • Make your home or building more comfortable year-round
  • Reduce noises from outside and inside your home or building between rooms and levels
  • Improve the performance of your air conditioner and furnace
  • Contribute to a healthier environment
