Insulation board

Insulation boards can achieve a surprisingly high R-Value for such a compact product when installed correctly in the right environments. Unlike other insulation materials, such as fibreglass and cellulose which slow heat transfer, insulation boards can actually create an air barrier and stop air movement completely.

There are many different materials used to create insulation board, so it’s important to determine your desired R-Value so you use the right product to achieve the insulation performance you’re after. Insulation Boards are ideal for tight or cramped spaces where a high R-Value is needed, which can make it somewhat more difficult to install than other insulation options. They need to be placed together tightly, and ideally sealed with tape or caulk to achieve their optimum level.

Types

These are the three most common types of insulation board;

  • Polyisocyanurate (polyiso)
  • Highest R-value P/Inch.
  • Most polyiso products come with reflective foil on both faces. This can act as a radiant barrier in some applications.
  • Generally most expensive option.
  • Extruded polystyrene (XPS)
  • Smooth plastic surface
  • Does not absorb water, unlike polyiso
  • Stronger than polystyrene
  • Most versatile
  • Expanded polystyrene (EPS)
  • Cheapest option
  • Weak, easily damaged

It is important to employ a reputable and qualified surveyor to inspect your building before committing to any type of insulation. Not all homes will benefit from insulation boards so it is important to speak to a knowledgeable expert that can give you qualified advice on your best option.
