Icynene spray foam cavity wall insulation

ICYNENE spray foam cavity wall insulation can be used in a number of ways on external walls.

  • ICYNENE medium density spray foam insulation, ICYNENE MD-C-200™ can be used in masonry cavity walls and behind panelized systems
  • Either ICYNENE MD-C-200 or ICYNENE low density spray foam insulation (ICYNENE LD-C-50®) can be used to insulate the inner side of exterior walls.

Common Problems with External Wall Insulation – Cavity

External wall cavities and panelized systems are sometimes insulated with foam board or fiberglass – here are some issues resulting from using those insulation types:

  • Up to 40% of energy loss is due to uncontrolled air leakage.
  • Up to 99% of moisture travels in the air and can build up inside a building through daily activities. If moisture carried by air is allowed to move through the walls it can condense within the walls leading to related problems such as mold.
  • Drafts causing hot/cold spots.
  • Some insulation types are damaged by water and moisture, which may compromise their performance.
  • Insulation damage during construction and damage by other trades.
  • Joints and penetrations are difficult and time-consuming to insulate, and subject to human error.
  • Difficulty insulating unusual shapes using an inflexible material.

Common Problems with Exterior Walls – Insulating on the Inside

Exterior walls may be insulated from the inside with foam board or fiberglass – here are some issues resulting from using those insulation types:

  • Up to 40% of energy loss is due to uncontrolled air leakage.
  • Up to 99% of moisture travels in the air and can build up inside a building through daily activities. If moisture carried by air is allowed to move through the walls it can condense within the walls leading to related problems such as mold.
  • Joints and penetrations are difficult and time-consuming to insulate, and subject to human error.
  • Insulation can be damaged by water or other moisture, which may compromise its performance.
  • Insulation damage during construction and damage by other trades.
  • Insulation may be damaged by pests.

Benefits of Using ICYNENE Spray Foam for Exterior Wall Insulation

  • Increased energy efficiency.
  • Improved indoor air quality (IAQ).
  • Attenuates noise (ICYNENE LD-C-50 attenuates noise more than MD-C-200)
  • Easily insulates edges and penetrations – expands to fill holes.
  • Can be sprayed against most types of substrate.
  • ICYNENE MD-C-200 rejects bulk water; ICYNENE LD-C-50 has <5% water absorption.
  • Holds its strength when exposed to water.
  • Not easily damaged.
  • Not a source of food for mold or pests.
