Icynene Open Cell and Closed Cell Insulation

Icynene Open Cell and Closed Cell Insulation

Icynene Open cell insulation and closed cell insulation are the two main types of spray foam insulation. The terms refer to the chemical makeup of the insulation material which are both very commonly found in most modern building applications, but not always applicable to both. So what's the essential difference between them? We have the answers and we're here to share them with you in the following article...

Benefits of Icynene Open Cell Insulation

Icynene’s (and our) most popular spray foam insulation is Icynene H2 Foam Lite, better known as LD-C-50. It has been used extensively across North America before being used across Europe, obtaining a number of approval certificates along the way.

Open cell insulation us light, flexible and adheres to a breathable membrane situated in-between your roof and the Icynene. BBA accreditation which means that it is acceptable for new domestic homes in England and we are the only approved Icynene BBA installers in the country.

Open cell insulation is usually cheaper than closed cell but it is important to have your building surveyed before application as certain types are suitable for certain properties. Choosing the wrong type of spray foam insulation could end up costing your money in the future.

Open cell installation is very similar to closed cell, but it has different effects. Open cell foams expand to 100x their size once applied allowing them to be installed in hard to reach areas that traditional insulations might miss.

Icynene Open Cell Spray Foam Interior Applications

  • Can be installed at a significantly lower cost and target the same specified R-value*
  • Can achieve greater R-value* if not restricted by space
  • Lower raw material/resource use
  • Permits bi-directional drying
  • Will accommodate long-term creep and seasonal movement
  • Hydrophobic material
  • Air barrier and insulating material

Icynene Open Cell and Closed Cell Insulation

In order to maintain their higher than normal levels of insulation they must be strong and dense. This densely achieves a reinforcement to building, making them stronger but can also cause damage as your property moves with the season so be sure to have a Licensed Icynene Contractor evaluate your property before installation!

Benefits of Closed Cell Insulation

Closed cell foam are understandably denser than their counterpart with the capability to insulate air, preventing draughts in your home and keeping a regulated temperature to add to comfort. Closed cell insulation also cuts down on humidity, but it does not however, allow moisture to be breathed through it which makes it more beneficial for industrial properties where damp protection is not a requirement.

Closed-cell Spray Foam Exterior Applications

  • Can be applied at very low temperatures (as low as 5oF)
  • Adds wall racking strength as well as impact resistance
  • Ideal for continuous insulation solutions
  • Higher R-value* per inch – easier to accommodate high R-value* requirements in narrow spaces
  • Lower vapor permeance (can be a Class II VDR)
  • Can reject bulk water
  • Higher tensile and bond strength

Open Cell Spray Foam Insulation

R stands for resistance to heat flow. The greater the R value the more insulation the material provides. There are many different factors to consider when chose a R value including climate you live in, building regs, the amount of insulation already in your home and your energy usage. Make sure you consult with an Icynene approved dealer before committing to purchase

IN A NUTSHELL: Spray Foam Summary

Closed Cell Foams, with their dense and structurally supporting makeup, are generally suited for commercial and industrial properties.  They are also suitable for situations where moisture exclusion is a requirement.

Icynene Open cell is suitable for domestic installations. It’s soft and spongelike texture absorbs and extracts water from your home and their light chemical make-up means that they will not damage the structure of your property.
