What Is Closed Cell Foam Insulation?

Closed cell spray foam insulation is one of the most effective and energy-efficient insulation options available on the market today. Boasting a high Thermal Value, it is the perfect insulator in terms of thermal conversion for both commercial properties and residential homes.

Without a doubt, closed cell foam insulation is a go-to product if you are looking for energy efficiency, structural integrity, water resistance, and it has many other advantages besides. The sheer density of the closed cells enables it to insulate your property to an incredibly high standard – much more so than traditional insulation materials like polyethylene fibres, polyester, or foil.

Looking at the material in more detail, closed cell foam insulation has the following properties (see below):

How does closed cell insulation work?

Closed-Cell Insulation Properties

Icon

Closed Cell Foam Density

Closed cell foam insulation has an extremely dense cellular composition.

Icon

Water Impermeability

This cellular composition also prevents water from passing through it, making it an effective solution for moisture and damp problems.

Icon

Thermal Value

Closed cell foam insulation has a far better Thermal Value per cm than other type of insulation, providing superior temperature regulation for your property.

Icon

Moisture

Closed cell foam prevents moisture growth due to its water-impervious composition, which effectively increases your property’s lifespan.

Icon

Currents

This type of insulation can effectively reduce convective currents in walls and roofs.

Icon

Quality of Air

The air quality in your property dramatically improves with closed cell insulation, because its close density can block out any toxins, dust, and the prevent the growth of mould and moisture.

Areas of Application for Closed Cell Foam Insulation

Spray foam closed cell insulation is both durable and sustainable, making it the ideal insulation solution for commercial properties. Since it is more robust in nature than its open-cell insulation counterpart, it is better suited for:

• Metal Buildings

• Commercial Properties

• Pole Barns

• Basements and Crawl Spaces

• Application in Exterior Areas

Closed Cell and Open Cell Spray Foam Insulation Comparison

Both types of spray foam insulation are highly effective for use in building designs (including designs for industrial properties) and will offer consistent performance and energy efficiency.

When applied to the exterior of a building, closed cell spray foam insulation provides performance advantages that differ from those offered by open-cell spray foam when used on a property’s interior.

  • Adds wall racking strength and impact resistance.
  • Is ideal for continuous insulation.
  • Can be applied at very low temperatures.
  • Has lower vapour permeance.
  • Rejects bulk water (making it ideal for use in flood zones).
  • Higher tensile and bond strength.
  • Higher Thermal Value per cm (making it convenient to apply in narrow spaces).

FREQUENTLY ASKED QUESTIONS

  • Is closed cell foam insulation waterproof?

    Arrow
  • Generally, Eco Spray closed cell foam insulation is water-resistant, and the high-density variants are waterproof. In contrast, open-cell foam insulation is neither 100% waterproof nor water-resistant.
  • How strong is closed cell foam?

    Arrow
  • When applied to a substrate, closed cell foam insulation expands to about 35 to 50 times its original volume to form a rigid insulation with a compressive strength of between 15 and 25 psi.

    This makes Eco Spray Foam’s closed cell foam perfect for enhancing the racking strength of most wall and ceiling assemblies.
  • Does closed cell foam block sound?

    Arrow
  • Compared to open-cell foam, closed cell foam has a much higher Thermal Value. As a result, closed cell insulation forms a dense foam protection that can absorb low-frequency noise more effectively.
  • Does closed cell foam need a vapour barrier?

    Arrow
  • A separate vapour retarder is often not necessary since Icynene spray foam is already highly effective at minimising air leaks. The majority of Eco Spray Foam insulation options officially qualify as a Class II vapour retarder that complies with your commercial building code requirements.
  • How many centimetres of closed cell foam do I need?

    Arrow
  • The recommended thickness for spray foam closed cell solutions depends on the build of your property and its useage. Please feel free to speak to one of the team at Eco Spray Foam to discuss your requirements.

Advantages Of Spray Foam Insulation

Compared to other types of insulation, spray foam is quick to apply and is versatile in the sense that it can be applied to walls, floors, and attic spaces alike. Due to its robust nature, it will protect your home even under adverse weather conditions. It also doesn’t require any mechanical fixings and is available in various types.

Why do you need closed cell insulation

The Essentials Of Spray Foam Insulation

Spray foam is a two-part liquid insulation material that insulates and creates an air seal wherever it is applied. It has a lot of immediate and long-term benefits that contribute to its rapid growth in popularity in building construction.

The two part liquid is made up of an iso and a resin, which are kept separate until applied at the site, where they are combined to create an incompressible foam.

Spray Foam: Closed Cell Or Open-Cell?

The suspended bubbles shield in open-cell foam is slightly more susceptible to moisture vapour than its closed cell equivalent, because it is thinner.

Closed cell insulation spray foam has a similar composition, but the bubbles are filled with an insulating gas, making it denser.

Both types of foam insulation increase the energy efficiency of your property. The main difference is that open-cell is cheaper to install, as closed cell foam density offers a higher level of insulation and protection.

Despite its relative ease of use, the installation of spray foam pressed insulation is still best left to expert technicians. Contact us for a free inspection today!
