Why should you consider specifying spray foam insulation? – Eco Spray-Foam Systems Ltd

Everyday more architects are specifying spray foam insulation for their projects and there is a multitude of reasons for this. With product shortages and costs skyrocketing across the insulation market, in addition to spray foams other benefits it is now the most cost-effective solution in a variety of scenarios. In addition to the cost element there are an array of reasons to specify spray foam -:

• BBA & KIWA approved product & installers
• Allows for design freedom
• Air tightness guaranteed – Ideal for sealing the envelope in passive house construction
• Class 0 fire rated available
• Eco friendly – 100% water blown with no chemical blowing agents HFC’s or PBED’s (Open-Cell)
• Global warming potential of 1
• Ozone depletion potential of 0
• Condensation Control
• Asbestos encapsulation
• Rapid installation – Circa 150 m2 installed in a day

Structure

A spray insulation is referred to as open or closed cell because of the difference between the small bubbles (cells) that make up the foam.

Open cell – The cell composition of this component is not completely encapsulated, allowing for a flexible and versatile spray foam insulation.

Closed cell – Take a more rigid format, cells are completed closed and encapsulated to provide robust and rigid properties whilst locking out any forms of moisture and humidity.

Expansion

Open cell spray foam insulation expands a monumental amount from just 1 mm thick of liquid application the foam will expand to 100 mm – This is how the foam can effectively cover hard to reach areas traditional cannot.

Closed cell spray foam is made up of small tightly compressed bubbles which minimizes the amount of air seeping into the bubbles allowing expansion of about 25 mm. This can be applied in multiple layers to achieve a higher thermal value.

Unique benefits

Open cell is often used as a form of acoustic/sound insulation, mainly in drywall and in between levels. It is particularly good at eliminated airborne sounds such as TV/Radio or talking in adjacent rooms.

Due to the closed cell insulation high density structure, it can add structural integrity to the area in which it is applied. If a wall or roof is coming towards the end of its expected lifetime you could consider insulating with closed cell spray foam to extend the life of the wall or roof.
