Answers to some of your Frequently Asked Questions

Icynene spray foam insulation is an insulation and air barrier material that seals walls, floors and ceiling cavities against air movement, including spaces around electrical outlets and light fixtures and where walls meet windows and doors. Icynene spray foam insulation can provide an effective air barrier insulation to minimize air infiltration through walls and ceilings, preventing drafts, cold spots and energy loss.

Icynene can maintain its installed U-values throughout its service life, contrary to air permeable insulation types that lose their thermal performance over time due to the deterioration in the insulation quality (compromised &/or shrinking) and ongoing convective current loops within the insulation (up to 50% heat loss).

Icynene spray foam insulation products are installed by extensively training and licensed Icynene® contractors only.

JHJ Insulations is an approved Icynene Contractor and has been operating throughout Scotland for over 5 Years.

In Europe, Icynene spray foam insulation have been assessed by the British Board of Agrément, KIWA, ATec: Avis Technique, the EEA: European Economic Area and the VTT: European Technical Approval.

For builders, Icynene spray foam insulation can reduce construction time by simplifying the insulation process and minimising the number of callbacks due to building envelope failure. Using Icynene spray foam insulation, heating and cooling costs are typically reduced by up to 50% and smaller, less expensive heating and cooling equipment can be used because of the reduced heating and cooling loads.

For homeowners, Icynene spray foam insulation offers the opportunity of lower heating and cooling costs from reduced air infiltration and a more comfortable home, draft free without cold spots. Furthermore, Icynene’s continuous air barrier capability will significantly reduce unwanted airborne noise from the outside resulting in a quieter interior living space. Proper mechanical ventilation must be provided to Icynene insulated houses and when merged with a Mechanical Heat Recovery System, superior air quality can be achieved for a healthier indoor environment.

Icynene open-cell spray foam products do not contain environmentally harmful blowing agents like HFCs, HCFCs or HFAs, in fact most Icynene spray foam insulation products are 100% water-blown making them better for the environment. Organic chemical compounds from petroleum extract are the main source of its ingredients.

Icynene foam insulation is installed by fully trained, licensed Icynene contractors who spray the solution into open building envelope such as studded walls, ceilings and floors.

For renovation projects, Icynene LD-CP-50 pour foam solution is used. This product is simply injected into small holes drilled into plaster or gypsum faced walls, or from the outside of the wall, whichever provides the easiest access to the cavities.

In each case a fully trained, licensed Icynene contractor must install the product. Icynene foam insulation products are not Do-It-Yourself (DIY) products.

Spray foam expands up to 100 times its original volume within 4-10 seconds. Independent studies indicate that with 24 hours’ active ventilation after spraying is completed, Icynene spray foam insulation is completely cured.

No. However, water can work its way through the foam under pressure or by gravity force. When the foam is placed on water it will float and upon removal it will not contain any water and it does not lose any of its insulating properties. But, if it is immersed under water, water can be forced into the foam by the hydrostatic pressure; however, once it is removed from water and allowed to dry out, the original insulating properties will return.

Icynene’s open-cell spray foam insulation products are vapor permeable to allow water vapor molecules to flow through the foam. This means any moisture in the building’s concrete or timber can escape through the insulation as the building dries out, thus eliminating moisture that could cause rot or mould.

No. Icynene spray foam products are chemically inert meaning they will not change chemically or physically over time.

Icynene spray foams are considered to be environmentally preferred products due to their air sealing qualities which contribute to improved indoor air quality, reductions in energy consumption as well as greenhouse gas emissions. Icynene does not contain ozone depleting gases and do not contain environmentally harmful blowing agents.

Icynene LDC-50 requires more oxygen to burn than there is in the atmosphere; it will ignite, but is self-extinguishing. Complete details of the Flame Index and Smoke Index of all Icynene spray foam insulation products can be found in each product’s Technical Data Sheet. Harmful flame retardants such as PBDE’s (poly-brominated diphenyl ethers) are not contained in Icynene’s formulations.

No. Icynene spray foam insulation has been extensively tested and found to be safe. It has been safely applied over electrical wiring, as well as plumbing runs, for more than twenty-five years.

No. Icynene spray foam insulation is non-corrosive. This has been confirmed by extensive testing undertaken on behalf of Icynene.

Icynene spray foam insulation products do not offer any food value, therefore do not support bacterial or fungal growth. Furthermore, it also does not retain water, making it an unappealing environment for fungal spores.

Icynene spray foam insulation offers no food value to rodents or pests. It should be noted that it would not present a barrier to their entry if they decided to gnaw through it, so Icynene spray foam should not be considered a barrier to rodents or pests.

As an effective air-seal, Icynene’s range of open-cell, light-density spray foam eliminates the air gaps through which airborne sound travels. As a result, these spray foams are able to noticeably control mid-range frequencies noise such as voices and traffic. Icynene open-cell, light-density spray foam thereby adds to the acoustic property of the building envelope.

Icynene insulates and air-seals to control unwanted random air leakage – which traditional cellulose and fiberglass insulation can’t do without the use of extra sealing materials. Traditional insulations can also leave gaps and seams around electrical boxes or light fixtures (compromising performance), but Icynene fits perfectly around all detailing for a complete air-seal. 

Icynene seals tiny cracks and penetrations that would otherwise allow unwanted airborne irritants to invade the living space. Home occupants are protected from outdoor allergens, pollutants, and humidity. Icynene makes it easy to get a tight fit around wall openings, such as windows, electrical/cable service entry points, and light fixtures.

Icynene’s 100% water-blown light density spray foam makes it an even healthier option for homeowners. Icynene is recommended for spaces occupied by people with allergies, asthma and other particular respiratory issues. 

There are no blowing agents such as CFC’s (chlorofluorocarbons) or HCFC’s (Hydrochlorofluorocarbons) in Icynene’s light density products. Spray foam insulation is produced by mixing 2 components at a high temperature, which causes the water content to evaporate during installation. This process creates an odour and requires venting. As soon as the foam “cures” (or sets), which occurs within seconds, it no longer produces the odour. It usually takes about 24 hours for the odour to completely disappear, although spaces will be habitable within 4 hours.

Build tight and ventilate right. With the proper use of exhaust fans and heat/energy recovery ventilators, a building envelope can be made tight while clean, healthy air is circulated through the structure. Air leakage needs to be controlled in houses by making wall and attic assemblies as tight as possible. This not only prevents drafts but reduces the amount of airborne noise and dust from entering the building while ensuring that insulated cavities remain moisture-free. In existing buildings natural ventilation is normally sufficient, along with any existing mechanical ventilation in areas of high humidity.

Why Choose Icynene

The Icynene Spray Foam Insulation System is a series of soft, flexible spray foam insulation products that delivers up to 50% greater energy savings when compared to other home insulation products. Icynene is the only foam on the market to have achieved BBA, ETA and IAB certifications.

Did you know that up to 40% of your home’s air, whether heated or cooled, can be lost via air leakage? Your heating system or air conditioner can end up working harder to make up for the air that is escaping your home, which can drive up your monthly heating and cooling bills. Icynene spray foam insulation can help by eliminating air leakage as well as addressing conductive heat loss.

Reduce noise – Icynene open-cell spray foam can help reduce sound from noisy indoor rooms such as media rooms and laundry rooms, outdoor noises such as traffic and playgrounds, and transferred noise such as flushing toilets.

Buildings insulated with Icynene can achieve extremely high levels of airtightness without the need for air barriers, tapes or sealants – saving time and money. Spray foam helps achieve building compliance assuring clients and contractors peace of mind, and a lifetime of high performance.

Minimising the flow of random airborne moisture entering your home helps protect against mould growth that can lead to conditions such as asthma and allergies which can cause symptoms such as itchy eyes, sneezing, and coughing. Most of the moisture that enters the walls of your home is carried in the air.

Architects have to be aware of the limits housing materials impose; laying sheets of fiberglass and rolls of foil or rigid board insulation can determine the shapes and angles a floor plan can use. Icynene spray foam, on the other hand, moulds itself to all kinds of shapes allowing for alternative and unique design layouts.
