What are the advantages of using open-cell spray foam insulation?

Typically, buildings expand and contract due to temperature differentials, moisture content, wind load and seismic etc. Closed-cell insulation cannot accommodate the movement of the building. Open-cell spray foam insulation provides air sealing benefits in many applications at lower cost Vapor permeability supports bi-directional drying of assemblies – critical in warm climate zones/seasons Flexibility allows it to expand and contract with any movement of the building structure ensuring long term air sealing Water-blown product maintains a lower GWP (GWP 1) than most closed cell products .

How is Icynene Spray Foam installed?

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. The solution can be safely sprayed directly onto electrical and plumbing. For renovation projects, Icynene’s 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.

What is Spray Foam Insulation?

Spray foam insulation is a type of insulation that can be used in the roof space at either the joist or rafter level, to help keep warm air in the home during the winter and also prevent the home getting too warm in the summer.

Typically, the spray foam is made up of polyurethane. It is sprayed as a liquid, which then gradually expands to up to 100 times its original volume, and once set it not only creates an effective insulating layer, it also acts to reduce noise pollution.

Features of Closed Cell Spray Foam

This spray foam sets rock hard – it is not compressible when it has set, this means that it can help support the structure of the property, however if installed incorrectly it can exert unnecessary strain on the structure of the home. This type of foam will also tend to be much denser as a result and this also means it will be heavier.

The insulating properties of closed cell spray foam tend to be greater than the open cell spray foam, partly because they can put bubbles of insulating gas in the foam (not just air) which helps slow the movement of heat across the foam.

The typical u-value for closed cell spray foam is about 0.16 W/m2K

The final thing about closed cell spray foam is that it will not allow moisture across it, which means that you will need to consider ventilation in the loft space to prevent build up of condensation.

Features of Open Cell Spray foam

Open cell spray foam is less dense than close cell spray foam, so it will not help strengthen the structure of the building. In addition, its chemical make-up means that it doesn’t offer the same level of insulating effectiveness as the closed cell. However on the plus side it has high vapour permeability allowing it to breath far better than the closed cell spray, so condensation build up should be less of an issue. The other major benefit is that it offers better acoustic insulation, absorbing more sound in normal noise frequency ranges.

Since spray foam has better insulating properties than wool (when the same thickness is used), you can achieve the same u-value by insulating to a much lower depth. This means that if space is an issue (remember you need to install 270mm of wool insulation to meet building regulations now), then spray foam could be the answer – typically you will require a depth of 150mm to achieve a u-value of 0.16 W/m2K, but a depth of just 40mm will help you to achieve a u-value of 0.40 W/m2K.

What is Icynene medium density spray foam?

ICYNENE MD-R-210™ id the latest medium density spray foam that utilizes innovation in order to improve building performance and minimize environmental impact.
This rigid foam is suitable in areas where space is limited and is ideal where the foam will be left exposed such as workshops, Industrial and commercial buildings, all farm buildings including potato and grain stores for thermal insulation and condensation control.

Key Standard Benefits vs. Light Density Spray Foam Insulation:
> Lower U-value per 25 mm
> Higher compressive strength
> Higher tensile strength
> Lower vapour permeance

ICYNENE MD-R-210 can be applied on a variety of substrates under a range of temperature and humidity conditions.
> Contains up to 12.6% recycled plastic in the MD-R-210 resin, 100% water blown, no blowing agent
> A Low-Emitting Material (LEM) as per CHPS EQ 2.2 Section 01350 (Collaborative for High Performance Schools).
