Insulate With Easy Foam

Enjoy the benefits of insulating with Icynene, creating an environment that is Healthier, Quieter, More Energy Efficient.

If you are constructing a new food premises or refurbishing your existing food premises, you will need to contact your local council or health department to ensure you comply with design and fit out requirements, before commencing any construction or refurbishment. You may be required to comply with the Australian Standard for the Design, construction and fit-out of food premises (AS 4674-2004). This Standard provides criteria on design and construction to assist with compliance with Standard 3.2.3 for new food premises and alterations to existing food premises.

Solid Wall Construction

Food Safety Standards 3.2.3

Process:
When Electrical and Plumbing rough-ins are complete, Gib or FC sheeting is glued and screwed on then THIS is the ideal time for us to do our application.
Screws will be visible for us to identify the studs, noggins will then need to be identified before we can start.
Each cavity will receive a 10-12mm drill hole half way up from bottom plate and one directly below noggin, both placed roughly in the centre.
Same applies to the upper wall section, one half way up and the other just below the top plate.
This is repeated for all walls in the scope of works.
Spray Foam is injected in the 2 stages from bottom to top to ensure all voids/cavities are full to prevent access from cockroaches and weevils etc.
Now complete, your guys can stop the entire wall to either sand, paint or Tile prior to kitchen equipment being installed.

IMPORTANT NOTE:

To enable cost effective and hassle free installation, this process needs to be done before the installation of: Tiles, splash backs, benches and sinks, kitchen equipment and s/steel sheeting.
All wall sheeting to be glued and screwed for reinforcement strengthening. If you intend to sheet walls in thinner grade materials, please ensure you attach extra screws particularly around edges and joins.

Certificate of Compliance

On completion and payment of job, a certificate of Compliance will be issued for you and your Certifier.

Cavity Wall Insulation (Existing void wall cavities)

  • Masonry cavity wall
  • Timber frame wall lining
  • Timber frame wall sheathing
  • Steel stud frame walls
  • Besser block cavity fill
  • Double brick cavity fill

Common problems with traditional wall insulation:

  • Minimal control of air leakage
  • Some types are damaged by water and moisture, this will compromise their performance
  • Insulation damaged during installation
  • Insulation damaged during construction by other tradesmen
  • Joints and various shapes are difficult and time consuming to insulate
  • Human error can occur
  • Often requires fixings to get the insulation to stay in place
  • Damaged by pests
  • Unwanted noise will still penetrate the building
  • Pollutants pass through the gaps in the wall
  • Moisture transfer through the building structure
  • Sags over time or becomes displaced
  • Condensation and mould causes by moisture transfer

Why icynene has the advantage for wall insulation:

  • Increased energy efficiency
  • Improved indoor air quality
  • Provides sound insulation
  • Icynene expands 100 times its original volume to fill all the gaps
  • No food source for mould or rodents

Why moisture management is so important

As moisture travels around your building in the warm moist air, it will leave during the air leakage process. As the air passes through gaps and traditional insulation material it will eventually reach the external cold surface where it will condense. This condensation will provide a home for mould growth and make dampness will occur than can later lead to the damage of the structure.

Icynene acts as an air and moisture barrier and will protect against the transfer of moisture, this will protect against condensation and mould issues.

Double Brick Cavity Walls

Insulating Cavity Walls

Roof Insulation

Roof insulation is traditionally made up of either fiberglass or foam boards. These styles of insulation can result in many issues for the owner and lead to energy loss. Here are some typical examples of these issues.

Installation time can be excessive and often involve a large crew, lots of preparation is required and securing the insulation can be awkward.
Traditional insulation will often move with time and sag, become dislodged and break the thermal efficiency of the product.
Awkward angles, shapes and design features often make it hard to truly insulate the roof area efficiently.
Human error can take place and a lot of wastage of the product can occur.

Icynene benefits for roof insulation:

Icynene can be installed far quicker than traditional methods so down time is reduced, access hire costs reduced and man labour hours saved when using Icynene.
Icynene will not loose its shape over time, this means no sagging or creating potential air leakage areas within the building.
As Icynene expands up to 100 times its original volume it will fill all gaps, crevices and unseen areas that traditional insulation cannot cover.

Insulating Steel Roofs

Pros and Cons of Steel Buildings

Metal Framing is Less Energy Efficient than Wood

Compared to wood, steel is not a good insulating material; it actually conducts cold and heat. It is necessary to use additional insulation in exterior walls. Metal promotes condensation and over time will lead to drywall damage and discoloration if not addressed. In order to prevent condensation exterior walls require a moisture barrier beneath the drywall. Additional insulation and installing the vapour barrier add to the overall expense of choosing metal framing over wood.

Steel Framed Structure Insulation

Often steel framed structures are great users of energy, this is due to all the thermal bridging across the structure between the inside and outside. Condensation will often occur on the steel structure is the temperature of the material is below the due point.

Icynene provides the ability to break the thermal bridging and when applied to the steel structure it will not allow the warm moist air to touch the material below the due point, thus condensation not forming.

Icynene will provide:

  • Increased energy efficiency
  • Improved comfort within the building
  • Prevention of condensation forming, frost forming and mould occurring
Airtight Solution

Dew Point Explained

Dew point is the temperature at which a dew will start to occur, this temperature is always colder than the current temperature. The dew point is effected by the moisture content of the air and the surface temperature of the materials it can come in to contact with. As the current temperature changes the dew point will follow. We can work out what level of insulation is required to stop this occurring by using a condensation risk analysis. This will be supplied along with a U-Value calculation before application takes place.

Cold Floor

Concrete floor slab insulation

Icynene's medium density spray foam insulation can be used to insulate below slab grade on your concrete floor. It can help provide a seamless thermal layer of insulate and won't be damaged during installation unlike traditional rigid insulation boards.

Often damage can occur to traditional boards by:

  • Rebar cages and the concrete slab construction
  • Insulation often sags of cracks when installed on uneven substrates
  • Edges and trimmed parts will often compromise the traditional insulation and not provide you what it states on paper

Benefits of using Icynene for Floor insulation

  • Easily insulates edge work and uneven surface
  • Totally seamless so no compromising of thermal performance
  • Rejects bulk water
  • Holds its strength if exposed to water
  • Not easily damaged
  • High compressive strength
  • Takes the shape of the substrate (i.e., gravel, uneven concrete)
  • Provide a continuous air barrier
