Icynene Addresses Thermal Comfort and Condensation Concerns on Pig Farms
A key player in the Irish pork industry, Kiernan Pig Farms embarked on a major refurbishment project that saw Icynene spray foam insulation address thermal comfort and condensation concerns.
As part of their on-going development and growth, Kiernan Pig Farms, one of Ireland’s largest pork suppliers, launched a major refurbishment project across a number of their piggery sites to improve thermal comfort and address condensation control.
Critical factors for successful pig production and animal husbandry are optimal animal comfort, health, growth and productivity. Barns and sheds must be able to maintain steady indoor temperatures to achieve these factors.
To ensure that their facilities were able to provide steady thermal comfort as well as address condensation concerns, Kiernan Pig Farms asked local Irish licensed Icynene contractor, Airseal Insulations, to provide a cost- effective, high-performance solution.
Icynene in Agricultural Facilities
With a number of the shed roofs requiring minor repairs and being too expensive to replace completely, Airseal Insulations recommended that Icynene Classic Plus, a low- density open cell spray foam insulation product, be used to seal the underside of the roof structure.
As an open-cell spray foam, Icynene Classic Plus was chosen over closed- cell spray foam alternatives due to its ability to expand and contract with the natural movement of the roof. Additionally, the insulation material would allow the roof timber to breathe naturally while its air seal capabilities would block out allergens and pollutants from entering the space.
With nine stages of work to be completed in total, Airseal Insulations completed the rst stage of the project over a two week period, covering approximately 2,200m2 (23,680 sq. ft.) of roof space with 75mm (3”) of Icynene Classic Plus spray foam insulation.
It is estimated that the inclusion of Icynene spray foam insulation into the pig farms will reduce energy loss by up to 48%.
Technitherm® successfully insulates cavities in a building in a severe exposure area subject to flooding
Bank of Ireland
The bank is situated next to an industrial estate where the road in to the estate is one and a half metres above the ground level of the bank.
During the winter snow storms, the snow drifted against the side wall of the bank, and this was added to as more piles of snow from the roads being cleared were put against the side wall.
As the snow melted, the melt waters soaked through the outer brick leaf of the side wall and into the cavity. This was exacerbated by the wind driven rain against the wall and resulted in the cavity flooding and the water soaking through the inner leaf of the cavity, causing severe dampness on the inner walls of the bank.
The problem was to dry out the walls, find a flood resilient material which would also insulate the cavity to a high standard. There was also concern that the flooded cavity might have structurally weakened the wall.
To dry out the walls, some outer leaf bricks were removed from the side wall and rubble in the cavity was cleaned out to a depth of 300mm and the bricks were replaced.
Technitherm was then installed into the cavity as flood resilient cavity wall insulation. Being closed cell insulation Technitherm has been independently tested to prove its flood resilience, so Technitherm was able to prevent further ingress of water and solve any structural problems caused by the flood waters.
The walls of the Bank are now flood resilient, removing any further danger of dampness on the inner walls. Technitherm has also provided insulation values which match Building regulations and eliminated any structural problems caused by flooding.
Engineering pull‐test on Technitherm® injected cavity wall
The Test – Step 1
An unstable cavity wall was injected with Technitherm®. All the wall ties were isolated from the outer leaf, and then a chase cut through the bricks and mortar to the foam to create a 1m² free standing, brick panel.
The Test – Step 2
A sturdy steel frame was then added to the panel, and connected to a load cell. Once connected, the panel was subjected to increasing pull‐forces from the load cell, under the supervision of the specialist engineer in charge of the test.
At 1.818 tonnes/m², with no adhesion failure at all, the test was aborted to prevent any damage to the inner leaf. Technitherm® is, therefore, proven to provide a simple and highly effective solution to cavity wall failure, whilst insulating buildings to Building Regulation Standard BS 7457:1994 (BBA Cert No. 97/3426), with zero ozone depletion potential (ODP). A low GWP version is also available.
Technitherm: Homeowners in flood risk areas
Flood waters can penetrate cavity walls and cause major damage to the outer wall, the cavity wall ties, any fibrous insulation, the inner wall and decor. 3 million houses are at risk.
Technitherm®, a water resistant, closed cell cavity insulant:
- Prevents corrosion of wall ties
- Prevents insulation damage
- Replaces wall ties where they are already in disrepair
Technitherm® is shown to be the best performing type of cavity wall product according to a recent report on Flood Protection issued by DEFRA, DCLG and The Environment Agency. The report states that cavity wall insulation should be rigid closed cell materials, as these retain their physical integrity and have low moisture take up when exposed to flood waters.

A Traditionally Built Cottage
A traditionally built cottage consisting of two “leaves” of random stone with a variable width cavity. The outer leaves were buckling due to inadequate tying and foundation movement, and the energy efficiency of the cottage was very poor, as conventional wall insulation could not be installed for a number of reasons. Foundation repairs could not be undertaken due to the danger of the walls collapsing during the work. Pressure grouting and partial demolition were considered unacceptable due to instability and cost, and neither measure would improve the energy efficiency of the cottage.
Technitherm® was injected into the cavity to stabilise and insulate the walls so that underpinning could be carried out, followed by local rebuilding of the buckled panels. The injection was carried out over 3 days to minimise disruption of the random stone outer leaf. Such was the success of the Technitherm® installation that not a single stone was displaced and the process was completed with the owner in occupation.
After treatment with Technitherm® the walls were so stable that it was unnecessary to undertake any further structural repairs. Joints in the outer stone leaf were simply raked free of old mortar and re‐pointed. The cost was less than 1/6th of other accepted repair techniques. The cottage was weatherproofed due to Technitherm® being hydrophobic closed cell PUR.
Technitherm® enhanced the insulation of the walls and draught‐proofed the cottage in the single installation, and now the owner is enjoying warmer living conditions and lower energy bills. The structural repair was completed leaving the wall virtually unblemished.

Icynene Insulation selected for Eircom Projects
The Icynene Insulation System has been selected as the preferred insulation of choice for Eircom’s office facilities throughout Ireland.
Eircom is Ireland’s principal provider of fixed-line telecommunications services with 2.6 million fixed lines and its mobile division has over 1million customers. The first project, insulating Eircom’s 700 sq meter facilities at Castlebar, has recently been completed by Icynene Contractor Airseal Insulations Galway.
With the focus firmly on reducing energy demand, Icynene’s soft foam insulation was applied to the underside of the roof structure at Castlebar and the process reduced heat loss through the roof by 83 per cent and the overall building heat loss by 48 per cent. Air leakage and air infiltration was also reduced by 93 per cent.
“Eircom were experiencing very high energy bills and occupant discomfort at this facility which was cold in winter and excessively hot during the summer months,” said GMS Insulations Ltd managing director Gerry Sheridan who is the importers and distributors of The Icynene Insulation System to Ireland and the UK. “Using Icynene’s water blown soft foam insulation, which gives off no harmful emissions, we could offer dramatic energy savings, better indoor air quality and ensure reductions in CO2 emissions.”
It was Eircom who made the initial approach to GMS as they were looking to improve the energy efficiency and insulation standards across a number of their commercial buildings and offices.
“We carried out demonstrations for Eircom and they also came to see Icynene being installed at other projects we were working on,” said Gerry Sheridan. “Soft foam is the fastest growing insulation material in the world today and Eircom were impressed as it is a one application product, is not labour intensive and is applied on site.“
“The Icynene Insulation System was installed efficiently in a number of Eircom buildings without disruption to service or personnel and proved to be a cost effective method of maintaining and even improving comfort levels” said an Eircom spokesperson
Founded in Canada in 1986, Icynene’s unique formulation has won awards around the world as extremely environmentally friendly foam for superior indoor air quality, energy savings and the reduction of CO2 emissions in sustainable buildings. It has been used in over 300,000 projects including offices, private homes, hospitals, museums and art galleries and also in acoustic projects.
