Insulation industry news from Global Insulation

US: Johns Manville has launched Cavity-Shield, a formaldehyde-free fibreglass batt insulation product intended for use in the concealed spaces of multifamily buildings. The National Fire Protection Association-approved product is being marketed as an alternative solution to sprinklers in the interstitial space. The batts are designed to serve as a passive fire solution for limiting potential flame spread between and through floors. It is also intended to reduce construction costs by reducing the time and resources required for installers to complete the job.

Germany: Dennert Poraver has developed an insulating render formulation by using Poraver expanded glass aerogel granules from Cabot in 0.01 - 4mm sizes. The expanded glass granules producer says that aerogel thermal insulation renders are ultra-light, water-repellent, open to diffusion and achieve high thermal insulation even with small layer thicknesses.

The new product is targeted for the interior and exterior renovation of historic buildings. Due to the thin application layer, the producer says that the characteristics of the building remain largely unchanged. The building material can also be used for rendering masonry in new buildings. The insulating renders are also classified as ‘non-combustible, smoke-development free, non dripping.’ This means that they can also be used for facades, where previously only mineral wool-based insulating materials could be used due to increased fire protection requirements.

Poraver and Aerogel were combined for the development of a mineral thermal insulation render in order to combine the advantages of both lightweight aggregates. Cabot Aerogel supplied aerogel in the form of 0.01 - 4mm granules for the insulation render. Poraver was added to the render as a mineral aggregate with a grain size of 1 - 2mm. Various proportions of aerogel and Poraver were tested. After the tests, it could be determined that the compressive strength and processing properties had improved ‘significantly’ with the addition of Poraver. The most economical and practicable formulation has a thermal conductivity of 0.037W/mK with a dry bulk density of 199 kg/m³.

US: Owens Corning has been recognised by the Environmental Leader Product & Project Awards for three of its insulation products. EcoTouch Insulation, Thermafiber RainBarrier Continuous Insulation and Unbonded Loosefill Insulation have each been independently certified as made with renewable energy and reduced embodied carbon as part of the award scheme.

These products were available for specification and purchase in late 2017. Owens Corning worked with SCS Global Services to develop guidelines for the certification, since no such certification previously existed.

“A building represents two kinds of energy use: ongoing energy to operate the building and embodied energy in the manufacture of the building products. Insulation reduces the operational energy needed for the building. Owens Corning’s new insulation products reduce the embodied carbon inherent in the building as well,” said Jesus Hernandez-Torres, senior Research and Development leader at Owens Corning.

US: Kingspan has launched its QuadCore insulation panel products in North America at the AIA Conference on Architecture in New York. The insulated metal panel products use a hybrid insulation core with a closed microcell structure. Initially, Kingspan will offer QuadCore in its KS Shadowline, KS Micro-Rib and Optimo panels, and QuadCore will eventually be available in all Kingspan insulated metal panels.

Italy: Ursa has launched a new extruded polystyrene (XPS) panel product called Ursa Maior. The insulation producer says that the product, Ursa Maior S27P, is the first and only extruded polystyrene thermal insulation panel that combines a thermal conductivity rate of 0.027W/mK with high compressive strength of 300kPa. Other features include water resistance and resilience to freeze and thaw cycles. It is being produced at Ursa’s Bondeno plant.

Australia: Kingspan Insulation Australia’s Kooltherm K10 Soffit Board FM product has been accredited by FM Approvals. The closed cell phenolic insulation has been accredited with Class 4880 for ceiling applications.

To achieve the FM accreditation, Kingspan’s Kooltherm K10 product was installed in a ceiling for a full scale burn test (UBC 26-3) and set alight. During the test, temperatures, smoke levels and flame spread are all monitored. A burning wood crib was set alight in the corner of the room and left to burn for 15 minutes. During this time, in order to pass the test, the spread of the flame must not exceed the area of the installed K10 test panel.

FM Approvals offers third party testing and certification services including fire tests.

UK: Celotex has found errors in a safety test for its RS5000 polyisocyanurate foam (PIR) insulation board product that was used as part of the rainscreen cladding system in the refurbishment of Grenfell Tower. As part of a review of the product the company has determined that there were differences between the system as tested for BS 8414:2 and the description of that system in the report of the test. The BS 8414:2 safety test was originally conducted prior to the RS5000 product being launched.

The insulation producer is exploring whether any safety issues arise from the differences in the test. It says it has notified the relevant bodies and is contacting its customers.

“It is a matter of real regret for us that this issue has arisen: we fully recognise its potential seriousness and that it will give rise to concern. We are working hard to arrange the further testing as quickly as possible and we will make a further announcement once the results of that testing are available,” said Celotex in a statement.

Celotex suspended supply of RS5000 PIR insulation board in June 2017 following a fire at Grenfell Tower in London that killed 71 people.

UAE: Kingspan Insulation has started producing its Thermaroof TR22 brand insulation product at its plant in Dubai, according to the Emirates News Agency. The product has a fibre-free polyisocyanurate (PIR) insulation core. It is used for flat roofing cover boards to overlay new and existing flat roofs waterproofed with single-ply and cold liquid applied waterproofing. The plant also produces other products in the flat roof insulation line.

US: Kingspan Insulation has expanded its GreenGuard extruded polystyrene (XPS) insulation board range with additional thickness products and strengths. The range now includes 3 inches and 4 inches in select 25, 40 and 60 psi compressive strength boards, and a new four-sided routed drainage channel board. The new products are intended to extend the GreenGuard line into roofing, cold storage, and various below grade and vertical wall applications markets.

Canada: Icynene has launched two new light density spray foam insulation products: Icynene Classic Ultra and Icynene Classic Ultra Select. A key feature for the new products is the elimination the requirement to paddle mix by hand prior to application with the introduction of an expanding blade mixer. The insulation producer also says that the new products offer significantly better cohesion than existing Icynene open-cell spray foam insulation products. The foams can also be sprayed at drum temperatures from 15℃ for Icynene Classic Ultra and from 20℃ for Icynene Classic Ultra Select

“The introduction of Icynene Classic Ultra and Icynene Classic Ultra Select demonstrates our commitment to delivering customer-valued innovation in the insulation category. Sprayers no longer need to paddle mix the resin material or wait for the liquid to warm up, so they can quickly start spraying these two high quality, high yielding products,” said Mark Sarvary, president of Icynene.
