Energy efficiency and improved thermal insulation are no doubt the pillars of sustainable construction in modern times. With the increasing focus on reducing carbon footprint and meeting energy efficiency targets, companies with ties to this field are constantly searching for innovative solutions that can meet and exceed industry standards.
While some may argue that traditional insulation materials such as mineral wool and expanded polystyrene (EPS) are still sufficient for most applications, they’re not as effective as newer alternatives taking over the scene. Perhaps the most prominent of these is PIR insulation, which offers superior thermal performance in comparison to other materials, thanks to its general low thermal conductivity and density.
Is 60mm PIR Enough?
The panel’s exact thickness varies from product to product, but most manufacturers recommend a minimum thickness of 60mm for PIR insulation to achieve the desired thermal performance. The thicker the panel, the better the heat resistance but that doesn’t necessarily mean that anything less than this number is insufficient.
Many industry professionals argue that it’s not just the thickness, but the quality of installation and the overall building design that ultimately determine the effectiveness of the panels themselves. With that said, installing resilient and highly efficient 60 mm PIR insulation does require a certain level of expertise and knowledge. When applied correctly, this thickness can deliver remarkable results and contribute significantly to the overall energy efficiency of a building.
What Kinds of PIR Insulation Are There?
While all of them have the same basic structure, different manufacturers have developed their versions of this kind of insulation. At the heart of each one is a rigid foam core that’s been chemically treated to enhance its thermal properties, along with a thin reflective foil layer on one or both sides. This means they can easily be cut to any shape or size required and have a wide range of applications.
Ecotherm
Being at the forefront of innovation and energy efficiency, Ecotherm prioritises PIR insulation’s eco-friendliness in its production process. Their panels use a blowing agent with zero ozone depletion potential (ODP) and low global warming potential (GWP), both of which are significant environmental factors to consider when choosing insulation materials.
These two practices resulted in the brand’s Eco-Versal range of insulation panels, specifically designed to help meet current and future energy efficiency targets. Each panel combines advanced fibre-free rigid polyisocyanurate (PIR) insulation with a strong, puncture-resistant foil facing on both sides for added durability and performance. As such, you can use them in a variety of applications, including pitched roofs, flat roofs, and walls.
Kingspan
As far as producing ever-improving PIR insulation products goes, Kingspan is a brand that needs no introduction. Their Kooltherm range of panels is a testament to the company’s dedication to innovation and sustainability. With an industry-leading thermal conductivity of just 0.018 W/mK, its insulation material delivers exceptional performance in terms of both thermal efficiency and fire resistance.
One of its most significant advantages remains its compressive strength, which inherently improves durability and the panels’ ability to withstand harsh weather conditions. Moreover, thanks to its closed-cell structure that prevents moisture ingress, Kooltherm insulation is easy to handle during installation and maintenance. Its remarkable thermal properties and reliable moisture protection bring an unparalleled level of performance and safety to every project.
Mannok
Next up is Mannok, a brand that’s focused on delivering ultimate thermal efficiency and sustainability while providing a wide range of insulation solutions. Their PIR insulation panels offer exceptional performance with an impressive thermal conductivity of 0.023 W/mK and are readily available in various thicknesses.
Unlike other manufacturers, Mannok’s PIR insulation panels are an entirely non-toxic product, with no CFCs or HCFCs used during production. This aspect, combined with the brand’s strict quality control and high production standards, offers greater peace of mind to both contractors and building owners.
Additionally, their panels contain no added phenol-formaldehyde (PF) resins that can sometimes compromise the natural sustainability of other materials. This particular material has been linked to adverse health effects in some instances, which is why Mannok has eliminated it from their PIR insulation’s production process. As a result, their panels are more than suitable for use in residential and commercial construction projects, with minimal environmental impact.
Xtratherm
Finally, Xtratherm is a brand renowned for providing innovative and high-performance PIR insulation solutions that meet the strictest energy efficiency standards. Their Tritherm range of panels is highly versatile, offering an easy-to-install thermal solution for roofs, walls, and floors in both new and existing buildings.
Their advanced manufacturing techniques involve bonding two layers of polyisocyanurate insulation with a foil facing to create a triple-layer insulated panel. This process results in a product that offers superior thermal performance and durability, with an A+ Green Guide rating. When coupled with the brand’s full technical support and extensive range of insulation products, Xtratherm’s Tritherm panels are ideal for any construction project looking to improve energy efficiency while reducing environmental impact.
How Do You Install PIR Insulation?
Installing 60 mm PIR insulation is a straightforward process, but it does require proper planning and preparation to ensure optimum performance. You can either cut the panels to size using a sharp knife or saw, or use pre-cut panels if they are available. Once you have the correct measurements, simply slot them into place between the studs or joists in your building’s structure.
It’s essential to seal any gaps between the panels using tape or adhesive to ensure a tight fit and minimize thermal bridging. When there’s any overlap between panels, make sure to seal the joints with insulation tape or adhesive as well. Additionally, make sure to leave some space around pipes and electrical outlets to avoid compressing the insulation and compromising its thermal performance.
Once installed, PIR insulation requires minimal maintenance and should last for the lifetime of the building. However, regular inspections are necessary to ensure no damage or wear and tear could affect its performance. Look out for any signs of moisture or mould, as these can indicate a problem with the insulation’s protective foil layer.
