Why we do it better?

Insulation Properties
PIR has the highest insulation values of any insulation product, due to the low heat- conductibility of its independent bubble formation. PIR is 50% more thermally efficient than the Polystyrene (EPS) core found in other New Zealand manufactured insulated panels e.g. Bondor. This superb thermal performance allows buildings to achieve premium levels of energy efficiency, with some of the thinnest possible solutions. PIR is also completely stable and does not suffer from expansion or contraction.

With fire performance being an important selection consideration for many projects, The Roofing Store PIR board is the perfect choice. Unlike EPS, PIR has a class 1 fire rating and will self- extinguish as soon as the cause of the fire is removed. PIR insulation is manufactured through an irreversible chemical reaction, which means it cannot melt.

Acoustic Performance

PIR has a high sound-absorption value. Transference of sound is kept to a minimum, giving the ability to both contain and block noise.

Environmental Benefits
PIR Insulation panel contains no CFC’s or HCFC’s which are harmful to the environment. The environmental impact of insulation materials is independently rated. Materials are rated on an A+ to E scale, where an A+ rating is given to materials with the lowest environmental impact. PIR insulation is generically rated A, providing a lower environmental impact than extruded polystyrene and some cellulose glass solutions.

PIR’s superior insulation qualities also mean a significant reduction in the energy costs of both heating and cooling.

PIR board is non-deleterious, meaning that materials used during production (as well as in the end product itself) contain no compounds harmful to the environment. The products do not emit noxious fumes or damaging gases and are safe to handle. On a large scale, PIR reduces carbon dioxide emission and extensively contributes to the saving of fossil fuels, helping in the fight against global warming. It takes 5kg of oil to produce one square metre of 40mm thick PIR wall insulation. But over a 50-year building life, this insulation will save 230kg of heating oil, repaying its original cost by a factor of 46. These excellent results put PIR insulation at the top of the leader board when it comes to potential energy savings.

Moisture Resistance
Water absorption through exposure to moisture or indeed in exceptional circumstances through floods, is a significant factor with any modern insulation product. Due to having a closed cell structure, PIR is a hydrophobic product meaning it does not absorb water. This allows the thermal performance and integrity of the product to be retained regardless of water exposure.

Life Expectancy
As PIR does not sag, absorb moisture or be permeated by air, you can be confident of consistent performance which will last the full lifetime of the building.

Testing & Research
In a recent study comparing the cost benefits of using various insulation products, PIR foam (Polyiso) insulation emerged as the decisive winner over extruded and expanded polystyrene insulations. The study (completed by Energy Conservation Management, an independent energy research and analysis firm in the USA) revealed pertinent information about factors such as return on investment, installation costs and payback rates, which determine the cost effectiveness of using different insulation products in construction applications. The bottom-line numbers showed why PIR foam has become the leading insulation product in the marketplace today, as well as why it is the preferred choice for specifiers, architects, and contractors worldwide.
