Width : 1 &#; 1.25 m.
Thicknesses : 25 &#; 200 mm.
Polyisocyanurate (PIR) and Polyurethane (PUR) Sandwich Panels shares almost the same insulation characteristics, the main difference between them are as follow:
In general PIR and PUR rigid foam have almost similar chemical base and same insulating properties, they are produced by mixing several components in the metering machine or foam machine, the chemistry formulation of Polyisocyanurate (PIR) is primarily based on Methylene Diphenyl Di-isocyanate (MDI), these properties are also known as isocyanate, ISO or POLY (Polyethylene Glycol (PEG) and Polyester Polyol). However, PIR sandwich panels have a higher ratio of physical properties than Polyurethane (PU/PUR), this can dramatically improves the performance characteristics and fire behavior of PIR sandwich panels, and for example the ratio of isocyanate used for PIR foam is approximately 100:150, whereas Polyurethane (PU/PUR) contains only 100:110.
Polyiso rigid foam have great flame resistance characteristics over Polyurethane (PU), thanks to its rigid imide ring structures which slows the spread of flames and creates less smoke when burnt, on the other hand PIR Foam have higher fire performance than PU foam. PIR sandwich panels are normally classified as Class B1: Flame Retardant and have higher working temperature, while PU foam is normally produced as Class B2 (Normal Flammability building material). Hence, compared to PUR foam, PIR foam is more fire resistant and safer than PUR foam.
Polyisocyanurate (PIR) foam has superior closed cell structure (normally 97%) and hydrophobic nature, this offer them 0.9% water absorption, this rate is considered higher than Polyurethane (PUR) foam which have closed-cell structure, but their water absorption is normally below 2%, and thus, PIR sandwich panels have low water absorption and low permeability to moisture.
Rigid Polyiso foam (PIR) are dimensionally stable than Polyurethane (PUR), thanks to its excellent mechanical strength and cross-linked structure which offer exceptional stability to ageing, and high resistance to moisture and fire temperatures ranging from -200°C to +120°C, while, PUR can resist temperatures between -150°C and +80°C.
PUR sandwich panels
PIR insulated sandwich panels can be used under elevated temperature ranging from -40°C to 80°C (from -40°F up to 176°F), thanks to its temperature resistance properties of polyisocyanurate foams which are obtained using products of citric acid condensation.
PIR sandwich panels are completely resistant to moisture, thanks to their non-capillary & non-absorbent features which made them highly resistant to the overgrowth of mold, fungi, termites&#; infestation, and vermin, whereas, their biologically stable properties and waterproof facing enable them to withstand extreme weather conditions.
One of the most important challenges facing the construction industry is the lifetime energy-efficiency of buildings, PIR sandwich panels are mainly designed to reduce the costs of heating and cooling for up to 50%, while they deliver great thermal performance, and ensure minimal thermal bridging through excellent air tightness and continuous insulation, hence they can contribute to LEED rating system and positively participate in zero-energy building standards.
Energy saving PIR sandwich panel
PIR sandwich panels are designed and manufactured in conformance with the EN - which specifies the requirements for factory made, self-supporting, double skin metal faced insulating sandwich panels. Furthermore, PIR sandwich panels should comply with the highest standards, whilst all components require rigorous testing and should carry a CE mark which confirms that all materials, labeling, and packaging meet the requirements of EU regulation.
Yes, PIR sandwich panels are eco-friendly building materials, they are made from the most sustainable and innovative polyisocyanurate foam (PIR) which are CFC, HCFC, and HFC free, on the meanwhile, they are 100% recyclable, reusable, and have a very low Global Warming potential. In addition to that, their great thermal insulation can ensure energy-efficient surfaces, and thereby saves heating, ventilation, air conditioning and maintenance cost.
Eco-friendly PIR sandwich panels
Polyisocyanurate (PIR) sandwich panels can last for over 70 years, they are mainly designed to provide high-performance building envelope that can last for decades without maintenance, thanks to their highly durable insulation that guarantee stable thermal resistance, while all material used doesn&#;t degrade over time.
