Why Hapri Insulation?

Hapri Polyiso, or polyisocyanurate, is a closed-cell rigid foam board insulation. It’s used mostly on roofs and walls of offices, industrial buildings, warehouses, retail and manufacturing facilities, and large buildings. It has a great reputation as a high thermal performing insulation and is also unique for solving some of the more complex air leakage and insulation challenges in existing homes. Here are a few of the reasons why we recommend using Hapri Polyiso insulation for our clients:


Hapri PUR/PIR rigid foam board has the best thermal resistance (R-value) of any building insulation product in the market, meaning the product is extremely efficient. This is great news for builders since it reduces the amount of material needed to achieve the same effects as other types of insulation


Hapri PUR/PIR cost effectiveness is one of the greatest benefits of using this product for your next project. Increasing the thickness of polyiso on a roof deck significantly reduced energy costs for the building. The ongoing savings on monthly energy bills means the cost of installation can be paid off and justified by the significant monthly savings.


Compressive strength is a material’s ability to maintain its shape and to resist deformation when under a heavy weight or force. Hapri PUR/PIR insulation boards perform very well in compression testing, and are available in a range of compressive strengths. This is important since the material is used for wall application, which requires the product to support flexible siding materials. When used for roofing, the boards must be able to support the weight of anyone installing or repairing the roof, support fastener loads, and sustain the total roofing system. Having high-quality insulation with high compressive strength is important for the durability and longevity of any building.


When measuring a material’s impact on the environment, organizations like the DCL, DM, and Estidama don’t just measure energy saving impact. They also evaluate the effects the manufacturing process has on the environment and the impacts the material has on the environment while in use. Hapri PUIR/PIR perform extremely well on all environmental testing. During manufacturing, polyiso insulation uses a hydrocarbon-based blowing agent which has zero Ozone Depletion Potential (ODP) and virtually no Global Warming Potential (GWP)


All construction materials, including polyiso insulation, must pass extensive fire safety testing. Among all foam plastics Hapri PUR/PIR has one of the highest levels of inherent fire resistance due to its strong chemical structure. In addition, polyiso can be ordered with a thermal barrier and left exposed to living areas to meet code. This makes the material more fire resistant and reduces the spread of flame. Whether you are a homeowner or a builder working on a large-scale industrial project or a complex home retrofit, consider using polyiso insulation. As an alternative insulation material, it provides superior R-value, fire resistance and a host of other benefits.
