What is a PIR board and why do you need it? We’ll answer these questions in this article. Learn what it is, what makes it effective, and what it costs. Then, make an informed decision when insulating your home or building. Listed below are some benefits of PIR insulation boards. You’ll also learn about the benefits of Polyisocyanurate and its thermal conductivity. After reading this article, you’ll have a better idea of whether you need a PIR board or a regular insulation board.
Insulation board
When you’re looking for an insulation board for PIR, you’ve probably heard of Celotex PIRB. Designed to meet general insulation, fire resistance, and sound reduction needs, this product provides excellent fire protection and is ideal for underfloor applications. Besides being easy to manipulate and install, it is also very durable. This high-quality product can reduce your heating and cooling bills and improve the aesthetics of your home.
A common question for a contractor is, “How can I determine which PIR material is the best for me?” The construction industry uses specific terms and descriptions to describe products. Some people may misunderstand these terms, or misapply them. For instance, “PUR” stands for polyisocyanurate, which is a thermally efficient material composed of long, complex chains of hydrocarbons. A PUR index of 100 is generally considered ideal for PIR insulation board.
Insulation board for PIR is made of a rigid core sandwiched between two layers of high-performance aluminium facings. The core of the board is made of polyisocyanurate, which is a thermoset plastic. This material’s high thermal resistance makes it a good choice for thermal insulation in both new and old buildings. It also offers excellent compressive strength. The board is easy to fit, and is available in various thicknesses.
PIR insulation boards come in many sizes. Smaller-format PIR products are often called batts, and are typically made from stone or glass mineral wool. Larger-format PIR insulation boards are typically 2.4m by 1.2m, and can be laid in a staggered pattern or split into smaller boards to form a row. A board can be installed directly against the ground. There are other considerations.
Polyisocyanurate
The thermal resistance of a Polyisocyanurate PIR board is determined by measuring its average water vapor permeability. The permeability value is the ratio of the vapor-to-solid water content. PIR boards have different equilibrium moisture content values when compared to a similar board made from the same material, but the same construction process. Hence, they are both effective and efficient for preventing heat loss.
One of the most popular brands of premium quality PIR insulation boards is EcoTherm. It manufactures several boards depending on the application such as Eco-Versal, Eco-Torch, and Eco-Cavity. As a result of the effectiveness of PIR, it is used by a lot of manufacturers. EcoTherm’s products are all made of fibre-free rigid polyisocyanurate PIR board with low lambda values.
Polyisocyanurate is a thermoset polymeric material made by reacting isocyanates with polyols. The chemical reaction creates a tough, robust material. Unlike thermoplastic materials, which soften on heating, PIRs remain tacky when cold. Polyisocyanurate PIR board is made from a rigid PIR core that is bonded with low emissivity foil. The low emissivity foil is a key element of the polyisocyanurate PIR board. This material can be incorporated into ceilings, walls, and other structures.
In this study, three different types of PIR insulation were tested to determine how they perform hygrothermal properties in various climates. The three types of PIR insulation studied in the study included a fiberglass facer, an aluminum facer, and unfaced PIR. For the purpose of comparison, the PIR board made with an aluminum facer was found to perform better than its counterparts with fiberglass facers.
Thermal conductivity
Generally, the thermal conductivity of PIR boards is high. However, these properties are not fully understood in practice. This study aimed to improve understanding of this property by determining how the material behaves under real-world conditions in a building envelope. A detailed research was conducted to answer these questions. This paper is a preliminary report of the findings of this study. Further research will be needed to fully understand this material’s thermal conductivity.
A study was conducted to determine the thermal resistance of PIR boards. The study also characterized the hygrothermal properties of PIR boards and its impact on building energy efficiency. The results showed that the thermal resistance of PIR boards was higher than that of conventional insulation. It is also regarded as having a lower permeance. However, this study is limited to older buildings. Therefore, thermal resistance and hygrothermal properties of PIR boards should be measured and documented in buildings.
Generally, PIR is produced as foam and is used as rigid thermal insulation. The thermal conductivity of PIR boards is 0.023 W/mK and 0.16 BTU/hr*ft2*degF. In addition, PIR foam panels are laminated with pure embossed aluminium foil. This type of insulation is also used for pre-insulated duct. Corrugated steel facings are used extensively to produce prefabricated PIR sandwich panels. They are widely used in vertical walls and roofing.
In order to determine the hygrothermal performance of PIR insulation, it is important to measure the water vapor permeability of the material. For this purpose, a water immersion test is performed. The results of this study were presented in Table 5.
Cost
The main advantage of PIR thermal insulation board is that it provides the highest level of heat insulation. However, it is also expensive and bulky, so it must be cut to size before installation. It can be measured from the outside or cut inside the suspended floor. Typically, the PIR board is faced with aluminium foil for thermal and vapour control. It is then fixed in place using battens or plastic friction fit supports.
There are three main types of PIR insulation materials. Each one of them provides different degrees of heat insulation. Generally, they can be used for a number of applications, including roofing, walls, and floors. However, it’s best to consider the cost of the material first, before determining whether it’s worth the expense. Celotex offers several types of PIR insulation board, including celotex GA4000.
PIR insulation board is made with a polyurethane core sandwiched between two layers of aluminium foil. It is available in different thicknesses, from 12mm to 150mm, and eliminates thermal bridges. The PIR board is lightweight and easily cut. It is ideal for applications like insulated sheathing on timber frames, external masonry, and ventilated cladding. PIR board is also highly resistant to air infiltration and water vapour, making it ideal for new builds and retrofits.
Extruded polystyrene, or Styrofoam, is another popular rigid board insulation material. It costs $0.45 per square foot and has a high R-value per inch. Depending on the thickness, EPS can be as thick as four inches, and can cost $1.60 to $2.40 per square foot. It is best to have a professional do the installation. This way, the installation is done correctly and there will be no problems later.
Installation
Thermano thermal insulation is a highly effective thermal insulator that will provide substantial savings on heating bills. It is durable and will provide a peace of mind for several generations. PIR boards are also very hard wearing and are similar in strength to bricks and concrete. They do not absorb moisture and do not attract animals. However, proper installation is essential to ensure maximum performance. Listed below are some helpful tips on how to install PIR board.
Installing a PIR board is relatively easy. Before beginning, make sure the surface is completely clean. Then, apply a layer of plasterboard or other insulating material. Then, install it to your desired depth. The PIR board is easy to install, as it has a grid pattern that makes it easy to lay. It is important to keep the installation site clean to avoid contamination from dust and debris. In general, you can install two or three layers of PIR board at a time.
