What Are the Benefits of Pir Insulation?

High Thermal Efficiency: PIR insulation has a lower thermal conductivity compared to many other types of insulation. This means it can achieve the same level of insulation with less material, helping to keep buildings warmer in winter and cooler in summer, thereby reducing energy costs. Fire Resistance: PIR insulation offers enhanced fire performance characteristics compared to some other foam insulation materials. It tends to char rather than ignite, which helps to slow the spread of flames in case of a fire. Moisture Resistance: PIR boards are highly resistant to moisture absorption, which helps to prevent the insulation's thermal performance from degrading over time. This moisture resistance also contributes to the overall durability of the insulation, making it a long-lasting choice. Ease of Installation: Due to its lightweight nature and the availability of large panel sizes, PIR insulation is relatively easy to handle and install. It can be cut to fit various spaces, making it suitable for floors, walls, and roofs. Environmental Impact: Many PIR insulation products have a low Global Warming Potential (GWP) and zero Ozone Depletion Potential (ODP), making them a more environmentally friendly choice than some alternatives. Versatility: PIR insulation can be used in a variety of applications, including residential, commercial, and industrial buildings. It is suitable for new constructions and retrofit projects alike, offering flexibility in use for floors, walls, roofs, and cavity insulation. Compatibility with Other Materials: PIR insulation is compatible with various building materials and systems, including plasterboard, roofing membranes, and most types of cladding. This makes it a versatile option for comprehensive building insulation solutions. Cost-Effectiveness: While the upfront cost might be higher than some other insulation materials, the superior thermal performance of PIR insulation means that the overall energy savings over the life of the building can be significant, making it a cost-effective choice in the long term.

What thickness is needed for pir insulation?

For effective insulation in the UK, the choice of PIR (polyisocyanurate) insulation thickness depends on the part of the building you are insulating and the desired thermal performance, as measured by U-values. U-values represent the rate of heat transfer through a material; lower values indicate better insulation performance. Wall Insulation: To insulate walls efficiently, a thickness range of 50-130mm of PIR insulation is commonly utilized. Specifically, to achieve an optimal U-value of 0.17 W/m²K, which indicates a high level of insulation and energy efficiency, a thickness of 125mm of PIR insulation board is recommended. This thickness is ideal for minimizing heat loss through walls, ensuring the building retains heat more effectively and remains energy efficient. Roof Insulation: For roofing, a thicker insulation layer is often necessary due to roofs being a significant point of heat loss in buildings. A thickness of 150-200mm of PIR insulation is typically used to reach the recommended U-value of 0.16 W/m²K. This level of thickness helps in significantly reducing heat escape through the roof, contributing to a warmer interior during colder months and aiding in energy conservation. These recommendations serve as a guideline for achieving efficient thermal insulation in buildings, contributing to better energy savings and comfort. It's important to note that specific insulation requirements can vary based on building design, location, and current building regulations.

Info

Mannok Therm Cavity / MC PIR insulation is a high performance, fibre free board, with a rigid thermoset insulation core and faced on both sides with a low emissivity composite foil facing.

The low emissivity foil facings increases the thermal resistance of the residual cavity and reducing the overall U-value of the wall.

The good dimensional tolerances of the Mannok Therm Cavity / MC PIR insulation board enabling it to be tightly butted to form a continuous layer of insulation.
