150mm Kingspan Thermawall TW55 PIR Insulation Board

150mm Thermawall TW55 is an insulation solution designed to enhance the thermal performance of timber frame and steel frame walls. With a low thermal conductivity of 0.022 W/mK, Thermawall TW55 delivers high-performance insulation. These 150mm insulation boards are simple to cut and handle, resulting in a smooth installation process. Moreover, they are available in various thicknesses to meet diverse insulation requirements.

The product highlights of this insulation solution include being amongst the more thermally efficient cavity wall insulation products, suitable for use with both timber frame and steel frame wall constructions, and being able to be used between studs or as an insulating sheathing, making it ideal for Modern Methods of Construction (MMC).

Here are some "Applications":

The 150mm insulation solution can be applied in various ways, such as being used as insulated sheathing on timber frame or steel frame, insulation between studs on timber frame walls, external masonry with timber frame, or ventilated cladding with timber frame.The insulation solution can be applied in various ways, such as being used as insulated sheathing on timber frame or steel frame, insulation between studs on timber frame walls, external masonry with timber frame, or ventilated cladding with timber frame.

The Facings

During the manufacturing process, Kingspan 150mm PIR is bonded with a low emissivity composite foil on both sides, which serves as a reflective surface to enhance the thermal resistance of any unventilated cavity next to the board.

The Core

150mm Kingspan Thermawall TW55's core is made using Nilflam® technology, which is a top-quality fiber-free rigid thermoset polyisocyanurate (PIR) insulant. The manufacturing process uses a blowing agent with zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP).

Compressive Strength

When tested to BS EN 826:2013 (Thermal insulating products for building applications. Determination of compression behavior), 150mm Kingspan PIR insulation usually surpasses a compressive strength of 150 kPa at 10% compression.

Water vapour resistance

When tested in accordance with BS EN 12086:2013 (Thermal insulating products for building applications. Determination of water vapor transmission properties), the product typically attains a resistance well above 100 MNs/g.

Durability

The longevity of 150mm TW55 is reliant on proper installation, supporting structure, and usage conditions. With correct installation, it can potentially have an unlimited lifespan.

Fire performance

150mm Kingspan Insulation TW55 has an F Euroclass rating under System 4 AVCP. When utilized in pitched roof constructions and placed under a suitable roof covering, it can fulfill national criteria for external fire exposure.
