LambdaBoard, which is a type of insulation board made from rigid polyurethane foam. Here are some of its properties:

1.    Thermal Insulation: LambdaBoard has excellent thermal insulation properties, with a thermal conductivity (lambda value) of around 0.022-0.024 W/mK. This means that it can effectively reduce heat transfer and help to maintain a comfortable indoor temperature.

2.    Moisture Resistance: LambdaBoard has a closed-cell structure, which makes it resistant to moisture and water vapor. This property helps to prevent the accumulation of moisture within the building envelope, which can lead to mold growth and other issues.

3.    Strength and Durability: LambdaBoard is a lightweight but strong and durable material. It can withstand compression and has a high compressive strength, making it suitable for use in a range of construction applications.

4.    Fire Resistance: LambdaBoard is a fire-resistant material and has a low flammability rating. It is classified as a Class B1 building material, which is the second-highest fire rating available.

5.    Chemical Resistance: LambdaBoard is resistant to many chemicals, including acids and alkalis. This makes it suitable for use in environments where chemical exposure is a concern.

6.    Easy to Install: LambdaBoard is easy to cut and shape, which makes it simple to install in a variety of applications. It is typically installed using mechanical fasteners or adhesives.

Overall, LambdaBoard is a high-performance insulation material that offers excellent thermal insulation, moisture resistance, strength, and durability. It is a versatile material that can be used in a wide range of construction applications, from roofs and walls to floors and foundations. 

About Lambdaboard

LAMBDABOARD is a flexible faced Polyisocyanurate (PIR) insulation board made on a continuous laminator. The polyisocyanurate cored insulation uses a hydrocarbon-based blowing agent which has zero Ozone Depletion Potential (ODP) and complies with Kyoto Protocol regarding Global Warming Potential (GWP). LAMBDABOARD insulation is the answer to HCFC and HFC free insulation.
