Guidance on Selection

Choosing the right insulation board from the 120mm category revolves around identifying the specific needs of your project. Here are some general guidelines:

Application Area: Identify whether the insulation is for walls, floors, or roofs as some products are specialised for specific applications.

Thermal Conductivity: Consider boards with lower thermal conductivity for enhanced insulation.

Compressive Strength: For areas like floors that may bear loads, select boards with higher compressive strength.

Fire Resistance: Depending on your project’s safety requirements, choose boards with appropriate fire-resistant properties.

Environmental Conditions: For external applications, opt for boards that can withstand environmental stress like Kingspan’s Thermaroof series.
