What is Celotex's Fire Classification?

Celotex PIR Insulation Boards are tested to BS EN 13501-1 with a classification of E. Simply put, this means they are combustible and will contribute to the spread of fire. Because of this, the boards must not be used in the external facades of buildings over 18m in height in England and Wales or over 11m in height in Scotland. When using Celotex - or any other type of insulation - it's important to ensure your installation meets all relevant national Building Regulations and guidance and local, national and other applicable standards relevant to your construction or application.

Are Celotex Insulation Boards Waterproof?

Celotex PIR is a closed-cell, moisture-resistant insulation board, meaning it does not hold water or retain water. Whilst this attribute helps it to prevent water ingress - especially in the wall cavity where this can be a persistent problem - it does not mean that Celotex insulation boards are suitable for external use. Celotex insulation boards should only be installed inside the building structure, and not on an external facade or inverted roof.

Are Celotex Insulation Boards Sustainable?

Celotex insulation is manufactured from polyisocyanurate foam, a type of plastic that comes with an environmental toll. The creation of these types of plastics involves immense energy and resources—and can result in the emission of greenhouse gases and other hazardous pollutants. Additionally, the disposal of Celotex insulation board can be a concern if it is not properly recycled or disposed of in a responsible manner. If it ends up in a landfill, it can take hundreds of years to decompose, contributing to environmental pollution and waste. That being said, Celotex does provide some sustainable benefits. Its insulation properties can help reduce energy consumption in buildings, which can lead to lower greenhouse gas emissions and energy bills. Celotex also claims to use recycled materials in its production process, reducing the amount of virgin materials needed. In essence, while Celotex may have some environmentally friendly aspects, it is critical to evaluate the entire product's ecological footprint and investigate other potential sustainable insulation options.
