Skin contact: May cause sensitisation and tingling/irritation of the skin.

Eye contact: May irritate eye tissue. 

Ingestion: May cause irritation, nausea, vomiting and diarrhoea.

Inhalation: Dry/sore throat. Coughing. Irritation of the respiratory tract. Irritation of the nasal mucous membranes. Runny nose.

LATER: Possible inflammation of the respiratory tract. Risk of lung oedema. Respiratory difficulties.

Expanding foam is a versatile material predominantly employed for filling gaps and sealing cavities in various construction and renovation projects. Its primary functions include enhancing thermal insulation, effectively reducing drafts, and improving overall energy efficiency in buildings. Additionally, expanding foam serves to dampen sound and prevent moisture ingress, making it a crucial component in noise reduction and building protection.

Common applications of expanding foam include sealing joints and gaps around windows and doors, insulating plumbing pipes, and providing thermal insulation in walls, attics, and crawl spaces. By creating an airtight seal, the foam minimises the infiltration of outside air, thereby enhancing the building's energy performance and comfort levels.

One of the key benefits of expanding foam is its ability to fill irregular gaps and voids, ensuring comprehensive coverage that traditional insulation methods may not achieve. This capability enables the foam to serve as both a structural reinforcement and an insulating barrier, thereby preventing heat loss during colder months and reducing unnecessary energy consumption.

Moreover, expanding foam significantly contributes to acoustic insulation by filling spaces where sound can travel, thus minimizing noise transmission from external sources. This feature is particularly valuable in urban environments where noise pollution can be a significant issue.

Additionally, expanding foam plays a crucial role in moisture management. Sealing gaps effectively helps to prevent water infiltration, protecting the integrity of the building structure from potential water damage, mould growth, and other moisture-related problems.
