External walls: PhotonCheck-A1 is an advanced membrane suitable for use in various external wall types, including timber frame, metal stud, and concrete constructions. It is specifically designed for buildings where enhanced fire safety is critical, such as residential blocks of flats, student accommodations, care homes, sheltered housing, hospitals, and dormitories in boarding schools. Its Euroclass A1 non-combustible fire rating makes it an ideal choice for high-risk residential buildings (HRRB) and structures with a storey above 18 metres in height. PhotonCheck-A1 provides reliable fire protection while maintaining thermal efficiency and moisture control, ensuring both safety and comfort in demanding environments.

How is PhotonCheck installed?

PhotonCheck is typically installed over insulation layers or directly onto structural elements such as walls and roofs. It is fixed using staples, nails, or adhesive, and all joints and overlaps are sealed with compatible tape to ensure an airtight and vapor-tight seal. Installation should follow the manufacturer’s guidelines to achieve optimal performance.

How does PhotonCheck contribute to energy efficiency?

By acting as an effective vapor control layer, PhotonCheck minimises air leaks and controls moisture movement. This helps maintain consistent indoor temperatures and reduces the load on heating and cooling systems, leading to lower energy consumption and cost savings.

Can PhotonCheck be used with other insulation products?

Yes, PhotonCheck can be used alongside a variety of insulation products to enhance the building envelope’s thermal and moisture performance. It complements other insulation materials by adding an additional layer of moisture control and air tightness.
