Where to use

Flat Roofs: Foamglas S3 Slab is ideal for flat roofs, including trafficable roofs, due to its high compressive strength and durability. It can support the weight of foot traffic, equipment, and even vehicular loads without deforming. Additionally, its closed-cell structure makes it impervious to water and vapour, preventing moisture ingress and ensuring long-term thermal performance. This makes it particularly suitable for use in roofs where durability and resistance to weathering are critical.
Floors: In flooring applications, Foamglas S3 Slab provides excellent thermal insulation while also offering high compressive strength to withstand loads from foot traffic and furnishings. Its moisture-resistant properties protect against dampness and potential water damage, making it an effective insulation layer for both ground floors and upper levels. The material’s dimensional stability ensures that it maintains its performance over time, even under constant use.
Foundation Slabs: Foamglas S3 Slab is also highly effective for insulating foundation slabs. Its resistance to water absorption and vapour permeability ensures that the insulation remains dry and maintains its insulating properties, even in contact with the ground. This helps to prevent thermal bridging and reduces the risk of frost heave in colder climates. Its compressive strength provides a stable base for the building structure, supporting the weight of the building without compression or degradation.

In all these applications, Foamglas S3 Slab contributes to energy efficiency by providing consistent thermal insulation, protecting against moisture, and maintaining structural integrity.
