Suntean & SolaRoof technology

Insulation

Super efficient insulation with U-value >0.025 depending on thickness with a minimum of 50cm depth of soap bubbles that creates a temperature buffer towards the outside keeping the heat either in or out. This soap bubble protecting can be filled or removed from the cavity in minutes for rapid respons to needs, weather, seasons and climate; either manually, with simple timers or fully automated.

Bubbles does not provide a static insulating, but enable a stable temperature in the building envelope by generating bubbles from room temperate soap liquid. Bubble renewal is required to maintain the required insulation value. Correct bubble replacement in each renewal cycle is therefore key! Bubble last up to 8-9 hours in the sealed cavity and can be sucked out or replaced by new room temperate bubbles.

Shading

Reduce the light by 50-70% simulating light cloud cover without blocking the solar radiation.

There is no need for large storage of soap liquid as this expands 500-1000 times by bubble generators to fill the cavity. However, the benefits of connecting this to a larger thermal mass is significant and advisable whenever possible.

Heat collection

The building envelope acts as a solar collector, harnessing solar energy with or without bubbles.

Thermal mass storage

Liquid thermal mass stored in the ground or within the building for optimal energy balance.

Cooling and humidity control

Circulating cool water prevents overheating and dehumidifies the space, eliminating the need for ventilation.

Algae production

Incorporates a three-layer system to produce algae, enhancing sustainability by adding another level of production for feed, food, materials or renewable energy in form of biogass or biofuel.

Materials

SolaRoof is not bound to any specific choice of materials.
