We test our living rooms to validate their waterproofing. The first test is done in the laboratory under 200 L/m²/h of water for 3 hours, which is equivalent to a tropical shower of 200 mm per hour. The second test is done in the field under real-life conditions by our teams. This living room is fitted with a polyurethane-coated polyester flysheet measuring 2,000 mm. It also has seams that have been waterproofed with heat-sealed strips, and a 140 g/sqm polyethylene groundsheet.
