Aircraft Factory

The existing factory roof needed to be waterproofed and an increase in the energy efficiency of the building was also desirable. This would be achieved by applying a solar reflective coating to reduce the cooling costs of the factory. Because of its location in the south of Spain, the cooling costs had been quite high due to the air conditioning being used nearly six months per year.

The building had also been suffering from water ingress, which was causing problems internally. Therefore the customer wanted a durable yet cost-effective waterproofing solution for the building’s roof, which could be spray-applied and provide effective water-tightness.

Sikalastic®-560 was specified for the project, which is a cold-applied, one-component waterborne liquid-applied membrane that cures to provide guaranteed waterproof protection. The product is highly elastic, UV-resistant and can be spray-applied, allowing large areas to be coated in a short amount of time. Sikalastic®-560 was specified in white because of its reflective properties, which would help reduce the building’s cooling costs in this hot climate.

Sikalastic®-560 is a versatile, ready to use liquid membrane, which can be applied directly onto a variety of different substrates and different geometries, with no need to install any additional substrate component (unlike the bituminous sheet solution). It can be easily applied in both new construction and roof repair projects, allowing the extension of the lifetime of existing roofs. It is also available in light colors, like the white Sikalastic®-560 used in this project, and has a Solar Reflective Index (SRI) of 102, which can enhance energy efficiency by reducing significantly cooling costs over time.
