PRODUCT DESCRIPTION

COOL-R is a liquid applied, highly reflective waterproofing membrane with SRI 107, that reduces roof temperature by nearly 70%, with a concurrent decrease of internal temperature of up to 10°C. The basic and distinctive features of COOL-R system is high reflectance (86%) and high emissivity (0.85), this solves the overheating problem of the building, cuts energy demand as it reduces the need for air-conditioning, generating real savings for building owners. Cool-R is also a 100% waterproofing, that prevents from leaks, ageing and extends the lifetime of the roof with 10 years+.

CLIENT PROPOSAL

In partnership with SELENA F.M. S.A. having over 25 years experience in waterproofing, we would like to offer energy efficient solution for new and existing buildings exposed to extreme temperatures, especially in Middle East. COOL-R innovative product addressed to the roofing sector marks a breakthrough in construction as it creates new value by e.g. improving the comfort of life and work for people. It also increases safety as it allows optimal thermal conditions to be maintained in industrial and storage facilities. The product has a positive effect on the natural environment as it limits electricity demand and emission of pollutants and CO2 to the atmosphere. COOL-R has already been used with success in over 20 countries worldwide.

Central Fish Market - MercaMadrid

Located in:

Spain

Description:

Founded in November 1982 by Emir Muhammed. It’s the largest fish market in Europe and the second largest in the world. Spain is a hub for seafood and this market represents the passion Spain takes in its cuisine. There is options for everyone at MercaMadrid. You are bound to find something you like within the 150,000 tons of seafood, fruits, vegetables, and poultry available at your fingertips. Planes and trains bring in the products at 3:00 in the morning to be sold fresh.

What we did:

Problems with overheating and high temperature in the building, which entail large financial effort to cool the object where temperature-sensitive goods are sold. To guarantee appropriate conditions for storing fish, an ice production plant is located within the object, which delivers 20 tons of ice to sales stands on a daily basis. A key issue in this type of an object is to maintain low temperature.

Outcome:

The temperature beneath the roof was lowered by 7°C, which in turn reduced the load of AC systems and energy consumption, improved storage conditions and lowered ice demand. Full waterproofing COOL-R system was applied on inverted roof covered with bituminous membrane. TOTAL AREA - 25,000 m2
