Flame-Free Warm Roof Refurbishment Solution at Pear Tree Infant School, Derby

Pear Tree Infant School required a full flat roof refurbishment following an initial survey that showed that the existing system had come to the end of its serviceable life.

The existing roof finish was stripped back from the metal deck and a new warm roof system installed. The key objectives with this refurbishment was to achieve an average u-value of 0.18 W/m2K thus improving the thermal efficiency of the building.

Alumasc installed a new Caltech UV Cold Applied Liquid Warm Roof System with a tapered insulation scheme to improve the drainage efficiency and prevent future standing/ponding water areas.

The whole installation was carried out using ‘flame free’ products and methods.

To help further improve management of rainwater Roof-Pro ProDrain Outlets were installed – this guaranteed the correct detailing from the roof to the outlets. The existing lightning conductor system was also upgraded to the Roof-Pro Lightning Conductor Clip System.

Finally, a defined Caltech Walkway System was added to provide a more durable surface for traffic and again help to maximise the life of the roof.

Caltech UV has an extended life cycle due to its enhanced UV resistance and is highly adapted to cope well when exposed to sunlight thus avoiding UV Degradation. Caltech UV cures to form a seamless, durable and weather-resistant waterproofing solution.
