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.
