Cold applied liquid membranes are sweeping the market over the last few years and are fast becoming the roofer’s first choice. The membranes for roofing are not only pleasing to the eye, but also with the minimum training of a few days experienced roofers can install cold systems with ease.
As insurances on buildings has risen in years due to fire risk, liquid membranes do not require heat for application unlike traditional systems. Roofing companies can apply the membranes and their own public hability insurances have dropped considerably. Most of those different membranes have key features some are hybrid polymers systems others have been on the market since the 1950’s onwards and for these reasons and slight changes in their application are going from ‘strength to strength’.
Cold systems can be applied in low temperatures most 0-50 degrees, this means all year-round applications can be made. Most of the modern systems have 20-30-minute lure time. This means that the roofs can be float trafficked on busy sites, buildings almost immediately.
Cold applied roof membranes now come with a B roof (T4), the top rating for fire performance for a flat roof system and with a BBA certification to match these meet modern building standards.
Most cold applied system membranes have a fully reinforced fleece, matting running through the layers of liquid waterproofing and are highly flexible. Also, they are tough to meet the demands of damage most roofs receive as the years go by.
As the liquid membrane market grows with each passing year, we can see traditional roof systems in a decline. This means that as roof systems go, we must move with the times. In conclusion, Cold applied liquid roofing membranes are here to stay!
