Why a Henry cool roof white reflective coating?
Long-lasting reflectivity
Blindingly bright when first applied,
cool roof coatings can initially reflect
more than 88% of the sun’s heat
and UV rays. Over time, however, the
coatings weather and dust settles on the
surface, reducing the reectivity. In fact,
a white roof can lose up to 35% of its
reectivity after just 3 years.
Lower reectivity leads to hotter roof
surface temperatures. Hotter roof
temperatures lead to greater thermal shock, which reduces
the longevity of your roof. Thermal shock causes roof mastics
to separate from flashings, resulting in leaks.
Additionally, losing reflectivity will reduce energy efficiency,
ultimately wasting your investment. Loss of reectivity also
leads to greater UV radiation damage. UV rays penetrate deep
into the roof surface, causing it to dry out and crack, greatly
shortening the life of the roof.
For the best protection, demand that your roof coating has
Henry’s Dirt Pick-Up Resistant (DPR) technology. A Henry
coating with DPR technology is scientifically formulated to help
prevent dirt and dust from settling on the surface, keeping it
whiter, brighter and cooler.
In humid climates, coatings with DPR technology also resist
algae growth, which left unchecked, could lead to the same
problems caused by dirt build-up. Ultimately, a cooler roof lasts
longer, looks better and saves you more on your energy bills!
Dirt Pick-Up Resistant (DPR)
protection is the real difference
Henry’s DPR technology is an advanced polymer additive
that resists dirt at the polymer level. A Henry cool roof
white reflective coating with DPR technology helps to
prevent dirt particles from settling on a roof surface,
thereby maintaining roof reflectivity for longer-lasting
energy savings – and a longer-lasting roof.
Advanced coating science
Similar to how a non-stick coating keeps food from sticking
to a frying pan, DPR technology
keeps dirt from sticking to a
Henry cool roof white reflective coating.
Just after application, DPR technology is activated by sunlight
to cross-link polymer strands together, creating a hard, slick
surface. As a result, dirt washes off with rain water while the
coating beneath the surface remains flexible and durable.
