Most roofing systems are made up of GI sheet. Fasteners and screws are
bolted in between each overlaps so as to prevent water leakage. To exaggerate a
situation, imagine that your roofing is made up different sheets with spaces in
between just like this photo.

How can you solve this problem? Or how can you join these two slabs? Probably you’ll do it like this;

Putting a brace then connecting bolts or screws on both sides will do the job. But what can you do to make this arrangement more durable?

Imagine that
your roof made of GI is composed of many non-continuous materials. They may be
bolted or screwed in between their overlaps yet the connection would be stronger
if something will hold them together. Remember also that your GI sheet as well
as your screws and bolts do corrode hence limiting the life of your connections
and roofing system in a span of 1 to 2 years. With respect to typhoons and wind
uplifts a need of reinforcement is necessary to obtain a stronger or a durable
roofing system.
You could spray polyurethane foam (ECOFOAM) on your
roofing system making it strong from typhoons and wind uplifts. You could
Google polyurethane foam and find out that it has a very good adhesion
property. It means that you’re putting a brace and screws at the same time when
you install ECOFOAM on your roofing system. Good thing
with ECOFOAM is that it offers lot
of advantages except that it makes your roofing system durable. These are facts
and you can Google Polyurethane foam over these claims.- ECOFOAM is seamless. Since it is a sprayed foam at room temperature that is, from liquid to a hard solid at normal temperature no gaps will be seen in the foam.
- ECOFOAM is self-flashing. It can serve as your flashing material since ECOFOAM can seals those cracks and crevices while foaming or a volume expansion (of the foam) happens.
- ECOFOAM has very high R value. Because Ecofoam is a Polyurethane type of foam it is inherent that the foam has a high R-value or resistance to heat. Try to look for PU foam R-value and you will be surprised that it is one of the highest. Other higher than it has a very complicated technology making it either unavailable or very expensive. Try to look ECOFOAM in Manila, Cebu or Davao and you will see that ECOFOAM is available nearby.
- ECOFOAM is sustainable. Ecofoam can even last for 20 to 50 years. Polyurethane foams are really durable. Though they are non-UV resistant but a good coating system will really make your roof last very long. Your substrate (GI roofing) will be protected from harsh environment enabling you not to change it for a very long time.
WOW! this is how technology really works!
