What is Urban Heat Island?

An urban heat island is a metropolitan area that is significantly warmer than its surrounding rural areas due to human activities. The phenomenon was first investigated and described by Luke Howard in the 1810s, although he was not the one to name the phenomenon. The temperature difference usually is larger at night than during the day, and is most apparent when winds are weak. UHI is most noticeable during the summer and winter. The main cause of the urban heat island effect is from the modification of land surfaces, which use materials that effectively store short-wave radiation.  Waste heat generated by energy usage is a secondary contributor. As a population centre grows, it tends to expand its area and increase its average temperature. The less-used term heat island refers to any area, populated or not, which is consistently hotter than the surrounding area

Monthly rainfall is greater downwind of cities, partially due to the UHI. Increases in heat within urban centers increases the length of growing seasons, and decreases the occurrence of weak tornadoes. The UHI decreases air quality by increasing the production of pollutants such as ozone, and decreases water quality as warmer waters flow into area streams and put stress on their ecosystems.

Not all cities have a distinct urban heat island. Mitigation of the urban heat island effect can be accomplished through the use of green roofs and the use of lighter-colored surfaces in urban areas, which reflect more sunlight and absorb less heat.

Despite concerns raised about its possible contribution to global warming, comparisons between urban and rural areas show that the urban heat island effects have little influence on global mean temperature trends.

Benefits of Acrylic Roof Coatings

1. Easy to apply and Quick Fixing 

   Acrylic Roof Coatings create unified, uniform roofing membrane which are applied directly over the roof surface. Requiring no drilling, nailing or seam welding, these coatings save time and allow the building occupants to continue working during normal business hours. Coatings are spray-applied coatings allowing commercial roofing contractors to tailor the roofing film to meet the specific needs of the customers' roofing surface.  The Acrylic Roof Coatings offers innovative products.

This coating is applied on hundreds of millions of square feet of commercial and industrial roofs and walls.

Why Acrylic Coatings?

Cool Acrylic Coatings for Walls

Now, we have the chance to coat our buildings with special coloured coatings, highly reflective, super-durable paint-like material, that reduces building interior and exterior temperatures 10 to 90 degrees depending upon colour comparison, location and original materials being over coated. They have many benefits in the cooling of each building. Longer term savings is another key benefit. Therefore, immediate steps toward reducing global warming are a direct benefit.

The Necessity of Cool Acrylic Coatings for Concrete

Did you know that concrete stores heat from the sun and it heats up our temperature substantially due to its global use? Did you know that it deteriorates slowly to probable failure at some point in its life span? Unless it is coated, it will eventually fail and need repair or replacement due to water deterioration to the reinforcing rebar. As it is now, due to the scale and widespread nature of its use, concrete is a major contributor to the “Urban Heat Island Effect” since not painted concrete acts as a thermal heat sink in all sun exposed locations and “re-radiates” the thermally accumulated sun’s radiation into the atmosphere after the sunset. The overheated air in cities and suburbs adds more air pollution by chemical reactions which occur as the atmospheric temperatures increase. Massive carbon pollution further occurs from generation of the electricity at fuel-burning utility plants supplying the energy to run air conditioners inside millions of such buildings into the night.

Types of Roof Coating!

It is very important to know about Types of roof coatings and its pros and cons. Following are the few types of coatings which can be used for roofing:

Metal Roofing

Metal roofing is usually manufactured in steel, copper, aluminium or stainless steel and installed as sheets, even if it looks like individual tiles, shakes or stones. It can be coated in a many different types and colours of paint and other materials. Modern metal roofing frequently carries warrantees of 50 years if applied correctly.

Elastomeric coatings

A new chemistry that promises to both cover your roof and stop roof leakages, while it reflects sunlight and lowers your energy bill. The home owner can apply it themselves with a paint roller and long handled extension, without ever having to climb around on the roof.

It's too bad, but in my experience, it seldom works this way. The products stick well to bare metal and maintain their reflective qualities. I don't think they hold up well where they have been applied over other patching material.

What are Elastomeric Coatings?

Elastomeric coatings are very effective in resolving roof leakages and can be used to restore virtually all types of rooftops. It has elastic properties, and can stretch in the summertime heat and then return to their original shape without damage. Elastomeric coatings usually contain polymeric constituents, such as acrylic, and a white pigment, such as titanium dioxide, to make them dense and reflective. An elastomeric roof coating is applied thicker than paint.

Types of Elastomeric Roof Coatings

1) Acrylic Elastomeric Coatings

This is most commonly used roof coating. Acrylic elastomeric roof coatings may be used on sloped roof surfaces. The combination of durability, easy clean up and environmental friendliness makes this coating the no.1 choice.

2) Butyl Elastomeric Coatings

This roof coating is for flat roofs such as asphalt built up (BUR), modified bitumen (APP and SBS) and single ply roofing such as PVC and TPO. It has water resistance and is ideal for applications requiring a vapour barrier.

3) Polyurethane Elastomeric Coatings

These coatings are usually recommended for rubber roofs. It may also be used on modified bitumen and single ply roofing such as PVC and TPO.

4) Silicone Elastomeric Coatings

This coating is recommended for polyurethane foam because of its exceptional weathering characteristics. Commonly used over newly installed sprayed polyurethane foam and can also be used to recoat an existing silicone coated roof. 

Ceramic Insulation Coating reduces roof maintenance

A high performance Ceramic Insulation Coating has high quality UV blocking elements in order to shield your roof from the prominent causes of roof degradation - sun damage from UV and Infrared rays. Not only does the high reflectivity lower air temperature inside the house but also by reflecting a majority of the damaging UV rays away from the external of the roof, the roof is protected from cracking, splitting, weathering and ultimately from leaking. There are many varieties of coatings available in the markets which are highly reflective that can be applied over almost any roof surface.

This coating is also help in prolonging the lifespan of your Roof. How?? This coating is a spray applied, monolithic, coating system that can be applied directly over your dripping and aging roof. This process costs up to 50-70% less money than replacing your roof. It will turn out to be an added value being able to re-coat your roof each 10 or so years, giving you a new, waterproof, reflective roof membrane with half the price and time a tear-off would take.

Big Benefits of Ceramic Insulation Coating!!

Exterior wall painting life cycles can be increased by a minimum of 50% percent to as much as 100%. Combined with energy cost savings of up to 21.9% in warm locations where air-conditioning is normally preferred, these energy saving coatings applied on walls means large and measurable monetary profits to those who use them for renovates and new structure. Combine this with cool roof coatings on the same building and energy needs will be immensely reduced with environmental benefits.

This green technology in thermal barrier paints is an “Eco-logical” solution to go with for both exterior walls and roofs in order to reduce the temperature during summer and keeps warm during summer. Reducing the urban “Heat Island Effect” caused by the absorption of the sun’s radiation and the re-radiating of that heat after sunset is an essential element to reduce pollution and carbon generation. This Ceramic Insulation Coating repels radiated heat.
