Guaranteed Safe Checkout

Sno-Coat™ is an advanced roof cooling paint ( Infrared thermal radiation reflector ) that can reduce internal temperatures to below ambient.

 

Our advanced roof cooling paint has superior adhesion, extended coverage as well as a higher cooling capacity.

In addition, It is also chip, crack, blister and peel resistant.

Sno-Coat™ is waterproof, unaffected by ultra violet light, flexible as well as impact resistant.

Our advanced roof cooling paint can be applied to ANY roof type including galvanized iron and also glass, with a drying time of 30 minutes in warm, dry weather.

Use Sno-Coat™ to cool your home, office, farm or factory and start saving on electricity as well as air conditioning running costs.

Sno-Coat™ prevents fungi, moss as well as algae growth on the roof.

This exceptional thermal coating is the very best available, and also encompasses a modern approach to this technology.

Sno-Coat™ is available in snow white as well as 5 light pastel shades.

ADVANCED WATER-BASED ROOF COOLING PAINT

Sno-Coat™ is suitable for use on steel, IBR, Harvey tile, cement fibre, asbestos, concrete as well as shingle roofs.

You can also use Sno-Coat™ on walls and other surface types including timber.

Some examples of ideal uses for  Sno-Coat™ are shopping centres, hotels, churches, farming warehouses, homes, factories, schools, office buildings as well as hospitals. 

Surface preparation

Ensure that the surface is free of loose paint, dirt, grease as well as grime.

In addition, the substrate must be dry prior to applying Sno-Coat™.

Application

Apply by brush roller as well as spray.

As a rule, a minimum of 2 coats are required in order to achieve the desired cooling.

Paint brushes, rollers, equipment and also spray machines can be washed with water after use.

Coverage

4 to 5 square metres per litre depending on the substrate as well as method of application.

The best surface primer to use with Sno-Coat™ is Dead-End™, Dead-End™ creates a water tight vapor barrier and also improves adhesion.

Sno-Coat™ is a wet in the can paint on coating with thermal insulation, rust prevention, waterproofing as well as thermal shock prevention properties.

Temperatures after using Sno-Coat™

Below are tables that show the temperature differences between roofs with and without Sno-Coat™

temperatures are in deg. F. Attic air means ceiling void air.

Temperatures are in deg. F. Here the roof surface temperature reaches 37 deg. C. In South Africa this can reach
to 65 deg. C ( 149 deg. F) This is where Sno-Coat truly comes into it`s own resulting in impressive cost savings.
Estimated to be R1,50 per deg. temp. difference per hour per 100 square meters of air-conditioned space.
Based on R1,56 per kwh. For a 60,000 square meter air-conditioned shopping centre at a average temp drop of 5 deg. C
this equates to a saving of About R5,000-00 per hour.
Over a 5 year period, savings amount to R330-00 per square meter, about 10 times the cost of the original coating contract.

The above temperatures are in deg. F (Average about 74,5) this relates to only 23,61 deg. Celsius. Yet at these temperatures 
only slightly above room temperature , there are huge electrical savings in air conditioning and appliance
electrical consumption as seen above.

In typical South African conditions where temperatures indoors frequently
reach over 30 deg. C, the electrical savings are massive. Bearing in mind that the higher the ambient temperatures the more effective Sno-Coat™ becomes.

A frequent question concerns payback of cool roofing. There are several angles on the answer, but generally speaking, cooling coatings are most appropriate when one is re-roofing. If the coating is applied to an existing roof that is in otherwise pristine condition, the cost equation is straightforward. The typical coverage of a cooling coating is 25 ft2 per gallon,(0,6 sq. meters per liter) (Sno-Coat® gives 6 square meters per liter reducing the application cost factor by a factor of 10!!!!

This makes a massive difference to these calculations and results) based on an application of two coats to a target thickness of 40 mils.

Cost for the material from vendors varies by 50% or more but averages about $60 per 5-gallon container when purchased in quantity. It is important to keep in mind that roof area is generally considered greater than building floor area, particularly with a steep roof pitch. For instance, a typical 1,500 ft2 home may have 2,200 ft2 of roof to be covered. The application then requires 90 gallons of coating material for a materials cost of approximately $1,100.

The cost of labor for installation depends greatly on the roof surface, on whether the coating is to be rolled on or sprayed, and on labor rates. A typical labor cost might be approximately 50cents per ft2 for the required two applications. Thus the overall application would cost about $1 per ft2, or approximately $2,200 for a typical home. With annual energy savings in Florida of $35-$140, the payback times are long–usually lasting longer than the roof itself.(With the exception of Sno-Coat®)

A completely different scenario emerges if the home is soon in need of re-roofing, however. Here the roof coating (which essentially creates a new weatherproof surface) might be seen as a way of extending the life of the roof by 5 to 10 years at half of the cost of re-roofing. The energy savings then become a side benefit.

For new homes, the situation is even more interesting. Here it is often possible to choose roofing types–such as metal roofing, tile roofing, or metal or ceramic shingles–that can be specified in a reflective white at significant additional cost.

Unfortunately, no truly reflective asphalt roofing shingles yet exist for the residential market, but this situation may change as researchers work with the roofing industry to develop new products and spread the word about the energy benefits to help create a market for the materials. For commercial buildings, a variety of reflective roofing materials are already available: Hypalon, white EPDM, and PVC single-ply membranes.

Once such products are widely available for the residential market, the economics may be significantly altered as the cost of reflective roofing becomes inconsequential.

Notes

1. Reflectivity or albedo is the hemispherical reflectivity integrated over a particular wavelength band of the electromagnetic spectrum. For the purposes of this article, the terms reflectivity and albedo are used interchangeably and refer to the wavelengths encompassing the range of solar irradiance from 0.28 to 2.8 microns.

2. Surface solar reflectivity is measured using a precision spectral pyranometer with the device alternately faced upward towards the sun and downward towards the roof to determine the ratio of incident to reflected solar radiation.
