Passive Thermal Control
SERVICES
Whether the objective is to minimize internal temperature for occupant comfort or for heat sensitive contents, the use of heat reflective coatings is the most effective passive system available to significantly minimize or in some cases eliminate the need for air conditioning or additional shade structures.
Consisting of a primer (enhancing adhesion and resisting corrosion, mould and fungi) and two layers of heat reflective topcoat, Solacoat forms a protective coverage that shields, maintains and enhances the roof and walls for up to 15 years while keeping the internal temperatures cool in the extremes of summer. With versions suitable for both metal and porous surfaces Solacoat is available in a limited selection of colours with lighter shades delivering the most effective heat reduction. Can reduce internal temperatures by up to 12 degrees Celsius or more from ambient temperature in hot weather.
Step 1: Solacoat Primer
Solacoat offers four types of primers depending on the substrate. Either Solacoat WB Metal Primer (for metal substrates), Solacoat Asbestos Primer, Solacoat CS Metal Primer for Heavy/Mild Constructional Steel, Stainless Steel, and Steel Rail Tracks, or Solacoat CP Porous Primer (for concrete walls, tiles, and non-glazed terracotta tiles). Speciality Primers are also available for specific applications.
Solacoat WB Metal Primer, with excellent adhesion to all non-construction metals, contains proven rust inhibiting agents to halt corrosion.
The Solacoat CP Porous Primer is designed to fill relatively small imperfections in the aged but mechanically sound tile surface, and/or any porous surfaces. Addresses durability, aesthetics.
Step 2: Solacoat Topcoat
Solacoat Topcoat is a revolutionary water-based acrylic coating that contains a unique membrane additive, which reflects up to 84.9% (cream) of the sun’s solar rays, whilst assisting in reducing your CO2 footprint for air-conditioned buildings.
A superior resistance to heat absorption, Solacoat Topcoat has a higher solar reflectivity than corresponding conventional paints. The lighter colours have a higher TSR Value and SRI Rating (105.9) due to the significant incorporated technology and solar reflectance.
Solacoat Topcoat Cream has a Solar Reflectance of 84.9% meaning it reflects that percentage of the sun’s rays before they hit the surface of a roof/wall back into the atmosphere. The 15.1% of the rays that are absorbed through the coating are then released by Solacoat’s high 0.88 thermal emittance value, which means the coating is then only absorbing 1.81% of the sun's heat.
