The envelope is a building’s first line of performance, and the solar heat-control coating is its first layer. BECORP coats roofs and external walls to reflect part of the sun’s energy, then adds cellulose insulation and glazing film as one system.
Heat gets in through the roof, walls and glass. The coating works on the outer surface before heat is absorbed, the insulation slows what gets through, and the film controls the glazing.
Roof, wall and glazing exposure is surveyed to see which heat-entry paths matter most.
Applied as a liquid to metal, concrete or clay roofs and external walls, reflecting part of the solar energy and limiting surface heat absorption.
Reduces heat transfer through roofs, ceilings, walls and cavities, and fills irregular voids.
Applied to existing glazing to manage solar heat, daylight, glare and privacy.
Thermal bridges and the junctions between layers are specified together, so the system performs as one assembly.
Work follows the approved drawings, with materials checked against the specification at delivery.
Tested in accordance with ASTM standards C1549, C1371, E1980 and D3960. Final performance depends on certified system data, detailing and installation quality.
Reflects part of the incident solar energy before it is absorbed.
How readily the coated surface releases the heat it has absorbed.
The average Solar Reflectance Index, a combined measure of reflectance and emittance.
An exterior liquid coating with a nil VOC result in testing.
Performance is designed, installed and evidenced rather than assumed.
Survey roof, wall and glazing exposure against the project objectives.
Coordinate the appropriate energy assessment where required.
Locate the heat-entry paths: roof, walls, glass and thermal bridges.
Specify coating, insulation and film as one system, with the evidence plan.
Supply and apply each layer to the approved drawings.
Measure surface temperatures and energy use against the baseline.
A well-designed envelope can reduce unwanted heat gain and cooling demand as part of an integrated strategy. BECORP reduces avoidable demand first, then sizes supply to the actual need.
The right sequence is project-specific, and insulation and solar generation can work together.
The same infrared thermometer, the same uncoated metal roof, before and after the coating went on: 66.6°C on 11 March at 11.02am, and 35.1°C on 11 May at 11.48am. These photos come from BECORP’s own jobs.
Final performance depends on certified system data, detailing and installation quality.
Envelope performance data is prepared in the form green-building assessors expect.
Where applicable, outcomes can be measured against an agreed baseline and documented method.
BECORP provides labour and materials warranty according to the applicable project contract and product documentation.
Start with the surfaces taking the sun, and the performance you need to achieve.
