A cool insulating roof coating containing quartz® could be very efficient in saving vitality – this was confirmed in a analysis mission on the College of Gävle. The purpose of the mission, which was carried out in 2022, was to simulate the vitality consumption of a normal constructing lined with a Quartzene.® chilly roof masking. The great result’s due, amongst different issues, to the very excessive Photo voltaic Reflectance Index (SRI) of Quartzene®.
– We began the mission based mostly on the necessity to cut back cooling vitality consumption and carbon emissions. 30% of the world’s CO2 manufacturing comes from buildings – particularly previous buildings that don’t meet present sustainability requirements. Chilly roof insulation options containing Quartzene® cut back vitality necessities successfully with out the necessity to delve into the renovation of previous buildings.
Venture outcomes present vitality financial savings of 15% when Quartzene® is used as a substitute of bitumen in cool roof masking in a heat local weather. The great result’s due, amongst different issues, to the very excessive SRI of Quartzene®. Within the identify
Along with the excessive SRI, Quartzene® has a really low thermal conductivity. When the fabric is used as a practical additive in chilly roof coverings, it forces the absorbed thermal vitality to be emitted into the ambiance. In different phrases, the chilly roof coating containing Quartzene® is each reflective and insulating, not like different chilly coatings available on the market that focus solely on reflection. The low density of Quartzene® additionally facilitates the formation of movie thickness. When making use of a chilly roof insulation layer, a thick layer is vital.
The subsequent step of the analysis mission is to introduce it to the scientific group by means of a peer-reviewed scientific publication. This publication contains extra in-depth research and simulations of the vitality financial savings from the coatings used within the mission.
What are the cool roof options?
Cool roofs and paints may be utilized to roofs to replicate the solar’s rays and cut back the warmth absorbed by the constructing. In heat international locations, this will cut back vitality consumption because of decreased house conditioning, which in flip lowers vitality prices. Roof cooling options contribute to a more healthy indoor atmosphere for individuals, animals and meals. Learn extra about cool roof options on
