The Science of Coolness: Creating "Shade" Beyond the Numbers
Now that extreme summer heat has become the norm, parasols have evolved from simple shade providers into "protective equipment for your body." You’ve likely seen terms like "UV cut," "light shielding," and "heat shielding" in stores.
While these may sound similar, they actually serve distinct purposes and target different things.
First, "UV cut" is a function designed to protect your "skin." It blocks ultraviolet rays in the 290nm–400nm range, preventing sunburn and photoaging.
However, this alone does not provide "coolness." Next, "light shielding" is a function to protect your "eyes." It physically blocks visible light in the 400nm–800nm range, reducing glare and ensuring a clear view.
And the feature into which we pour our greatest efforts is heat shielding—in other words, the ability to protect your "body temperature."
Fabric performance vs. product capability.
When evaluating the cooling performance of a parasol, as professional manufacturers, we believe it is important to look beyond mere fabric specifications.
-
Heat Shielding Rate (Fabric Performance): This measures how much heat the fabric alone resists during official laboratory testing.
-
Heat Shielding Effectiveness (Product Performance): This is our own proprietary metric, measured in an open space that closely replicates the environment of actually using a parasol.
No matter how excellent the fabric is, it is meaningless if that performance is not fully realized once it is crafted into a finished parasol. AMVEL's "HEATBLOCK" is designed with a relentless focus on maximizing this heat shielding effectiveness.
The "Silence" Created by Aggregated Metrics
Our flagship "HEATBLOCK" series clears the following metrics at an exceptionally high level:
-
100% UV Cut
-
100% Light Shielding Rate
-
100% Visible Light Cut
-
99.9% Near-Infrared Cut
By thoroughly blocking even near-infrared rays—the root cause of heat—we create a quiet, cool space under the parasol that feels just like a "portable patch of shade."
Beyond design and price, ask yourself: does it offer "true coolness" backed by hard data? As you choose a companion for this summer, be sure to check for those metrics.
