Buyer Guide- Best Radiant Barriers FAQs
Do Radiant Barriers Affect Cell Phone Signals?
Many of the radiant barriers manufacturers claim that their products can block up to 99% RF signals, which is a safety measure against theft of sensitive data and information. This much practical because of the metallic composition of such radiant barriers. Cell phone signals and RF signals are quite different. So you won’t lose any cell phone service from inside your house.
Do They Allow Moisture to Pass-Through?
Radiant barriers are typically perforated and breathable, thus allowing the passage of air and moisture without collecting the same on the sheet.
Can They Be Used for Insulation during the Winter Months?
These products are generally designed for heat reflectivity purposes, regardless of the source. That implies that the same radiant barriers used to reflect heat away during summer can as well trap the temperature inside the house during winter. For such cases, we advocate for double-sided radiant barriers, for instance, the NASATECH Commercial Grade.
What is the Maintenance of a Radiant Barrier?
Of course, any product meant to serve for long will call for some maintenance and upkeeps. However, radiant barriers are extremely easy to maintain. In fact, only rarely will they require a simple dusting should the attic space be poorly ventilated.
What Features to Consider when Buying a Radiant Barrier?
Reflectivity and Coverage
This is the most critical factor to consider since radiant barriers are primarily based on their contact area for efficiency. All radiant barriers highlighted in this guide meet and exceeded 95% reflectivity, which is the minimum standard as per ASTM. So anything short of that benchmark is below-par and certainly not recommended.
Type of Material
Another vast difference between radiant barriers is the type of material. While most brands usually employ aluminum foil on the core, some prefer using aluminum particle finishes instead of foil.
Nonetheless, some radiant barriers, like NASATECH Commercial Grade features woven Mylar Scrim to reinforce the sheet. Other products like ARMA FOIL utilize polythene to safeguard against tears and punctures. Since the foil method has been tried and found genuine, plus it exceedingly meets the radiant barriers standards; definitely, it can be a good investment.
Make sure the radiant barrier fully complies with ASTM C1313, which states all guidelines for these products from tensile strength and reflectivity, to permeability and corrosivity. It is always better the one that meets and exceeds the ASTM standards.
Other features to consider include roll width, toxicity, humidity resistance, and reasonable warranty terms such as money-back guarantee. Also, you can ideally go for a substantial radiant barrier for added sturdiness.
Irrespective of which model best fits your needs, you can rest assured that your house, both whether inside or outside, it will benefit from it. The above-mentioned radiant barriers are the most affordable, just a one-time expense, and they will last for a great course, probably saving you from huge energy bills. They are the best radiant barriers available on the market.
