As we continue with our partners to develop our own performance brand emf-protection fabrics, we are particularly excited by our 3rd generation of the already popular Blocsilver.

Blocsilver 3 has an increased silver (the expensive bit that reflects RF) content raising its emf protection shielding performance across the in-use RF frequencies of today to between 51.4 dB (900 MHz) and 39.7 dB (10Ghz)

I don’t believe there is a more economic and effective breathable and see through emf protection fabric available on the market today.

Blocsilver emf protection fabric will mitigate all normal range EMF from Cell towers, (phone masts) Wi-Fi, smart meters and cordless phones.  It will effectively shield  from 5G

What is EMF Protection Fabric?

EMF protection fabric is one of several ways to shield you and your family from microwave radiation. This versatile fabric is made into curtains, used as bedding or even a blanket.  There are different types of EMF protection fabric, most differ in strength of protection and colour.  See our EMF Shielding Fabric- Swiss Shield Ultima or Swiss Shield Naturell for other EMF protection fabrics.

What is Bloc Silver?

The Bloc Silver fabric offers the highest breathable protection available (35-60dB) and is perfect for shielding EMF radiation, possibly coming from your neighbours’ WiFi.  Made from silver and nylon mesh, some customers have previously used bloc silver as a lining in hats to reduce EMF penetration.  Drape it over your bed, windows or walls, this fabric reduces the amount of wireless radiation attempting to enter your house.  It is breathable and is perfect if you’re in a hot climate.  Bloc Silver can also be sewn and washed.  This EMF protection fabric is incredibly strong.  In fact, our bed canopies are made from it.  Not just sold as a fabric, bloc silver is also available as an option for our Y-Fry bags.

Why Should I Use EMF Protection Fabric?

EMF radiation emits from various appliances including cell phone towers, WiFi routers and even our mobile phones.  Evidence suggests that expose to EMF radiation isn’t good for your health, and can possibly lead to severe diseases such as cancer.  For more information about possible health risks from EMF radiation, click here.

In addition to protecting your home against microwave radiation, this material is a beautiful colour.  Not only does it look good, it is effortless to use.  Once up as curtains or draped on your bed, you don’t need to think it again.

7 reviews for EMF Protection Fabric- Bloc Silver – 1 Unit = 5ft x 4.92ft

  1. X is Tenshell

    My wife, who started getting serious breathing problems and bad headaches, believed she’d narrowed the cause down to radio wave transmissions from heavy use of her laptop and wireless router. I was extremely dubious of this being the likely reason, but I can only say that this fabric has helped tremendously. She has had no attack since using this product and, together with cutting down on her laptop use, appears to have her health back. I don’t believe there’s any placebo effect going on. (I am currently changing all wifi connections back to cable – which isn’t easy – that should also reduce the strength of wireless radiation in our home). When we were researching this phenomena, we were amazed at two things; how many people were getting ill and how little is said about these serious side effects. I can see this becoming a major scandal in the future, similar to our now enlightened view of smoking. We’ll probably look back at footage of people wearing VR headsets and cringe . . .

  2. Amazon Customer

    We live next to a GSM antenna. The EMF radiation level on my acoustimeter dropped significantly after shielding on of my rooms with this fabric. It’s kind of expensive but I think health is more important.

  3. Amazon Customer

    This is taken from an email I sent to the seller

    I got the fabric a little bit ago (the package took some damage in transit to the USA, but the material came through unscathed). It took me a while to set it up in a trial configuration, since it’ll be on the floor of my place under the couch and coffee table.

    If you remember, I have one of the 3 axis electro-smog detectors. Previously where I like to sit had regular bursts of ~25mW/m^2 or more, I think from my downstairs neighbor’s router. With this fabric in place it’s dropped to 2 or 3 mW… at the couch base. And that’s in a non-enclosed space! Just 6 inches away I’m still seeing the bursts.

    This fabric is fantastic.


    A little extra for this review, you DEFINITELY want a grounding cable. I have a kinda-weak grounding setup right now, and the way the fabric is laid out my heels can touch it, I have an all metal mac book laptop which actually makes a pretty excellent ground. I can feel a difference when I go to type on the laptop if my heels are touching the fabric (because the ground switches to me) so get a grounding cable and hook it up!

    Covers bed between sheet and blanket – soon ordering a second one!

  5. Michael

    It reduces RF and EMF. I hand washed in cold water, no detergent or soap, when it first arrived. This removed a slight odor and did not impact RF or EMF blocking ability. It works and is a good value. Now I proved it works, I’m looking at a bed canopy.

  6. Chidori

    This is an awesome product. I tested with my acousticom 2 meter by wrapping it with the sheet and it completely silence it. So I install it on my windows, by layering my drapes. I have cell tower radiation coming in from the windows, and this did the job. On acousticom, it shows a reduction from .10 to .02 V/m.
    Also, the price is great for this product. Note, that this product will block out your window.

  7. Fernando

    It works very well.
