Decorative Magnetic Shielding
A circuit breaker box (or fuse box) in the bedroom, living room, kitchen, or other living space can be a real problem. Strong magnetic field emissions (depending on how much electric current is flowing) and electric field emissions can make the nearby area hazardous to occupy, especially for long periods. Shielding is certainly possible, but the shield must not hamper quick and easy access to the controls inside the box.
If you are handy, you can use the magnetic shielding materials listed below to make your own hinged shield. If you want an easier solution, here it is. It’s a picture (or poster) in a nice frame, with high performance Giron shielding material behind the picture. Just put a nail above the breaker box and hang the shielded picture where you need it. The bigger the shield, the better the shielding. In our tests, a 2-foot section of Giron in a 24x36 inch frame provided 50-70% reduction of magnetic field. If you need a shield larger than what is suggested here, just contact us, we will be happy to assist you.

Another alternative is to mount the Giron directly on the wall and cover it with these attractive interior window shutters. Click images below for more information or to order through Amazon:
Affordable window shutters are available in many sizes. A great way to add a decorative touch over Giron shielding material for small areas.
Breakthrough In Magnetic Shielding Flexibility
GIRON Magnetic Shielding Film, which does not contain Nickel, is unlike any other magnetic shielding material available on the market today. Suitable for high field strength applications requiring high saturation and good permeability, it is both thin and strong, and unlike Mu-metal™ it is very tolerant to bending or shaping without losing its shielding properties.
GIRON is a woven, laminated material. Cuts neatly with snips or sheet metal tools, and can be used either flat or molded into shapes for best performance.
Suitable for small shields on magnets, motors, speakers and appliances such as refrigerators, vacuum cleaners etc. Also great for lining car floor or firewall. Perfect for full or partial wall / floor shielding in rooms too! Can be glued, taped, nailed, screwed or riveted into place. Could even be used to make a (heavy weight) vest to shield a person's torso! Works with AC or DC magnetic fields (0-1000 Hz), and will tolerate temperatures from 32° to 140°F. Laminated with a 0.005 inch glass reinforced polypropylene tape which is UV sensitive, cover if installation is exposed to direct sunlight.
25.5 inch wide, 1 mm thick. Weighs 3.5 Kg/m˛ (about 15 pounds per 10 foot length). Edges are sharp!

Now achieve excellent and affordable magnetic shielding in difficult situations! Mag- Stop Plates are extra thick high-efficiency magnetic alloy (Mumetal®) plates, specially designed to provide superior shielding for electric circuit boxes, side by side computer users, and any situation where you need a flat shielding material on a wall, floor, or ceiling. Can be mounted with ordinary nails or screws, or sandwiched between the studs and dry-wall. Use zinc chromate primer before painting. In one application, we were able to achieve almost 95% attenuation of a 200 mG field!
The 24" wide "stress annealed" plates offer good magnetic shielding and are also well-suited for forming into complicated shapes. The 30" wide "fully hydrogen annealed" plates offer the best shielding available (up to 10 times the shielding effectiveness of stress-annealed alloy) and should not be soldered, welded, or heated in any way. Hydrogen annealed plates have 2 small holes pre-drilled near one end which may be used for mounting. Because of size and weight, additional shipping charges apply.
The amount of shielding that you will achieve depends on many factors, including the size and shape of the shield. When using a flat shield on a wall, floor, or ceiling to shield a source of field that is close to the shield (within 8 inches), plan to cover an area that extends at least to the 2 mG line.
1- Using your gaussmeter, slide along the surface of the wall to locate the hot spot to be shielded.
Make sure to check for additional sources of magnetic field (lights, wiring, appliances and so on), that may be located inside adjacent walls, floor, ceiling or within the same room.

Another format of MuMetal®, great for Magnetic Shield Prototyping and for Joining Mag-Stop Plates
When you need more than one Mag-Stop Plate to cover an area, how do you handle the joints? Joint-Shield is the perfect solution! This is a generous .010" thick, fully hydrogen annealed magnetic shielding alloy with adhesive backing (rated 0 - 200°F) on one side. Simply butt the Mag-Stop plates tightly together, and "tape" over the seam with Joint-Shield high permeabilty alloy. This method offers much less bulk and better appearance than the old overlap technique and provides excellent shielding integrity. Simple to use: just cut to desired length with a heavy scissors, peel the protective backing and press into place!
Joint-Shield can also be used by itself as an excellent magnetic shielding material when a 4" width and adhesive backing is desirable (wrap it around wiring and conduit, speaker magnets, even small appliances like shavers and hair dryers!). Joint-Shield can be shaped by hand, without the need for special tools, but watch the sharp edges.
4 inch wide. Specify desired length when ordering.
Ultra-Light Weight, Wide Format, Flexible Magnetic Shielding
Combining high performance nanocrystalline magnetic shielding alloy sandwiched between layers of clear PET to achieve good performance and easy handling. Very light weight and flexible, easily trimmed with scissors this material will provide good high frequency magnetic shielding for moderate to low intensity fields below 1000 kHz. Tolerates bending very well. Stack multiple layers to improve shielding performance. Maximum permeability: 70,000. Maximum flux density: 1.13T. Only 0.12 mm thick (5 mil) and 470 mm (18.5”) wide. 0.052 lb/ft˛. Hitachi Part #MS-FR 470-100M-T0
Specify desired length when ordering.
High Saturation Magnetic Alloy
First line of defense for shielding strong magnetic fields from magnets, speakers, small transformers and motors. Strong magnetic fields are harder to shield because they tend to "saturate" the shielding material. This 4" wide foil is a hefty .010" thick and has an exceptionally high magnetic saturation of 21400 Gauss and maximum permeability of 4000. Tin plated for excellent corrosion resistance and better conductivity, it can be soldered or painted.
MagnetShield typically reduces fields up to a factor of 2 or 3 depending on size/shape of the shield. Can be used in multiple layers, and/or in combination with a higher permeability alloy such as Joint-Shield for higher attenuation. Annealing is not necessary with this material. For increased shielding effectiveness, consider the following strategies:
Light Duty Economy Magnetic Shielding
For shielding jobs where you don’t need a high attenuation, this unique material is just the ticket. Only 0.010 inch thick, PaperSHIELD is flexible and can be easily cut with a scissors and shaped by hand into simple or very complex shapes. High saturation and moderate permeability make this ideal for shielding weak magnets, or stronger magnets with many layers of shielding. This material is particularly suited for achieving precise levels of partial shielding as you can add exactly the right number of layers to achieve the desired result. White paper on one side can be imprinted (by you). Peel and stick adhesive on the other side permits easy and semi-permanent mounting almost anywhere. Magnets will stick to it nicely. Really great for experimenting. 36 inches wide. Made in USA.
Magnetic Shielding You Can Wear!
Attention pacemaker wearers, welders and anyone wanting to shield their upper body from magnetic fields! The Upper Body Shield does exactly that. Composed of individual metal links which give good flexibility and plenty of air circulation. Provides about a measurable ~50% reduction of AC and DC magnetic field!
Made with 10mm diameter, shiny galvanized, 16g round mild steel rings which are butted closed. You can easily move/remove links. For example, if you don’t need the head covering, you could move those links to achieve more shoulder or heart coverage. Or you could use removed material to double up the shielding in desired places. Keep it dry as it will rust! You should probably wear a fabric liner under the shield, to minimize direct skin contact. It has some weight to it, just over 6 pounds. One size fits all.
Unique Shape for Unique Shielding Applications
Do you have an application requiring Mumetal® in un-insulated wire format? We have it in two different diameters! Stress annealed Mumetal® alloy. Wind it, weave it, braid it. Create toroids, coils, chains or simply experiment with its unique properties! Be the first to create a truly magnetic shielded garment! Spool size varies between 1-2 pounds.

Breakthrough in Low EMF Wiring!!
At last, we are proud to offer wiring which actually reduces EMF emissions to extremely low levels. Patented design incorporates both of these EMF emission suppression features: special internal wire configuration to maximize cancellation of magnetic field emissions: 2 hot, 2 neutral, and one ground wire and shielded wrapping to completely eliminate electric field emissions!
The result is a high quality wire with the lowest possible EMF emissions (over 90% reduction compared to standard wire). Replacing existing wire with MµCord is likely to be much less costly, more effective, and probably more convenient than shielding.
See How MµCord compares to standard ROMEX® carrying 30 Amps at 120V:
Includes ground wire. Note: MµCord will not compensate for unbalanced current. Make sure you correct wiring errors when you re-wire with MµCord. Not UL listed for in-the-wall wiring applications.
