Covid-19 Update
Winser Doors is open for business! We are happy (and a bit relieved) that in accordance with the Ontario Government we can open our retail outlet. If you require a new garage door or parts for your existing door, our 10,000 square foot facility is stocked up and ready to help! Of course we will be practicing physical distancing (6') and asking all that come use the hand sanitizer at the front entrance. We are limiting the number of people in the showroom at any one time to three, so you are encouraged to call 519-658-5167 and set up an appointment!

Southern Ontario’s Choice for Radio Frequency Shielding Doors

Are you looking for solutions to block radio frequency interference? If so, Winser Doors is here to help you. We provide radio frequency shielding doors in Southern Ontario, Kitchener, Waterloo, and surrounding areas. A Radio Frequency (RF) shielding door assembly minimizes the amount of electromagnetic energy and radio frequency that can be transmitted across the opening. Often radio frequency shielding frame and door assemblies are designed to achieve both radio frequency and acoustic attenuation.

Door and frame assemblies meet combined radio frequency standards. The drop in energy transmitted across the opening (attenuation) is measured in decibels. The performance can be specified as a particular attenuation at a particular frequency (i.e. 40dB at 1GHz), as a consistent attenuation across a band of frequencies (i.e. 25dB from 400Mhz through 10GHz), or as a varying attenuation across a band of frequencies (i.e. 25dB at 200Mhz, 35dB at 800MHz, 40db at 1.2GHz).

These assemblies are provided with RF gasketing that is important for product performance. Materials can be provided in stainless steel or mild steel formats to meet requirements for a wide range of applications. Get in touch to learn more about our services.
