FAQ's

FACT

• All of C.M. Security’s stainless windows are fabricated from 14 gauge, 304 stainless steel.

This raw material was chosen not only for its superior maintenance qualities compared to ordinary 12 gauge cold rolled steel, but also for its far superior yield strength +38%, tensile strength +48%, hardness Rockwell (B) +45% and ft. lbs. of impact resistance +57%.

 

FACT

• All of C.M. Security windows are stainless steel back welded for strength and sealed with silicone sealant with a life expectancy of 50 years +.

This superior manufacturing process allows C.M. Security to achieve the strength desired for the demanding needs of modern day correctional institutions, while eliminating the inherent  problems of hairline cracks and pockets within the continuous welds propagating corrosion, thus weakening the weld and window over time.

 

FACT

• C.M. Security Group uses 1” diameter fixed bars that are totally separate from the ventilator.

These 1” diameter fixed bars as compared to the rest of the industries 7/8” pivoting bar allows you the added security of 100% greater cutting resistance, 43% greater deflection resistance and 50%  greater impact resistance.

 

FACT

• C.M. Security Group heat treats their own security steel thus conforming to ASTM 627 and ASTM 629 under very strict quality control.

 

FACT

• C.M. Security Group uses a superior alloy steel for security bars and flats as opposed to our competitors carbon steel.

FACT

• C.M. Security will not use pivoting bars.

Welding of a ventilator to a 7/8” pivot bar destroys the tool-resisting properties in the heat affected zones due to the high carbon content of the pivot bar.

Rotating bars will not function properly if there is deflection on the 7/8” bar or corrosion of the bearing.

 

FACT

• C.M. Security designs all its windows with the security steel element on the warm side of the wall cavity.

This design eliminates unnecessary sweating due to temperature fluctuations within the cavity and protects the security steel from corrosion. Competitive 12 gauge ferrous metal windows allow this corrosion to take place, thus eliminating the rotating bar and weakening  the security element.

 

FACT

• C.M. Security operable windows are 100% weather stripped.

The superior weather performance of this design removes the ventilator from the security bar and allows for 100% weather stripping resulting in much better resistance to air infiltration and water penetration.

 

FACT

• C.M. Security windows, both fixed and operable have significantly better resistance to air infiltration and water penetration.

This is achieved through superior design and attention to details like silicone back sealing of all joints and mortar caps.  Over time corrosion in competitive continuous welds will appear with air + water performance deteriorating.

 

FACT

• C.M. Security ventilators are extruded aluminum  reinforced by 3/8” diameter stainless steel side arms and mechanically assembled by 2 stainless steel security screws at each corner.

These extruded aluminum ventilators do not have the inherent problems of ferrous metal welded joints that corrode and weaken over time. They are fully compatible with stainless steel and will not result in galvanic action.  A sharp impact on a ferrous metal ventilator welded to the security element breaks the weld.

 

FACT

• C.M. Security aluminum ventilators are as strong or stronger than competitive hot rolled steel ventilators.

The holding power of the 2 stainless steel screws in each corner of the extruded ventilator  will withstand the test of time. They will not corrode at the seams like a ferrous metal ventilator.

 

FACT

• C.M. Security aluminum ventilators can be separately removed for easy maintenance.

This is a result of superior design that allows for a maintenance crew to replace the ventilator in a few minutes instead of the time and labour intensive job of cutting out the entire steel window which would be the case with competitive windows.

 

FACT

• C.M. Security uses extruded aluminum muntin shrouds  on all its standard windows.

This is merely a cover to the security steel and must not be considered a security component.  They are screwed in place and back sealed.  They are fully compatible with 304 stainless.  They will not rust nor can they be removed.

 

FACT

• C.M. Security stainless steel windows can easily be finished with Drylac baked-on powder coating.

This is a superior product applied over non-ferrous metal.  With steel windows it is impossible to successfully coat some of the areas or assemblies resulting in rusting. 

 

FACT

• C.M. Security takes pride in the aesthetics of their finished product.

All aluminum components will be color matched to standard stainless steel 2-B finish.

FACT

• C.M. Security stainless steel windows allow almost double the net glass viewing area to that of a competitive steel window.

The 14 gauge stainless frame is designed with a small but yet stronger profile allowing for the increase in net glass.
