Thicker ¼" Glass & Windshield STC Mods and
Whisper Soundproofing Packages
Through our research over the last 20 years, we have
developed effective methods and modifications to reduce the sound transmission level or
"perceived decibel noise level" to the pilot and co-pilot by some 4-6 db.
Doesn't sound like much you say? Let me put it another way. Usually in
most all GA aircraft and including most Mooneys, or at least the ones prior to the current
production models (fitted with the composite interiors), normal conversation and true
acceptable noise ambiance was strained-at best. In fact, most audio experts would term ANR
headsets were nearly an absolute necessity for prolonged use and/or to assist in hearing
protection.
 New Style One Piece
Curved Current Production
(M20J/K/M/R etc.)
1/4" and 3/8th Thick Windshields
Our STC'd 1/4" and optional 3/8th thick M20J/K "Concave"
OEM style windshields make an un-believable difference in the overall ambiance of the
Mooney operating experience. Besides adding some 2-3 MPH in cruise, installing the
compound curved newer style windshield is perhaps the single most important item
you can do to aid in quieting the din of your older Mooney.
Even if you own a newer style 201, 231, 252, or even a TLS etc., our ¼
& 3/8th thicker Windshields and Side Glass Mods will make a definite difference in
cabin sound levels as well as add a certain measure of protection for the always present
"bird strike" possibility.
Mooney Sound Deadening Factoid
The Mooney cabin structure is "different".
It is not monocoque (stressed skin) constructed like nearly all aluminum skinned GA
aircraft. It has the stronger triangulated 4130 steel tube fuselage tubes to carry the
loads and consequently, (besides looking kind of goofy with out it), the M20's outside
cabin skin is only there to keep the wind and rain off the pilot and passengers, so to
speak. This means the largely slab sided cabin skin is far "looser" or less
stiff than most conventionally designed GA aircraft, and consequently it vibrates in
harmony with the blasts from the prop blade passages.
Anything (like thicker or stiffer glass) which can stiffen up the cabin skin
assists in keeping the noise transmission down. Think of it like sitting inside a kettle
drum!
Our research has shown that our specially designed thick side glass goes a long way to stiffen
the entire M20's cabin skin structure, and thus greatly assists in reducing the noise
transmission level far more than installing thicker glass in "normal" GA
aircraft.

 ¼" Thick Side Glass Mod
This mod is one of the most popular we have ever introduced! It
replaces your old 1/8th thick (so thin as to be actually flimsy)
side glass with the far stiffer 1/4" glass. This mod is vital in our
soundproofing process and strongly recommended to virtually every Mooney owner
in his quest for an acceptable and hearing safe cabin ambiance.
Out Thicker Glass Mods are available for every model M20 in three colors
or tints, Green, Clear, and the current production and ever
popular Smoke Tint.

In short, when considering the minimal
weight difference and expense (compared to "stock" thin
& flimsy glass), and considering the advantages:
There is no reason ever to allow stock (flimsy or thin) glass to remain
in your Mooney!
