I have Techshield in my home and it does reduce the attic temps, so should make the Furnace and insulation more effective at a minimum. I can say that 90% of the homes
I work on in the past 2 years have Techshield so it seems to be almost a standard with the quality builders. Two other common trends are the Closed Cell Foam being used
to spray the rafters to basically make the attic a cooled space.
Home Building Factors that affect RF Signals:
This includes Cell Phones, XM/Sirrus, and other high frequency signals, which does not include TV or FM as they are low frequency.
1. Techshield - In an area with moderate signal strength, 2-3 Bars Outside, Techshield will block 70% of the signal if the location is suburban or rural where the Cell Tower height is 200' - 300'. This is becasue Cellular is line of sight and the roof is usually the entry point given the distance between towers s approx 5 miles.
2. Stucco - The Wire Lath used to hold the stucco is a very effective barrier, I do not have percentages on this one but somewhere in the 50%-70% range if the Lath
is grounded it increased the number.
3. High E Windows with Reflective coating- These Windows are typically double pane with a reflective coating which is metallic that also blocks the signal. About 30% blocked.
4. Foil covered foamboard - High about 70% as the foil is several mm thick.
Hopefully this helps everyone understand the why and the cause and effect of highly energy efficient homes, which is very good as we all need to save on energy. Five-Bars Wireless does primarily commercial but also homes in Memorial/River Oaks/West U as the cost of the system to resolve the Cellular Signal Problem is expensive.
Questions drop me a PM.

We are in a 4 year old David Weekley home that we opted to upgrade to TechShield as the roof decking. As pointed out by many on these posts, cell phone signals are almost impossible to receive unless you stand near a window. We also have trouble receiving FM radio signals; can only get a few stations in the Houston Metroplex. Is there some solution to these problems -- perhaps some signal relay system to put outside that would strengthen the signal in the attic area? Would appreciate any help available.
