TIP: Blown Fiberglass Insulation Has An Average R-Value Of 2.5 Per 1″ Of Insulation.
When built — older DFW homes didn’t have nearly enough attic insulation installed. Adding attic insulation will pay for itself through lower cooling bills (& heating bills).
When more attic insulation is needed, it’s the 3rd best way to lower cooling bills After; 1st. Sealing Ductwork and 2nd. Sealing Air Leaks. throughout the home.

A Worthwhile Side Benefit: Attic insulation makes a home quieter. Indoor noise reduction is particularly noticeable in homes under air traffic and/or near busy roads.
Heat Travels Toward Cold — Year Round
Heat Travels Toward Cold Year-Round — until both spaces are the same temperature.
- Most people know that heat rises and escapes through ceilings during winter.
- What’s less known is that, during summer heat travels downward (from a hot attic) into the cooler living spaces through ceilings (without enough attic insulation) & through ceiling air leaks.
Image Source: Shutterstock
- During Summer: Without adequate attic insulation ceiling temps may reach up to 170F degrees. The Attic’s Ventilation is limited as to how much it can lower attic temp during summer — because outdoor air (entering the attic) — is already at a high temperature.

- During Winter: Without adequate attic insulation — ceiling temps are only slightly higher than the attic temp at night. Attic ventilation quickly removes most of the attic’s heat and replaces it with cold outdoor air.
- During the 2021 Winter Storm, on Feb. 16, 2021 — the low temperature at DFW International Airport was −2 °F. This was the coldest temperature in North Texas in 72 years.

- New DFW homes built before 1965 — commonly had NO Attic or Exterior Walls Insulation.
- New DFW homes, built 1965-1969:
- In 1965. A Federal Law Required 2″ fiberglass batt/R-8 Wall Insulation Be Installed In New Homes.
- The homes have 3.5″ thick exterior walls.
Some Builders May Have Installed:
- R-11 (3″ Batt) Attic Insulation — but this was not required by Texas.
- R-13 (3.5″ Batt) Attic Insulation — but this was not required by Texas.
- R-11 (3″ Batt) Wall Insulation — but this was not required by Texas.
- R-13 (3.5″ Batt) Wall Insulation — but this was not required by Texas.
- New DFW homes, built during the 1970’s, & 1980’s:
- Commonly had R-13 (3.5″ Batt) Attic Insulation — but this was not required by Texas.
- Commonly had R-11 (3″ Batt) Exterior Walls Insulation — but this was not required by Texas.
- New DFW homes, built during the; 1990’s, 2000’s, 2010’s — until 6/1/2016:
- Commonly had R-30 (12″ Blown) Attic Insulation — but this was not required by Texas.
- Commonly had R-13 (3.5″ Batt) Exterior Walls Insulation — but this was not required by Texas.
- On 9/1/2016 — Texas adopted the 2015 IECC.
- New DFW homes, built after 9/1/2016 — until 9/1/2021
- R-38 (15″ Blown) Attic Insulation — this was required by the 2015 IECC.
- R-13 (3.5″ Batt) Exterior Walls Insulation — this was required by the 2015 IECC.
Image Source: Pixabay.com
- On 9/1/2021 Texas adopted the 2021 IECC. As of June 2023, Texas continues to use the 2021 IECC.
- New DFW homes, built after 9/1/2021
- Attic (ceilings) Insulation: R-49 (20″ Blown).
- Wall Insulation: R-13 (inside exterior walls) -PLUS- R-5 FoamBoard Insulation covering the outside of exterior walls.

This YouTube Video Shows R-5 FoamBoard Insulation Covering Exterior Walls
(Green Insulation + Black Tape over seams)
TIP: For Newly-Built Homes — Current Texas Building Code Requires “Continuous” FoamBoard Insulation + Taped Seams.
“Continuous” means the entire outside surface of exterior walls is covered with Foam Board With Taped Seams (as shown below).
TIPS:
- A 2×4 wall, with R-13 insulation – has a Whole-Wall R-value = R-11.
- This is because the wood studs (spaced 16″ apart) have an R-Value = R-4.5.
- With R-13 Insulation Inside Exterior Walls PLUS R-5 Foamboard On The Outside Of Exterior Walls – Whole-Wall R-Value = R-17.25
- AND: The FoamBoard (+ taped at seams) minimizes air infiltration into the home.
- AND: The FoamBoard (+ taped at seams) minimizes moisture infiltration into the home.

On A Side Note…
If You’re Replacing Exterior Siding On A DFW Home
You’ll Lower Cooling Bills (& Heating Bills) By Installing A House Wrap Product Under New Siding.
Many Older (mostly brick) DFW Homes Have Some Exterior Areas That Are Covered With Siding.
TIP: Check With Your City Before Starting Work. A Building Permit May Be Required.
TIP: If You’re Replacing Exterior Siding That Covers Living Spaces, Consider This:
TIP: Add A House Wrap (Tyvek is the most recognized brand) + Tape The Seams To Notably Reduce Air & Water Infiltration

Ways Attic Insulation R-Value May Have Become Reduced Over Time
If you have had workers inside your attic — Have An Insulation Inspection — to ensure it’s still correctly installed.
- Natural Settling: After a few years, blown insulation settles a few inches — which minimally reduces R-Value.
- If blown attic insulation gets more than barely wet — the wet fibers join and create clumps.
- Wet attic insulation must be replaced.
- Disrupted Insulation — It’s common for workers to kick insulation out of their way while working in the attic. Or it may be crushed. More details below.

Article Discussing Attic Insulation Problems
This Article Discusses & Shows Photos Of:
1. Missing blown attic insulation – correct amount was never originally installed.
2. Blown attic insulation: rooms with no insulation originally installed.
3. Uninsulated Kneewalls. A kneewall is a vertical wall between the house and the attic. These are often left uninsulated.
4. Fiberglass batts falling into lowered areas of the ceilings below.
5. Open chases — a chase is the area covering fireplace venting.
6. Misaligned batt insulation. Batt Insulation was never installed properly.
7. Attic platforms & walkways — minimal or no insulation there.
8. Disrupted insulation –– insulation is no longer where it belongs.
9. Un-insulated attic access door (if door is inside living space — not needed for access door in garage).
10. Insulation is blown away from soffit (air-intake) vents. Likely caused by high winds.

Why Attics Get So Hot
Image Source: Shutterstock
Most Of The Attic Heating Occurs Due To The Sun Shining On The Roof.
This Is Called “Radiant Heat“.
Additionally, Hot Outdoor Air Enters Through Air-Intake Vents During Summer.
The sun’s heat radiates downward through the rooftop — then heat radiates downward until the heat hits solid materials within the attic. Most of the radiant-heat gets absorbed by the wood framing and/or attic insulation. Then, the lumber & insulation inside the attic disperse their heat — by conducting it downward into the house.
TIP: This Summer Heat Becomes Notably Worse With The Furnace And/Or Ductwork Located In The Attic.
(This Is Common Practice In DFW.)

A Radiant Heat Barrier helps limit the sun’s radiant-heat from getting so deeply into the attic. A Foil Radiant-Heat Barrier can drop attic temperature up to -20° F near the attic floor (which are the ceilings in the rooms below).
Radiant-Heat Transfering Into The Living Spaces Spaces Below — Is Most Effectively Minimized By
- Proper Attic Ventilation
- Increased Attic Insulation
- A Foil Radiant Heat Barrier — that’s stapled to the trusses inside the attic.

There Are Various Opinions About Attic Ventilators.
If You Open 5 Websites, You May See 5 Different Opinions.
Here’s One Opinion:
On a 90-degree day, a thermometer in your attic — will ideally read 110 degrees or less. IF An Attic Isn’t Properly Ventilated, the temperature may exceed 125+ degrees.
Source: https://www.cjonline.com/story/lifestyle/home-garden/2015/04/17/home-living-attic-fans-can-help-you-beat-heat/16632091007/
Here’s A 2nd Opinion:
If your attic is Properly Insulated to at least an R-38 / 15″ blown insulation AND is Properly Ventilated — Leave it alone.
Source: https://ktar.com/story/5154760/heres-how-you-can-ensure-your-attic-has-proper-ventilation/
Here’s A 3rd Opinion:
A significant amount of the air being exhausted May Be Coming From Air-Conditioned Living Spaces — Through Air Leaks In The Ceilings. Every opening in the ceiling is a potential source of air leakage (particularly in older homes).
Here’s Our Opinion
IF Attic Vents Are Visible From Outside The Home — The Attic Already Has Ventilation
When Built: The Home’s Attic’s Air-Intake & Air-Exhaust Venting Were Designed & Installed To Match Each Other’s Capacity.
If you increase the amount of air being exhausted — the attic’s air-intake vents are likely not large enough to bring enough outdoor air into the attic. If this is the case, additional air will come from air leaks in ceilings.
