AIR SEALING + ATTIC INSULATION

Attic Insulation & Air Sealing in the Lehigh Valley

Better comfort starts with finding where heat and air escape. We diagnose attic deficiencies, seal air leaks and install carefully detailed insulation—including R-60 upgrades where appropriate. Serving Lehigh Valley and Northeast Pennsylvania homes with our own in-house crew.

INSULATION PERFORMANCE

How Do I Know If I Need More Insulation?

Most homeowners do not measure attic performance in R-values — they experience it through comfort, uneven temperatures, drafts, rising utility costs, and rooms that never seem to stabilize.

Insulation problems are often connected to attic air leakage, pressure-plane defects, and uncontrolled thermal transfer occurring above the ceiling plane.

When the attic assembly underperforms, the living space below often feels the effects first.

COMMON WARNING SIGNS

Signs You Probably Need More Insulation

These symptoms often point to attic thermal weakness, pressure-plane issues, or insulation that is no longer performing as intended.

🌡️

Uneven Room Temperatures

Some rooms feel hotter in summer or colder in winter, especially upper floors, bonus rooms, or spaces near attic slopes and kneewalls.

☀️

Excessive Heat Gain Upstairs

Second floors or bedrooms become difficult to cool during warmer months, even when the HVAC system is operating normally.

⚡

High Heating or Cooling Usage

The home may require longer runtimes to maintain comfort because conditioned air and thermal energy are escaping too quickly.

💨

Drafts Around Ceilings or Interior Walls

Noticeable drafts or air movement near ceiling lines, interior walls, attic access points, or upper-floor transitions can indicate attic-connected leakage.

🧱

Low, Uneven, or Disturbed Insulation

Compressed, missing, displaced, or older insulation often reduces overall thermal performance.

❄️

Ice Damming or Excessive Roof Snow Melt

Uneven roof temperatures during winter may indicate attic heat loss and thermal boundary weakness.

PREPARATION MATTERS

Why Preparation Matters

Adding insulation alone does not always solve the problem.

The attic floor, pressure plane, penetrations, ventilation pathways, and existing insulation conditions all influence how effectively a new insulation system will perform.

The strongest attic upgrades address:

01

Attic Air Sealing

Seal plumbing, wiring, framing, chase and top-plate bypasses before insulation is added or restored.

02

Attic Insulation

Install properly distributed blown insulation, commonly targeting R-60 where the assembly allows.

03

Continuous Air Barrier

Seal connected bypasses at the ceiling plane, chases, penetrations and transitions so conditioned air stays where it belongs.

ATTIC DETAILS MATTER

Building Durability. Sustained Comfort.

A complete attic upgrade addresses access openings, ventilation paths and hidden bypasses. These details work together to limit heat escape, preserve airflow and support a more durable roof assembly.

01

Attic Accesses

Treat attic hatches, pull-down stairs, knee walls and open floor cavities that undermine the envelope.

02

Ventilation & Baffles

Protect soffit-to-ridge airflow and keep insulation from blocking the roof’s intended ventilation path.

03

Ice-Dam or Roof Deck Damage Prevention

Reduce heat escape into the roof system by correcting attic bypasses and insulation discontinuities.

R-49 VS. R-60 · LEHIGH VALLEY & NORTHEAST PENNSYLVANIA

Why We Recommend R-60 Attic Insulation

For suitable vented attics, R-60 is our preferred upgrade target: more thermal resistance while the attic is already being air sealed and prepared. Pennsylvania’s adopted Climate Zone 5 ceiling table still lists R-49. R-60 is a performance choice above that prescriptive value.

Is R-60 the new R-49?

As a performance target for our attic upgrades, yes—where the assembly allows it. As a universal Pennsylvania code requirement, no. The unamended 2021 model energy code moved to R-60 in Climate Zone 5, but Pennsylvania retained R-49 in its adopted residential table effective January 1, 2026.

With the attic already accessible, adding insulation to R-60 can be a practical way to strengthen winter and summer thermal protection. We confirm space, ventilation, existing insulation and project requirements before recommending the final level.

R-60

About 22% more thermal resistance than R-49

That is an insulation R-value comparison—not a promise of 22% lower energy bills. Whole-home results depend on air leakage, installation quality, duct performance and operating conditions.

PREPARATION FIRST

Seal the attic floor before adding insulation

We address accessible bypasses and penetrations, protect ventilation pathways and detail attic access. A continuous air barrier and evenly installed insulation work together; extra depth alone cannot stop air leakage.

PROJECT-SPECIFIC GUIDANCE

Code, rebates and your home

Code compliance and utility rebates follow different rules. We check the applicable project requirements and current PPL or UGI eligibility before quoting incentives. Existing homes are not automatically required to upgrade every attic to R-60.
