eShield Attic Insulation in Greater Boston

Why Check Your Attic?

Your roof protects your home from the outside, but your attic shapes how well that protection performs. In winter, rising heat escapes through thin insulation and warms the roof deck, which is how ice dams start. In summer, a sun-baked roof radiates heat down into the attic and pushes temperatures past what an HVAC system can keep up with.

Air leaks and moisture make both problems worse. Unsealed gaps around light fixtures, framing, and attic hatches let conditioned air escape and humid air in. When insulation is thin or uneven, or when a roof leak has compromised it, both the roof and the living space below suffer. eShield attic insulation is built to address these conditions.

How the eShield Radiant Barrier Addresses Attic Heat

In summer, the sun heats the roof deck and the underside radiates that heat down into the attic. The eShield radiant barrier is a reflective foil designed to intercept this radiant heat, reducing how much of it passes into the attic space below.

The radiant barrier cuts summer heat buildup and keeps upper-floor temperatures lower. It installs without itchy fibers and performs in both hot and cold climates. It may also reduce the conditions that contribute to ice dam formation.

Blown-In Attic Insulation and R-Value

Blown-in insulation is loose material that gets blown across your attic floor to fill it in evenly and slow the heat moving between your attic and the rooms below. R-value is simply the number that tells you how well it does that.

The higher the R-value, the better it resists heat moving through it. Older homes often fall short here, because insulation settles and flattens over the years, or a past roof leak leaves it damp and far less effective. Adding blown-in insulation brings the R-value back up.

Qualifying eShield blown-in installations may include warranty coverage on the installed R-value, subject to manufacturer terms. If the insulation ends up below the R-value you paid for, the attic is refilled at no charge, per the applicable certificate. That coverage requires installation by a certified installer.

Signs Your Attic May Need Better Insulation

Observable conditions that can point to attic problems include:

• Upstairs rooms that are too hot in summer or too cold in winter

• Heating or cooling bills that rise without a clear explanation

• Ice dams forming along the roof edge

• Snow that melts unevenly across the roof

• Drafts or uneven temperatures throughout the home

• Insulation that is thin, uneven, compressed, or damaged

• Moisture, condensation, or a musty smell in the attic

• Insulation affected by a roof leak

• An HVAC system that runs continuously in extreme weather

These signs can overlap with roof and ventilation issues. Capital's evaluation looks at ventilation and air sealing as well as roof condition, not just insulation.
