Overview

What Is Fiberglass Insulation?

Fiberglass insulation is one of the most widely used and trusted insulation materials in North America. Made from fine glass fibers, it traps air to slow heat transfer and is available in batts, rolls, and loose-fill forms. ApexSeal NY installs fiberglass insulation to the highest standards across residential and commercial projects in NY, NJ, and CT — ensuring proper coverage, correct R-value, and code compliance on every job.

How It Works

Our Process & Approach

01

Site Evaluation

We assess your existing insulation levels, identify thermal bridging, and determine the correct R-value for your climate zone and building type.

02

Material Selection

We select the appropriate fiberglass product — faced or unfaced batts, rolls, or blown-in — based on your application, framing dimensions, and performance goals.

03

Vapor Barrier Planning

We determine the correct vapor retarder placement based on your climate zone to prevent condensation and moisture damage within the wall assembly.

04

Precision Installation

Batts are cut and fitted snugly into every cavity without gaps, voids, or compression — the most common installation errors that reduce performance.

05

Air Sealing

We seal penetrations, electrical boxes, and framing gaps before insulating to maximize the thermal performance of the fiberglass installation.

06

Final Inspection

A thorough walkthrough confirms complete coverage, correct facing direction, and compliance with local building codes before project sign-off.

FAQ

Common Questions

What R-value do I need for my home in NY, NJ, or CT?

The Northeast falls in climate zones 4–6. Typical requirements are R-49 to R-60 for attics, R-13 to R-21 for walls, and R-19 to R-30 for floors over unconditioned spaces. We assess your specific situation and recommend the right value.

Is fiberglass insulation safe to handle?

Our crews use proper PPE during installation. Once installed and covered by drywall, fiberglass poses no health risk to building occupants.

How does fiberglass compare to spray foam?

Fiberglass is more affordable and performs well when properly installed. Spray foam provides a higher R-value per inch and superior air sealing. We can help you choose the right option for your budget and performance goals.

Can fiberglass insulation get wet?

Fiberglass does not absorb water, but wet insulation loses R-value and can harbor mold if not dried. We address any moisture issues before installation and ensure proper vapor management.
