Fiberglass insulation has been the workhorse of American homes for decades — and for good reason. It's affordable, proven, and when properly installed gives you reliable thermal performance for the lifetime of the building. At Premier Insulation, fiberglass is the product behind some of our most popular services — attic reblows, room additions, drill-and-blow upgrades for older homes, and full new-construction batt installs across the OKC metro. We install Owens Corning products exclusively because they hold up to Oklahoma's climate, qualify for OG&E and Edmond Electric rebate programs, and have the recycled-content credentials homeowners increasingly want.
Fiberglass works best as a thermal barrier — it slows heat from moving through walls, attics, and floors. It's the right tool when the building's air sealing is already solid (or when you're pairing it with separate air-sealing work) and you need cost-effective R-value. For older homes especially, fiberglass is often the most practical upgrade because it can be added through small holes drilled into existing walls — no demolition required.
Types of Fiberglass We Install
Fiberglass Batts
Pre-cut blanket-style fiberglass that fits between wall studs, floor joists, and ceiling rafters. Best for new construction and major remodels where the framing is open and accessible. Owens Corning batts come in standard depths matched to typical framing dimensions, so installation is fast and clean. R-value depends on thickness — typically R-13 for 2x4 walls, R-19 to R-21 for 2x6 walls, R-30+ for ceilings.
Blown-In Fiberglass
Loose-fill fiberglass blown to a target depth. Standard for attic floors because it fills around obstacles, irregular framing, and ceiling-mounted fixtures without leaving gaps. Also the right answer when you're adding insulation on top of existing material — the new layer settles cleanly over the old. Most attic reblows in Oklahoma target R-38, which works out to roughly 13 inches of blown fiberglass.
Drill-and-Blow Fiberglass
A retrofit technique for adding insulation to walls that are already finished (drywall up, sheetrock in place) AND have no existing insulation in the cavity — most commonly pre-1920s houses and garages where the original walls were never insulated. We drill small access holes between studs and blow fiberglass into the cavity to the right density. The homeowner or general contractor handles plug-and-patch and repaint. Lets you upgrade an older home's wall insulation without tearing into the drywall — but only works on empty wall cavities; if the wall already has any insulation, the cavity needs to be opened up the traditional way.
Blow Behind Netting (BBN)
A new-construction technique where we staple a fabric netting to open studs, then blow loose-fill fiberglass behind it to fill the cavity completely. The drywaller covers it like normal. BBN gives you the gap-filling advantage of loose-fill (the way it works around wires, plumbing, and irregular cavities) while still being a proper option for open framing — sort of a middle ground between batts and a true blown-in install. Best for new construction or open-wall remodels where you want the best fill possible before drywall goes up.
Blown-In Insulation is a Good Investment
Blown-in fiberglass is more thermally efficient than batts because it's installed as a monolithic layer with no seams or gaps. Industry studies have shown blown-in performs up to 22% better than batts at the same R-value. Adding blown-in fiberglass to your attic is one of the fastest paybacks of any home improvement project — typically 3-5 years from energy savings alone, often less when paired with an OG&E rebate.
Owens Corning Partner
Owens Corning Pink insulation has been our fiberglass product of choice since we opened in 2006. They use sand and an average of 40% recycled glass in manufacturing, all products are made in North America, and they hold up to Oklahoma's seasonal extremes better than most alternatives we've tested. Their PINK lifetime warranty also gives homeowners confidence the material will perform for the long haul.
PROPINK Features:
- •Made of sand and recycled glass — average 40% recycled content
- •Non-corrosive and non-combustible
- •Will not absorb moisture or support mold growth
- •Dry insulation system — no water, no drying time
- •Installs into any wall cavity without gaps or compression when done right
- •Backed by Owens Corning's lifetime warranty
Where We Install Fiberglass
Attic Reblows (OG&E rebate eligible)
The single most cost-effective insulation upgrade most Oklahoma homeowners can make. We blow new fiberglass on top of (or in place of) existing attic insulation to bring it up to a current Oklahoma R-38 target minimum. Most jobs qualify for OG&E's HEEP rebate — we'll help you fill out the paperwork.
New Construction Walls & Ceilings
When the framing is open and you're building from scratch, you've got two good options: batts (fast, clean, code-compliant for standard cavities) or blow behind netting (better fill around wiring, plumbing, and irregular framing). We work directly with builders and remodelers across the OKC metro and recommend whichever fits the project better.
Room Additions & Bonus Spaces
Adding a room? We'll install batts in the new walls and ceiling so the addition matches (or exceeds) the existing home's thermal performance. Common pairing with our attic reblow service so the whole house ends up consistent.
Older Homes (Drill & Blow)
Pre-1920s homes and garages often have little or no wall insulation. Drill-and-blow lets us upgrade the walls without tearing into the drywall — small access holes, blown fiberglass to proper density. The homeowner or general contractor handles plug-and-patch and repaint. Result: a dramatically more comfortable home with no demolition.
Sound-Dampening Interior Walls
Fiberglass batts in interior walls don't add much R-value where it matters (since both sides are conditioned), but they significantly reduce sound transmission between rooms. Common in master-bedroom walls, home offices, and media rooms.
What to Expect on Install Day
- 1
Pre-installation walkthrough
Our crew arrives and walks the space with you to confirm the scope. This walkthrough is about confirming access points, materials staging, and any concerns you want addressed before we start.
- 2
Prep & access
Floors and finished surfaces get protected. For attic work, we set up the blow rig and run hose to the access point. For drill-and-blow, we mark and drill access holes in the wall.
- 3
Installation
Batts get cut and placed; blown material gets blown to the target depth or density. Most residential reblows are complete within an hour; larger commercial work may take longer.
- 4
Cleanup
We clean up all dust and debris and remove all masking. We leave your space cleaner than we found it. (Note: for drill-and-blow jobs, plug-and-patch on the drilled holes is handled by the homeowner or general contractor — not included in our scope.)
- 5
Walkthrough & rebate paperwork
Final walkthrough with you. For OG&E rebate jobs, we hand you the paperwork already filled out — you just sign and submit.
