This page is for West Hollywood homeowners who specifically have Rockwool insulation and want answers about it. Not generic attic advice. Rockwool behaves differently than fiberglass, and an audit that doesn’t account for that is leaving money on the table.

How Rockwool Products Fail - and How We Fix Them

Rockwool stone wool is tough stuff. It doesn’t rot, it doesn’t burn, and it doesn’t settle the way fiberglass does. But we’ve been inside enough Rockwool-insulated homes in West Hollywood to know exactly where it goes wrong. Here’s what we actually find:

• Rockwool ComfortBatt compressed behind drywall. When a previous contractor forced R-15 batts into a 2×4 wall cavity that was really 3 inches deep, the batts get squeezed. Compression kills R-value fast. We find this constantly in older West Hollywood condos off Santa Monica Boulevard where walls were retrofitted in the 90s. The fix is pulling the drywall section or opening the top plate and examining the cavity with a borescope, then replacing with the correct Rockwool Safe’n’Sound or ComfortBatt depth. If the wall is inaccessible, we air seal the top plates and rim joists to compensate.
• Rockwool ComfortBoard 80 with air gaps behind it. ComfortBoard is rigid exterior insulation. It’s great, but only if it’s flush against the sheathing. In West Hollywood’s older stucco buildings we regularly find installers left a quarter-inch gap because they didn’t shim the drainage plane. That gap becomes a convection loop that pulls heat right past the insulation. During an audit, thermal imaging catches this in the winter months as cold streaks along exterior walls. The fix isn’t a tear-off. It’s foam sealing the top and bottom edges, which stops the loop cold.
• Rockwool batts in vented attics that got wet. Rockwool handles moisture better than any other insulation, but it’s not magic. We see the underside of roof decking sweating in West Hollywood attics where bathroom fans vent directly into the attic instead of outside. The Rockwool at the eaves absorbs that moisture and holds it against the ceiling drywall. You’d never know until an audit finds elevated moisture with a thermal camera and a moisture probe. We trace the fan duct, correct the venting, replace the affected batts, and air seal around the ceiling penetrations.
• Rockwool Safe’n’Sound in interior walls that should’ve been thermal batts. Safe’n’Sound is an acoustical product. It has a lower R-value than ComfortBatt. We’ve audited West Hollywood homes where a contractor used Safe’n’Sound for exterior walls because it was on the truck. The wall looks insulated, but the energy bill tells a different story. During our insulation inspection we identify the product type – the color and density give it away – and give the homeowner a straight answer on what it would cost to redo it correctly.
• Rockwool around recessed can lights that weren’t sealed. Rockwool’s fire resistance is a genuine safety benefit, but the gap between the fixture housing and the Rockwool batt is still an air leak. In West Hollywood living rooms with older recessed cans, we find a visible chimney effect during blower door tests. The fix is replacing the cans with IC-rated airtight fixtures or covering them with approved Rockwool insulation shields, then air sealing the drywall-to-fixture gap with a fire-rated sealant.

Our Rockwool Home Energy Audit Process

Here’s exactly what happens when you call us for a Rockwool home energy audit in West Hollywood:

1. 1
   You call (213) 527-4062. A live person answers, 24/7. No voicemail, no call center. You tell us what’s going on – high bills, cold rooms, drafty spots. We schedule an audit, usually within a few days.
2. 2
   We show up with the right gear. A blower door assembly, a thermal imaging camera, a duct blaster, and moisture probes. Background-checked, uniformed techs. You know exactly who’s walking through your door.
3. 3
   We run the blower door test on the whole house. This depressurizes the home and shows us every air leak in real time. We walk the house with the thermal camera while the fan is running to pinpoint cold spots and missing insulation in your Rockwool install.
4. 4
   We inspect the Rockwool itself. Attic, walls where accessible, rim joists, cantilevered floors. We identify the exact Rockwool product lines installed, check for compression, gaps, moisture, and improper installation. We also run a duct leakage test if you have forced air.
5. 5
   We sit down and tell you what we found. You get real numbers: your ACH50 air leakage rate, a thermal map of your home, and a prioritized list of fixes with honest pricing. No upsell scare tactics. If your Rockwool is doing its job, we’ll tell you that too.
6. 6
   You decide what to do. If you want us to fix what we found, we do it under the Done Right Promise – lifetime workmanship. If it’s not done right, we make it right, no runaround.

Why West Hollywood Homeowners Call Walt’s Insulation for Rockwool Work

Walt Brenner started this company in 2000 after learning the trade at San Antonio College, and he’s been in attics across West Hollywood ever since. A lot of those older buildings near the Santa Monica Boulevard corridor had insulation that was, to put it charitably, an afterthought. We’re the one down the road – locally owned, owner-operated, with a published address and a real license number. Not an 800 number. Not a franchise. When you call, someone who actually does this work picks up. That’s usually Walt himself.

We install and work around Rockwool products alongside Owens Corning, Johns Manville, Knauf, CertainTeed, and Reflectix – which matters because it means we don’t have a dog in the fight. If your Rockwool is right for the job, we’ll say so. If Reflectix would work better in your West Hollywood crawl space, we’ll tell you that too. And every audit we run comes with the Done Right Promise: if it’s not done right, we make it right. No fine print, no runaround.
