Don’t Blow Insulation Around a Heat Source Without Checking It First
Attics can contain:
- Masonry chimneys
- Metal vent pipes
- Furnace or water-heater flues
These are different from ordinary framing.
Depending on the venting system, required clearances from combustible materials may apply.
Why Is This Important Before a Top-Up?
Loose-fill insulation can hide the area once installation is complete.
If a required clearance is missing, simply burying the detail makes inspection harder.
What Should the Contractor Identify?
Before insulation work, determine:
- What type of vent or chimney is present
- Whether an approved clearance detail exists
- Whether fire-blocking or another approved assembly is required
Don’t Guess the Clearance
Requirements vary by:
- Equipment
- Vent type
- Listing
- Building requirements
The appropriate qualified trade should verify uncertain conditions.
Why Envirotech Checks First
A good insulation project does not focus only on reaching a target depth.
It also respects:
- Ventilation
- Electrical details
- Heat-producing equipment
Energy Efficiency Should Never Come at the Expense of Safe Clearances.
Envirotech Exteriors can identify attic areas that require further assessment before blown-in insulation is installed.
