What We Install
Our Toronto insulation and spray foam experts work with a wide range of materials, including:
Spray Foam Insulation
Expands to seal air leaks, insulates hard-to-reach areas, and adds vapor control.
Batt Insulation
Traditional fiberglass or mineral wool batts for walls, ceilings, and floor cavities.
Blown-In Insulation
Ideal for attic spaces or retrofits with excellent coverage and thermal value.
Soundproofing Systems
Reduce noise transfer between rooms, floors, or units.
At Centennial Drywall, we understand that insulation is not a one-size-fits-all solution. Every building is different, and every client has unique needs. That’s why we take the time to assess your project in detail, considering factors such as building type and usage, local climate conditions, energy efficiency goals, soundproofing requirements, moisture control, and budget. Our experienced team then recommends the most effective insulation option—whether batt, blown-in, rigid board, or spray foam—ensuring maximum comfort, performance, and long-term value. We focus on delivering solutions that not only meet but exceed building code requirements, helping you save on energy costs while creating a comfortable, healthy indoor environment.
Frequently Asked Questions
Get answers to questions about insulation & spray foam in Toronto and the GTA.
What’s the difference between spray foam and batt insulation?
The main difference between spray foam and batt insulation is in their application method, performance, and cost.
Batt Insulation (Fiberglass or Mineral Wool):
- Form: Pre-cut rolls or panels
- Installation: Placed between wall studs or ceiling joists
- R-Value (per inch): ~R-3.5 (fiberglass), ~R-4.0 (mineral wool)
- Air Seal: Does not seal air gaps unless combined with vapor barrier
- Cost: Lower upfront cost
- Use: Standard in most residential construction
- Pros: Easy to install, Budget-friendly, Readily available
Spray Foam Insulation:
- Form: Expands on contact to fill gaps and cavities
- Open-cell: Softer, better for soundproofing
- Closed-cell: Denser, higher R-value, acts as vapor barrier
- R-Value (per inch): ~R-3.5–R-4.0 (open-cell), ~R-6.0–R-7.0 (closed-cell)
- Air Seal: Provides excellent air and moisture seal
- Cost: Higher upfront cost
- Use: Ideal for hard-to-reach spaces, energy-efficient builds
- Pros: High performance, Air/moisture barrier, Adds structural rigidity (closed-cell)
Is spray foam safe for indoor use?
Yes, spray foam insulation is safe for indoor use — when properly installed and cured.
Why It’s Safe:
- Modern spray foams are formulated to be non-toxic after curing.
- Once fully cured, they do not off-gas harmful chemicals.
- Closed-cell and open-cell foams are both widely used in residential and commercial interiors.
Important Safety Considerations:
- Professional Installation is Key
- Installers use protective equipment during application.
- Proper mixing and ventilation are critical to avoid chemical exposure.
- Cure Time (24–72 hours)
- The space should be vacated during installation and curing (usually 1–3 days depending on product).
- After curing, it’s safe to re-enter and finish the space.
- Ventilation: Proper airflow is needed during and shortly after application to prevent buildup of fumes.
Can I combine different types of insulation in one project?
Yes, you can absolutely combine different types of insulation in one project — and it’s often the best way to maximize performance based on each area’s needs.
Spray Foam + Batt Insulation:
- Spray foam in corners, rim joists, or around windows for air sealing
- Batts (fiberglass or mineral wool) in standard wall or ceiling cavities
Rigid Foam Board + Batts:
- Foam board on exterior walls for thermal break
- Batts inside framing cavities for added R-value
Soundproofing + Thermal Insulation:
- Mineral wool for sound and fire resistance between rooms
- Combine with spray foam or batt insulation for energy efficiency
Blown-In Insulation + Other Types
- Use blown-in cellulose or fiberglass in attics
- Batts or foam in vertical walls or sloped ceilings
Why Combine?
- Different parts of a home or building have different insulation needs
- Helps meet code requirements and boosts comfort
- Balances cost, performance, and moisture control
Do you provide insulation for soundproofing between rooms or units?
Yes, we provide soundproofing insulation solutions for both residential and commercial projects — ideal for reducing noise between rooms or units.
Acoustic (Soundproof) Insulation:
- Mineral wool (e.g., Roxul Safe’n’Sound) or high-density fiberglass
- Installed in wall and ceiling cavities to absorb sound
Resilient Channels or Sound Clips:
- Metal channels installed between drywall and framing
- Isolates the wall to reduce sound transmission
Double Layer Drywall with Green Glue:
- Two layers of drywall separated with a damping compound
- Ideal for home theaters, bedrooms, or shared walls
Acoustic Sealant:
- Used around outlets, gaps, and joints to block sound leaks
Insulated Metal or Wood Stud Framing:
- Staggered stud or double-stud walls with insulation in between
Perfect for:
- Bedrooms or nurseries
- Shared walls in duplexes or townhomes
- Basement suites or rental units
- Commercial offices, studios, or classrooms
Does the type of framing affect the insulation you recommend?
Yes, the type of framing—wood vs. metal—does affect the insulation we recommend, because each material interacts differently with heat, sound, and moisture.
Wood Framing:
- Lower thermal conductivity: loses less heat than metal
- Works well with standard batt insulation (fiberglass or mineral wool)
- Typically doesn’t need a separate thermal break
Recommended Insulation:
- Fiberglass or mineral wool batts
- Spray foam (for air sealing or high-performance builds)
- Blown-in insulation (for retrofits or attics)
Metal Framing:
- High thermal conductivity: transfers heat easily, causing heat loss
- Needs thermal breaks to maintain energy efficiency
Recommended Insulation:
- Batt insulation between studs + rigid foam board (to break thermal bridge)
- Closed-cell spray foam (adds R-value + acts as air/moisture barrier)
- Mineral wool (great for fire and sound resistance)

"There's a reason we keep using them...superior quality and fantastic service..."
I have personally worked with Centennial Drywall for almost 15 years. As a builder and renovator of high-end homes I rely heavily on our trade partners to execute their work the way that I would: with exceptional skill and caring. Romas and his team are always punctual; quick to offer suggestions of how to do something better; flagging potential problems before they're covered with drywall and providing exceptional quality control. Working with Centennial Drywall, it's obvious that they care about their reputation. I would highly recommend them for anyone needing drywall work.

"Centennial Drywall is the best!"
Very reliable, honest and respectful. We have been working with Romas' for about 6 years now and done dozens of projects together. Terrific craftsmanship and attention to detail. Always willing to come back for a 2nd or 3rd coordination if there were changes we had to implement.

"I am very happy with the job he did..."
I had drywall work done at my house recently by Centennial Drywall Inc. and it was fantastic. Mr. Romas is an expert and knows all aspects of drywall. He is an experienced contractor. He installed the drywall on time and within budget and used superior material for drywall. Finished the job on time.
