Insulation focused on performance and savings

Effective insulation is not limited to adding wool in the attic. It must ensure uniform coverage without joints, eliminate thermal bridges, allow adequate ventilation and maintain an appropriate R-value for Gatineau’s climate.

Our insulation services in Gatineau include:

  • Blown-in cellulose insulation (R-value of 3.7 per inch)
  • Blown-in fibreglass insulation (R-value of 3 per inch)
  • Contaminated insulation removal (vermiculite, mold)
  • Insulation topping over existing insulation
  • Baffle installation and ventilation
  • Wall and floor insulation
  • Energy assessment and recommendations

Every intervention is executed according to CNESST standards to ensure maximum safety, optimal thermal performance and total compliance with Quebec regulatory requirements. The goal is to create a comfortable, energy-efficient and long-term sustainable environment.

Schedule an inspection

Expertise, equipment and professional execution

Successful insulation relies on technician certification, quality of materials used and rigorous execution at each phase.

Precise assessment and diagnosis

We inspect your Gatineau property to assess current insulation, identify thermal bridges, verify ventilation and calculate the R-value needed to reach the R-40 to R-50 standards recommended for Gatineau’s climate. Each situation requires an adapted approach.

Superior quality materials

We use ecological blown-in cellulose (85% recycled paper, 15% fire retardants) and premium blown-in fibreglass. These materials offer uniform coverage without joints, fill all corners and create an effective thermal barrier against heat loss.

Certified professional installation

Our team uses specialized pneumatic equipment to blow insulation uniformly, installs appropriate baffles to ensure ventilation, seals all air infiltration points and verifies thickness to guarantee the specified R-value.

Each project is designed to maximize energy efficiency, eliminate heat loss and ensure comfort throughout your entire Gatineau property, winter and summer.

Types of insulation we offer in Gatineau

Blown-in cellulose insulation

Blown-in cellulose is an ecological insulation composed of 85% recycled newspaper and 15% fire retardant minerals. It offers an R-value of 3.7 per inch, one of the highest on the market. Ideal for attics, it fills all corners, creates uniform coverage without joints and offers excellent soundproofing. Its high density reduces air infiltration and maintains its performance over time.

Blown-in fibreglass insulation

Blown-in fibreglass is composed of recycled glass and silica sand. It is naturally non-combustible and offers an R-value of 3 per inch. Light and durable, it does not settle over time like cellulose can. Ideal for achieving very high R-values (up to R-70), it is particularly effective in cold climates like Gatineau’s.

Contaminated insulation removal

Old insulation can contain vermiculite (potentially contaminated with asbestos), mold, animal droppings or simply have lost its insulating properties. We safely remove old contaminated insulation, decontaminate the attic if necessary and install new high-performance insulation compliant with current standards.

Insulation topping over existing insulation

If your current insulation is insufficient (less than R-40), we can add blown-in fibreglass or cellulose over the existing insulation to reach the recommended R-value. This economical solution immediately improves energy efficiency without requiring complete removal of current insulation.

Insulation challenges specific to Gatineau

Gatineau has a humid continental climate with extremely harsh winters where temperatures frequently drop below -20°C. Insufficient insulation leads to massive heat loss, high heating bills and dangerous ice dam formation on roofs.

Many properties in the historic sectors of Hull and Old Gatineau were built with outdated insulation standards. These homes often have less than R-20 insulation in the attic, well below the currently recommended R-41. Upgrading is essential for comfort and energy efficiency.

The repeated freeze-thaw cycles of Gatineau’s climate create structural movements that can compress existing insulation, reducing its effective R-value over time. Periodic inspection and insulation topping maintain optimal performance.

Frequently asked questions about insulation in Gatineau

What R-value should I aim for in my Gatineau attic?

For Gatineau’s climate, the recommended R-value for attics is between R-40 and R-50. The Quebec Building Code requires a minimum of R-41. To reach R-50 with cellulose, approximately 13 to 14 inches of thickness is needed.

Cellulose or fibreglass: which to choose?

Both are excellent. Cellulose offers better R-value per inch (3.7 vs 3) and is more ecological, but can settle slightly over time. Fibreglass is non-combustible, does not settle and can achieve very high R-values. We will advise you according to your situation.

How long does installation take?

For a standard residential attic, blown-in insulation installation generally takes 1 to 2 days. If old insulation removal is necessary, allow 2 to 3 additional days. Commercial projects may require more time depending on the area.

Should I remove my old insulation?

Not necessarily. If your current insulation is clean, dry and free from contamination, we can simply add insulation on top. However, if the insulation contains vermiculite, mold or animal droppings, complete removal is recommended.

Does insulation help in summer too?

Absolutely! Good insulation prevents outside heat from penetrating your home in summer, significantly reducing your air conditioning costs. Insulation acts as a bidirectional barrier against heat transfers.

Are there grants available?

Yes. Quebec’s Rénoclimat program offers grants for insulation improvements. Other provincial and federal programs may also apply. We provide the necessary documentation for your grant applications.
