Question 1

How many days should I allow for blown-in cellulose installation in a Moncton bungalow?

Accepted Answer

Most blown-in cellulose installations in a typical Moncton bungalow take just one day to complete, though the timeline depends on your specific project scope and existing attic conditions.

For a standard attic-only cellulose top-up (bringing existing R-20 to R-50/R-60), professional installers typically complete an 800-1,200 square foot bungalow in 4-6 hours. This includes setup, blowing the cellulose, cleanup, and a final inspection. The actual blowing process is quite fast — a two-person crew

Question 2

What is the settling rate difference between blown-in cellulose and blown-in fibreglass over 20 years in a Fredericton attic?

Accepted Answer

Blown-in cellulose settles approximately 15-20% over its lifetime, while blown-in fibreglass settles only 2-5% — a significant difference that affects long-term R-value performance in Fredericton's climate.

The settling difference between these materials comes down to their physical properties and how they respond to Fredericton's temperature cycling and moisture conditions. Cellulose is made from recycled newspaper fibers that compress under their own weight over time, especially when exposed

Question 3

How much blown-in insulation do I need for a 1500 sq ft attic in Rothesay? | Insulation IQ?

Accepted Answer

Rothesay sits in the Saint John River valley, where winters are reliably cold and heating seasons are long — a typical climate zone 6 location where attic insulation depth has a direct and measurable impact on energy bills. Calculating how much blown-in insulation you need for a 1,500 sq ft attic involves understanding your current depth, your target R-value, and the settled depth per bag for the product you are using.

Question 4

Can blown-in insulation be installed in cathedral ceilings in New Brunswick homes? | Insulation IQ?

Accepted Answer

Cathedral ceilings are one of the most architecturally appealing — and thermally demanding — design features in a New Brunswick home. The combination of a finished ceiling surface directly below the roof deck, climate zone 6 cold, and New Brunswick's long heating season creates a challenging assembly where insulation choices and installation methods matter enormously.

Question 5

Is blown-in fibreglass better than cellulose for moisture resistance in Shediac NB? | Insulation IQ?

Accepted Answer

Shediac sits at the intersection of two moisture challenges: the high relative humidity of the Northumberland Strait coastline and the deep cold of a climate zone 6 winter. Choosing between blown-in fibreglass and cellulose for an attic or wall upgrade there is a genuinely nuanced decision, not a simple one-wins-all comparison.

What moisture resistance actually means for loose-fill insulation

When contractors or product salespeople say fibreglass is "more moisture resistant" than cellulose, th

Question 6

What are the advantages of dense-pack cellulose for older homes in New Brunswick? | Insulation IQ?

Accepted Answer

Dense-pack cellulose has become one of the most recommended retrofit insulation strategies for older New Brunswick homes, and for good reason. The combination of New Brunswick's cold Climate Zone 6 winters, the province's significant stock of pre-1980 housing in cities like Fredericton, Saint John, Moncton, and Campbellton, and the physical properties of dense-pack cellulose itself makes this an unusually well-matched solution.

What dense-pack cellulose actually is:
Cellulose insulation is manu

Question 7

How does blown-in insulation perform in the humid climate of coastal New Brunswick? | Insulation IQ?

Accepted Answer

Coastal New Brunswick presents one of the most demanding environments for building insulation in Atlantic Canada. Communities along the Northumberland Strait — Shediac, Moncton, Sackville — and the Bay of Fundy shoreline near Saint John experience elevated year-round humidity, marine air infiltration, and dramatic seasonal temperature swings. Understanding how blown-in insulation behaves in these conditions is essential before committing to any attic or wall upgrade.

Question 8

Does blown-in insulation attract mice or pests in New Brunswick? | Insulation IQ?

Accepted Answer

Pest attraction is one of the most common concerns New Brunswick homeowners raise about blown-in insulation, and the answer depends significantly on the material type and the condition of your building envelope. Understanding the difference between fiberglass and cellulose blown-in insulation — and what actually draws pests into attics and walls — helps put this question in the right context.

Fiberglass blown-in insulation does not attract mice or insects. Glass fibres have no organic content a

Question 9

Can I use blown-in insulation in my walls without removing drywall in Oromocto NB? | Insulation IQ?

Accepted Answer

Yes — blown-in insulation can be added to existing walls without removing the drywall, and this technique is well-suited to the older housing stock found throughout Oromocto and the surrounding Fredericton region. The method is called drill-and-fill, or more specifically dense-pack, and it is one of the most effective ways to improve the thermal and air-sealing performance of a home that was built with under-insulated or empty wall cavities.

Question 10

How long does it take to blow in attic insulation in a Quispamsis home? | Insulation IQ?

Accepted Answer

For most Quispamsis homes, blowing in attic insulation is a single-day job — and in many cases, a crew can complete the work in just a few hours. The actual timeline depends on the size of your attic, the target R-value, existing insulation levels, and whether any preparatory work is needed before blowing begins.

Typical time frames by house size:
- A small to mid-size bungalow (1,000–1,400 sq ft attic footprint): 2–4 hours
- A two-storey home with a 1,200–1,800 sq ft attic footprint: 3–5 hours

Question 11

Can blown-in insulation be added on top of existing attic insulation in Saint John? | Insulation IQ?

Accepted Answer

Yes — adding blown-in insulation on top of existing attic insulation is one of the most common and cost-effective retrofit upgrades for Saint John homeowners, and in most cases it's entirely feasible without removing or disturbing what's already there. The process is often called a top-up or attic insulation upgrade, and it's a standard service offered by insulation contractors throughout the greater Saint John area.

The first thing to assess before any top-up project is the condition of the ex

Question 12

Is blown-in insulation a fire hazard in New Brunswick homes? | Insulation IQ?

Accepted Answer

Blown-in insulation is not a fire hazard when it is properly installed using code-compliant materials — and in fact, certain blown-in products offer better fire resistance than some traditional batt insulation. However, there are important distinctions between the two main types used in New Brunswick homes: fiberglass and cellulose.

Fiberglass blown-in insulation is non-combustible. The glass fibres themselves will not ignite or sustain a flame, making this material inherently fire-safe. It car

Question 13

Does blown-in cellulose settle over time in New Brunswick homes? | Insulation IQ?

Accepted Answer

Yes, blown-in cellulose does settle over time — and in New Brunswick's climate, understanding how much settling to expect and how to account for it is important to ensuring your attic insulation performs as intended over its full service life.

The settling process is a function of gravity and gravity alone. Cellulose is made from densely processed recycled paper fibres that are ground into a light, fluffy mass. When installed at low density (as is typical for open attic blowing), the fibres are

Question 14

What is the R-value per inch for blown-in fibreglass vs cellulose in NB? | Insulation IQ?

Accepted Answer

Understanding R-value per inch is essential when comparing blown-in insulation options for a New Brunswick home, because the two most common loose-fill products — blown-in fibreglass and blown-in cellulose — perform very differently in terms of thermal resistance per unit of depth, and that difference directly affects how much material you need to buy and how much attic space the installation will consume.

Blown-in cellulose delivers approximately R-3.5 to R-3.8 per inch at typical installed de

Question 15

Can I rent a blowing machine and install loose-fill insulation myself in NB? | Insulation IQ?

Accepted Answer

Yes, you can rent a blowing machine and install loose-fill insulation yourself in New Brunswick — and for straightforward open attic situations, it's one of the more accessible DIY insulation projects available to homeowners. That said, there are important considerations around code compliance, vapour barriers, and rebate eligibility that you should understand before picking up the rental unit.

Most major building supply retailers and equipment rental companies in Moncton, Fredericton, and Sain

Question 16

How deep should blown-in insulation be in a Fredericton attic to meet code? | Insulation IQ?

Accepted Answer

Fredericton sits firmly in Climate Zone 6 under the National Building Code of Canada and National Energy Code for Buildings (NECB), and that classification drives the minimum thermal performance requirements for attic insulation in the city. For most residential attics, the target you need to meet is R-50 — and in many cases, upgrading beyond that minimum is cost-effective given how cold New Brunswick winters get.

In practical terms, R-50 translates to different depths depending on the type of

Question 17

Is blown-in cellulose or fibreglass better for attics in New Brunswick? | Insulation IQ?

Accepted Answer

Both blown-in cellulose and blown-in fibreglass are legitimate choices for New Brunswick attics, but when you weigh their respective strengths against the province's Climate Zone 6 conditions, most building-science professionals give cellulose a modest edge for the majority of residential applications. That said, the right choice depends on your specific attic geometry, existing moisture history, and budget — and either material can perform excellently when properly installed.

Question 18

How much does blown-in cellulose insulation cost in Moncton NB? | Insulation IQ?

Accepted Answer

Blown-in cellulose is one of the most cost-effective ways to increase attic insulation in the Greater Moncton area, and prices have remained relatively stable in the region over the past few years. For a typical Moncton home with an unobstructed attic, you can expect to pay $1,500–$3,500 for a blown cellulose upgrade, though the final number depends heavily on the existing R-value, the square footage, and the accessibility of the space.

To put that in more concrete terms: a 1,000 square foot at
