Blown-in cellulose insulation is shredded recycled paper treated with borates against fire, mould and insects. Blown to the right density, this attic insulation tucks around wires and truss plates and forms a heavy, quiet layer.

Cellulose insulation carries more weight per inch than fiberglass. That weight also makes it harder for air to wander through, which helps in attics crowded with wiring and light boxes.

How Cellulose Insulation Goes In

Bales of cellulose insulation are broken up in a blowing machine on the truck, and a long hose snakes up to the hatch. We start at the far eaves and work back toward the opening, so nobody steps on finished cellulose insulation.

Rulers go up first. Cellulose insulation reaches R-60 at about 16 to 17 inches, and we blow slightly past that line to cover first-year settling.

Cellulose Insulation And Settling

All cellulose insulation sinks a little in its first year, often around a tenth of its height. The bag chart already allows for it, and your invoice lists the depth on the day it went in.

Cellulose Insulation After A Clean-Out

After a rodent clean-up, cellulose insulation is a sensible material to rebuild with, since its borate treatment discourages insects. Mice can still tunnel through cellulose insulation, so closing their entry gaps comes first, as our rodent damaged attic insulation removal page describes.

Cellulose Insulation Pricing

Most cellulose insulation jobs price out at $1.40 to $2.75 a square foot, and adding onto a clean layer sits at the bottom.

Related Attic Services

Most Vaughan attics end up needing two or three of these together.

  1. Grey blown cellulose piled deep on both sides of a plywood walkway between roof trusses

    Attic Insulation Top-Up

    An attic insulation top-up lays fresh blown fill over whatever clean layer is already there, lifting a thin attic to about R-60 in a single visit. It fits any attic whose existing insulation is still dry and free of droppings.

  2. Tan fiberglass batts between attic joists on each side of a plywood walkway leading to a gable vent

    Blown-In Fiberglass Insulation

    Blown-in fiberglass insulation is fluffy glass fibre carried by air down a hose until it drifts into every bay and corner. It weighs little, never soaks up water and brings a thin attic up to current levels fast.

  3. Worker in a white protective suit and respirator stuffing old pink batts into a black bag in an attic

    Rodent Damaged Attic Insulation Removal

    When mice, squirrels or raccoons have nested in the attic, we take out the fouled attic insulation, disinfect the bare joists and close the holes they used from inside. New insulation is installed only after that.

  4. Worker in a dust mask and gloves pressing a pink batt into a wall stud bay beside a window frame

    Attic Air Sealing

    Attic air sealing blocks the openings between the rooms below and the attic, so heated air stays in the house and the fill above can do its job. We seal pot lights, wire holes, plumbing vents and wall tops from the attic side.

  5. Pink fiberglass batts laid around a framed attic hatch opening in a finished attic floor

    Attic Hatch Insulation

    Attic hatch insulation seals and insulates the access panel in your ceiling. An unsealed hatch can let out more heat than a large stretch of insulated ceiling around it.

  6. Worker standing on a scaffold pressing a mineral wool batt between ceiling joists

    Cathedral Ceiling Insulation

    Cathedral ceiling insulation packs the thin rafter cavity above a sloped ceiling, where there is no attic floor to work on. The method depends on how deep the rafters are, how the roof vents and how we can get inside.

  7. White loose-fill insulation spread across an attic floor up to the bottom of the roof trusses

    Attic Insulation Rebate

    Through its Home Renovation Savings program, Ontario's gas and electricity utilities have offered an attic insulation rebate topping out at $1,250 for an attic finished at R-50. Here is what the program's own pages said when we read them, so you can plan with real figures.

  8. Pink batts between joists across a whole attic, with a round window in the gable wall

    Attic Insulation Cost

    Attic insulation cost for a detached Vaughan house usually falls between $1,500 and $5,000. Job type, floor area and the state of the old fill push yours up or down that scale.
