What Is an Insulated Glass Unit?

An insulated glass unit, or IGU, is two or three lites of glass held apart by a spacer, sealed around the edge and filled with an inert gas. It is the glass in almost every window, patio door and window wall built in the GTA in the last 40 years. When the seal fails, a lite cracks or the coating is wrong for the building, the unit is replaced as a whole. It cannot be taken apart and resealed on site.

IGU replacement is the specialist version of window glass replacement. It is about getting the spec exactly right, which matters most in condo towers and commercial buildings where every unit on the facade has to look the same.

Condo Spec Matching

Condo corporations in Harbourfront, CityPlace, Yonge-Sheppard and Mississauga City Centre often require replacement units to match the original exactly. A unit with the wrong coating shows up from the street as a different colour or reflection, and boards will reject it. A rejected unit means ordering and installing again, which often costs $5,000 or more across a few suites.

We avoid that by matching four things before we order:

  1. Fabricator and date from the spacer stamp.
  2. Overall unit thickness and each lite’s thickness by micrometer.
  3. Coating type and surface by spectrophotometer reading.
  4. Spacer colour and width by eye and measurement.

Signs a Unit Needs Replacing

  • Fog, haze or droplets between the panes
  • A crack in either lite
  • Visible coating damage or a mismatched replacement from a previous repair
  • Frost along the bottom edge in winter
  • A failed board or PM inspection

Bulk Programs for Buildings

Many towers built in the late 1990s and 2000s are now seeing seal failures across dozens of suites. We run building-wide programs: survey each suite, order units in batches, and schedule installs floor by floor so elevator bookings stay manageable. Each unit’s spec and warranty is recorded for the corporation’s files.

Send us the building address and the number of failed units, and our glass repair crew in Toronto will arrange a survey.

Straight Answers

What Actually Stops Toronto Homeowners From Booking IGU Replacement

Will the condo board approve a new unit?

In our opinion, the only safe answer is to match the original spec exactly. We read the spacer stamp, measure overall thickness and check the coating with a spectrophotometer, so the new unit passes the first walkthrough.

My building's glass is 20 years old. Can it still be matched?

Usually, yes. Many original coatings are still made or have direct equivalents from Cardinal, Pilkington and Guardian. We show the PM a sample comparison before ordering.

Who books the elevator and loading dock?

We do, with your property manager. WSIB clearance and a certificate of insurance go to management before the booking.

Can you do several suites at once?

Yes. Bulk orders for multiple suites or a building-wide program are scheduled floor by floor to keep elevator time down.

The 5-Step Precision Glazing Standard

How Does Our IGU Replacement Process Work?

Same five steps on every job, from a single pane to a curtain wall bay. Typical timeline: 7-14 business days.

  1. Step 1: Assessment & Safety Stabilization

    We inspect the failed units, check frames and drainage, and secure any cracked unit with film or a temporary panel.

  2. Step 2: Measurement

    Laser measurement of glass size, micrometer check of each lite and the overall thickness, spacer stamp read and spectrophotometer coating check.

  3. Step 3: Glass Sourcing

    Others order a generic clear unit and hope the board does not notice. We order IGMAC-certified Cardinal, Pilkington or Guardian units to the original spec.

  4. Step 4: Dry-Fit and Spec Match

    The crew compares the new unit's tint and reflectivity with neighbouring units, confirms coating surface and thickness, and checks setting block positions.

  5. Step 5: Install & Seal

    Unit set on new blocks, glazing tape or wet seal applied, stops refitted, and the warranties and spec sheet sent to the PM for the building file.

Toronto Buyers Ask

IGU Replacement FAQs

Can you match a 20-year-old condo spec for IGU replacement?

Yes. We match original Pilkington, Cardinal and Guardian coatings, tint, spacer width and overall unit thickness so the new unit passes condo board and PM walkthroughs. Matched IGUs run $380-$1,500 each. The process starts with the spacer stamp, which usually tells us the fabricator and date. Then we measure each lite and the overall thickness with a micrometer, and read the coating's reflectivity and tint with a spectrophotometer. If the exact product is still made, we order it. If not, we find the closest current equivalent and show the PM a sample against the existing glass before ordering. That is how a 1998 reflective Pilkington unit in Harbourfront gets replaced without a visible patch on the facade.

How much does IGU replacement cost in Toronto?

Insulated glass units cost $380-$1,500 each in Toronto, in CAD before HST. Residential Low-E Argon units up to about 12 sq ft run $380-$620. Condo suite units of 12-24 sq ft with coating matching are $620-$1,050. Large commercial or window wall units run $1,050-$1,500. Krypton fill or triple-pane adds $120-$320, and tempered or laminated lites add $90-$280.

What is the difference between Low-E on surface 2 and surface 3?

Surfaces are numbered from outside in. Surface 2 is the inside face of the outer lite, and surface 3 is the outside face of the inner lite. A solar control coating on surface 2 reflects summer heat before it enters, which suits towers with big south and west glass. A heat-retaining coating on surface 3 keeps winter heat in, which suits most houses. Matching the original surface matters for appearance too.

When is Krypton better than Argon?

Krypton insulates better in narrow gaps, so it is used in triple-pane units or where the sash only allows a thin unit. In a standard double-pane gap, Argon is the better value.

What does IGMAC certification mean?

IGMAC is the Canadian certification program for insulated glass units. Certified units are built and tested to CAN/CGSB standards for seal durability. Uncertified units may look the same but often fail far sooner.

How long does IGU replacement take?

Units are made to order in 7-14 business days. Installation is 30-90 minutes per unit, longer when elevator and suite access are involved.

Do you replace foggy units in houses too?

Yes. See foggy window repair and window glass replacement for residential units.

Can you replace curtain wall units?

Yes. Large exterior-glazed curtain wall bays are covered under commercial glass replacement.

Do you replace sealed glass in vehicles?

No. We do residential, commercial and storefront glass only. We do not repair or replace automotive glass or windshields.
