What Customers Are Saying About Patterson Insulation
FULL-SERVICE CONTRACTOR
Complete Insulation Services in Lethbridge
Patterson Insulation is a full-service insulation contractor, not just an installer. From the first assessment to removal, installation, air sealing, and the finishing details that make insulation actually perform, we handle the whole building envelope for homes, acreages, and commercial buildings across Lethbridge and Southern Alberta.
Insulation Installation
From a single attic to a full new build, we install spray foam, blown-in, and batt insulation throughout Lethbridge homes and commercial buildings. Every installation starts with the right R-value for the assembly and finishes with a tidy, code-compliant result that keeps heat where it belongs through the coldest prairie winters.
Insulation Removal
Old, settled, water-damaged, or rodent-contaminated insulation does more harm than good. We safely vacuum out and dispose of failed attic and wall insulation, sanitize the space, and prepare it for a fresh, high-performance system. It is a common first step in older south-side and north-side Lethbridge homes.
Insulation Repair & Top-Up
Insulation that has compressed, shifted, or been disturbed by trades or wildlife leaves cold spots and rising bills. We repair damaged sections and top up under-insulated attics to current R-value targets, restoring even temperatures without a full tear-out.
Air Sealing & Draft-Proofing
In Canada’s windiest city, air leakage is often a bigger problem than missing insulation. We seal gaps around top plates, attic hatches, pot lights, plumbing stacks, and rim joists so chinook winds stop driving drafts and dust through your home.
Attic Ventilation & Baffles
Insulation only performs when the attic can breathe. We install baffles and balance intake and exhaust ventilation so moisture dries out, summer heat escapes, and you avoid the frost build-up and ice damming that follow a warm, poorly vented attic.
Vapour Barrier & Moisture Control
The Alberta Building Code requires a sealed vapour barrier for good reason. We install and repair vapour barriers and use closed-cell spray foam where moisture resistance matters most, protecting framing and drywall from the condensation that forms when warm indoor air meets surfaces at -30 C.
Soundproofing Insulation
Insulation is not only about temperature. We add acoustic batt and spray foam to interior walls, floors, and shared assemblies to cut noise between rooms, levels, and suites. It is popular in West Lethbridge rentals near the University and in home offices and media rooms.
New Construction Insulation
Building or renovating in Lethbridge? We work from the plans and the framing stage to insulate walls, basements, and attics to meet or exceed National Building Code – Alberta Edition requirements, coordinating with your schedule so inspections pass the first time.
Free Energy Assessment
Not sure where your home is losing heat? We inspect your insulation, air sealing, and ventilation, measure existing R-values, and use thermal imaging to pinpoint exactly where energy escapes, then give you a clear written quote with no obligation.
BUILT FOR THE PRAIRIES
Insulation Built for Lethbridge’s Climate
Lethbridge is the windiest city in Canada and sees 30 to 35 chinook days a year, with temperatures that can swing 20 degrees in a single afternoon. Add deep -30 C cold snaps and 2,300 hours of sun a year, and you have a climate that punishes a leaky building envelope. Here is what we design for in every Lethbridge project.
Cold Prairie Winters
Lethbridge winters routinely fall below -20 C, and the record low is -42.8 C. Proper attic and wall insulation keeps the cold out and stops your furnace from running non-stop.
Strong Chinook Winds
Lethbridge records more high-wind days than almost any city in Canada, with gusts that have hit 171 km/h. Air sealing and spray foam stop the wind-driven drafts that loose-fill insulation alone cannot block.
Big Temperature Swings
Chinooks can swing temperatures more than 20 degrees in a day. A sealed building envelope keeps indoor comfort steady through rapid freeze-thaw cycles.
Hot, Dry Summers
Summer highs push past 30C. The same insulation that holds heat in winter keeps upper floors cool and lowers air conditioning costs.
Older Housing Stock
Many Lethbridge homes were built before modern R-value codes. Topping up or replacing insulation brings them up to standard and cuts energy bills.
R-VALUE & CODE
Insulation, R-Value, and the Alberta Building Code
R-value measures how well insulation resists heat flow: the higher the number, the slower heat escapes in winter and creeps in during summer. In Lethbridge’s climate, hitting the right R-value is the difference between a furnace that cycles comfortably and one that runs all day. Here is what current code expects, and what it means for your home.
What current Alberta code calls for
The National Building Code – Alberta Edition (Section 9.36) sets minimum insulation levels for new and renovated homes:
Attics & ceilings: roughly R-50 to R-60 (RSI 8.67 to 10.43)
Above-grade walls: about R-22 (RSI 3.08) in the cavity
Basements & foundations: insulated to code for below-grade walls
Plus: a sealed vapour barrier and proper attic ventilation are both required
These are minimums. In a climate like ours, exceeding them where it is practical pays for itself in comfort and energy savings.
What it means for older Lethbridge homes
Many homes on the north and south sides were built before these standards, and decades of settling leave attics well below R-50. That gap is exactly where heat escapes and where chinook-driven air leakage does the most damage.
The good news: topping up an attic from R-20 to R-60 is one of the most cost-effective upgrades a homeowner can make, and it rarely requires renovation. We measure your existing R-value during a free assessment, tell you exactly where you stand against code, and recommend the right combination of spray foam air sealing and loose-fill to get you there.

Insulation Contractors Lethbridge: What Gets Checked Before the Quote
Most jobs start in the attic hatch or the mechanical room. Kirk Patterson looks at the existing insulation depth, the condition of the vapour barrier, whether the eaves are packed or wind washed, and whether bath and range fans actually vent outside instead of dumping moist air into the attic. In basements and crawl spaces, the rim joist cavities, the sill plate and any cold corners behind finished walls get a look. That on-site consultation is where scope is set: top up, remove and replace, air seal first, or a mix across different parts of the house.
The quote spells out the material, the areas covered and the sequence of work, so you can compare it fairly against other insulation contractors in Lethbridge before deciding anything.
Blown-In Insulation Lethbridge Attics and Walls: Fiberglass or Cellulose
For blown-in insulation Lethbridge attics and older walls are the usual jobs, because loose fill flows around trusses, wiring and odd framing that batts cannot fit tightly. Loose fill fiberglass stays light and does not settle much, which suits deep attic top-ups over an existing layer. Cellulose is denser, packs well into closed wall cavities and slows air movement through the fill, which helps on older homes with drafty stud bays.
The material is fed from a machine at the truck through hose runs to the work area. Before blowing, we baffle the soffits so ventilation is not buried, mark depth so coverage stays even across the attic, and seal the hatch. For walls, cavities are filled through access holes and the openings are patched. Hoses and equipment come out the way they came in, and the work area is vacuumed.
Attic Insulation Lethbridge: Air Seal First, Then Add Depth
Adding depth over leaky ceilings wastes material. On attic insulation Lethbridge projects we seal the openings that let warm indoor air escape upward first: top plates, plumbing and wiring penetrations, chimney chases, pot light housings and the attic hatch. Once those are sealed and any bath fan ducting is routed to the exterior, the new layer goes on to a consistent depth that meets current code requirements for the assembly.
If the existing insulation is water stained, rodent damaged or full of construction debris, it comes out by vacuum before anything new goes in. Baffles are installed at the eaves so soffit airflow keeps the deck cold in winter, which is how you avoid ice damming and frost buildup on the underside of the sheathing.
Spray Foam Lethbridge Projects: Open Cell and Closed Cell Uses
Spray foam Lethbridge jobs usually fall into two groups. Closed cell foam goes where you need air sealing, high R per inch and moisture resistance in one step: rim joists, crawl space walls, basement foundation walls, steel buildings, quonsets and agricultural structures. Open cell foam is softer and more often used inside interior walls and ceilings where sound control and a full cavity fill matter more than moisture performance.
Foam is applied in controlled lifts rather than one thick pass, so it cures properly and bonds to the substrate. Surfaces are cleaned and dry before spraying, adjacent finishes are masked, and the building is ventilated during and after application. Where an exposed application needs a thermal or fire barrier, fireproofing spray can be applied over the foam.
