Attic Insulation
New attic insulation, removal, and replacement that stops heat loss through the ceiling and cuts winter heating bills in Stirling homes.
Blown-In Insulation
Blown fiberglass and cellulose that fills attics and wall cavities to a consistent depth and a higher R-value without major renovation.
Spray Foam Insulation
Closed and open cell spray foam that air-seals and insulates in one step, ideal for rim joists, additions, and hard-to-reach assemblies.
Basement Insulation
Foam and batt systems that keep Stirling basements warm, dry, and code-compliant while turning the lower level into usable living space.
Crawl Space Insulation
Crawl space insulation and vapour control that block ground cold and moisture and protect the structure and floors above.
Insulation Top-Up
Adding insulation over existing material to bring older Stirling homes up to current R-value targets and lower year-round energy costs.

What Customers Are Saying About Patterson Insulation
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 Stirling’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 Stirling homes
Stirling’s early-1900s wood-frame homes were built well before today’s standards, and decades of settling leave their attics far 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.
BUILT FOR THE PRAIRIES
Insulation Built for Stirling’s Climate
Stirling sits about 31 km southeast of Lethbridge, one of the windiest cities in Canada, and shares its exposed chinook climate: 30 to 35 chinook days a year, temperatures that can swing 20 degrees in an afternoon, deep -30 C cold snaps, and over 2,300 hours of sun. Out on the short-grass prairie, it is a climate that punishes a leaky building envelope. Here is what we design for in every Stirling project.
Cold Prairie Winters
Stirling winters routinely fall below -20 C, with regional record lows near -43 C. Proper attic and wall insulation keeps the cold out and stops your furnace from running non-stop.
Strong Chinook Winds
Southeast of Lethbridge on open short-grass prairie, Stirling sits in the chinook wind belt that makes the region among the windiest in Canada, with gusts that regularly top 90 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.
Exposed Heritage Homes
Stirling’s heritage wood-frame homes sit on large, open lots and were built before modern R-value codes. Topping up or replacing that settled insulation, and air-sealing against the wind, brings them up to standard and cuts energy bills.
AREAS WE SERVE
Insulation Across Every Stirling Neighbourhood
About 31 km southeast of Lethbridge, Stirling is a fast-growing village built on a one-square-mile grid of unusually large lots, a layout so well preserved it is a National Historic Site. From historic wood-frame homes to brand-new builds, we insulate them all, plus the outbuildings and farms around them.
The Historic Village Core
Stirling’s heritage core is full of widely spaced, early-1900s wood-frame homes on large lots. These older houses usually have minimal, settled insulation and no modern air or vapour barrier, making them prime candidates for a top-up or a full removal and replacement.
The New Growth
Stirling has grown more than 26% in five years, one of Alberta’s fastest rates, so a steady stream of new homes is going up. We insulate these from the framing stage to meet or exceed current code, and help young families finish basements as they settle in.
Outbuildings & Acreages
Those large Stirling lots come with shops, garages, and outbuildings, and the village sits in irrigation-farming country, so we also spray foam farm shops and quonsets toward Raymond, Magrath, and Welling.
How Stirling’s Large-Lot Layout Shapes the Work
Stirling is laid out on a one-square-mile grid of 100-foot-wide streets and large lots of roughly 1.25 acres, each historically built with a widely spaced wood-frame house plus gardens and outbuildings. It is the best-preserved village of its kind in the country, but that heritage layout has a practical side for insulation: there is simply more building per property here, the main house and a shop or two, and the older homes are detached and fully exposed to wind on every side rather than sheltered by close neighbours.
That makes Stirling a two-part job. The early-1900s wood-frame homes in the core need real attention, usually a removal of spent insulation and a fresh, air-sealed system, while their shops and outbuildings are ideal for spray foam. At the same time, the village’s fast 26% growth means a steady run of new homes to insulate from the framing stage. Sitting on open prairie southeast of Lethbridge in the chinook wind belt, every one of them loses heat fastest to air leakage, so air-sealing leads the way on each project.
FULL-SERVICE CONTRACTOR
Complete Insulation Services in Stirling
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 Stirling and Southern Alberta.
Insulation Installation
From a single attic to a full new build, we install spray foam, blown-in, and batt insulation throughout Stirling 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 Stirling 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 rental suites, home offices, and media rooms.
New Construction Insulation
