Knowledge base · The reference library
This is the homeowner's reference library I wish existed when I started this work. Plain-language explanations of how the technology works, how the installation is done properly, what the real costs are, and what to look for in the quotes you receive. No catalogues. No sales decks. Just the answers that matter when the decision is yours.
How European windows go into a Calgary home. The install method decides 70% of the performance — and most quotes describe the window without describing the install.
The engineering behind REHAU profile systems and GU hardware — what's actually different about the European spec versus what you'd find in a builder showroom.
Cross-section diagrams of REHAU Synego & Artevo windows, REHAU entry door, aluminum window profile, and 5-panel carbon-fibre reinforced door — chamber by chamber, seal by seal.
Brilliant Design / Synego / Artevo tiers, RAU-FIPRO composite reinforcement, the compression-seal mechanics, and the GU multi-point lock that makes the system work.
Steel-reinforced slabs, multi-point locking with 5-8 hardened bolts, EPDM compression seal, and high-performance glazing — the door specification homeowners ask for when the front door has to last 30+ years.
Six technical differences — seal mechanism, frame depth, glazing spacer, hardware multipoint, drainage detail, install method — and what they cost you to ignore.
How the screens mount when the sash swings inward, the child-safety restrictor at 6cm, AB Building Code §9.7 egress compliance, and the questions buyers ask before they trust the system.
What the common window failures actually mean — and the honest call on whether to repair, reglaze, or replace.
Real Calgary numbers, honest ranges, what drives them up or down, and what a "quote" should actually include.
Age is not a fault. The five findings that mean a window is genuinely finished, the four that look like failure but usually aren't, a symptom-by-symptom table, and a three-minute check you can run on every window yourself.
Per-opening range by tier, full-house range, what drives costs up (heritage, stucco, custom shapes, acreage access), what drives them down (production builder homes, simple ground-floor access), staged-retrofit math.
Yes, and the thermometer matters less than you think. One opening at a time, why the foams and sealants are the real constraint, why a cold day is the best time to catch a bad seal, and when I'd tell you to wait for spring.
One warranty is really four separate promises — frame, sealed glass unit, hardware and labour — each with its own clock. Where the gaps sit, what voids coverage, and the seven questions to put to every quote in writing.
Water on the inside of the glass is usually your air, not a broken window. How to read the location — outside face, centre of the glass, the edges and frame, or sealed between the panes — and which of the four actually costs you money.
The City of Calgary's rule in its own words: no permit for a like-for-like swap, a building permit for a new or enlarged opening. Plus the type/operation condition most homeowners skim past, and the bedroom egress requirement that applies either way.
You don't have to do the whole house. Why replacing the one window that bothers you most is often the smartest first move, when all-at-once genuinely wins, and how a phased retrofit actually works.
12-page downloadable guide: what to look for in quotes, how to compare installers, REHAU tier selection, install red flags, the questions worth asking.
Twelve scenarios drawn from real Calgary install reports — what failure looks like, and what the engineering does to fix it.
The cold halo around the favourite chair. The black mould spot that keeps coming back. The bedroom no one can sleep in. The whistle at 40 km/h. 12 scenarios with problem, agitation, and what fixes them.
Why most window projects that start staged finish full-house within a year or two — and the honest math on when staged is the right call and when it's a way of postponing the real fix.
Nine recent installs across inner-city heritage, acreage builds, and commercial work — with photos, scope, and the story behind what got specified and why.
