A Comparison We're Uniquely Positioned to Referee
Our company is literally named Wood Windows — and most of what we install today is vinyl and fiberglass. That's not irony; it's the market being sensible, and us with it. Wood and vinyl aren't competitors so much as answers to different questions, and after 46 years of installing both we can draw the line between those questions cleanly.
The Case for Each, Without Romance
Vinyl is the rational default. For the great majority of Treasure Valley homes — production builds whose original windows are fogging out — a quality vinyl line like the Milgard Tuscany hits every number that matters (U ≤ 0.30, lifetime warranty, zero maintenance) at a price that does the whole house. It's not the cheap choice; it's the correct engineering for the assignment.
Wood is the specific answer. Three assignments call for it. Character architecture: craftsman, Victorian, farmhouse, mid-century — profiles and proportions vinyl extrusions can't honestly imitate. Historic review: Boise's North End and East End effectively require wood-family windows on visible elevations; this is where clad-wood exists. Interiors that lead: stained trim, mountain-house warmth, the tactile difference no laminate reproduces.
The Maintenance Question, Retired
The old objection — "wood means painting forever" — describes windows nobody manufactures anymore as mainstream product. The Andersen 400 has worn no-paint Perma-Shield cladding since 1966; Marvin and Kolbe clad in architectural-finish aluminum. Exterior maintenance on modern clad-wood is a hose. The interior pine gets finished once, on your schedule, in your color.
Where the Money Argument Lands
Vinyl wins the spreadsheet; wood wins specific houses. Our quoting habit reflects it: on character homes we bring both numbers and let you see what the premium buys in profile and interior; on standard replacements we don't waste your time upselling material the architecture can't use. And the popular compromise — clad-wood facing the street, vinyl on the sides and rear — gets quoted more seasons than not.
Both materials, one measure, honest numbers: (208) 376-2200.
Frequently Asked Questions
Are wood windows worth it over vinyl?
For the right house, decisively — and for the wrong one, not at all. Clad-wood earns its 70–100% premium on character homes, historic districts, stained-trim interiors, and forever-home horizons. On a standard subdivision replacement, quality vinyl delivers the same energy numbers for a fraction, and we'll say so.
Do wood windows still require constant painting?
Modern ones don't — that problem was solved by cladding. Today's 'wood windows' (Andersen 400, Marvin, Kolbe) wrap the exterior in vinyl or aluminum cladding that never needs paint; only the interior wood is yours to finish, once. Bare-exterior wood windows are now mostly a restoration specialty item.
Which insulates better, wood or vinyl?
Functionally a tie. Wood is a fine natural insulator and multi-chamber vinyl traps air well; both families test U 0.25–0.31 with the same Low-E glass doing most of the work. Nobody should pick between these materials on U-factor.
Can I put vinyl windows in a historic Boise home?
Often not where they're visible — North End and East End design review generally rejects vinyl profiles on street-facing elevations of contributing homes. Clad-wood exists largely for this assignment: authentic profiles outside, modern glass inside, approvals granted.
