sierra pacific vs loewen windows - your pick?

I've installed both brands for clients, and honestly, they're both solid choices. Sierra Pacific tends to offer a bit more bang for your buck - good quality without breaking the bank. Loewen, though, has that premium feel and exceptional craftsmanship, especially if you're leaning toward wood windows. If budget's a factor, I'd probably lean Sierra Pacific; but if you're after that higher-end finish and don't mind spending a bit more, Loewen's worth considering. Either way, proper installation is key - don't skimp there.

"Either way, proper installation is key - don't skimp there."

Couldn't agree more with this point. I've seen top-tier windows perform poorly just because the installation was rushed or corners were cut. Personally, I've had great experiences with Loewen's wood windows - the craftsmanship really stands out, especially in historic or custom homes. But Sierra Pacific definitely holds its own, especially when budget constraints come into play. Good to see someone else highlighting the importance of installation quality... it really makes or breaks the project.

Good points on installation, but I'd argue that material choice and glazing options can be equally critical for energy performance. A few quick thoughts:

- Loewen's wood windows look fantastic, no doubt, but wood frames can require more maintenance and may not always offer the best insulation values compared to modern composites or fiberglass.
- Sierra Pacific has some solid aluminum-clad options, but aluminum can be a thermal bridge if not properly thermally broken - something to watch out for.
- Personally, I've had impressive results with fiberglass frames (like Marvin Essential or Inline Fiberglass). They offer excellent thermal performance, minimal expansion/contraction, and lower maintenance.
- Also, glazing matters a lot - triple-pane with low-E coatings and argon fill can significantly outperform standard double-pane setups, regardless of brand.

Installation quality is definitely crucial, but it's worth remembering that even the best install can't fully compensate for suboptimal materials or glazing choices. Just my two cents from an energy-efficiency perspective...
