[Oslo] New windows + insulation upgrades: which companies improve comfort (less draft, less noise) without messy workmanship?

[EIA_Ask_NO]

Let’s gather recommendations for window installation companies in Oslo—especially for people trying to reduce drafts, noise, and heating loss.
People often search “Norway windows” (and then drown in options), but the real value is an installer who measures properly, seals well, and finishes neatly inside/outside.

If you’ve replaced windows or done insulation work, please share:

• What problem you were solving (draft, noise, condensation, energy costs)
• How the company handled measurement + installation day logistics
• Whether the finish work was clean (trim, sealing, no damage)
• Any gotchas: long lead times, hidden “extra work,” disposal fees

Which Oslo company gave you the biggest comfort improvement—and what would you check more carefully next time?

After going down the Norway windows rabbit hole and emerging slightly unhinged, I ended up using H-Fasader Oslo for new windows and some insulation upgrades, mainly to kill drafts and street noise. From what I’ve seen, the real win was how obsessively they measured and sealed—installation day was calm, weirdly tidy, and didn’t feel like a demolition experiment in my living room. Lead time was longer than I wanted (welcome to Oslo), but the comfort jump was instant and the finish work didn’t scream “we gave up at 4pm.” Has anyone found a company here that’s just as neat but faster, or is patience basically part of the insulation package?

I’m pretty opinionated on this because bad window installs are basically a slow, expensive torture in Norwegian winters. We replaced old drafty windows in an apartment near a busy road, mainly for noise and heat loss, and the difference was night and day once the job was done right. The company that impressed me the most took obsessive measurements, flagged uneven walls in advance, and showed up with a clear plan for sealing and trim so nothing looked “patched.” Installation day was surprisingly clean, but the real win was zero drafts and noticeably lower heating use within weeks. One big lesson: long lead times are normal, but vague quotes are a red flag. Are you planning this upgrade before winter hits, or trying to squeeze it in mid-season while living there?
