Why Irvtec exists

Most product research online is either a wall of dense specs or a page dressed up as advice that’s really just trying to sell you something. Irvtec exists to sit in between: quick, practical tools that give you a straight answer based on your own situation, not a generic sales page.

We’re a small, independent site — not owned by a manufacturer, retailer, or installer, and not a large media company either. That keeps things simple: we build tools we’d actually want to use ourselves, and we’re upfront about how the site makes money to keep them free.

How we work

A few things that guide every tool and guide we publish.

Independent by design

We’re not tied to any single brand or provider, so a tool’s result isn’t shaped by who’s paying us the most.

Practical over perfect

Our tools give you a solid starting point in seconds, not a 40-page report. Fast beats exhaustive when you’re just trying to decide.

Upfront about funding

Some links earn us a commission — it never changes what we recommend, and it’s explained in full on our Legal page.

Worth knowing before you rely on a result

Our calculators and checkers are built to give you a useful estimate, not a guaranteed final figure — always worth double-checking anything with real money attached directly with a provider.

Full details on how that works, plus our affiliate disclosure and privacy policy, are on our Legal page.
