SolvEx

SolvEx — The Most Thorough Certified Solution Finder

We did not bolt EN 1366 onto a search box. We built a rule engine from the ground up so the certified fire stopping system you select can move into quality control, inspection documentation, and audit-ready reporting without losing context.

How it works

Three steps from scenario to certified match

01
Describe

Describe your scenario

Penetrant, substrate, fire class, annular space, and environment. Structured inputs, no free-text guessing.

02
Evaluate

Engine evaluates EN 1366 rules

Clauses are checked against certified systems, margins are computed, and edge cases are flagged before you decide.

03
Match

Get your certified match

Ranked results with reasoning, certificate references, installer datasheets, video support, and the data needed to plan quality control on site.

Explainability

Every match shows its reasoning, clause by clause

Auditors do not accept 'the system said so'. SolvEx shows which clauses passed, the margin on each, and the certificate references behind every assertion.

  • Per-clause pass and fail states with numeric margins
  • Direct citation to ETA, EAD, and manufacturer datasheets
  • Tight-margin alerts so your team knows what is close to the limit

REVIEW
Always current

One source of truth, synced from the manufacturers themselves

Certificates expire, systems get withdrawn, and manufacturers publish revisions. SolvEx tracks those changes so the system you spec today is still certified tomorrow.

  • Live sync with manufacturer certification feeds
  • Automatic withdrawal alerts on past projects
  • Version-pinned references so old reports still resolve

Why BYLT

No other solution finder matches our depth. Built from the ground up on EN 1366.

Most finders are filtered catalogues with EN labels stamped on top. Ours encodes the clauses themselves, checks all of them every time, and carries the result into BYLT's connected compliance workflow.
