PERI systems compared head to head

Every pair of PERI systems in the ScaFix catalogue: which bay lengths and depths they share, which only one of them has, and what the planning engine counts for each on the same example house, parts group by parts group.

How do the PERI systems differ?

ScaFix has 2 PERI systems: PERI UP and PERI UP Easy. On the same example house (11.4 m × 5.3 m), PERI UP Easy needs 284 parts and PERI UP 605. Both offer the 3 m, 2.5 m, 2 m, 1.5 m bay lengths.

Pair by pair: bay lengths and depths

Each pair of PERI systems, from the catalogue the engine plans with. «Only in» lists the bay lengths one system has and the other lacks; the last column is the parts total of each on the example house.

Questions and answers

Can I mix parts from two PERI systems in ScaFix?

No. ScaFix plans each wall with one system’s own parts and never mixes systems in a parts list. Whether two systems of one maker may be combined on site is for PERI’s instructions to say. ScaFix is a planning aid, not a structural approval.

Why do the parts totals of the PERI systems differ?

A wall is filled with each system’s own bay lengths, so a shorter bay means more bays, standards and ledgers; the depth changes the transoms and decks, and frame systems count frames where modular systems count standards and ledgers. The totals say nothing about price or load class.
