Specifier's Guide & Design Guide for Legalett GEO-Slab Frost Protected Shallow Foundations & Air Heated Radiant Heated Floor Systems - ONReference & Technical Materials - Specifier's Guide

 

  • Legalett is a building system.
  • Legalett follows the building process from design to installation.
  • In contrast to other heated floor systems, we design both the Foundation and the Air-Heated Radiant Floor System as a whole. The migration of dampness and the effects of frost heave are eliminated through proper design.
  • Due to the unique ability of the Legalett System to eliminate frost walls, construction time and costs are reduced.
  • Legalett is suitable for detached houses, row houses, townhouses, pre-schools and nursery schools, assembly buildings, industrial buildings – indeed for almost all types of heated floors and foundations.
  • Legalett can be easily adapted for continuous and semi-continuous permafrost areas.
  • The Legalett system includes coordinated design of the Foundation and Air-Heated Radiant Floor System
