Here you will find all of the GEO-Slab Frost Protected Shallow Foundation & Air-Heated Radiant Floor Heating technical and reference materials as found in our Specifier's Guide for Architects and Design Professionals.

 

​Reference & 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
