With an R value of R-7.4/inch, Heatlok HFO Pro, applied 1.25" (32 mm) thick, provides R-7.5 insulation under the entire surface of the slab, exceeding Building Code require- ments. Due to its high compression stength (35 psi), Heatlok HFO Pro can be sprayed directly on crushed stone and provides continuous insulation with no joints.

Heatlok HFO, used under the slab, on the foundation walls and on the rim joists, provides a continuous, seamless, air-tight, from the insulation below the basement slab right up to the ground floor. Thermal Break The NBC now requires a thermal break between the foundation wall and the slab (minimum value of R-4). The continuity of the polyurethane foam between the slab and the wall surface creates the thermal break by itself. Insulation Performance With 1,25" (32 mm) below the slab (R-7.5)and 2' (64 mm) on the foundation walls, the required minimum values of R-5 below the slab and R-17 are exceeded: R-17.5 for the full wall assembly assembly without any thermal bridge. Price-Quality Ratio Another benefit of insulating the basement in a single step, namely application below the slab, on the foundation wall and on the rim joists, is the cost savings. Application is very quick and the product cost will be lower per square foot, since the applicator's travel time and prep are offset by the volume to install, compared with a conventional insulation system that involves multiple steps, several materials, plus more labour, which leaves more room for error. When a similar installation is done with the use of insulation panel + polyethylene + sealant + glue and tape the overall performance and the quality of the job depends of the level of workmanship. In a single step with Heatlok HFO, we create a durable and perfectly sealed structural envelope during and after the work. All plumbing pipes and vents, sumps and drains in the slab and walls are sealed in one operation,without any complication regarding compatibility of materials. Adhesion to the concrete wall is perfect; there is no possible air space for condensation and mold to penetrate. Heatlok HFO delivers an insulation and moisture control system, and a vapor barrier, all in one step, quickly and effectively. The durability, adhesion and quality of the product are confirmed by a CMHC study, with everything remaining intact in the long term. Resistance to Radon Gas In addition, Heatlok HFO has been tested for its resistance to radon gas by recognized independent labo- ratories. Tests consisted in comparing Heatlok HFO's performance with a 6-mil polyethylene sheet. 6 ,, ,, yr . ,_�L.A43 rl � ,.
