Is glue-down LVT better than floating LVP for a Vancouver condo with in-floor heating?

Glue-down LVT is generally the better choice for a Vancouver condo with in-floor radiant heating, and most radiant system manufacturers recommend it over floating installation. The full-spread adhesive creates direct thermal contact between the heating element, subfloor, and flooring surface — which means heat transfers more efficiently and evenly into your living space.

Here is why this matters. A floating click-lock LVP floor sits on top of an underlayment with a small air gap beneath each plank. That air gap acts as a thermal insulator, reducing heat transfer efficiency by an estimated 10 to 20 percent compared to glue-down. In a Vancouver condo where you are paying to run that radiant system through our cool, damp months from October through April, that efficiency loss translates to higher energy costs and a floor that never feels quite as warm as you expected. Glue-down LVT bonds directly to the subfloor with no air gap, allowing heat to conduct straight through the adhesive and into the vinyl surface. The result is a warmer floor at lower thermostat settings.

That said, not every glue-down adhesive works with radiant heat. Standard vinyl flooring adhesive can soften, lose grip, or off-gas at elevated temperatures. You must use an adhesive specifically rated for radiant heat applications — check both the flooring manufacturer's and adhesive manufacturer's specifications for maximum temperature compatibility. Most radiant systems under vinyl flooring should not exceed 85°F (29°C) surface temperature, and both the LVT product and adhesive must be rated for at least that threshold.

For hydronic (water-based) radiant heating — common in newer Vancouver condo builds — glue-down LVT over concrete is the ideal combination. The concrete slab acts as a thermal mass that stores and gradually releases heat, and the glue-down LVT transfers that warmth efficiently. For electric radiant mat systems, the LVT should be installed over the mat using a modified thinset or self-levelling compound as an embedding layer, with the glue-down LVT adhesive applied on top. This requires precise installation — it is not a DIY project.

Strata Considerations

In a Vancouver condo, there is an important wrinkle: strata acoustic requirements. Most strata buildings require STC 55+ and IIC 55+ ratings for floor assemblies. Glue-down LVT over concrete with radiant heat may not meet these standards without an acoustic membrane between the concrete and the LVT. Products like Schluter DITRA-HEAT serve double duty as both an uncoupling membrane for the electric heating cables and an acoustic layer — but you need to verify that the full assembly (concrete + membrane + heating + LVT) achieves your strata's required STC/IIC ratings. Get this confirmed in writing before purchasing.

Also note that Technical Safety BC requires an electrical permit and inspection for hardwired electric radiant floor heating systems. A TSBC-certified electrician must handle the electrical connections. Hydronic systems connected to existing boilers may also require permits depending on the scope of work.

Cost-wise, glue-down LVT installation runs $6 to $12 per square foot installed in Metro Vancouver — roughly $1 to $3 more per square foot than floating LVP due to the adhesive cost and more labour-intensive installation process. For a 500 sq ft condo, that is an additional $500 to $1,500, but the improved heating efficiency and superior feel underfoot justify the investment in a radiant heat application.

If you are planning a condo flooring project with radiant heat, getting the product selection, adhesive, and acoustic assembly right from the start is critical.
