Why would we insulate Concrete Slabs?
Insulating concrete slabs—under-slab in carparks and on-grade or suspended in buildings—cuts heat loss by up to 80 %, stops cold floors, slashes heating costs and delivers rapid payback in any heated or air-conditioned space.
Slab insulation prevents condensation under membrane floors, eliminates thermal bridging through stems and columns, protects waterproofing from freeze-thaw damage and extends the life of the entire structure in cold and temperate climates.

Massive reduction in heating energy
Under-slab and perimeter insulation reduces ground heat loss by 60–80 %, often cutting winter heating bills 20–40 % in parking garages, warehouses and offices built over unheated or exterior slabs.
Warm + comfortable floors, always
Insulated slabs keep surface temperatures 8–15 ° warmer in winter, eliminating cold feet in retail showrooms, offices and residential units while preventing condensation on polished concrete or tiled floors.
Condensation and freeze-thaw stop
Insulation keeps the slab above dew point, stops moisture condensation that destroys coatings and toppings, and prevents spalling and rebar corrosion from winter salt and freeze-thaw cycles in exposed carparks.

Faq
Soil conducts heat 10–20 times faster than proper XPS insulation; uninsulated slabs lose massive energy to the ground in winter and stay cold all season.
High-compressive-strength XPS (60–100 psi) is specifically rated for carpark loads; millions of square metres in parking garages worldwide prove it lasts decades without compression failure.
Perimeter-only saves only 20–30 % of heat loss. Full under-slab insulation plus perimeter delivers 70–80 % savings and eliminates cold floors throughout the entire space.
