Demsun P90 Thermcoat Insulation & Acoustic Foam 850ml

Demsun P90 Thermcoat is a single-component polyurethane spray foam insulation designed for thermal and acoustic applications in buildings. Applied with a standard applicator gun, it expands to fill cavities, gaps and irregular surfaces where traditional insulation materials simply cannot reach. The foam bonds to virtually all common building substrates and cures to form a continuous, seamless layer with a thermal conductivity of 0.025 W/(m.K), which puts it in the same performance bracket as premium rigid insulation boards.

Where this product earns its place is in situations where polystyrene boards, glass wool or rock wool are impractical. Think awkward roof spaces, pipe runs, window reveals, or any surface that is uneven, curved or structurally complex. The foam fills the profile of whatever surface it contacts, eliminating the thermal bridges and air gaps that rigid boards often leave behind. No cutting, no fixing clips, no waste off-cuts on the floor. One can, one gun, done.

Where Demsun P90 Thermcoat Spray Foam Insulation Gets Used

The foam is formulated for construction and refurbishment work where both heat retention and sound reduction are priorities. It performs well in new builds and retrofits alike, and its adhesion to masonry, timber, metal and concrete means it suits a wide range of structural elements without needing a primer or bonding agent on most surfaces.

Coverage is a practical consideration worth understanding before you start. Applied in a single layer at 1.5cm thickness from roughly 40cm away at a normal pace, one 850ml can yields approximately 3mu00b2. Thicker applications will naturally reduce coverage, so for deep-fill insulation jobs it is worth calculating your mu00b2 requirement before ordering. The foam does not require any mechanical fastening once cured and can be painted over once trimmed and set.

Acoustic and Thermal Performance in One Application

The monolithic application is what sets spray foam insulation apart from board-based systems. There are no joints or seams where cold air can track through, which is where a lot of traditional insulation loses efficiency over time. Demsun P90 eliminates those bridging points in a single pass. The acoustic benefit is a bonus for anyone insulating internal partitions, interfloor ceilings or plant rooms where airborne noise is an issue.

The formulation does not contain propellant gases harmful to the ozone layer, which is worth knowing if you are working on projects with environmental specification requirements. Once applied and trimmed, the surface accepts paint or plaster without additional preparation in most cases. It is also compatible with marine applications including boats and sea vehicles, where both weight and thermal performance matter.

Demsun P90 Thermcoat is a reliable, practical choice for spray foam insulation work across residential and commercial construction. It is well suited to tradespeople who need a product that performs consistently without fuss.
