HVAC Tapes by Tuftape

Quick answer

Which tapes are used to seal HVAC ducts?

HVAC ducts are sealed with three tapes: FSK (foil scrim kraft) tape for insulation joints, aluminium foil tape for vapour sealing and heat reflection, and cloth duct tape for bundling and air sealing. Tuftape manufactures all three in Dubai, with service ranges from -30 °C to +95 °C for the foil grades.

HVAC systems need pressure-sensitive adhesive tapes with specific properties. Tuftape’s HVAC series is built to meet code and quality requirements for contractors and industry professionals, and we have made it since 2010.

The range

Foil Scrim Kraft (FSK) tape

Foil Scrim Kraft (FSK) tape

Seals insulation joints and seams against moisture and vapour on 3-way scrim FSK jacketing and fibreglass duct board. Fibreglass scrim reinforces the aluminium foil in three directions. A rubber adhesive stays effective in cold weather and conforms to irregular surfaces.

Aluminium foil tape

Aluminium foil tape

Professional-grade tape with dead soft aluminium foil and a solvent acrylic adhesive. HVAC uses include vapour sealing in ducting, thermal conductivity, moisture and chemical resistance, and heat and light reflection. It also suits other permanent sealing, holding, splicing or masking jobs that need a foil backing.

Duct tape

Duct tape

Used in HVAC, plumbing and general contracting for heavy bundling, wrapping and air sealing, including metal sheets and air gaps in air-conditioning systems. Three layers: a moisture-resistant polyethylene film, a mesh cloth that tears easily yet gives high tensile strength, and a natural rubber hot-melt adhesive that grips regular and irregular surfaces.

Quick answers

HVAC Tapes: common questions

What is FSK tape?+

FSK stands for foil scrim kraft. The tape has an aluminium foil face reinforced with fibreglass scrim and is used to seal joints and seams of FSK insulation jacketing and fibreglass duct board against moisture and vapour.

Foil tape or duct tape for ductwork?+

Use aluminium foil tape for permanent vapour-sealed duct joints and heat reflection, and cloth duct tape for bundling, wrapping and general air sealing.

What temperature can aluminium foil tape take?+

Service temperature is −30 to +95 °C, and it should be applied between +10 and +40 °C.
