K-FLEX® ST SHEET

K-FLEX® ST PÁS is suitable for all applications both civil and industrial that require the use of insulation material, without neglecting the price/quality relationship: refrigeration, air-conditioning, heating and plumbing, tanks, pipe fittings and water ducts.

K-FLEX® ST PÁS are ideal for sheet metal ducts and large size pipes. The height of 1000/1500 mm minimises segmentation of coating and simplifies installation, greatly reducing time and labour cost.

Available in standard and adhesive.

K-FLEX® ST DUCT

ECONOMICAL: flexible and easy to handle, it is made in measurements of 1500 mm in width to ensure easy installation on ducts.
PRACTICAL: the self-adhesive surface has been made rougher to improve its grip on the metal ducts.
CONVENIENT: its 1500 mm width cuts down on application time, reducing the final cost of pre-fabricated ducts.
FLEXIBLE: high elasticity helps attenuate vibrations that occur where there are joints and suspensions.

K-FLEX® KRAFT

K-FLEX® KRAFT has been specially produced to insulate ventilation and air-conditioning ducts in indoor environments. It is a modern replacement for mineral wool insulation.

 ECONOMIC: the self-adhesive strip reinforced with ALU foil is flexible and easy to use. It is produced in 1,500 mm widths in order to ensure easy installation on the ducts. Using K-FLEX KRAFT, it is possible to minimise the underhang of ductwork from ceiling structures. The lower weight of these materials provides financial savings on structural supports.
PRACTICAL: the self-adhesive surface has been roughened to improve its adhesion to metal ducts, without the need for spikes or other tools. No dusting of fibres takes place as is the case with mineral wools.
COMFORTABLE: easy installation at the place of assembly, makes it possible to pre-insulate air ducts.
FLEXIBLE: Applying self-adhesive panels directly to the AC ductwork minimises vibrations throughout the HVAC system and improves overall acoustic comfort.

SPECIAL THINNER FOR K-FLEX® ADHESIVES

Before covering the surfaces to be insulated, it is advisable to clean them with the special K-FLEX® thinners which, thanks to its composition, is also suitable for use with K 414, K 420 or K 425 adhesives. Cleaning of all surfaces with the special K-FLEX® thinners also improves the performance of the adhesives.The special K-FLEX® thinners can be also used for cleaning brushes and spatulas used to spread the glue. Available in 1 litre tins.
