## Summary description

THERMAFLEX Kolano is a pipe insulation elbow made from high-quality PE foam with dimensions 42/9 (DWZ). Designed to insulate and protect pipe bends, it reduces heat loss and prevents condensation at elbow joints. Suitable for use in plumbing and HVAC installations where thermal insulation of curved sections is required.

## Long description

THERMAFLEX Kolano PE foam 42/9 (DWZ) is a pre-formed elbow section for thermal insulation of pipe bends. Manufactured from closed-cell polyethylene foam, this elbow is shaped to fit curved sections of plumbing and HVAC piping and is intended to reduce heat loss, limit energy waste and prevent condensation at elbow joints. The 42/9 (DWZ) dimensions indicate the nominal pipe diameter and wall thickness designed to match standard insulated pipes and fittings.
Advantages
The PE foam construction provides low thermal conductivity, moisture resistance and long-term dimensional stability. The pre-formed elbow shape allows for quick installation without the need for cutting or complex shaping, ensuring consistent coverage at bends. Its closed-cell structure resists water absorption and helps prevent mold and corrosion on the pipe surface. Lightweight and flexible material reduces mechanical stress on connectors and supports.
Suitable for
 Thermal insulation of curved sections in heating and hot water systems
 Insulation of cold water and refrigeration lines to prevent condensation
 HVAC ductwork pipe runs where elbows require continuous insulation
 Plumbing installations in residential and commercial buildings
Key specifications
 Material: closed-cell polyethylene (PE) foam
 Shape: pre-formed elbow for pipe bends
 Nominal pipe compatibility: 42 mm
 Wall thickness: 9 mm
 Thermal performance: low thermal conductivity suitable for standard insulation needs
 Moisture behavior: water-resistant, reduced water absorption
 Flexibility: designed to conform to curved pipe geometry
How to use
Select the elbow section that matches the pipe diameter. Clean and dry the pipe surface before fitting. Open the pre-formed elbow and place it around the pipe bend so the internal cavity fully encompasses the pipe. Align seams and ensure there are no gaps at the joint with adjacent straight insulation sections. Secure using suitable adhesive tape, clamps or approved adhesive recommended for polyethylene foam insulation. For best thermal continuity, seal seams and joints to minimize air gaps.
Usage recommendations
Install at ambient temperatures within the manufacturer's recommended range and avoid prolonged exposure to direct sunlight or open flame. When insulating pipes carrying cold fluids, ensure seams are sealed to prevent condensation dripping. For outdoor or exposed installations, use an appropriate protective jacket or coating compatible with PE foam to increase UV and mechanical resistance. Follow local building codes and installation guidelines for thermal insulation.
