Air ducts are an important part of any climate control system, which is responsible for the supply and removal of air. A well-selected insulation material and its correct installation are thermal insulation, noise insulation, anti-condensation, energy saving and safety of any ventilation system.
There are two ways to isolate the ducts: with self-adhesive rubber sheet insulation or conventional rubber insulation paired with contact glue.
The first thing to do: measure the box to be insulated.
Note: Add 5 mm on each side so that the seams of the installed material are compressed.
Using a cleaner, clean the entire insulated surface. Cut out the rubber insulation sheets according to the dimensions shown in the figure.
- Apply a thin layer of glue to the metal surface of the duct, and then to the rubber sheet.
- After the glue has dried a little ("finger method"), install rubber insulation on the glued surface and gently press it for good adhesion. Continue working by applying glue to both surfaces, including the edges of the sheet material and installing insulation on the duct after the glue dries a little.
Note: Remember that the sheet insulation should be glued in the direction along the duct, not across
Rubber sheets cut to size should be installed with an overlap of 5-10 mm. In places of overlap, do not apply glue either to the rubber sheet or to the surface of the duct. Where the two sheets connect, leave a 30 mm strip and the duct surface without glue. Being compressed, the seams provide the greatest strength and tightness. The material should not be stretched. After installing the sheet, fill the insulation in the place of overlap, in the seam and glue by the method of "wet gluing". If you have chosen the option of installing air ducts with self-adhesive sheet material, then you will not need additional accessories for installation.
Using a cleaner, clean the entire surface from grease, dirt and dust. Cut the rubber sheet to size. Remove the protective film and place the sheet on the duct. Press down hard so that the adhesive layer adheres to the surface. Align the material and continue to install the insulation by pressing it down and slowly removing the protective film. At the butt joints, leave an overlap of 5 mm to compress the material. After installing the sheet, fill the insulation at the overlap point into the seam and glue it using the "wet gluing" method.
High-quality insulation and proper installation of air ducts will extend the service life of the climate system.
