Precautions
Hot Pipe
- May be installed while the system is in operation, at all temperatures up to 1000°F (538°C).
- Knauf recommends, for insulation thicknesses greater than 6" (152 mm), the temperature must be increased from 500°F (260°C) to maximum temperature at a rate not exceeding 100°F (56°C) per hour.
- During initial heat-up to operating temperatures above 350°F (177°C), a slight odor and some smoke may be given off as a portion of the bonding material used in the insulation begins to undergo a controlled decomposition.
- If natural convection is not adequate in confined areas, forced ventilation should be provided in order to protect against any harmful fumes and vapors that might be generated.
- Care must also be taken when using sealants, solvents, or flammable adhesives during installation.
-
A maximum of 6" (152 mm) wall thickness is recommended.
Cold Pipe
-
Redi-Klad jacket acts as a continuous vapor barrier on piping operating below ambient temperatures.
-
Seal all joints, surfaces, seams and fittings to prevent condensation.
-
Exposed ends of insulation shall be sealed with vapor barrier mastic installed per the mastic
manufacturer's instructions. Vapor seals at the butt joint shall be applied at every fourth pipe section
joint and at each fitting to isolate any water incursion.
-
On chilled water systems operating in high humidity conditions, it is recommended that the same guidelines
be followed as listed above for below freezing applications.
- Exterior hanger supports are recommended.
Redi-Klad
-
Keep adhesive and contact surfaces free from dirt and water, and seal immediately once adhesive is exposed. Redi-Klad Pipe Insulation should be installed in dry conditions with no moisture present.
-
Apply when ambient and insulation surface temperatures are between 0°F and 130°F (-18°C and 54°C).
-
If stored below 0°F or above 130°F, allow insulation cartons to stand within recommended temperature range for 24 hours prior to application.
-
Do not store product below -20°F (-29°C) or above 150°F (66°C).
-
When using Knauf's Redi-Klad closure system, make sure the longitudinal and circumferential joints are properly sealed by rubbing the closure firmly with a squeegee.
-
When using Knauf Redi-Klad Pipe Insulation, the surface temperature of the insulation should be between -20°F and 150°F (-29°C and 66°C) during the life of the insulation.
Fittings and Hangers
- Use metal or PVC fitting covers. For below ambient piping systems, caution should be taken to prevent punctures, tears, or rips in Redi-Klad vapor barrier.
- Additionally, all fitting insulation surfaces must have independent, field applied vapor barriers. Prior to installing fitting insulation, all exposed ends of pipe insulation sections must be vapor sealed.
- Fittings should be insulated to same thickness as the adjoining insulation.
- Apply fittings per manufacturer's instructions.
- When required by specification, a hard insert of sufficient length should be used to avoid compression of the insulation.
Additional Precautions
- Fiber glass may cause temporary skin irritation. Wear long-sleeved, loose-fitting clothing, head covering, gloves and eye protection when handling and applying material.
- Wash with soap and warm water after handling.
- Wash work clothes separately and rinse washer.
- Use a disposable mask/respirator designed for nuisance-type dusts where sensitivity to dust and airborne particles may cause irritation to the nose or throat.
Application Guidelines
Storage
- Protect insulation from water damage or other abuse, welding sparks and open flame.
- Cartons are not designed for outside storage.
Preparation
- Apply only on clean, dry surfaces.
- Pipe or vessel should be tested and released before insulation is applied.
General Guidelines
- All sections should be firmly butted.
- Seal circumferential joint with a minimum 4" (102 mm) wide butt-strip.
- All piping should have continuous insulation.
- Position longitudinal lap at top to minimize dirt and moisture accumulation.
- Do not expose pipe insulation to excessive vibration or physical abuse.
- Insulation thickness must be adequate to assure 300°F (149°C) exterior surface temperature maximum.
