Insulation

Insulation

UBEMS always uses materials which are comply with the fire and smoke hazard ratings indicated by ASTM-E84, NFPA 255 and UL 723. Accessories such as adhesives, mastics, cements and tapes shall have the same or better fire and smoke hazard ratings.
Special care take in application of insulation e.g Insulation application on all cold surface mechanical systems, such as ductwork and piping, where condensation has the potential of forming and in accordance with Standard.

Duct Insulation

Materials used as internal insulation exposed to the air stream in ducts shall be in accordance with UL 181 or ASTM C 1071 erosion tests, and shall not promote or support the growth of fungi or bacteria, in accordance with UL 181 and ASTM G21 and G22. Ductwork with double wall construction having insulation in-between shall only be used for courtroom return air transfer grilles, and only if required for acoustic purposes. All exposed ductwork shall have sealed canvas jacketing. All concealed ductwork shall have foil face jacketing.

All the insulations are comply with fire and smoke hazard ratings indicated by ASTM-E84, NFPA 255 and UL 723. Accessories such as adhesives, mastics, cements, tapes, etc. shall have the same or better component ratings. All supply air ducts always insulated, in accordance with Standard 90.1.

Protect Supply air duct insulation with vapour barrier jacket. The insulation cover the duct system with a continuous, unbroken vapour seal. Insulation shall have zero permeability.

Return air and exhaust air distribution systems always insulated in accordance with the Standard set standards.
Always evaluate insulation of return air and exhaust air distribution systems or each project and for each system to guard against condensation formation and heat gain/loss on a recirculating or heat recovery system. Generally, return air and exhaust air distribution systems do not require insulation if located in a ceiling plenum or mechanical room used as a return air plenum.

Piping Insulation

All of our insulation materials are comply with the fire and smoke hazard ratings indicated by ASTM-E84, NFPA 255 and UL 723. Accessories such as adhesives, mastics, cements, tapes, etc. shall have the same or better component ratings. Piping systems conveying fluids, those having design temperatures less than 18°C (65°F) or greater than 40°C (105°F) shall be insulated. All piping systems with surface temperatures below the average dew point temperature of the indoor ambient air and where condensate drip will cause damage or create a hazard shall be insulated with a vapor barrier to prevent condensation formation regardless to whether piping is concealed or exposed. Chilled water piping systems shall be insulated with no permeable insulation (of perm rating 0.00) such as cellular glass. All exposed and concealed piping shall have PVC jacketing.

 All insulation material shall comply with the fire and smoke hazard ratings indicated by ASTM-E84, NFPA 255 and UL 723. Accessories such as adhesives, mastics, cements, tapes, etc. shall have the same or better component ratings. All equipment including air handling units, chilled and hot water pumps, and heat exchangers must be insulated in accordance with Standard 90.1. All pumps shall have jacketing.

Thermal Pipe Insulation for Plumbing Systems

All sanitary sewer vents terminating through the roof shall be insulated for a minimum of 1.83 meters (6 feet) below the roof line to prevent condensation from forming and include a vapor barrier jacket on this insulation. All Insulation materials and accessories shall comply with the fire and smoke hazard ratings indicated by ASTM-84, NFPA 255 and UL 723.

All piping exposed in plenums or above ceiling shall be insulated to prevent condensation. All insulation materials and accessories shall comply with the fire and smoke hazard ratings indicated by ASTM-E84, NFPA 255 and UL 723.
