Ua tsaug rau nws cov khoom zoo heev thiab cov kev pabcuam zoo, UNT Duct yog ib qho ntawm cov ua pir pre- insulated hvac duct board manufacturers thiab lwm tus neeg nyob hauv Suav teb. Txais tos mus yuav cov khoom zoo thiab customized los ntawm peb lub hoobkas. Peb yuav muab kev pabcuam zoo tshaj plaws thiab xa khoom sai rau koj.

 

Raws li Australia tseem tab tom ntsib cov nqi hluav taws xob nce ntxiv, cov cai nruj me ntsis hauv tsev (NCC 2022), thiab kev tsom mus rau kev ruaj khov, HVAC cov kws tshaj lij thiab cov neeg tsim khoom xav tau ntau dua, ruaj khov, thiab ua raws cov kev daws teeb meem.PIR (Polyisocyanurate) Ua ntej- insulated HVAC Duct Boardyog tawm los ua ib qho kev xaiv zoo tshaj rau cov tsoos galvanized hlau (GI) ducting nrog cov rwb thaiv tsev sab nraud.

 

PIR Pre-insulated Duct Board yog dab tsi?

PIR duct board yog ib qho nyuaj, lub teeb yuag vaj huam sib luag muaj xws li:

Core:Siab- qhov ceev kaw- xov tooj ntawm tes PIR ua npuas ncauj - inherently hluav taws kub- tiv taus thiab muab kev ua haujlwm thermal tshwj xeeb.

Facings:Ob sab yog sib txuas nrog cov ntawv txhuas (feem ntau yog 60 lossis 80 microns tuab), muab lub vapor barrier, lub zog muaj zog, thiab qhov chaw huv huv.

Tsis zoo li tsoos ductwork (hlau + fiberglass / roj hmab rwb thaiv tsev), lub rwb thaiv tsev yogib qhorau lub vaj huam sib luag, kom ntseeg tau tias kev ua haujlwm zoo ib yam tsis muaj qhov khoob lossis compression.

1. Superior Thermal Efficiency (High R-Value)

Australia cov huab cua txawv txawv - txij li QLD lub caij ntuj sov mus rau lub caij ntuj no VIC/ACT txias - xav tau siab - rwb thaiv tsev ua haujlwm.

R-Tus nqi:PIR muab kwv yees liR1 rau 20mm thickness. Qhov no ua tau zoo dua fiberglass lossis EPS ntawm tib lub thickness.

Qhov tshwm sim:Txo qhov kub nce / poob, txo HVAC lub sijhawm ua haujlwm, thiab txo nqi hluav taws xob - qhov tseem ceeb rau NABERS thiab Green Star kev ntaus nqi.

2. Ua raws li Australian Standards

AS 4254 (Ductwork rau huab cua-khiav tshuab hauv tsev):PIR duct board systems tau ua raws li tag nrho thaum ntsia nrog kev pom zoo sib koom ua ke.

AS 1530.1 & AS/NZS 3837 (Cov khoom hluav taws kub):PIR muaj cov nplaim hluav taws tsawg tsawg, kev tsim cov pa luam yeeb tsawg, thiab tuaj yeem ua tiav Pawg 1 lossis 2 qhov ntsuas hluav taws kub. Tsis zoo li tus qauv polystyrene, PIR chars tsis muaj dej ntws tawm.

AS 4859.1 (Cov khoom siv thermal rwb thaiv tsev):Ua tau raws li qhov yuav tsum tau ua rau R-tus nqi thiab kav ntev.

3. Kev ua tau zoo hluav taws kub rau kev nyab xeeb hauv tsev

Ua raws li kev hloov kho lub tsev loj tshaj plaws -Grenfell thiab Australian cladding txwv, kev nyab xeeb hluav taws yog qhov tseem ceeb.

PIR muaj ib qhopib - qhov kub thiab txias> 400 degree.

Raws li nplaim taws-resistant (tsis muaj ntxiv halogens).

4. Sab hauv Cua Zoo & Pwm Tiv Thaiv

Lub kaw - cov tub ntxhais ntawm tes tsis nqus dej noo. Lub ntsej muag aluminium tsim ua tiav vapor barrier, tiv thaiv condensation thiab pwm kev loj hlob hauv cov kav dej.

Smooth tha xim sab hauv phab ntsa tiv thaiv cov plua plav tsub zuj zuj thiab yooj yim los ntxuav, txhawb nqa IAQ zoo - tshwj xeeb tshaj yog tseem ceeb rau kev kho mob thiab chaw ua zaub mov.

5. Lub teeb yuag & nrawm dua

PIR board weighs approx. 1.4–2.5 kg/m² (for 25mm board), compared to 4–8 kg/m² for metal + external insulation.

No heavy lifting, no external insulation wrapping, no welding required.

Cuts and fabricates with simple hand tools or grooving machines.

Txo cov txheej txheem kev txhawb nqa thiab lub sijhawm teeb tsa txog li 50%.

6. Zoo heev Acoustics

PIR core absorbs kev co thiab txo cov suab nrov hauv huab cua (kiv cua nrov) thiab cov qauv- ua suab nrov (rumbling).

Hom suab attenuation:>25dB ib meter, tshem tawm qhov xav tau rau sab nraud acoustic lagging hauv ntau daim ntawv thov.
