Deceuninck

Belgian profile group with an Australian head office in Coolaroo, Victoria. Its Australian site describes three systems and lists 23 dealers, but publishes no performance figures, so WERS is the main source for its thermal data.

Deceuninck's Australian site gives no U-values. See the WERS range above for certified Australian figures. Acoustic figures are the company's "up to" values, not whole-window Rw test results.

Certified energy ratings (WERS)

743 uPVC product ratings on WERS, with whole-window U-values from 0.9 to 2.6 W/m²K.

Check the exact product. These ranges cover every glass option. Ask your fabricator for the WERS certificate for the frame, opening type and glass in your quote, and check it matches the U-value and SHGC on your NatHERS or BASIX certificate.

Bushfire

Not stated

No BAL information on the Australian site. Some Deceuninck dealers make their own BAL-40 claims. source

Under AS 3959, uPVC at BAL-40 needs a system tested to AS 1530.8.1, or a bushfire shutter complying with Clause 3.7 over the whole window. For a tested system, ask for the test report covering your profile, glass and window size. How BAL works →
