For zinc-aluminium alloy coated steel, avoid copper, lead, green or treated timber, stainless steel and mortar or concrete.

The unique IMETAL roofing compresses blanket during installation making fixing easy. Blanket up to 50mm in thickness can be readily used and is known to provide at least STC25. For better and specific acoustic requirement, kindly contact our personnel.
For tropical weather, IMETAL recommended double sided AI foils or bubble foils with of min 9 micron. A buildup of metal roof with AI foils, coupled with sufficient air gaps is proven to bring down the heat to comfortable level. For better and specific thermal requirement, kindly contact our personnel.
IMETAL decking can be easily cut, where required, using a power saw with a steel cutting blade or a power nibbler and, for localized cutting, tin snips. Avoid the use of abrasive discs as there can cause burred edges and coating damage. Cutting using abrasive disc also results in unsightly edges. As good practice, clean the roof everyday after finishing work for the day.
As with all roofing products, we recommend extra caution be taken when walking on the roof. When walking on IMETAL roofing always wear flat rubber soled shoes and place feet only in the pans, taking care to avoid the last pan or two near edges of the metal roof area.
