Care & maintenance
Regular and commonsense care and maintenance will extend the life and looks of Altherm windows and doors
Altherm products meet all statutory warranty requirements and are fully tested to ensure compliance with the New Zealand Building Code. There are some simple things you can do to help retain their appeal for many years to come.
Regular maintenance of hardware is recommended.
Powder coated hardware should be cleaned regularly with a wet sponge or soft brush, warm water and a mild detergent and rinsed with fresh water. Plated product should be cleaned with a wet sponge without the use of detergent, as the latter can damage plating.
Stainless steel hardware needs to be cleaned regularly and care needs to be taken when rust spots occur. Even the highest grades of stainless steel can develop rust spots and these can be removed with a mildly abrasive cleaner and rinsed with fresh water. In cases of heavy corrosion a Scotch-Brite™ hand pad can be used. Specialised 3M® Stainless Steel Cleaner and Polish is also available as an alternative cleaning compound.
Glass is a very delicate product that can be easily damaged.
Care is needed to ensure that scratching does not occur. Only detergents and cleaning solutions which are recommended for glass should be used. Begin cleaning by soaking the glass to loosen dirt. Then using a mild, non-abrasive solution, uniformly apply to the glass surfaces. Ensure that the solution is removed by rinsing with water as cleaning residue can permanently mark glass.
To comply with warranty requirements and to ensure longevity of Smartwood windows and doors, the interior timber face should be sealed as soon as possible after installation with an appropriate finish , for example, oiled, varnished, stained or painted, according to manufacturer’s instructions.
If the timber is oiled or stained, this treatment will need to be reapplied every few years to maintain the appropriate level of product protection and appearance.
