Cleaning and maintenance

1How can I clean my aluminium windows and doors?
Cleaning should be done with a soft sponge or cloth with a solution of water and neutral detergent at a 5% concentration.
2How frequently should I clean my windows?
The cleaning should be done at 6 months intervals, 3 months intervals if in an industrial area. Near the sea we advise cleaning every month. Sliding windows and doors tracks should be cleaned regularly to ensure the correct functioning of the rollers.
3Which detergents can I use when cleaning aluminium windows and doors?
Neutral detergents (pH from 5 to 8) diluted in water at a 5% concentration (50 ml of detergent to 950 ml of water). Do not use abrasive detergents, acid or alkaline products.
4What maintenance do aluminium windows and doors need?
The functioning of the hardware should be checked and if necessary lubricate with fine oil, removing the excess with a dry cloth.
5What cares should I have to protect the frames when painting a room?
The frames should be protected with PVC adhesive tape, avoid paper adhesive tapes. Remove the tape after finalizing to avoid damage that long exposure to the glue might cause. If paint gets to the aluminium it should be cleaned immediately with a dry cloth and right after with a damp cloth (with water and neutral detergent).

General Questions

1What is a double glazed glass?
A double glazed glass is an insulated glass unit that combines two panes of glass separates by a spacer.
2What is low-e glass?
Low-e glass refers to low emissivity; it is standard clear glass that has a special coating on a surface of the glass which is capable of reducing the amount of heat that is conducted through the glass.
3What’s the difference between laminated and toughened glass?
Both are classified as safety glasses. Laminated glass is composed of two or more panes of glass glued together by an interlayer of polyvinyl butyral (PVB). When the glass shatters it remains stuck to the interlayer. Toughened glass is a single pane of glass that was treated chemically or in a heat furnace which makes it stronger and able to withstand larger thermal amplitude. If broken it shatters completely in small blunt pieces making it less likely to cause injury.
4What is the thermal break?
Thermal break or thermal barrier is the union of two aluminium profiles with polyamide ramrod(s) that prevent heat transfer from the inside to the outside and vice-versa. It also allows the use of two distinct colors, one on the inside and other on the outside.
5What is the U-value?
The u-value, heat transfer coefficient (U= W/m2.K), is the energy in watts that is transferred in an area (expressed in square meters) when there is a 1 degree Kelvin difference from inside to outside.
6How much does glass weight?
Glass weights 2,5kg/mm/m2, for example, a 5mm thick glass pane weights 12,5kg per m2.
