Cleaning our uPVC doors and windows is super easy. All one needs to do is regularly wipe it with a wet microfiber cloth and that is more than enough to give your door a long service life.
Both anodised and painted aluminium should be cleaned on a regular basis. Warm water should be used with a dilute of a non-aggressive, non-acetous detergent without ammonia for cleaning the aluminium. Then you should thoroughly rinse the aluminium with clear water and dry using an absorbing cloth. If water and mild detergents are not enough to clean the aluminium fenestrations there are detergents that have been specially developed for aluminium surfaces. These detergents contain light abrasive elements and can be used with a synthetic cleaning cloth. In all cases, it is important to completely rinse surfaces with clear water and dry them thoroughly, especially the corners and the bottom profile. In order to protect and increase the life cycle of the aluminium, it may be treated with a very thin clear coat of water-resistant film available.
The aspect ratio of any item is the proportional relationship between its width and its height. It is commonly expressed as two numbers separated by a colon, as in 16:9. In the case of windows, it purely depends on the window sizes which are given by the architects and designers. A Fabricator can always refer to the max & min size limitations given by Salamander in the guidelines. It plays a major role in the structural stability & functioning of the windows. For e.g. in a casement system, the recommended aspect ratio is 1:1.5. Whereas in Sliding Height to Width Ratio should be less than 1:2.5
The heat transfer coefficient (k- or U- value) is the amount of heat in watts per unit of time, which is transferred through 1 sq.m of glass surface per degree Kelvin difference between internal and external temperature. A measure of the rate of non-solar heat loss or gains through a material or assembly. The lower a window’s U-value, the less non-solar heat it transmits.
