Many people think all doors and windows look the same but here is the checklist to make sure you buy high quality products:
- Aluminium thickness. The thickness of aluminium determines the sturdiness of your product and its price. Often, some suppliers will reduce the thickness to get better margin but at the expense of quality.
- Designs of the profiles. SONNE thermal-break technology allows the profiles to be heat-proof and sound-proof, and provides stronger design. Read more here
- Wheels. Some doors will be very noisy because they use plastic wheel with lesser quality. SONNE products pass quality control test to make sure noise and closing is smooth.
- Handle. The handle influences aesthetics and durability. It is better to choose the heavy-duty accessories if the weight of your door is very significant. Double check the how the handle and lock systems works.
- Glasses. Majority of areas coverage is glass hence having safe glasses with superior heat and sound insulation capability is as important as having thermal-break aluminium. SONNE is ahead of the market by using CCC safety certificated glass and designing double glass that will reduce the sound 2-3 times more effective than single glass. This is because the gap between the two glasses is large and filled with argon gas that allows the sound to be trapped.
- Hinges and locks. It is very important to check the number of hinges and locks used and how they perform together smoothly. SONNE uses top Germany and Asian brands some of which are 100 years old or more that guarantee quality. It also has 6-points lock in its premium window design that is much superior vs 2 standard lock in the market.
- Color-coating. In good quality aluminium, the product does not turn to yellow due to sun and rain. It is important to make sure your supplier can guarantee of this.
- Small details matter. SONNE offers hidden water drainage that make sure the aesthetics of products are good. SONNE designs corner protector for inward- swinging windows.
It is even better if you could visit the product showroom to check all these factors. Please visit SONNE showroom here:
