Door and window joinery is one of the most expensive components of finishing the building. The choice of the windows is best well to examine before making a decision. Although the technology used by us has a huge impact on the properties of the windows, for you it should not mean much. To make the right choice it is important to get a certificate for whole window stating his actual performance and ensure that You pay for a product You really need.
When buying a window, we often engage in discussion about the details of their design, the advantages of their components and perfect attention to detail. In this way, we get caught in marketing trap - we do not choose the product on which we depend, but praised by the reseller. Meanwhile, a good choice is to buy such a window that fully meets our individual needs and is appropriate certificates. Warm window, not only worm glazing. Safe, but not one that has a few anti - burglar caches. The windows, which in practice will be tight and easy to use, and not one that theoretically has a chance to be such, because it says the vendor. Without specialized survey product is not complete. The window consists of many small and large components and it goes a long road from the factory to be fixed in the wall. Its test certificates gives investors a guarantee of buying a product with the declared parameters. Then the technology does not matter, what matters is only the end result, that is why our products are equipped with all the necessary certificates and declarations of properties, so you know that you bought this exact product that you wanted.
What you get:
Energy-efficiency certificate: Declaration of properties: Technical approval:
By specified in the regulations and standards properties that must meet the joinery we can prepare for you a set of parameters that correspond to the data window, allowing you to choose the most suitable offer in not only price but also in terms of technical characteristics. It is important to include the most matter information for us. First, you need to specify the size of the window, choose its partition and functions of the hardware, for example the double window with a fixed bar with dimensions of 147 x 147 cm. These basics are usually defined in the project and do not make trouble. The more difficult is the further part when You to specify expectations for the characteristics of windows
