Windows, as we know them today, originate from the beginning of the 15th century. A lot has changed in the window industry regarding the technology behind window manufacturing. The industry as a whole has seen significant improvements across the board, especially with energy efficiency as modern double glazed windows have become much better at reducing heat emission from your house.

While our production facility staff is hard at work, we’re also cooperating with several incredible suppliers who likewise are essential for the quality of our made to measure windows and door offerings.
We have decided at Klar Windows that we want to pay extra for the good materials and to decrease our margins to offer you a better deal.
At Klarwindows we have a different company structure than our competitors which grants us the possibility to drive the price down while providing an equal or greater quality finished product.

Our production facility and a large amount of our staff is located in Estonia, a country known for its heritage and traditions within carpentry and woodworking. Estonia is also one of the few countries in Europe where pine trees have the best growth conditions and with plenty of pine trees readily available, the process from cutting down the trees to manufacturing the windows is short and efficient.
Moreover, pine trees need the average temperatures of the climate to be extremely low in order for the core density of the wood to be strong for high-quality timber products. And Estonia is one of those countries where this exact requirement is met.
As you can hear, we’ve taken every aspect into close consideration when developing Klar Windows. The reason is simply to deliver the best made to measure double glazed windows for the best possible price.
With so many competing businesses it can be difficult to figure out what offer is the best offer. To give a quick overview we can segment window manufacturers/suppliers into two categories:
The first one is:
Here you can only apply to “get a quote” through a salesperson. In most scenarios, this results in higher prices on windows, because you’re paying for someone to make your quote. And the actual process of receiving an offer is slow and cumbersome. Typically, you will also pay a hefty amount for measurement and installation.
The second type is:
This is Klar Windows. We are a relatively new competitor in the business, and we aim to change the way buying made to measure windows has typically been done. By offering a wide range of products and a do-it-yourself configurator, you can decide your own deal. By deciding on your own offer, you’re technically cutting out the middleman and thus saving the cost it would’ve required for you to get a professional carpenter/installer to make the measurements of your double glazed windows. Which you can do perfectly fine yourself:
