We have transformed more than 50 years of product knowledge and excellent customer care into the easiest digital experience and will help and guide you seamlessly through everything from design inspiration, technical concerns, and measuring your windows to ordering.

Certified friendly shop

Your order with us is certified to protect you and our planet.

Klar is a fusion between Danish and Estonian craftsmanship and carpenting expertise. We offer a wide range of windows and doors to affordable prices in Scandinavian design heavily inspired by the classical, minimalistic style you so often see in Estonian, Swedish, Danish and Norwegian homes. Our products are first and foremost created with durability in mind. We’ve partnered with Scandinavia’s leading manufacturers with regard to glass, locks and wood to ensure that you get the best possible windows and doors. 

We have a large selection of types of windows and doors for you to choose from. Although Scandinavian windows and doors follow a certain inspiration, the designs typically differ and as such, we have eight types of windows to choose from:

Our Windows:

  1. Top Guided Windows

  2. Fixed Windows

  3. Cottage Windows

  4. Casement Windows

  5. Georgian Windows

  6. Combination Windows

  7. Opening Floor to Ceiling Windows

  8. Fixed Floor to Ceiling Windows

Our Doors:

  1. Front Doors

  2. Patio Doors

  3. French Doors

  4. Doors with Sidelight

  5. Sidelight to Front Doors

All of our windows and doors are made-to-measure

You can customise your windows and doors exactly to your liking with your needed measurements. Choose between materials, colours, handles, glass types and glazing. When choosing your new windows and doors, the most important aspect is figuring out which type of glazing you’d ideally want. At Klar, our minimum is double glazed windows and the same is with our doors. That is simply because double glazing ensures a large amount of energy efficiency. If you’d like, you can opt for triple glazing, resulting in excellent insulation and an even bigger reduction in condensation on the glass. 

One important thing to know about the materials we use, specifically with regard to our timber, is that we only use slow-grown high-quality FSC pine wood without knots. That is simply to ensure maximum durability for our doors and windows.

We also offer our doors with either double glazed or triple glazed windows. Choose between wooden front doors or aluminium composite front doors. If you’re looking for patio doors, we offer these as either wooden patio doors or AluClad patio doors.
