We continuously strive to meet our customers' expectations.

Here at the Kolcz Joinery we pride ourselves on using the best woodworking technologies available and meticulous craftsmanship to offer you only the highest standard in quality and longevity of our products.

• We use the best glazing sealantsand finishes (lacquers) available that are easy to reapply should you wish to redecorate your windows.
• For installation of glass in wooden-frame windows we use a special glazing compound which seals out the weather and separates the glass from the wood to enable the materials to independently react to the weather conditions and the temperature outside.
• Double glass window panes separated by a gas filled space are the most frequently used solution in our windows. The units are manufactured with glass of thickness of 24 mm. Glass of different thickness can be used according to the customers' specifications.
• High quality pine and oak are the most common types of wood we use. At times, we tend to mix and match these in order to better adapt the products to the weather conditions. We’re always excited to provide you with consultancy service to talk over the details and possible changes but also show you samples of our products.

When deciding between wooden or PCV windows you should remeber that both materials have similar technical specifications and both make high quality materials. Wood, though, has been the natural material throughout the centuries used in the production of windows, doors, floors, decors and ornaments, and is very durable and resistant to damage. Apart from excellent technical specs, wood has a lasting appeal and naturally brings out the esthetics and beauty of your interiors.

Thanks to modern wood processing technologies used at the Kołcz Joinery, the products we offer meet the highest standards of quality, longevity and durability. Our products meet all current building regulations.

Timber does not emit any harmful or toxic substances, which makes it a perfect solution for those suffering from allergies.

Using timber as a building material minimises the amount of electricity used during the window manufacturing and finishing stages as well as in leftover wood utilisation.

Also, wood is easy to work, shape, craft and contour – a quality which allows us to create unique and exclusive window frames.

Different colours and shades of timber alongside its various structures make it a unique natura material to work with. Thanks to these qualities timber brings out the beauty and esthetics of every interior, which no other wood verneer is capable of.

Wooden frames can be painted, lacquered or varnished in any chosen colour. Should you wish to change the colour of your wood finish, all that needs to be done is to redecorate it with a chosen finish. This simple step would be impossible to do on PVC windows which must be replaced at high cost to acheive the same result.

Wooden frames bring you the highest performance in heat insulation and very low energy loss.

Glazing you windows with better quality glass and other security features such as special harware fittings, can burglar proof them. Also, using window shading will protect your windows from the sun.

Unlike PVC windows, wooden frames are resistant to changing temperatures. Timber used in our products is base coated with wood preserver to prevent any rot, weather and insect damage.
