Seven good tips on how not to fall for windows

How to choose a quality supplier of wooden windows and "not fall for it"!

We have been manufacturing wooden windows for 20 years and based on our experience, we have prepared a "seven good tips" on what to ask a wooden window supplier to make sure you are buying the right one.

1. Are you wondering what the lifetime of your timber windows will be?

Ask how many layers the window finish has and how it is done...

The finish should be a four-layer system for longevity and good looks, plus special protection for corner construction joints to prevent moisture ingress. So at least 4 layers in total!

2. Are you wondering if the windows will really look nice?

Ask if the windows are not only machine-sanded, but also hand-sanded and how many times...

If you want your windows to look nice and not have a rough and ugly surface, your windows should be sanded at least once before each coat of paint. Again, sanded a total of at least 4 times!

3. Are you interested in a nice clean view from your windows ?

Ask how the silicone is applied...

The best way is CNC machine silicone application using a silicone machine to ensure that the glass is nicely and cleanly siliconized.
Improperly applied silicone just comes off the glass badly and makes the windows look very unsightly.

4. Are you interested in low heating costs?

Ask about the heat transfer through the window - U-value, low U-value = low heating costs

If you want your windows to insulate well, ask to see the product performance certificate, where you will find the heat transfer
through the whole product and not just the glass, it is expressed by the heat transfer coefficient_Uw - the lower the better, of course.

5. You want good service = restful sleep

Ask for service

A company that manufactures windows should not only be able to make them well, but also have good service. Ask if the company has a service department and how many service technicians it has. Check the company's organisation board to see if there is a service department.

6. Are you interested in transport and installation - it is not only about making the windows well, but also about getting them to the building site and installing them well

Ask how the supplier transports the windows...

Ideally the contractor has their own transport and their own window stands, but ironically it often happens that the window contractor doesn't put the windows on special transport stands, but nails or screws them onto wooden pallets, which can damage the finish of the windows and often crack the frames.

Ask who does the installation and how...

Installation should be carried out by trained operatives and each product should be treated with the same care as wooden furniture at home.

7. Are you interested in manufacturing ? Take a look directly at the production and see that everything you have been told is true and the company actually produces windows!

If the supplier does not allow you to see the production for any reason, it is always suspicious.
