In windowstock YEAH We manufacture custom-made products, but you should be aware that manufacturing times are usually between 30-45 days and prices increase for custom-made products (short runs), so it is much more advisable, if possible, to adjust the window opening to a standard size.

If you still want a custom-made product, you can request them from the 'Custom' option in the main menu.

Creating custom windows involves extra work in readjusting the machinery, which results in a significant reduction in the number of windows manufactured per day, and therefore increases the cost of the windows and increases delivery times.

At Ventanastock, we strive to provide fast delivery of your windows (24/48 hours) at an unbeatable price. To achieve this, we rely on mass production processes and maintain a continuous stock of all our products. This wouldn't be possible without limiting the size of our products, with standard-sized windows being our primary product.

We are currently expanding our standard catalog so that our models fully meet all your needs. We typically create windows in 10, 15, or 20 cm increments, allowing us to adjust openings to our window dimensions with minimal masonry work.

You must find the window that best fits your opening and modify the opening (widen or narrow) so that it fits the size of the window.

Keep in mind that buying a custom-made window increases the price, potentially doubling the cost of a standard window, so it's better and cheaper to adjust the size of the opening rather than adjusting the window to the opening.

You must measure the height and width of the hole to choose the window size. The measurements of the products in our catalogs always indicate first the total width of the window and then the total measurement of the height of the window, including the blind box if it has one.

After choosing the size, you must select from the different window opening types:

We have opening windows slide (horizontal displacement) with two leaves in which when opening the window one leaf is overlapped over another and the opening area is reduced to 50%. We also have opening windows practicable of one or two leaves in which the leaves move towards the interior of the house and once opened they remain on the sides of the window frame leaving a free 100% of the glazed area. The Windows tilt and turn They are similar to the practicable ones but allow the swing opening of a leaf in which the upper part of the window slopes towards the interior of the house, leaving a small ventilation opening. And finally we have opening windows swingarm in which the window is held by an axis in the middle part of the frame and the sash tilts away from the frame at the top and bottom, very commonly used for ventilation in bathrooms.

- The windows sliders They are the most affordable and allow for opening in small spaces. They are suitable for warm climates and narrow spaces such as galleries or balconies.

- The windows swingarm These windows allow a small opening at the top. They are usually not very large and are relatively inexpensive. The opening is typically around 30 degrees but is adjustable. They allow for ventilation while also providing security by preventing full opening and obstruction. They are perfect for bathrooms and balconies. These types of windows usually have frosted glass, allowing light to pass through but obstructing the view.

- The windows practicable They also have a low price and provide perfect insulation, making them ideal for cold areas.

- The windows tilt and turn They are similar to the practicable ones but also allow the tilting type opening for the ventilation of the rooms, therefore they have the advantages of the two types of opening.

Larger windows and doors are shipped in separate packages. On the one hand the leaves with the crystals and on the other the frame that comes disassembled. This reduces the price of transportation considerably. The assembly of the frame is very simple and is done with just a few screws in less than 5 minutes, but it may take two people during the assembly process. Once the frame is assembled, you just have to insert the two leaves in the guides by means of a simple movement and first inserting the leaf in the upper frame and then in the lower one. the merchandise comes with a simple instruction manual and with everything necessary for its assembly.
