So, you’ve decided it’s time to get new replacement windows because you’re interested in lowering your energy bills. You’re not going to be happy about it, and we are not in the business of making unhappy customers. I could cut through it, but it would take too long and the risk of jolting the device would be too high. When fitted brick to brick the outside facing side of a sash box is usually ‘dressed’ which some trim (as shown in the picture to the right or above on a mobile device). The picture to the left (above on a mobile device) shows a 165mm thick sash box which is too deep for the 140mm reveal. Measuring from the outside to the inside (see picture above). Step 2: Measure the width of the outside opening in three places; at the bottom, middle and top of the opening, the measurements should be the same but if they are notably different then check to see if there is a visible reason why; this could be because one or more bricks are uneven and the majority of the opening is the same width.
If your measurements differ significantly check to see if there is visible uneven bricks or slight subsidence. Check all of your measurements at least once again to make sure you’ve made no mistake.

If they have any rot or water damage you will need to order new construction windows. Have you decided it’s time to replace those old, drafty windows? You don’t have to be familiar with what windows you currently have and how they differ from the windows you want to replace them with. You don’t have to know that accounting for the insulation in the trim of your new windows is vital in getting an accurate measurement. Remove the old sliding windows from inside the frame. You should keep in mind that when you involve the old frame, you will end up having a smaller window than the space available. First, you need to determine if you want to install a new window inside the existing frame, or do you wish to completely remove the old window, so that you can fit new window frame along with the screens.
Measuring a sliding sash window correctly is actually quite straightforward, but please remember the old builder’s maxim ‘measure twice, cut once’. Step 1: Measure the depth of the existing sash box. If your existing wood window has range jamb liners, remove those to measure the inside height of the frame. Before ordering replacement windows, make sure the wood frame surrounding your windows are in good condition. Here, our window experts explain how to measure for replacement windows. Use a tape measure will clearly determine if the bottom, mid and upper points of the width of the window are the same. Using your tape measure horizontally, measure the inside of the jamb, left to right. Using your tape measure vertically, measure from the highest point of the sill to the top of the window opening. For better access to the jamb, open the window sash and measure. Using a rebated sash reveal allows the sash box to sit in a recess hiding both the front facing sides and top of the sash box so that only a small part of the window frame is visible or ‘facing’ on the outside. Step 5: The frame width of our sash window profile 145 and 150 is also 100mm at the and sides, and like the top, the sides of a sash box should also ‘face’ (show) 20mm at either side with the remainder of the box hidden behind the reveal.
Some original recesses were built quite tight at the top, or the lintel may have ‘bowed’ over time, so adding 80mm could mean the sash box will not fit in the recess at the top. Using a deeper frame means architrave will have to be packed out which can look very bulky and not in-keeping with period properties. In a home window replacement project, you have the opportunity to change the operation style of your existing window or even put in a patio door. Replacement windows are a great investment in the value of your home or business. Profile 190: This sash box is 190mm deep, is only for use on sash windows with triple glazing is only suitable for new builds. Profile 165: This sash box is 165mm deep, is most suited to new builds but can also be used in period properties with deep reveals or with the use of reveal liners.
Profile 150: This sash box is 150mm deep, is suited to both period properties and new builds. Take the measured outside opening height taken in step 3 and add 80mm, this is the exact height of your new sash box/window. Step 3: Now take the smallest measurement of the three widths and heights and take off 10mm. This is the correct size you need to order. Repeat this process for every window in the house, even if some windows appear to be the same size. The first step in measuring for a window replacement is to understand your existing windows and the aperture (opening) they are currently in. Step 4: The frame width of our sash window profile 145 and 150 is 100mm at the and top, typically a sash box should ‘face’ or show 20mm at the top with the remainder of the box hidden behind the reveal. 1. From the outside of the home measure the width of the opening at top, middle, and bottom. You may take three evenly spaced measurements and choose the largest of each, but if you intend to cover the entire window you may simply measure at what seems to be the largest point.
