Measuring Guide How to measure for Clearview Secondary Glazing
Step 1 Familiarise yourself with the product The image below depicts an out of square window reveal, common in older properties. For secondary glazing, measure the primary window reveal in several places vertically and horizontally to find the narrowest width and height measurement. Then deduct 10mm. That s tolerance deduction, the measurement we need to make your secondary glazing unit. It is better to have the secondary glazing unit slightly too small, if too large it may be unusable. Gaps allow for leveling adjustments and are covered by the supplied trim*. The secondary unit is square, with parallel sides and 90o corners. Install as level as possible to ensure optimum insulation levels. Once fitted, attach supplied trims, scribing to cover any gaps around the unit or walls, and cover fixing screw heads. Fix edging trims with a silicon/ caulk sealant or no nails type adhesive. *Supplied trim is 27mm wide. Narrower or wider trims can be purchased as an optional extra.
Step 2 What is Face and Reveal? Before you start to measure your primary window, check you know where the face and reveal are. Two important things to remember: 1 Measure in millimetres and 2 Measure the primary window from inside. White area is window face White area is window reveal
Step 3 Take width measurements Take several measurements, always in millimetres, across the primary window width, top, centre and sill, taking the tape measure right into the corners.
Step 4 Take height measurements Take several measurements, always in millimetres, across the primary window height, left, centre and right, taking the tape measure right into the corners.
Step 5 How to measure window panels For Horizontal sliders - Start from the left. Measure from the wall to the centre of the first mullion/pillar. Then, measure from centre point to centre point on the remaining mullions/ pillars. These measurements confirm any unequal panel sizes. For Vertical sliders - Always measure from the top down to the centre of the mid rail. This confirms if the panels are equally split. Measure to centre mid rail Measure to centre of panel frame
Step 6 Making tolerance deductions From your narrowest width and height measurements, as explained on page 3 and 4, we recommend a 10mm deduction from the width (A), the height (B) and a 5mm deduction from the first panel (C). Remaining panels require no tolerance deduction. See page 1 for an explanation of tolerance deduction. Example: how to calculate correct size, based on the window style shown below. A 1847mm-deduct 10mm=1837mm B 1606mm-deduct 10mm=1596mm C 620mm-deduct 5mm=615mm D 610mm no deduction =610mm Measuring example on a 3 pane window for a 3 pane horizontal slider
Step 7 Measuring points for horizontal slider Follow these measuring points and refer to page 6, Making tolerance deductions. Send us only your A, B, C (D etc.) measurements in order to make your secondary glazing unit.

Step 8 Measuring points for vertical sliders, lift out and hinge units Follow these measuring points and refer to page 6, Making tolerance deductions. Send us only your A, B, C measurements in order to make your secondary glazing unit. C B A Vertical slider Lift Out Hinge Unit
Step 9 Measuring splayed reveals A splayed reveal is a window set in an angled recess, as shown here. This means the window unit is wider at the front. The front width dimensions is required for pricing and manufacturing. The next page shows you how to calculate specifying the correct measurements for secondary glazing. Example of a splayed window reveal. Note the angled sill.
Step 10 Make a template Make a simple template with a square of dark paper or card. A. Position the template where the sill joins the window frame. B. Move the template towards the outer corner, carefully folding in a line with the splayed reveal. C. Fold the edge back on itself, making sure you are satisfied with the accuracy of the fold angle. B Fold the template A Position the template C Check the template
Step 11 Find the angle of the template Follow A to E to give the angle of the splayed reveal. Or post your template/s to us: Clearview Secondary Glazing, 51 Clarkegrove, Sheffield S11 8RU. Mark the templates to identify the unit/s involved" A Cut to shape B Trace the angle C Check angle D Measure with a compass E The angle of the splayed reveal
Step 12 Remember... We need the width to the front of the unit for pricing and manufacture. Measuring Your Splayed Reveal If face fixing or you know the width at the back of the unit, to where it will be sat in the reveal, use the following matrix to calculate the front width from the angle details.

Step 13 No reveal? Remember... You will need to advise us if your primary window is surface mounted / flush with the wall, and has little or no sill, remember to measure within the architrave as indicated in the example here. This is where the secondary glazed unit will be positioned. Because the unit will protrude from the wall, you will need to consider the finishing trim. The 28mm standard trim supplied, will require cutting to fit and will not cover the sides. As an optional extra at the time of ordering, you can request a 21mm trim for the front face and a wider trim e.g. 45mm for the sides.
Top tips for a tip-top job. Following this measuring guide will help you to achieve optimum insulation performance from your Clearview secondary glazing, and enhance its discreet appearance.
