Our UPVC doors are manufactured from slim thermally broken profiles to ensure maximum glass widths can be achieved using the minimum number of panels. Glass specification is key when affecting the doors’ thermal performance as glass generally accounts for 80% of the surface area of the doors. Our doors include multiple rigid rubber seals and draught excluders to ensure that you get nothing but sunlight passing through your doors. Our door system utilises the latest polyamide thermal barrier technology. This advanced profile technology creates a thermal transmittance barrier between the cold outside and the warm inside. This retains heat, reduces condensation and insulates your property from external noise and weather conditions.

How to measure

Below we have a guide on how to measure your opening to ensure you choose the correct size for your chosen product.

How To Measure A Door Opening

If you don’t have an existing door or frame in place, things are a little bit more complicated. Start by measuring the height of the brickwork opening in 3 places, on the left-hand side, in the centre and the right-hand side. Do the same for the width, measuring at the top, middle and bottom. Note down each set of measurements and take the average of each set to determine the size of the door opening.

If you’re ordering a door frame, you’ll need to allow a fitting clearance to make sure the frame fits into the door opening without forcing. If the frame gets forced at any point during the fitting process it can be knocked out of alignment which makes door fitting and operation difficult. The usual clearance to allow is 10mm. Deduct this from your previous calculations to find out what size you should opt for when ordering a door complete with a frame.

Measuring an Open Frame

Measuring an open frame is similar to measuring the door itself.  Complete the same process as above but measure the gap where the door would be. Be sure to take into account the thickness of the carpet you plan to lay when measuring the height of the opening. When measuring the width of the door, take three measurements (top, middle, and bottom) and use the narrowest as the opening width.

The measurement you take for the thickness of the door will depend on whether you are buying an interior or exterior door. If you are buying an exterior door, then the thickness of the door should be the measurement from the sheetrock to the exterior sheeting. For an interior door, take the measurement from sheetrock to sheetrock.

Other Things to Consider

Finally, pay attention to the way the door opens. Stand so that the door opens towards you, and note whether the hinges are on the right or left-hand side of the door. If the hinges are on the left-hand side, then you should purchase a left-hinged door. If they are on the right, then you need a right-hinged door.

Take your time when measuring the door or frame, and be sure to double check all of your measurements. The old adage “Measure twice, cut once” exists for a reason! Taking a moment or two to make sure that you order the right size door will save you a lot of stress in the long run.
