It's A Door Fitting Bow Success Story You'll Never Imagine
How to Avoid Door Fitting Bow Problems

Bow window installation is a large task that should only be undertaken by professionals. It involves extensive framing and construction of a header for a window.


Bow windows should be equipped with weathertight seals and provide effective protection against damage to the interior doors. Inspections should be documented at intervals that are not more than monthly.

Bowing in the Thermal Bowing

The difference in temperature between the outside and inside of a door could cause one side to expand and expand while the other remains in a more stable state. This is known as thermal bowing and can make it difficult to latch hardware or open the door. However, it isn't permanent and it can be corrected in many cases by simply adjusting the latch and strike hardware or applying lubricant to help the metal parts slide more easily.

The type of core used in the door also plays a part in thermal bowing. Polyurethane and polystyrene-insulated doors tend to bow more because they are not able to evenly distribute heat throughout the panel, while a honeycomb-based core allows heat to flow more easily through the panels. The color of the panels can influence its thermal behavior. Colors that are darker absorb heat more effectively, which can increase thermal bowing.

IMP representatives are well aware of the impact of thermal bowing on their products and can offer customers advice on proper installation. Knowing the project location as well as the performance and aesthetic requirements, the structure of the building and the intended use allow the IMP representative to perform calculations that will to eliminate the problem of bowing on doors by ensuring that the panels are built with the proper amount of structural support framing.

As they move between cool and hot climates, homeowners often are aware that their solid wood doors begin to crack. This is due to an extreme variation in humidity and temperature between the inside and the outside of the house. The warping is not a manufacturer defect and can be prevented by keeping air and heating conditioning vents away from the doors. The door hinges can also become stuck when they are opened and shut because of the temperature difference on the opposite side of the door. This could be caused by moisture entering the door through a poorly sealed frame or the weather strip that surrounds the frame. Despite these issues, many solid wood doors can be saved by making minor adjustments.

Clearance Issues

There are many issues in the installation that impact the proper fitting and operation of doors. One of the most important is edge clearances. This refers to the distance between a door and the frame head jambs, head or between the two leaves of the pair. When the door or frame is affixed to the head, jambs, or other doors this is an edge clearance problem and can result in friction which may damage the frames, doors and other hardware. This can be caused by an incorrectly anchored frame in the wall or a miscalculation of the height of the head as well as the jambs, resulting in the sill clearance being smaller than normal. This can be difficult to fix in the case of a masonry or steel stud construction because the frame can't be moved.

Thermomechanical Issues

Thermal bow is a temporary condition caused by the temperature difference between the outside and inside of the door. It is most often seen in exterior doors with direct sunlight rays on the exterior, but it can be a problem when air conditioning creates a huge temperature difference between the inside and outside of the door. The amount of bowing is contingent on the color of the door and construction, as well as the duration of exposure to direct sun rays, and temperature. It is also exacerbated by the density of the core inside the door. The issue is difficult to fix by changing the latch, strike or weatherstripping on the field. This is because one side of the door expands, while the other side remains normal.

double glazed window bow is to paint the doors with a light color, and then block the sun's rays from hitting the surface. In extreme circumstances, it could be necessary to install a retractable solar shade which can be lowered in the event of very hot weather.

Warping is another issue commonly encountered when it comes to solid doors. This is caused by changes in humidity or temperature on the opposite side of a door (as frequently observed in bathrooms or outside doors). The most likely reason for this is the rapid cooling or heating when air conditioners or heaters are turned on. The warp could cause the door to expand on one side making it difficult to close or seal. This expansion can also create clearance issues as the door moves away from the jamb seals. The most serious instances of this can require a modification of the jamb and/or door in order to allow it to clear the threshold.
