How to Avoid Door Fitting Bow Problems

Installing bow windows is an enormous project that should be handled by professionals. It involves extensive framing and the construction of a header.

Bow windows must be fitted with arrangements to provide weatherproof sealing and efficient protection of the doors' interiors from damage. Inspections should be documented at intervals of no more than monthly.

Thermal Bowing

The difference in temperature between the outside and inside of a door could cause one side to expand and swell while the other is in more stable levels. This is known as thermal bowing. It can cause difficulty to latch hardware or open the door. Thermal bowing is not permanent. It can be corrected by adjusting the latch and strike hardware or using a lubricant that helps the metal parts slide easier.

Bowing caused by thermal is also affected by the type of core in the door. Polyurethane or polystyrene insulated doors are more likely to bow because they cannot evenly distribute heat evenly throughout the panel, while a honeycomb core permits heat to flow more easily through the panels. The color of the panel may affect its thermal performance. Darker colors absorb heat energy more effectively, which can increase the amount of thermal bowing.


IMP representatives are well aware of the impact of thermal bowing on their products, and can provide customers with recommendations for the proper installation. The IMP representative can make calculations based on project location and performance requirements, aesthetics and building structure as well as final use to eliminate the issue of door fittings bowing.

Many homeowners notice their solid wooden doors starting to warp as they transition between cold and hot climates. This is caused by an increase in humidity and differences in temperature between the outside and inside of the home. The warping is not a manufacturer problem and can be prevented by keeping heating and air conditioning vents from the doors. Another common issue with solid wood doors is door hinges that become stuck when they are closed and opened due to the different temperatures on opposite sides of the door. This could be due to moisture getting into the door through an unintentionally sealed frame or weather strip that is placed around the frame. Despite these problems, most solid wood doors can be salvaged by making some simple adjustments.

Clearance Issues

Problems with installation can impact the performance and fit of doors. One of the most crucial is edge clearances. This is the distance between the door and the frame head or jambs. If the frame or door is affixed to the jambs, head or any other doors, it is a problem of edge clearance and can cause friction that can damage the frames, doors, and hardware. This could be due to an incorrectly anchored frame in the wall or a mistake in the measurement of the head as well as the jambs, resulting in an edge clearance that is less than normal. It can be difficult to fix this in a masonry construction or steel studs because the frame isn't able to move.

Thermo-mechanical Issues

Thermal bow is a temporary condition triggered by the difference in temperature between the inside and outside of the door. This condition is most common in exterior doors that have direct sunlight rays on the surface. However, it can also occur when air conditioning creates huge temperature differences between the inside and outside of the door. The amount of bowing is determined by the color of the door it's made of, the construction, how long it has been exposed to direct sunlight and the temperature. It is also exacerbated by the density of the core inside the door. The issue is difficult to fix by adjusting the latch, strike, or weatherstripping on the field. This is because one side of the doors expands, while the other side remains normal.

An alternative that is more durable is to paint the doors with a light hue and keep sun's rays away from hitting the exterior. In door fitter bow , it may be necessary to install a retractable sun shade that can be lowered in the event of extreme heat conditions.

Warping is a different issue that occurs with solid doors. This is caused by a change in temperature or humidity on the opposite side of the door (as often seen in bathrooms or exterior doors). This is usually caused by rapid heating or cooling, which occurs when air conditioners or heaters are switched on. The warp can cause the door to expand on one side and could be difficult to close or seal. This expansion can also cause clearance issues, since the door is further from the seals on the jamb. The most severe cases of this can necessitate a modification to the jamb or door to allow it to clear the threshold.
