5 Laws That'll Help Industry Leaders In Door Fitting Bow Industry
How to Avoid Door Fitting Bow Problems

Bow window installation is a huge project and should only be carried out by experts. It involves a lot of framing and construction of a window header.

Bow windows must be fitted with arrangements to ensure weatherproof sealing and effective protection of the doors' interiors from damage. Documented inspections should be carried out at intervals that do not exceed each month.

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 an optimum level. This is known as thermal bowing. It can make it difficult to latch hardware or open the door. The bowing caused by thermal is not permanent. It can be corrected by altering the latch and strike hardware, or by using a lubricant to help the metal parts slide better.

The bowing of thermal energy is also influenced by the type of core that is used in the door. Polyurethane and polystyrene doors are more likely than honeycomb core insulated doors to bow due to their inability to evenly distribute heat throughout the panel. In addition, the color of a door also has an effect on its thermal properties. The darker colors absorb more energy, which can lead to thermal bowing.


IMP representatives can provide suggestions on how to install their products correctly. They are well-versed in the effects of thermal bending. The IMP representative can perform calculations based on the project location, aesthetics, performance requirements and building structure as well as final use to eliminate the issue of door fittings bowing.

Many homeowners notice their solid wooden doors beginning to warp as they transition between cold and hot climates. This is due to changes in humidity levels and the temperature differences between the outside and inside of the home. The warping is not a manufacturing issue and can be avoided by keeping heating and air cooling vents away from doors. The door hinges can also get stuck when they are closed and opened due to the temperature difference on the opposite side of the door. This could be due to moisture entering the door through a poorly sealed frame or weather strip around the frame. Despite these issues, the majority of solid doors made of wood can be repaired by making a few minor adjustments.

Clearance Issues

Installation issues can affect the fit and function of doors. One of the most critical is edge clearances. This is the distance between a door and the frame head jambs or head or between the two leaves of a pair. If the frame or door is affixed to the jambs, head or any other doors, it is a problem of edge clearance and can result in friction that can damage the doors, frames and other hardware. This could be due to an improperly anchored frame on the wall or a mistake in the measurement of the head as well as the jambs, which results in the sill clearance being 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 Problems

Thermal bow is a temporary condition caused by the difference in temperature between the inside and the outside of the door. It is most often observed in doors that have direct sunlight rays hitting the surface, but can be a problem when air conditioning creates a significant temperature difference between the inside and the outside of the door. The amount of bowing is determined by the color of the door and its construction, as well as the amount of time it has been exposed to direct sunlight and also the temperature. The structure of the core inside the door can also exacerbate the problem. It is difficult to remedy by adjustments to the strike, latch or weatherstripping in the field because the issue is the result of one side of the door expanding, while the other is in a normal state.

An alternative that is more durable is to paint the doors with a light color, and then keep sun's rays away from hitting the exterior. In extreme circumstances, it could be necessary to install a retractable solar shade which can be pulled down in the event of very hot conditions.

Another issue that can be encountered with solid doors is warping. This could be caused by changes in humidity and different temperatures on opposite sides of the door (as is usually seen in bathrooms or exterior doors). This is usually caused by a rapid cooling or heating that occurs when heaters or air conditioners are switched on. The warp could cause the door to expand to one side making it difficult to seal or close. The expansion may also create clearance issues as the door moves further away from the seals on the jamb. In sash windows bow or door may need to be altered so that the door can move away from the threshold.
