When properly executed, structures have a long service life. If there are deficiencies already during construction, then these lead to structural damage that affects functionality and durability. In conservatories, faulty building connections are one of the most common defects and structural damage, and removal is associated with high costs. Further weak points are sealing defects or defects in the roof structure.
Faulty component connections
Conservatories are usually added to the existing building at a later date. Since the conditions are often not optimal, problems can arise that have a negative effect on the functionality and tightness of the connections. Particularly noteworthy is the connection to the roof structure and the horizontal floor connection, as these are particularly stressed both statically and in terms of tightness. There are seldom standard solutions here, which makes it all the more important to adapt the design precisely to the existing on-site situation.
When the roof structure is connected to the wall, the expansion of the structure creates a movement that has to be absorbed by the permanently elastic sealant between the conservatory roof and the outer wall. If the connection is incorrectly made, the sealant will tear. To avoid this, the sealing joint must be underlaid with a PU foam cord.
The floor connection of the conservatory elements is difficult or impossible to access after the conservatory has been completed. Therefore, professional execution is particularly important.
Only a flawless seal guarantees that a conservatory is wind and moisture-proof and meets the requirements for impermeability and thermal insulation. Frequent mistakes relate to the use of the respective sealant and its installation.
The joint sealing tape used is not compatible with adjoining component connections to the outer wall, the tightness is not permanently secured and moisture damage and thermal bridges occur.
When using pre-compressed and impregnated sealing tapes, the wrong dimension is selected. When selecting the sealing tape, the tolerances specified by the manufacturer must be observed. When installed, the sealing tapes may exceed the minimum or maximum dimensions.
Self-cleaning glass reduces the maintenance effort in the conservatory. Due to the properties of the surface coating, it is not compatible with silicone sealants, the seal does not fulfill its tasks, moisture penetrates, the coating of the glass is attacked.
Defect on the conservatory roof
As a rule, conservatories are equipped with a mono-pitch roof, and often the roof also consists of glass surfaces. If too little or no inclination is selected here, this can lead to visual and functional defects:
The water does not run off or does not run off completely and it comes to a deflection if the roof is interrupted by rungs, real puddles of water and finally dirt or limescale deposits develop.
The inner sealing layer can fail, especially at intersections of the construction, and water enters the conservatory through the roof.
If multi-wall sheets made of acrylic or Makrolon are used, according to the manufacturer's instructions, a slope of 5 to 7 degrees must be observed so that moisture that penetrates through the open ends can dry off quickly.
And if you find that the conservatory roof has been damaged too much, you can look for replacement conservatory roofs Bristol. There are plenty of companies in Bristol that manufacture Replacement conservatory roofs, and fit that your existing conservatory area.
Find leaks in the conservatory
If water penetrates the conservatory, the point of entry is often not visible at first glance. A pressureless sprinkling test, which is carried out with a water/garden hose, helps here. Another option is ultrasonic leak detection. If the leak cannot be determined based on these measures or the cause cannot be clearly clarified, the component must be opened.
