Caulking requires specific skills; both in the field of news
technologies (infrared thermography) than in the application of sealants and seals.
Caulking refers to all openings in a dwelling such as doors and windows.
We’ll talk below about the sliding windows that are usually found in
verandas and pergolas.
Quality caulking is necessary to preserve their functionality: better thermal insulation, sound, good waterproofing and more safety. A large sliding door is particularly exposed to the elements and its opening and closing system can undergo rapid deterioration.
The caulking of a sliding glass door is therefore a meticulous and delicate operation that must be carried out by a professional.

Isolation of a bay window: the work of the caulking specialist
Before any intervention, the professional, an expert in caulking, makes a diagnosis of the condition of
insulating the sliding glass:
- State of the joints
- Thermography to detect air infiltration (if necessary by a recommended expert)
- Abnormal humidity
- Moisture, insects…
In sliding systems, it is particularly air and water infiltration that are
Once the problem is diagnosed, the technician prepares the work surface. It cleans various dust and dirt. The flaps are then deflated and placed separately. Before fixing the frame, it’s time to lay the joints.
To do this, the technician uses special and adapted sealants to withstand moisture. The seals are applied all around for better insulation. Once this is complete, the frame remains to be fixed with the bubble level for a perfect installation.
The second stage takes place after the installation of the bay window. The caulking expert fills the gaps with an insulating sealant. For good adhesion and to consolidate the entire pose, it is necessary to take into account the drying times between each layer.
It is at this very moment that all the know-how and knowledge of the professional, window installer and caulker, come into play!
Different types of floor-to-ceiling sealants
There are several types of professional seals and seals. It is important to use high quality materials for good durability. The Adfast range of sealants are the latest generation silicone seals.
Sonneborn’s NP1 is a product that optimizes the thermal and phonic insulation of your sliding window door.
These sealants are used by experienced caulking professionals who have all the know-how and training to handle these products. As a result, your floor-to-ceiling windows will have a longer lifespan.
What caulking area to insulate a veranda
For a better result, you can multiply the seal areas. There are three main locations that guarantee good caulking.
- First, the inner joint
It avoids heat loss by avoiding air leakage to the outside. It must therefore be
particularly airtight. An acrylic seal can do the trick.
- The median joint
The sealant is placed between the frame and the masonry. There is a hollow between the two structures. This
space must be filled entirely with an insulating sealant. The challenge is not to let
empty areas. This is why the solution of a foam is well adapted because it fully fills
space. Only small downside: it is not recommended for allergic people. In this case, the
technician will offer other insulating products or plugging materials.
- The outer sealant
This sealant must be placed with great care. Indeed, this seal insulates you from the weather, rain,
wind and cold. It must therefore be particularly resistant. The outer sealant plays an insulating role
but also to protect materials. The silicone seal is recommended as well as a film or
