Whether it is an aluminium, PVC or aluminium - wood window or door, regardless of the type (open joint, thermal break, fixed, hinged or sliding), every construction must be done in a workmanlike manner, starting with highest quality materials.
This section illustrates the main aspects of the production of an efficient window.
CLL has always focussed the production of TECNO systems on quality, providing its customers with primary Anticorodal aluminium extruded products.
Let's see the steps involved:
- The raw extruded profile is obtained from initial production in the drawing mill.
- The bar must still be treated to obtain the final surface finish;
The bar can be painted or oxidized depending on the customer's request.
Even the surface finish has to meet high quality standards to guarantee a product that lasts over time.
CLL collaborates with the best in the field for this process, providing durable goods, regardless of their forms.
- The thermal break is made by inserting polyamide rods during the assembly process at our plant.
This step doesn’t take place in the case of "cold" profiles.
- The article is then ready for processing by the manufacturer.
CLL includes data sheets in its technical catalogue with the Cutting lists of profiles; the data sheets are subdivided by door/window type.
The cutting lists allow the manufacturer to check that material to use is correct, and optimise it if necessary.
The lists should be checked before processing, as the data has been obtained from theoretical calculations.
TECNO systems have been designed as an assortment of profiles, accessories and gaskets in compliance with regulations, requirements and recommendations that currently exist in Italy and that define the dimensional limits.
It is absolutely essential that original TECNO goods are used and that the manufacturing and application processes indicated in the catalogues are performed.
Installation and setup.
The installation of a door or window is of the utmost importance, since it directly affects the definition of door or window performance.
In fact, if the door or window is not installed correctly, its performance will deteriorate.
Unfortunately, to date, no actual regulations identifying a "workmanlike manner" have yet been approved; in the same manner installation cannot be determined only by experience of manufacturer.
There is no doubt that an excellent knowledge of the characteristics of the door or window being installed is not to be underestimated; Thanks to these skills, the fitter is able to improve, modify or rectify any problems encountered during installation, ensuring a functional and efficient product for the customer.
The steps to be performed for optimum installation can be summarized as follows:
This must be performed in the best possible manner to avoid damage to the door or window that would subsequently affect its efficiency and appearance.
- Packaging quality:
Packaging should be positioned differently in relation to surface points; the use of polystyrene or cardboard corners is recommended on the edge of the frame, to eliminate rubbing with other surfaces; the use of bubble wrap and protective pads is recommended on glass to avoid damage.
- Installation on site:
This should be performed in the safest manner possible, using, as far as possible, suitable equipment and supports to protect the operator from heavy physical stress.
- Precision and installation:
In addition to accuracy during installation, the fitter must use high-efficiency products for the thermal insulation and soundproofing of the door or window to be fitted. In fact, vapour/air sealing films, sealants and polyurethane foams designed to absorb moisture and many other products are available to aid the installation of doors and windows and promote their long term integrity.
- Customer relations:
CLL has always considered its relationship with customers as extremely important, meeting their requirements in a precise, consistent and reliable manner, gaining an ever-expanding customer portfolio.
Quite often the end customer, the user, does not know of the existence/absence of regulatory standards for installation; the "workmanlike" manner is conventionally determined by what the user sees and aesthetically evaluates when the work is completed.
That is why CLL submits a simple, concise and comprehensive project development so that no doubts remain unsolved.
- Cleaning of the site after installation:
We believe it is good practice and respectful of the operator to leave the workplace as clean as possible, disposing of waste materials, but also cleaning product residues that require the use of appropriate solvents which do not damage existing surfaces.
