If the cuts were not at right angles, then the points where the
cut siding planks meet and were installed had to be caulked because there would be excessive space between the joints.
If there was an error in the measurements then a whole siding plank or some portion of it could become
waste material which would drive up the cost of installation of the siding planks.
Therefore the prior art could not make very much use of every joint in the installation process which had been created as a factory end joint and which would provide for superior joints between butted siding planks.
The prior art also had the problem of holding accurate alignment around windows and
doors and other openings which might even require an installer to remove planks previously installed and reinstall them in order to achieve alignment at the top of a window, door or other openings when they came to the top of the window, door, or other opening and continued installing full length planks again after continuing installation over the window, door or other opening again.
Also in the prior art, the cuts of the siding planks had to be made at perfect right angles which can be very difficult to achieve on consistent basis for the joint of one siding plank to meet the next siding plank to which it is abutted.
If the cuts was not a perfect right angle, then the joint can be ragged and not provide a quality installation or may require that the joint be caulked.
If the angle was too great off 90 degrees it could even cause a portion of the end to miss landing on the stud, which could leave a gap in the siding which would be difficult to fill with caulk.
In any event it required additional labor to
cut and then caulk such joints when necessary and it drove up the prior art cost of installation in both labor and materials costs.
Many of the prior art devices for installing planks required a separate device for each size plank to be installed and on the larger planks the prior art devices were relatively heavy and cumbersome in size.
Therefore a worker could not carry very many of them up the scaffolding to be used in the installation process, which meant that the worker had to make frequent trips during the installation process for additional prior art devises to be used in the installation process.
Further many of the prior art devices could only be installed in one direction because of the way they were designed with a fitting to receive a plank and the other end of the devise was designed to be hung on the plank to which the plank was to be installed.
This step of having to orient the prior art device, however took up valuable time and increased the cost of installation.
This at least double step of first nailing the prior art device and then inserting the material to be installed added additional time and labor expense to the cost of installation of a job.
In the case of having to install the prior art device first and then insert the siding plank or roofing material not only increased the cost but required the installer to first accurately install the prior art device for proper alignment and overlapping arrangement which again took extra time and increased the cost of installation.
While there are many prior art devices which utilize clips most of those devices did not provide a finished product which achieved an
interlocking relationship between the planks such that a prior art plank or plank
system installed created an overall interlocking
system which resisted
storm and
wind damage.
Also the prior art devices did not provide any means of draining rainwater which might be blown up under the planks and / or dripped down behind the wall onto the prior art devices.
Therefore with no drainage and continual
wetting in the prior art devices, the prior art devices experienced
corrosion of the devices as well as damage to the siding.
As a prior art device required considerable more
cutting of the planks therefore there was more labor costs associated with the process of installing the planks with the prior art devices.
Also because of the increase
cutting of planks in the prior art there was considerably more waste of plank materials which raised the cost of the finished product.
Further the prior art devises would only occasionally cause the factory created end joints to meet for creating a joint, if they managed to hit perfectly on a stud at 1 / 2 its thickness and then leave 1 / 2 of its thickness for the factory created end joint of the next piece, thus in most cases forcing a
cut to be performed to hit the stud accurately for fastening its end to the stud.
