Why protect · Construction and Industry
The scratch on the profile happens at assembly. The chip in the glass, when the scaffolding goes up. The stain on the floor, when the plaster coat goes on. These are processes that have to happen, and every one of them passes over a finish that is already done.
The problem
Scratches and knocks on site
Glass, anodised aluminium, stainless steel and stone are installed early and handed over late. In that interval come the tools, the scaffolding, the rubble and the movement of site personnel.
Chemical contamination
Cement, plaster, paint, sealant and solvent landing on a finished surface. Removing them costs more than the material, and sometimes they do not come off: the part is replaced.
Delays from repair work
A damaged part is not simply replaced. It has to be coordinated with the supplier, the dispatch has to be waited for, the part refitted, and the handover date moves. The cost of the delay is rarely budgeted.
The cost
It is paid for with six things. This is the list; you put in the values, with the prices from your own project. Add up the column and compare it against what it costs to cover the same batch with film.
| Item | What it includes | Your cost |
|---|---|---|
| The part | Glass, profile, sheet or worktop that has to be bought again | — |
| The return freight | Sending the damaged part back and dispatching the new one | — |
| The reinstallation | Labour that had already been paid for once | — |
| The site visit | Diagnosis, report and coordination with the supplier | — |
| The delay | Days the handover slips, and what each one costs | — |
| The conversation | What the claim weighs on the next purchase the client makes | — |

what it costs to deal with a claim, against what it costs to protect
A claim from the end customer is not paid for with the part. It is paid for with the part, the return freight, the reinstallation, the site visit, the delay in handover and the conversation with the customer. The film is the cheapest link in that whole chain.
Figure from Martínez Navas SAS
How we do it with you
An adviser from Martínez Navas takes a real batch from your project —a tower, an order, a dispatch—, puts the prices you work with into each line of that table and compares them against the cost of the film for that same batch. If the sum does not add up for you, we say so.
The savings
Four cost areas that come down when the material arrives covered. These are the savings Martínez Navas reports across its own client base in Colombia.
80%
less material replacement
Protected glass, aluminium profile and stainless steel reach the site and are handed over in good condition, with no replacement for damage.
60%
less cleaning time at the end
The film acts as a barrier against cement, paint and dust. When it comes off the surface is clean, with no specialist cleaning process.
40%
lower warranty costs
Fewer warranty claims for damaged finishes, because the project is handed over with the material in good condition.
100%
covered from the machine to handover
The part leaves the line covered and is uncovered on handover day: the assembly, the handling and the dispatch all happen on the film, not on the finish.

Results
Case 01 · Apartment developer, Bogotá
The situation
On a 200-apartment project, 15% of the windows arrived damaged at final handover for lack of protection during the build.
With PDS film
With clear PDS film on all the glazing from installation onwards, the damage rate fell below 1% and more than $45 million COP in replacements was avoided.
Case 02 · Stainless steel company, Medellín
The situation
Industrial kitchen equipment was reaching the end customer with factory scratches, which meant constant returns and claims.
With PDS film
Applying the film from the production line onwards eliminated scratch claims and packing time fell by 30%.
Cases supplied by Martínez Navas SAS
The difference
Without protection
With PDS film
Who protects
Housing where the window units, the floors, the façade and the joinery have to reach the final buyer intact.
Shopping centres, offices and hotels, where the finish is part of the value of the property and damage shows on the first day of operation.
Production lines where the part already carries added value and still has to go through assembly, storage and dispatch.
Anyone who moves flat glass, metal profile, panel and finished product, and answers for the state it arrives in.
