FAQ

1. What is STRAMA Panel System®?

It is a unique and the world’s only facade panel system that comes together with mounting rails in the same package. One package contains 3.2 sq. m. of facade cladding, it weights less than 20 kg and can be taken to the site in a passenger car. It is a perfect product for large home improvement stores, construction material wholesale dealers, contractors and DIY. It is a 21st century product.

 

2. Why are STRAMA® Panels sold in boxes?

  • For easy transportation and storage.
  • 2 in 1. The box contains the complete installation kit (panels with mounting rails SEMS-LM), which is particularly convenient for the DIY market.
  • Panels are protected against damage during storage, handling and transport, all along the entire supply chain.
  • The packaging itself serves advertising purposes and ensures better in-store visibility of the product.
  • Since the box weight is up to 20 kg, it can be easily handled in stores and warehouses, without violating health and safety regulations.

 

3. Is it easy to install STRAMA® panels on the facade?

Yes, it is. Already at the stage of designing the package we thought about do-it-yourselfers and put the panels into a convenient box together with mounting rails SEMS-LM. STRAMA® panels are easy to install for any averagely skilled do-it-yourselfer. Information about the necessary tools can be found in questions 31 and 32, instruction manuals are available on our website.

 

4. What makes the front site of STRAMA® panels different from other facade panels?

Wood and Colour Design series are coated with films by Renolit®, the world leading manufacturer. This choice of the material makes the facade resistant to UV radiation, and graffiti can be removed without much effort.

Clinker and Stone Design series are coated with resin-based imitation of brick and stone. It is a composition of acrylic resin, dyed quartz sand with an addition of biocidal agents, Teflon and waxes that form a hydrophobic surface. Their advantage over natural products is that they can be cut and bent to shape, e.g. at corners, whilst maintaining resistance to mechanical damage, moisture and UV radiation. All STRAMA® panel claddings can be easily repaired in case of damage (see also questions 16, 17, 18).

 

5. What is included in the STRAMA® Panel System (SPS)?

The STRAMA Panel System® (SPS) includes several product lines, which can be combined freely on one fixing system.

  • STRAMA® panels together with their form dedicated to simple, three-dimensional and efficient connections, in keeping with technological requirements contained in instruction manuals and certificates.
  • SEMS®, or STRAMA Easy Mounting System. Designed and patented by STRAMA, SEMS® reduces room for error during STRAMA® panels installation and maintains facade properties in compliance with the design and certificates.
  • The box, containing all materials necessary to proceed with installation.*

 

All elements of the SPS are integrated and allow installation on different architectural elements of houses, pavilions, public buildings. Examples are shown in our photo galleries.

Approx. 6 spacers are necessary per 1 sq. m. of the facade.

 

* Except for spacers that must be ordered separately by the customer.

 

6. What is SEMS®?

SEMS® = STRAMA Easy Mounting System, an integrated STRAMA® panels mounting system, engineered and patented by STRAMA. SEMS® reduces room for error during STRAMA® panels installation and maintains facade properties in compliance with the design and certificates.

 

7. What is included in the SEMS®?

The SEMS® includes:

  • Mounting rails SEMS-LM dedicated to STRAMA® panels installation complete with DryTherm® insulation system or directly to the wall,
  • SEMS-KD distance spacers with varying lengths, depending on the facade’s intended function (smoothening out uneven walls, covering up thermal insulation or improving visual appeal). Spacers are ordered optionally by the customer.
  • Aluminum and steel profiles (SEMS-JA and SEMS-JS) for finishing certain architectural elements, depending on the panel’s decor. Finishing profiles are ordered separately by the customer.
  • Repair kit SEMS-ZN dedicated to finishing of the finishing ending panel (finishing strip) on the facade of the building and for repairs of the damaged panels. More in questions 16-18.

 

All metal SEMS® elements are galvanized.

 

8. Why is the mounting rail made of galvanized steel rather than of timber?

  • Steel is more durable than commonly used timber battens.
  • Timber battens are sometimes made of waste timber with varying moisture content and may become deformed.
  • SEMS-LM mounting rails come with ventilation openings ensuring air flow under the profile and error-proof fastenings for panel installation.
  • Fastenings on SEMS-LM mounting rails also provide vertical expansion gap between panels.

 

9. What does the starter trimm look like in the STRAMA Panel System®?

Our system does not use dedicated starter panels (starter trims). The lowermost row of STRAMA panels, installed on SEMS-LM steel mounting rails at the bottom of the facade serves the function of a starter panel. Installation of the first row of panels does not differ from installation of the remaining rows.

 

10. What does the finishing panel (trim) look like in the STRAMA Panel System®?

Our system does not use dedicated finishing panels (trims). The uppermost row of STRAMA® panels, installed on SEMS-LM steel mounting rails serves the function of a finishing panel. Panels are mounted to SEMS-LM mounting rails by means of steel screws in places where resin has been previously removed to make room for the screw’s head. Subsequently, fixing points are patched up with resin (in case of Clinker Design and Stone design) or with corresponding foil (Wood Design and Colour Design).

 

11. Are there dedicated inside and outside corners in the STRAMA® system?

Our system does not require dedicated inside and outside corners.

Corners are formed from STRAMA® panels. To do so, a panel must be cut to size and then milled so as to remove the panel’s chamber walls at a width of approx. 12mm and to a depth of 7mm. Subsequently the milled part of the panel must be heated up and bent to shape. Wait a few minutes until the PVC material solidifies and install it on the wall.

On request, we provide aluminum and steel profiles (SEMS-JA and SEMS-JS) in a number of attractive color versions for finishing various architectural elements.

 

12. How should inside and outside corners be formed?

A panel must be cut to size and then milled so as to remove the panel’s chamber walls at a width of approx. 12mm and to a depth of 7mm. Subsequently the milled part of the panel must be heated up and bent to shape. Wait a few minutes until the PVC material solidifies and install it on the wall.

 

13. Can STRAMA® panels be installed on rounded surfaces?

Yes, it can. Through cautious bending of the panel on curvatures with radius no less than 40 cm.

 

14. Can STRAMA® panels be used as a facade for thermal insulation?

Yes, they can. Thermal insulation together with STRAMA® facade is installed using SEMS-KD spacers. SEMS-KD spacers are available in a number of versions, differing in terms of both length and mounting method, depending on insulation material thickness. The insulation system could be installed also with use of "Z" trims, available in DIY shops.

 

15. How can I install the facade on uneven walls?

The facade’s frame is installed using SEMS-KD spacers. The problem of uneven walls can be solved by using SEMS-KD spacers of varying lengths (minor unevenness can be fixed by means of shims or panel cut-offs inserted under mounting rails in the bolting area).

 

16. What is the SEMS-ZN repair kit?

For Clinker Design and Stone Design facades there is a dedicated container with resin whose color matches the facade, together with a small putty knife. For Wood Design and Colour Design we recommend patches made of film corresponding to the panel’s decor. More information in questions 17 and 18.

 

17. How can I fix damages on Clinker Design and Stone Design facades?

Minor damages can be fixed using the method dedicated for patching up finishing panel mounting. The SEMS-ZN repair kit will be necessary. Apply appropriately colored resin from the repair kit to the damaged spot using the putty knife provided and leave to dry. In case of bigger damages panel replacement is recommended. A damaged panel can be replaced without uninstalling the facade in whole or in part. In more challenging situations please contact STRAMA.

 

18. How can I fix damages on Wood Design and Colour Design facades?

Minor damages can be fixed using the method dedicated for patching up finishing panel mounting. The SEMS-ZN repair kit will be necessary. Apply an appropriately colored patch of film on the damaged spot.

In case of bigger damages where panel replacement is necessary please follow the manual available on our website. Panel(s) can be replaced without uninstalling the facade in whole or in part. In more challenging situations please contact STRAMA.

 

19. How are the panels joined vertically?

STRAMA® panels are joined by overlapping. One advantage of STRAMA® panels is that the panel is simultaneously mounted to the mounting rail SEMS-LM. More details are available in an instruction manual available on our website.

 

20. How are the panels joined horizontally?

The advantage of Clinker Design and Stone Design panels is that they can be joined horizontally without any accessories and in such a way that the joint is invisible on the outside. The number of panels that can be joined in this way is unlimited.

For Wood Design and Colour Design we recommend steel (SEMS-JS) or aluminum (SEMS-JA) trims for horizontal joints. More details are available in an instruction manual available on our website.

 

21. Do STRAMA® panels require dilatation?

Yes. Between the panels 125 cm long, dilatation of at least 3 mm is required (Clinker and Stone Design). With longer panels we increase dilatation, for example, in Wood Design Panel 240 cm we use dilatation 6 mm.

 

22. Does STRAMA Panel System® require an air ventilation?

The natural feature of PVC panels is the accumulation of heat energy. Failure to vent the ventilation gap between the wall or thermal insulation and the panels may lead to damage to the panels.

Keep the ventilation gap behind the panels at least 2 cm.

 

23. Why is there so little waste from the STRAMA Panel System®?

Clinker Design and Stone Design panels come in standard length of 1250mm. They are joined horizontally without any accessories. Cut-offs are used as starters in the next layer or as finishing materials around windows, doors, corners and other building elements.

Wood Design and Colour Design come in lengths ordered by the customer, to avoid unnecessary waste. Cut-offs can also be used as finishing materials around windows, doors, corners and other building elements. As a result, the waste amounts to approx. 2 per cent.

 

24. How can I calculate the cost of facade material if I use the STRAMA® system?

STRAMA recommends taking a precise measurement of the surface to be clad with STRAMA® panels, together with internal surfaces in window and door openings, recesses, arcades, etc. Then you should calculate the number of spacers and steel tapping screws, as per the instruction manual. You will need approx. 6 spacers per 1 sq. m. of the facade. Once you know your quantities, multiply them by their prices and add them. Please allow for approx. 2 per cent waste, depending on the complexity of your facade.

 

25. How can I calculate the cost of labor necessary to install STRAMA® panels?

A trained installer or skilled do-it-yourselfer can install 5 to 30 sq. m. of the facade per day. Productivity will depend on facade complexity. Even walls with no architectural elements are very easy to work on. Productivity decreases in proportion to the complexity of preparatory works and the number of small surfaces that need to be covered.

 

26. How does the cost of STRAMA® system materials compare to the cost of other facade claddings?

To compare the cost of STRAMA® system materials with competitive solutions, we recommend making a cost estimate for the entire surface to be clad together with all accessories necessary to install the cladding around all architectural elements (STRAMA® vs. competitive solutions).

It would be a mistake to compare the price of 1 sq. m. of STRAMA® panels against the price of 1 sq. m. of a competitive material. A vast majority of commercially available systems require using a broad range of accessories supplied by the manufacturer. Some of them must be bought externally. In advertisements, leaflets and other publicity materials of competitive panels, the cost of accessories is either mentioned only briefly or omitted altogether. In fact, they can be a major cost component, increasing the price of material necessary for a single house by 30% or more.

 

27. How does the cost of STRAMA® system compare to the cost of a clinker brick facade?

The cost of STRAMA® panel facade is approx. 30 per cent of the cost of a clinker brick facade (in Poland).

 

28. What is USP?

USP is Unique Selling Proposition. Most of STRAMA® system advantages are unique, which means that similar features cannot be found in competitive products, making them a unique advantage for customers who purchase STRAMA® panels.

 

29. Where can I order STRAMA® panels?

Directly from STRAMA and from its distributors.

 

30. What tools are necessary for DIY installation of STRAMA® panels?

An angle grinder with a diamond disc for cutting panels and a metal cutting disc, a screw gun, a percussion drill, a heat gun, a leveling string, spirit level, tape measure, try square.

 

31. What tools are recommended for professionals?

An angle grinder with a diamond disc for cutting panels and a metal cutting disc, a screw gun, a percussion drill, a heat gun, a leveling string, leveler, tape measure, try square, metal cutting shears, a small table saw with a diamond disc, a milling table for panels.

A dedicated milling machine for making corners is available from STRAMA.

 

32. How to wash STRAMA® facades?

STRAMA® facades are best washed with a pressure washer. For more persistent dirt use a hard brush and a water solution of household cleaning agents. Do not bleach.
