Some projects require a system providing higher protection against sliding snow, for example in areas with heavy snowfall. Roofs with solar panels also need a higher level of protection to stop snow below the last panels from sliding off. The RoofTech Double-Tube holder, material stainless steel, will be fixed on two S-5! Mini-Clamps and common 32/2mm-tubes will be sliding into the tube holder. The advantages are:
Material: 3mm Stainless Steel – very strong and suitable for all metals.
Easy fixed on two S-5! Mini-clamps with the M8-screws on top.
The lower pipe lies optimal direct on the seam.
And the top pipe is 16 – 20cm high above the seam.
RoofTech Double-Tube snow retention: easy to install and high holding strength.
The stainless steel RoofTech Double-Tube holder can be fixed on all S-5! Mini-clamps (also B-Mini for copper roofs !).
To prevent the ice from sliding beneath the snow guard tube we recommend to install ice stoppers.
We offer optional different ice-stopper, depends to the seams, which will be fixed between the lower pipe and the roof.
A professional snow guard is used for traffic safety and protects pedestrians and objects from falling snow and iceloads. The dimensioning and design of a snow guard system depends on the building use and location as well as the roof shape and pitch. The responsibility for this always remains with the builder or building owner. RoofTech GmbH and S-5!® – Metal Roof Innovations Ltd. generally recommend that the snow guard system is planned and dimensioned by a qualified professional.
Double tube snow guard rows should only be used in conjunction with snow guard rows above them because of the leverage effect.
Loosely pre-assemble the double tube holder with the M8 stainless steel screws through the slotted holes on two S-5! mini clamps suitable for the fold type.
Position the double tube holder with the mini clamps correctly on the seam.
Insert commercially available 32/2 mm tubes through the two holes and align the snow guard row.
The set screws of the S-5! mini clamps must be tightened according to the mounting instructions of the S-5! clamps to the seam with a tightening force of 15-17 Nm. Some types of folds and clamps cannot be mounted on the clips or holders. Please note also the installation instructions of the S-5! Clamps.
Tighten the M8 stainless steel screws with 30 Nm onto the S-5! Clamps to tighten the double pipe holders!
Finally fix the S-5! Mini clamps.
To prevent lateral displacement, each tube must be fixed once to one of the double tube holders with a screw through the screw lug.
Between the pipes (recommended length max. 3m) in a row, a sufficient distance must be provided for the thermally induced length change of the pipes.
In order to prevent ice or snow plates from slipping off, additional ice stoppers (1 to 2 per share, spacing 30 cm) should be fitted between the lower pipe and the roof skin (available as an accessory).
General Notes for Planning Snow Retention with S-5!
Please observe the country-specific legal and official regulations for snow retention. Depending on the location of the building, height of the terrain above sea level, roof shape, roof pitch, type of metal roof and the respective holding strength of the S-5! clamps, the suitable snow guard systems must be professionally calculated and designed.
With the snow guard system, the push effect of the snow lying on the roof is to be prevented by one or more rows of snow guards covering the entire area. The decision on the dimension and design of a snow guard system depends on the use and location of the building, and responsible therefor is always the owner of the building. In case of doubt, a structural engineer should be consulted to determine the loads and the dimensioning of the snow guard system.
The respective product installation instructions must always be observed (included in every box and with every delivery or please request or download from our homepage). During the entire installation period, it must be ensured that at least one copy of the relevant installation instructions is available on the construction site to all those involved in the installation and that it is strictly observed during installation.
Installation with our products should only be carried out by specialists and specialist companies with qualifications for the respective installation and with experience in working on roofs. During installation, the warranties of all trades involved and of the roof as well as the respective regulations for work on roofs must be observed (e.g. the use of fall protection, scaffolding with safety gear from an eaves height of 3 m, accident prevention, insurance, etc.). The presence of two persons is mandatory for the entire assembly process in order to be able to guarantee rapid assistance in the event of an accident.
In the case of non-observance of our installationy instructions, or assembly of our products with components of competitor and in the event of the use and combination of further components which were not purchased from us, we shall not accept any liability for any resulting defects and damage. The warranty is excluded in this respect.
Assumption is that the determination has been made that the roof to which the snow retention and the S-5! clamps will be attached is structurally adequate. Any loads imposed on the snow retention and S-5! clamps will be transferred to the roof panels. Panel seams must have sufficient flexural strength to carry these loads. Roof panels must also be adequately attached to the building structure, and the structure must be sufficient to carry these loads. The makers and distributor of the RoofTech and S-5! products make no representations with respect to these variables.
It is the responsibility of the user and/or installer to verify this information, or seek assistance from a qualified design or structural professional, if necessary. The user and/or installer of these parts is responsible for all necessary engineering and design to ensure the snow retention and S-5! clamps have been properly spaced and configured. Due to the many variables involved with specific products, climates, snow fall and melt phenomena, and job particulars, the manufacturer and supplier cannot and does not express any opinions as to the suitability of any RoofTech- and S-5!- assembly for any specific application and assumes no liability with respect thereto.
The lowest snow guard row should generally be installed about 20 to 25 cm from the edge of the eaves. If additional rows of snow guards are provided, the roof surface should be divided into sections of approximately equal size in order to achieve an even load and the best possible effectiveness. Double tube snow guard rows should only be used in conjunction with snow guard rows above them because of the leverage effect.
The material properties of the respective metals, the combination with each other and the installation instructions and regulations of all manufacturers involved (including those of the metal roof) must be observed.
The user and/or installer bears also the responsibility not only for the professional installation, but also for the roof on which he is mounted. The user and/or installer must always clarify in advance the application possibilities and application of our products in connection with the other used materials and products at the single project. The snow guard systems are not suitable as fall protection.
Please note the installation instructions of the respective S-5!® clamps and the other products used! Mounting the S-5!® clamps take care that the set screws and bolts are tightened with the right screw tension as written in each installation instruction (available in all boxes, on the homepage of RoofTech: www.rooftech.de and S-5!: www.s-5.com or please send us an inquiry). When tabled values are used, screw tensions should be verified and factors of safety should be used as appropriate. If you are missing important and necessary information, please request it from us.
The material properties of the respective metals, the combination with each other as well as the installation instructions and regulations of all manufacturers involved (including those of the metal roof) must be observed. If technical details are not described separately, this does not release the company carrying out the work from its obligation to check the individual case and clarify the correct technical facts beforehand.
The installation of our products should only be carried out by qualified and professional specialists with experience in installing on roofs. During installation, the warranties of the installations, snow retention, solar system, etc. and the roof as well as the respective regulations for work on roofs must be observed (e.g. the use of fall protection, scaffolding with safety gear from an eaves height of 3 m, etc.). The presence of two persons is mandatory for the entire installation process in order to ensure rapid assistance in the event of an accident.
