"Constructive features and advantages of the double fold from LATIVA"

Maximum water resistance and reliability

The "double fold" system is designed so that the individual metal sheets overlap and are fastened without the use of visible fasteners. The resulting seam guarantees absolute waterproofing, which significantly extends the lifespan of the roof and the protection of the building.

Long shelf life and practical application

By choosing a double seam from LATIVA, you receive a product whose service life exceeds 50 years with proper installation and maintenance. In addition to residential and administrative buildings, this type of seam roof is suitable for buildings with architectural features such as churches, museums, monasteries, and other buildings with architectural identity.

Minimal slope for installation and flexibility in design

A major advantage of the double seam is that it allows installation on roofs with a slope of only 3 degrees, making it suitable for almost any type of construction. Furthermore, the flexibility of the technology allows for the installation of the double seam both in a classic linear execution towards the eaves and in the form of metal tiles, slates, or metal shingles.

Exceptional selection of materials and finishes

"Our double fold proposals include a variety of materials, among which:"

• Steel and galvanized metal: good durability, resistance, and cost-effectiveness;
• Aluminum sheets: lightweight and plastic, with anti-corrosion properties;
• Copper and zinc-titanium sheets: premium materials with the highest durability and longevity;
• Stainless steel with polymer coating: a stylish and UV-resistant choice for a beautiful appearance.

Disadvantages and features related to the double seam

"Like any established technology, the double seam has several features that should be taken into account when planning the roof structure:"

• Installation complexity: this type of roof requires precision, experience, and special skills for installation. Therefore, we always recommend choosing a professional team like that of LATIVA.
• Thermal expansion: the metal sheets expand and contract slightly due to temperature differences. The use of special movable clips effectively solves this problem;
• Noise during rain or hail: a well-designed installation with quality thermal and sound insulation, such as the use of mineral wool or a special membrane, completely eliminates this drawback.

What tools are needed for the installation of a double folded roof?

Unlike simpler roofing systems like Click Panel, where you usually only need standard tools, the installation of double standing seam requires a far more professional approach and a specialized set of tools:

• Folding machines: special equipment for shaping and bending the metal sheets that form the fold itself;
• Flat and angled pliers: designed for precise handling and processing of sheets;
• Set of specialized frames: slitting and frame for quality bending and gathering of the fold;
• Hand shears for metal: for precise cuts at a specific angle and shape;
• Movable clips: special elements that facilitate the free movement of sheets during thermal expansions;
• Fasteners and screws: weather-resistant.

The entire set of such tools needed for the proper execution of a double folded roof can be quite expensive, even exceeding the cost of the materials themselves. That is why most clients prefer to trust professional installation teams like LATIVA, who have all the necessary tools and expertise for reliable roof execution.

Steps and features for the proper construction of a double grill for a double seam

The correct construction of the main substrate – the double grid – is one of the most important stages in the preparation of the double folded roof. Here are some recommendations from the specialists at LATIVA:

• The first step is to install a high-quality waterproofing membrane that directs moisture away from the structure. It is installed loosely, with a minimum overlap of 15 cm between the individual layers.
• "To ensure proper ventilation, the installation of vertically positioned battens (5x5 cm) and horizontal battens (10x2.5 cm), securely fastened with screws, is required."
• The distances between the individual battens (about 20-30 cm) depend on the slope and size of the chosen material for the batten roof. The smaller the slope, the smaller the distance between the battens.
• With a smaller slope, it is often recommended to build a solid wooden or OSB sheathing for maximum stability of the roof structure.

Fixing metal sheets in a double folded roof – tips from LATIVA

"After the careful construction of the foundation, the installation of the metal sheets follows. When securing the folded panels, experts recommend:"

• Using movable clips that secure the sheets only on one side. This allows for free movement during thermal expansion and prevents potential deformation of the material;
• Professional folding of the double seam with a quality folding machine or special tool to ensure maximum tightness of the joints;
• Execution of the process according to the recommendations of the material manufacturer and the instructions specified in the documentation, to ensure optimal performance and durability over time.
