In this product group, we offer roof panels and profiles for their installation from the leading brand in the industry, GUTTA. The panels are light and flexible, suitable for roofs of any type. They improve the heat and sound insulation of the roof. They guarantee excellent ventilation, preventing the formation of condensation.
GUTTA sheets are resistant to strong winds and heavy loads - over 900 kg/sq.m. In addition to all the listed qualities, corrugated roofing sheets are also environmentally friendly, they do not contain asbestos and other harmful substances.
WHERE CAN GUTTA PLATES BE USED?
GUTTA bitumen corrugated panels are a stable, durable, easy-to-use and cost-effective building material. The corrugated sheets are suitable for roof slopes from 7 to 85°. Thanks to their large format /200x83 cm/, low weight, high elasticity, water resistance and resistance to various types of aggressive vapors and bases, these plates are perfectly suited for the construction of agricultural and industrial halls. In the private sector there are also a number of possibilities for their application, such as for covering garden houses and villas, as protection against wind and bad weather or lining car parks.
GUTTA panels can be cut with a hand saw, are fastened with self-tapping nails and can be easily installed by just one person. This gives even non-professionals ample opportunities to use them for various purposes. However, in all cases, the regulations of the building authorities, the accident prevention regulations and the technical guidelines of the trade union of roofers, as well as the roofing instructions, must be taken into account.
ADVANTAGES OF GUTTA PANELS
- The plate is waterproof and cold-resistant;
- The carrier material is a cardboard blank (semi-finished product) consisting of 100% recyclable material. It is produced using a multilayer technology similar to that used for the production of plywood;
- Ecologically clean production of starting materials from organic non-toxic fibrous raw materials without asbestos content;
- The untreated panels are completely soaked with harmless bitumen;
- For the attractive design of the roof, various coatings of vinyl-acrylic resin paints are optionally used;
- Corrugated bitumen panels are classified according to DIN 4102 as building material category 2 (with normal flammability) and are considered a soft roofing material.
HOW TO REPAIR A ROOF BY OVERLAYING WITH GUTTA PANELS?
Old or damaged roofs made of fibre cement boards, sheet metal or bituminous cardboard can be renovated quickly and inexpensively by covering them with GUTTA corrugated sheets. Due to their low weight, the roof panels have almost no effect on the statics of the roof structure. A counter batten is installed on the old roof layer, on which a transverse batten is placed, the GUTTA panels are laid and secured with self-sealing nails. Gable corners and ridge caps need only be added and the clean, solid roof will withstand all weather conditions for years to come.
WHAT DO WE GAIN FROM INSTALLING GUTTA PANELS?
- No need to remove and dismantle the old roofing material;
- The new covering is done quickly thanks to the large format of the material used;
- As a result of the "double covering effect", the sound and heat insulation properties and ventilation of the roof surface are improved;
- A lot of time and costs are saved.
HOW ARE GUTTA PANELS INSTALLED?
Local building regulations, accident prevention regulations and the technical guidelines of the trade union of roofers must always be observed, as well as the installation instructions for the panels. The GUTTA panel is a lightweight building panel and can only be walked on along the support beam in the area of the double skin. The distances to the substructure depend on the roof pitch and should not exceed approximately 600 mm.
The panels are laid against the direction of the main air flow from gable to gable and from eaves to ridge, blending with the width of the panel. They are then aligned at right angles to the end surface of the roof and fixed. If the panel is correctly laid, it is nailed on every second wave peak. In the area around the eaves, in the case of longitudinal overlap and at connecting elements such as gable corners or ridge caps, the nails are driven in on every wave peak.
Self-tapping nails are inserted vertically through the corrugation into the bottom sheathing. IMPORTANT! The nail is inserted only until its plastic head presses the board, but does not deform it!
The transverse overlap usually consists of only 1 wave. In the places of connection with the gable and with a roof slope of less than 10° or in areas with extremely high atmospheric loads, a two-wave overlap is recommended.
In the longitudinal direction, the boards must overlap by at least 140 mm. The longitudinal overlap must be made in the area of the bottom sheathing. To ensure a stable surface, the nails are driven in again at each wave peak.
In the ridge area, the slabs end approximately 50 mm below the upper ridge line and are covered by the ridge cap over a sufficiently wide area.
The gaps that form between the lower part of the waves and the supporting surfaces (both with the eaves area and in the ridge area) ensure maximum cross ventilation of the roof surface.
If these "forced ventilations" are blocked with foam profiles, then ventilation elements must be placed in the roof surface. When placing these elements, transverse and longitudinal overlap must also be ensured.
