Our company also produces various custom products, the main material of which is the CETRIS cement-bonded board. Its basic technical, price and usage options are listed on www.cetris.cz.
Examples of our products
Lost formwork for the production of sewerage shafts
It is a CETRIS cement-bonded board, which is used as a lost formwork of shaft bottom from an inner diameter of 1000 mm up to 1600 mm. The board is adapted for different mounting into the mould - the modification is made according to customers - different materials - see photo.
Ribbed insulating boards
It is used for the construction of a concrete wreath on buildings, where the CETRIS exterior colour plate also serves as a viewing surface. The insulation board with the CETRIS BASIC base plate is most often used to insulate the foundations of the house, in which case CETRIS serves as a protection layer against earth. The most commonly extruded polystyrene or foam polystyrene is used as insulation.
The thickness of the cetris plate and its surface treatment, insulation thickness and type of insulation as well as the dimensions of the individual modules are produced according to the customer's wishes.
The attached drawings show the basic technical specifications of the ring plates. Technical, material, and insulating possibilities of products as well as price specification will be sent by our employees according to customer requirements. From our product range we can offer ring plates with sharp edges, their technical specification is below.
If the customer requires a different solution, we offer the possibility of supplying these ring insulation boards with a 2 / 2mm phase. Below is a drawing of both options and assembly. The overlap Cetris / insulation serves for proper bonding so that no thermal bridges are formed. Bonding is effected very efficiently by low-expansion PUR foam, as well as bonding to the concrete base. If the board is of a larger size and is not loaded with soil on the outside, it is necessary to ensure its mechanical anchoring according to the rules for anchoring of Cetris boards (see technical specification or consultancy of the manufacturer).
The optimum modules of the insulation boards, given the price, will be sent to our staff by telephone request.
Construction hatch square
The hatch consists of a cetris plate th. 20 or 22 mm in the natural design CETRIS BASIC, with one or two lifting brackets, neoprene insulation in the frame in which it is laid, and thermal insulation most often made of foamed polystyrene (see photo). The cover is used for the warm closing of the technical floor or the premises with technical distribution in the buildings. The top of the hatches overlaps with the flooring in the room or adjusts as required by the building. The size of the hatches, the thickness of the thermal insulation or the number of fastenings is governed by customer requirements. The price for the product is determined by the complexity and quantity required in the order.
There are three basic types of hatches in our product range. The dimensions of the hatches are based on the customer's requirements - depending on the load-bearing capacity as well as on the required insulation properties. Hatches are placed in metal frame – see picture where the sound insulation is provided by neoprene insulating tape. The exact specification of the basic hatch is in the enclosed technical drawings. Required technical, dimensional, material and price specifications will be specified according to customer requirements.
Basic square hatch:
Square hatches lockable - two locks
These are the building hatches, whose technical specification is in the attached drawings. For use in buildings, the hatches can be equipped with locks to secure technical entrances or cover openings. Depending on requirements, the hatch can be equipped with a pair of locks with separate keys. Locking is performed to the metal frame in which the hatch is inserted. The frame is then anchored to the floor or wall construction. The dimensions and technical specifications of the hatches are always based on customer requirements.
Square hatches lockable - central lock
These are the building hatches, whose technical specification is in the attached drawings. For use in buildings, the hatches can be supplemented with a central lock with a wheelbase to secure technical entrances or cover the openings. Locking is performed to the metal frame in which the hatch is inserted. The frame is anchored to the floor or wall construction. The neoprene strap ensures sound insulation. Another possible option is to screw the hatches to the metal frame. The dimensions and technical specifications of the hatches are always based on customer requirements.
Construction hatch round
For special use, we can also supply the construction of a hatch with a circular profile. Unified round frames can be used for this application, to which an insulated hatch made of CETRIS cement-bonded particleboard can be supplied, most often with a thickness of 20 - 22 mm, provided with EPS insulation according to customer requirements and a neoprene seal to reduce soundproofing and properly separate spaces. Each hatch is equipped with two rings for handling. The hatch can be supplemented with a lock for locking the given opening - the technical design depends on the given place. These building hatches are manufactured according to customer requirements in terms of size and composition.
It is a CETRIS board with holes, which serves for technical and fire separation of individual rooms or measuring cabinets, in high-rise buildings from the area of technological distribution - water, telephone, gas, el. energy, etc. Only the individual inlets to the housing units or the measuring cabinets to the individual meters are exposed. The underside of the installation board is equipped with a self-extinguishing polystyrene for the thermal separation of the technological distribution areas from the living areas. The assembly and the size of the holes, as well as the thickness or the nature of the thermal insulation, are at the customer's request.
