Sandwich Panel
Panel Tech’s specialized in production, sales and export of Polyurethane (PU) & Polyisocyanurate (PIR) Insulated Sandwich Panel & Rockwool. Sandwich Panels are produced in a continue line with 3 types of insulation materials including such as, Polyurethane (PUR), Polyisocyanurate (PIR) & Rockwool insulation thicknesses. As external and internal surfaces of sandwich panel painted galvanized, galvalume, Alu-zinc, stainless steel, Painted or natural aluminum materials can be used.
Some of the benefits of using Panel Tech’s sandwich panels are:
- Excellent thermal insulation. Thermal conductivity of panels with polyisocyanurate foam core is λ = 0,022 W/m*K.
- Excellent protection against weather conditions, maintaining properties and appearance for many years. When coating is properly selected according to local conditions, several years’ durability of panels can be reached without any problem.
- Complete seal against precipitations, snow and dampness. Perfectly finished joints ensure complete waterproofness for many years, if installation standards are followed.
- Sound absorption. Properly selected core material can give perfect noise insulation parameters. They are particularly important if insulation of outside noise, reduction of industrial noise propagation to the outside of the building or noise reduction within the building is required.
- Fire resistance properties according to the needs. Using proper type of core can ensure the fire resistance. This enables protection of escape routes and separation of fire compartments from each other.
- Easy and quick installation, low construction costs. As a result, lower operating costs over the years. A 50mm thick PU/PIR foam panel has the same heat-transfer coefficient U as a 75 cm thick aerated concrete wall, 60 cm thick struc¬tural clay tile wall or a 190 cm thick brick wall.
- Good strength parameters. Roof panels can withstand the load of snow and wind depending on their thickness and climatic zone, with supports’ span of more than 3 m. In most cases, wall panels can be used with supports’ span of up to 6 m. This results in real savings in terms of the supporting structure, and thus overall costs of the entire building.
- We have managed to combine all the above benefits to the user with benefits to the natural environment. Total po-wer input in the production of the material used for thermal insulation of the building, on average, pays for itself after two or three years from installation. Materials used in production are recyclable. Steel can be easily reused. Waste core materials can also be recycled, while production of the panels itself is not harmful to the environment.

Z-section Dimensions and Properties
The section reference of a Z-section 232mm deep and 1.8mm thick would be 232 Z 18. The first 3 digits of the section reference indicate the depth of the section in millimeters (i.e. 232 equals 232mm deep). The fourth digit is a letter that signifies the profile type (ie Z for Z-section). The last two digits indicate the material thickness (i.e. 18 =1.8mm).
Translucent Sheet

Flashings
Panel Tech can fold a wide range of standard or custom flashings to suit your requirements. Flashings are available in pre-painted steel, zinc/al, aluminum, mill finished galvanized. Choose from a wide range of available thicknesses from 0.3mm to 2.0mm depending on your state.
Box Gutters
A square or rectangular gutter that is used within the boundaries of the roof. It may be formed between a roof surface and a parapet wall or between two roof surfaces. Available with enfold, out fold, splash back and squash fold edges. This gutter is usually supported on a box gutter board to improve strength and stiffness and to minimize damage caused by roof traffic.
Industrial Eave Gutters
A purpose made external gutter which is located at the edge of an industrial roof. It is usually supported by heavy gauge brackets that have been designed specifically to suit the industrial eaves gutter shape. When made in larger sizes special attention should be given to minimizing oil canning of flat surfaces by adding extra ribs into the design.
Valley Gutters
A shallow gutter formed to suit the angle between two internal slopes of a roof. Its design will usually include a return at each edge to minimize the possibility of water spillage into the roof space. Depending on the size and application additional internal stiffening ribs may be included.
Corner Flashings
A folded piece of steel used for waterproofing wall sheeting where two walls meet to form an external corner. Where used with steel sheet walling it should lap at least one rib and a recommended two ribs for maximum water proofing.
Apron Flashings
A folded piece of steel used to prevent water from penetrating the space where a vertical surface intersects a roof. Where used with steel sheet roofing it should lap at least one rib and a recommended two ribs for maximum water proofing. Wider apron flashings are advised when the base of the flashing faces into the prevailing wind.
Ridge Flashings
A steel covering over the ridge to provide a continuous cover and effective weather seal between two slopes. The size of the edge break should conform with the rib height of the steel roofing to which the ridge is attached. Good roofing practice is to notch this edge break to neatly fit around each rib of the roof sheet.
Parapet Capping
A covering used to waterproof and cap the ends of vertical sheets or masonry walls. A stiffening edge or break is often applied to the legs of the parapet cap for a more appealing appearance, and to minimize oil canning of the steel. Ensure that these recommendations are considered when measuring the flashing. It is also important to ensure that water does not pool on top of the cap, to prevent water seeping into the building.
Barge Capping
A folded sheet used to waterproof the junction between a fascia or barge board and roof sheeting. The size of the edge break should conform with the rib height of the steel roofing to which the ridge is attached.
Roller Shutter Doors
The shutter curtain is constructed from cold rolled galvanized concave steel laths, (75mm), of suitable gauge to suit the application. Each lath is retained pressed steel iron end lock fixed with galvanized steel rivets. Cast Iron wind locks are fitted to help prevent the curtain being orced out of the guide during high winds, as and when required.
