Burning behaviour parameters of panels with PI/PIR+ core are given in accordance with PN-EN 14509:2013 standard.

Balance of benefits

Sandwich panels with coated metal lining have been used in building industry for over 40 years. Some of the benefits of using our sandwich panels are:

Thermal insulation.

Thermal conductivity of panels with polyisocyanurate foam core is 0.022 W/mK.

Durability.

Protection against weather conditions, maintaining properties and appearance for many years. When coating is properly selected for local conditions, several years’ durability of panels may be reached without any problem.

Waterproofness.

Water, snow and damp will not get through. Perfectly finished joints ensure complete waterproofness for many years, if installation standards are followed.

Sound absorption.

Properly selected core material can give very good 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. Proper type of core can ensure reaching fire resistance class up to A (mineral wool). This enables protection of escape routes and separation of fire compartments from each other.

Easy and quick installation, low construction costs.

10mm thick PUR/PIR foam panel has the same heat-transfer coefficient U as a 390 cm thick aerated concrete wall, or a 290 cm thick brick wall.

Resistance.

Roof panels can withstand the load of snow and wind depending on their thickness and climatic zone, with supports placed every 3 m. Wall panels in most cases can be used with supports span of up to 6 m. This results in real savings in terms of the supporting structure and also in the costs of the entire building.

Benefits for the natural environment.

Entire power input in the production of the material used for thermal insulation of the building pays for itself after two or three years from installation, on average. 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.

Stainless steel

PUR/PIR/PIR+ panels are also manufactured with stainless steel cladding.

Profile types

Thanks to the variety of profile types of JUNDAPANEL sandwich panels lining and a wide selection of paint coats in various colors, our products can give a unique character to any building.

General characteristics

Core

The core is made of hard incombustible lamella mineral wool and PUR/PIR edged banding, which can ensure water-repellent effect. Mineral wool products do not absorb water and form a spatial and stable base of insulation, PUR/PIR foams are characterised by very good physical and chemical parameters, high resistance to moisture, high chemical resistance and resistance to fungi and mildew. The combination of the two makes the sandwich panel both visually appealing and effective in insulating, fireproofing, and waterproofing.

Benefits

The core of JUNDAPANEL PUR+ sandwich panels is mineral wool (stone wool)and PUR/PIR. MWF has good insulating and thermal properties, which is reflected by thermal conductivity rating:

λ =0.022- 0.040 W/m*K

PUR+ panels also have very good noise insulation properties which is characterized by specific acoustic resistance coefficient:

R_w= 25-27 dB

and acoustic absorption coefficient:

α_w = 0.15

Including the burning behaviour of sandwich panels with mineral wool core the product can be classified as

B

Flash resistant

Panels with PUR+MWF/rock wool core show very good results of fire resistance tests. Depending on the core thickness their fire resistance class is

EI 15

Proper joint profile guarantees perfect leakproofness, preventing air infiltration and ensuring steam and blowing rain resistance.

PUR+MWF/rock wool panels manufacturing programme includes single type of wall panel and single type of roof panel.

Wall panels are available in three types:

• JundaWall

Standard wall panel. Thickness range: 40 to 150 mm. Suitable for walls, to be installed vertically or horizontally. Fastening to the structure with screws through the panels.

Roof panels are available in two types:

• JundaRoof

Suitable for pitched roof with small and medium pitch angle. These panels have trapezoidal outer surface. Thickness range: 60 to 150mm. On request JundaRoof panels may be produced with a lap joint which enables longitudinal assembly. The lap joint may be left-sided or right-sided.

JundaWall

Unique performance in fireproof, soundproof and thermal insulation. PU (PIR) closing ensures water-repellent effect; Joint of the panel keeps good air-tightness.Hidden screw joint, keep high flatness of the panel surface.

Guidelines

Recommended means of transport and its technical conditions:

Lorries with an open load-carrying body or an open trailer enabling loading long panels (up to 13.60 running metres ) from both sides of a car constitute the basic means of transport for sandwich panels.

The following technical conditions are recommended for vehicles for transporting sandwich panels:

• load-carrying body with canvas cover (“CURTAIN” type)

• load-carrying body longer than transported panels (a package of panels should be placed on the platform in its entire length)

• transport belts holding the load should be placed on a package of panels on each support (belt tension can deform panels)

Unloading & transport:

Check if the package is complete and specify any possible inconsistencies immediately upon delivery.

For packages up to 6m it is permissible to use forklift trucks of adjustable fork width, min. fork span 2m at min. width 150mm. While unloading the products with forklift trucks, pay particular attention to fork length and thickness, so as not to damage the second row of products in the vehicle and the upper cladding of lower packages.

Manual unloading is permissible for products of up to 6 m length, when taken down one byone, and with special caution. Dragging the products on the floor and on one another is forbidden.

Packages of products longer than 6m must be lifted on transport belts by means of a spreader beam. Recommended belt span for packages from 6 m to 12 m is 2-4 m at their min. width 200 mm. For packages of over 12 m length , transport belt span is 3,5-4,5 m, at their min. width 200 mm. It is recommended that the belts are placed on distance pads of min. 300 mm width and min. 25 mm thickness, on the upper and lower package panel.

Using suspensions from steel lines or chains is forbidden. It is inadmissible to lift the packages on clamping or crossing belts, or using any other methods that might damage the product.

Panel storage:

Packages should be stored on flat ground with a slight inclination, to make sure all the pads lie on the surface precisely and rainwater is drained from the areas in between the packages. It is allowed to store two packages placed one on another at the most.

Storing in closed, airy spaces is recommended, at normal temperatures, away from acids, lye, and other corrosive substances. When stored in the open air, the packages must be secured against rain and dirt by means of tarpaulins that give access to air flow. Remove the protective film from the product no later than after 2 months of the date of production.

Small repairs and maintenance:

All damage to coating caused during transport or assembly should be covered with touch up paint. Maintenance of sandwich panels consists in performing regular inspections and securing potential damages. During inspection close attention should be paid to uncovered edges and joints.
