LAWAPAN-ACOUSTICS BY MEANS OF HOLES OR SLOTS LAWAPAN, EASY TO REMOVE Lowered ceilings offer the space for utilities such as ventilation channels, electricity conduction and computer cabling. The ceiling also serves to protect these installations and the building skeleton in the event of a fire. These utilities occasionally require maintenance and repairs. This means that access through the ceiling must be possible. LAWAPAN wood veneer panels create a lowered ceiling system which enriches the interior of the building. The core of the ceiling panels consists of MDF, chipboard or multiplex. LAWAPAN panels can be assembled using visible, concealed or half concealed hanging systems. Thanks to the particular attention to both the sizing of the panels as well as the even finish of the edges, individual panels can be easily removed at any place without causing damage.

LAWAPAN, EASY TO REMOVE LAWAPAN SYSTEM the ideal solution These semi-concealed and fully removable ceiling panels provide complete access to the ceiling space. The use of springs enables both the placement as well as the removal of panels from below. The ideal solution: because the total ceiling space can be fully utilized for facilities. The unique edge working hides in part the carrying construction and ensures a visible join of 8 mm between each panel. Due to this a contrasting effect can be created between the panels and the T-profiles. The System panel type is assembled using a carrying construction consisting of T-24 mm profiles. Various panel sizes can be combined in one ceiling system. The spring system also enables the panels to be used outdoors, where grill panels can be combined in the total ceiling system to reduce wind pressure. LAWAPAN SELECT carrying construction completely invisible The special edge finish of the panel type Select ensures that the lowered ceiling requires no visible weight bearing construction. Every ceiling panel is invisibly joined and is removed by pushing the panel upwards and passing it to below. In order to achieve this, a minimum hanging distance of only 150mm is necessary. The panels have a slanted edge finish, bevelling, which creates a flat surface when mounted with a Z- or T- profile.
LAWAPAN STANDARD AND TREND A lowered ceiling with access to facilities such as pipes and electricity circuitry is not always necessary. In schools, open office spaces and existing buildings, the attachment of panels onto the bare ceiling provides extra ceiling height. Perforation or groove patterns on the panels are used to improve acoustics. Lawapan Standard and Trend panels can be mounted directly onto a wooden infrastructure using screw clips. A hanging distance of about 50 mm is sufficient for this purpose. Assembly using a turnclip onto a metal omega profile, or T-24 mm profiles, is also possible. To improve the fire resistant and sound absorption qualities of this ceiling type, the space between the ceiling panels and the building ceiling is insulated with stone wool. Veneered panels mounted onto a wall create a space with a warm ambience where the wood structure is clearly visible. The core of the wall panels consists of MDF, chipboard or multiplex. Thanks to exact sizing and with the help of metal profiles, hanging brackets and screwclips, the panels can be assembled quickly and may be removed as desired. Sound absorption is accomplished through the use of perforation or groove patterns on each panel to achieve an optimal acoustic effect.
LAWAPAN STANDARD Veneered panels selected by the Architect can be fitted with a melamine or veneer edge band. It is also possible to finish the panel with a solid edge strip or a plastic PVC edge band. After assembly a distance of 1, 5, 10 or 20 mm is visible between the panels. Screwclips and connecting strips in the same wood type, or contrasting colour, are used for assembly. LAWAPAN TREND These veneered panels are joined together using a MDF connecting strip and screw clip. After assembly only the bevelled edge is visible. In this way, it is possible to bookmatch the wooden structure of each panel and ensure continuation. It is also possible to mis-match the panels to provide a natural, variable wood art effect. Also available in a spray painted RAL or NCS colour or with plastic melamine decor.
Wood is used efficiently in the production of veneer. Due to modern production methods around 800-1000 m 2 of veneer can be produced from 1 m 3 of wood. Lambri works only with veneer which originates from controlled reforestation areas. Veneer sheets with a width of 10-25cm are book-matched and glued to form panels. Upon request it is also possible to produce slip-matched or mismatched sheets.
Fire Safety Data Lambri panels are fabricated from Topan FR MDF with fire retardant core Euro Class B-s2-d0 and finished in an intumescent varnish or lacquer to achieve Euro Class B-s1-d0 if required. The Soundtex backing fleece is certified Euro Class B-s1-d0 Weight Nominal panel weight of 10kg/m 2 based on 17mm thick MDF. Maintenance Clean panels with a non- abrasive cleaner. Manufacture Standard panels are available in all sizes up to 2400mm x1200mm in 12mm (lay in tiles only), 16mm & 17mm MDF, however, for ceiling execution any panel over 1200mmx600mm will not be accommodated by standard fixing method. For economy 1200mm x 600mm x16mm panel type is recommended. Panels manufactured with 4mm groove in perimeter to accommodate mounting clip & cover slip. All veneered/melamine panels have balancing veneer to rear face of panel. Edge banding is normally melamine or real wood veneer. Soundtex black fleece is adhered to the rear to prevent fibre migration Installation For wall execution they are retained to a timber sub frame by means of secret clips nominally at 600mm cc. For ceiling execution they can be fitted to a timber sub-frame or to heavy duty T grids both by means of secret clips at 600mm cc. Lawapan panels have a groove around the perimeter to take the mounting clip and 3mm ply masking strip. The expressed joint can be 1mm, 5mm, 10mm or 20mm Acoustic Performance Acoustic data in this brochure is based on a 50mm thick 45kg/m_ Rockwool absorber fitted to the rear of the panel.
