Metal frame 

● Apply Acoustical Sealant (two strings) to backside 

of runners for connection to ceiling and 

fl oor. Fasten runners with appropriate fasteners 

(e.g. Knauf Nailable Plug). Spacing of fasteners 

max. 1 m. Aligne UW Runner exactly 

horizontal at floor! 

● Apply Acoustical Sealant (two strings) to backside 

of CW Stud and fasten it to the fl anking 

wall where installation starts. Spacing of fasteners 

max. 1 m, min. 3 fasteners. 

Knauf Torro in the cavity of partition 

● To fi x the fi rst Knauf Torro boards apply Acoustical 

Sealant into CW Stud, slide-in board 

(width 600 mm) vertically and press-on tightly 

against CW Stud (pound with rubber mallet if 

necessary). 

Subsequently shorten second layer by 300 

mm and glue it to the already installed board 

with 2 strings of Acoustical Sealant using 

screw clamps. 

● Apply following Knauf Torro displaced to each 

other by approx. 300 mm, glue both layers to 

each other with Acoustical Sealant and presson 

tightly to CW Studs. 

● For metal frame with CW 100: To aligne Knauf 

Torro elements correctly in the cavity of the 

partition, glue gypsum board pieces (approx. 

40x40x12.5 mm) at a spacing of approx. 1 m 

into CW Stud fl anges with Acoustical Sealant 

and press Knauf Torro boards against the 

same fl ange. To make installation easier apply 

pieces of roof laths (or two gypsum board 

pieces) between other fl ange and Knauf Torro 

board (remove before applying the cladding). 

● Cut top Knauf Torro according to the necessary 

height and install it. 

● Starting the second section install Knauf Torro 

horizontally (width 624 mm) to reach the modular 

spacing of 625 mm while still taking care 

of the joint displacement (approx. 300 mm). 

Carry on until all sections are lined with 2 x 

28 mm Knauf Torro. Install CW Studs (apply 

one string of Acoustical Sealant in the middle 

of the web of the stud) with web turned to the 

boards and crimp with Stamp Pliers. 

Caution: turn last stud, that means install with 

opening towards the boards! 

● Fixation of the last section is carried out using 

metal sheet angles with Knauf L Angle Profi 

le 13/30/08. Put fi rst angle profi le against 

UW Runners (apply Acoustical Sealant before) 

and crimp. Subsequently fasten to fl anking 

wall at the shorter, perforated angle arm 

with a spacing of approx. 500 mm. Glue gypsum 

board piece (approx. 40x40x12,5 mm) 

between angle profi le and Knauf Torro with 

a spacing of approx. 1 m using Acoustical 

Sealant. Install Knauf Torro boards, press-on 

against the respective angle arm and fasten 

second angle profi le on the opposite side of 

the partition again aligned with the fl ange of 

the UW Runners.

X-Ray Shield Partitions / Furrings 

Requirements, Technical Data 

K131 / K151 

Requirements 

Formerly for radiation protective purposes used 

heavy concrete constructions in hospitals and 

medical practices can nowadays simply, effi - 

cient and fl exible be replaced by Knauf X-Ray 

Shielding Systems with lead sheet laminated 

Knauf Boards. Knauf X-Ray Shielding Systems 

can be used in the sector of X-Ray diagnostics 

and X-Ray therapy of lower power. 

X-Ray radiation protection is provided with 

shielding, room enclosing constructions with a 

specifi c lead equivalent value of the used materials. 

The lead equivalent value as reference parameter 

shows the relation between the shielding 

effect of the material compared to the equivalent 

lead thickness. Therefore the required lead 

equivalent value corresponds to the thickness of 

the lead sheet, e.g. lead equivalent value 2 = 2 

mm lead sheet. 

The base of all building related X-Ray radiation 

protective actions is the Radiation Protection 

Programme, that has to be created by the 

manufacturer of the X-Ray devices. Information 

about the lead equivalent values of different 

building materials is provided in DIN 6812, 

table 16. While installing X-Ray shielding constructions 

care has to be taken that the shielding 

is completely tight.

taken into account for the load class determination. 

The determined weigth from thew 1st step has to be 

increased by the value of the extra load in the 

direction of the y axis (upwards). 

3. Determination of the load class 

With the resulting total weight per unit area of

Jointing / Surface treatment 

Filling material 

● Fill in joints with Knauf Unifl ott or TRIAS without 

using tape. If using tape, hand fi ll in with 

Knauf Fugenfüller Leicht or with Ames machine 

and Knauf Jointfi ller-Super. 

● The color of Knauf TRIAS matches the paper 

color of gypsum boards. Knauf TRIAS has a 

reduced suction behavior after drying. Surfaces 

fi lled with Knauf TRIAS are of low contrast 

and especially advantageous for paint coats 

and fl eece wallpaper. 

● Use Knauf Finish-Pastös for the fi nal fi lling 

coat as fi ne skimming before sanding the 

joints. 

Application 

● For double layer cladding, fi ll joints of fi rst layer, 

smooth joints of second layer. 

● Cover all visible screw heads as well. 

● Recommendation: Fill in and tape cut edges 

of visible layers no matter which filling material 

is used. 

● Use Knauf Spezialgrund to prime the entire 

surface of fi lled Knauf boards to control suction 

and for optical harmonization of the surface. 

Knauf Spezialgrund is a system component 

for the creation of surfaces with higher 

quality requirements according to code of 

practice no. 2 „Verspachtelung von Gipsplatten 

- Oberfl ächengüten“ of the IGG. 

Application temperature/ Climate 

● Filling and covering of joints should only take 

place after the boards have been allowed to 

rest in the given humidity and temperature 

zones, and no more longitudinal changes can 

be expected, i.e. expansion or contraction. 

● Joints should be filled at a minimum temperature 

of +10°C (50°F). 

● In case of mastic asphalt screed or flooring 

screed, fill in joints after screed has been applied. 

Surface Treatment 

Before applying paints or coats the fi lled surface 

should be dust-free. Use a primer on Knauf 

Boards before coating or painting them. Ensure 

that the primer and the coat or paint are compatible. 

The following coats can be used to cover Knauf 

Boards: 

● Coats: Washable and abrasion-proof emulsion 

paint, multicolored (rainbow) emulsion, 

oil paint, matte-fi nish lacquer, alkyd resin 

paint, polymer resin paint, PUR lacquer, or epoxybased 

lacquer, according to intended use 

or as required. 

● Plasters: Knauf structured plasters, e.g. resin 

plasters, thin plasters, entire surface smoothing 

like e.g. Knauf Board-Finish, mineral plasters 

in connection with paper taped jointing. 

After the application of resin / cellulose plasters 

quick drying must be assured through adequate 

airing. 

● Ceramic tiles (on partitions and furrings): For 

tiling at least double layer cladding is recommended. 

If a single layer cladding is unavoidable 

spacing of studs must be reduced to 42 

cm. 

● Wallpapers: paper-, textile and synthetic wallpapers. 

Use only adhesives made of cellulose 

according to „code of practice no. 16 

“Technische Richtlinien für Tapezier- und 

Klebearbeiten“, Frankfurt/Main 2002, released 

by Bundesausschuss Farbe und Sachwertschutz. 

After wallpapering of paper and fi - 

ber glass wallpapers quick drying must be assured 

through adequate airing. 

● Alkaline coats such as lime, water glass colors 

and silicate-based paints are unsuitable 

for gypsum board surfaces. 

● Silicate-based emulsion paints may be used 

after referring to the manufacturer’s recommendations 

and following the stipulated 

guidelines closely. 

Gypsum plasterboard surfaces that have constantly 

been exposed to light without any protection 

can develop yellowing agents that show 

up despite a coat of paint. Therefore a trial coat 

is recommended that will extend across several 

boards including all joints. Yellowing can, however, 

be successfully avoided only by using a 

special shielding primer.
