STRESS-FREE FLOORING ASSEMBLY FOR CONTINUOUS SCREEDS AND HYDRONIC RADIANT HEAT ACCOMMODATION

Schluter

-BEKOTEC is a lightweight

modular screed system that is used

to create continuous screed surfaces

without control joints or reinforcement

and is designed to accommodate

hydronic radiant heating tubes. Since

it is a floating system, the assembly can

be customized to meet a range of heat

and sound requirements.

Application and Function

9.1 Schluter

-BEKOTEC and 9.2

Schluter

-BEKOTEC-F are modular screed

systems that produce permanent floor

ing assemblies that are free from internal

stresses. The bases for these systems are

the Schluter

-BEKOTEC-EN/US/P and

Schluter

-BEKOTEC-EN23F studded

polystyrene screed panels that are

placed directly over any load-bearing

substrate and optional common sound

and/or heat-insulating layers. The studs

effectively divide the screed into smaller,

4-1/4" (108 mm) square modules, thereby

confining shrinkage and curing stresses to

control deformations such as curling and

continuous cracks that can be common in a

traditional screed. These modular screed

systems allow the installation of continuous

screed surfaces without any control joints

or wire reinforcement. The elimination of

control joints allows surface movement joints

to be placed to match the joint layout in the

tile covering.

The cross-section of the assembly reveals

a minimum screed thickness of 1-1/4"

(32 mm) between the studs and 5/16" (8 mm)

above the studs. This results in significant

material and weight savings over traditional

screeds. For example, a 1-1/4" (32 mm)-thick

traditional mortar bed weighs approxi-

mately 15-lb/ft

(0.72 kPa), while a BEKOTEC

mortar screed weighs approximately 12 to

12.5-lb ft

(0.57 - 0.60 kPa), representing a

15- 20% decrease. Material and weight

savings compared to a 2" (51 mm)-thick

mortar bed amount to approximately 50%.

The studs form a grid pattern, with a

distance of 3" (76 mm) between studs

to accept hydronic heating tubes 3/8"

(10 mm) to 5/8" (16 mm) O.D. if a heating

screed is to be installed. Since the screed

mass to be heated is relatively small, the

floor heating can be well regulated and

operated at a low temperature range.

The modular screed system reduces

impact sound transmission. Since it is a

floating screed system, it is also possible to

incorporate a variety of sound attenuation

materials below the panel, allowing for even

greater impact sound reduction.

Ceramic and stone tile is installed

over the BEKOTEC and BEKOTEC-F

modular screeds using the Schluter

-DITRA

uncoupling membrane. Please refer to the

Schluter

-DITRA Installation Handbook

(detail D-C-TS for Portland cement-based

screeds and detail D-G-TS for gypsum-

based screeds). Surface coverings not

sensitive to cracking, such as parquet or

carpet, can be placed directly over the

screed as soon as the residual moisture has

reached an appropriate level.

MODULAR SCREED SYSTEMS

Material Properties and

Areas of Application

BEKOTEC is manufactured using closed-

cell expanded polystyrene and is suit-

able for use with conventional mortar and

poured screeds. BEKOTEC requires no

special disposal and can be recycled. No

CFCs or HCFCs are present in either the

material or the manufacturing process.

The expanded polystyrene foam used to

manufacture BEKOTEC is treated with

a flame-retarding agent. The foam is

self-extinguishing and achieves an HF-1

rating according to UL 94. Expanded

polystyrene should not be exposed to

hydrocarbons, esters, amines, and

aldehydes. Common examples include

solvent-based adhesives and diluting

agents, oil-based paints and stains, and

petroleum fuels such as gasoline and

kerosene. All will deteriorate foam.

Exposure to ultraviolet rays (sunlight) for

long periods of time will result in partial

degradation (dusting) at the surface.

BEKOTEC-F is manufactured using high-

impact polystyrene foil and is suitable for

use with conventional mortar and poured

screeds.

MO D U L AR S C R EED SYSTE M S Installation 1. BEKOTEC or BEKOTEC-F is installed over an even and sufficiently load-bearing substrate. If additional insulation is required, place a layer of expanded or extruded polystyrene foam panels over the substrate and cover with a sheet of polyethylene. 2. At the perimeter, where the covering meets walls or restraining surfaces, place the 5/16" (8 mm)-thick edge strip, Schluter®-BEKOTEC-BRS or -BRSK.

Stud diameter: 2-19/32" (66 mm) Grid spacing for heating tubes: 3" (76 mm) Diameter of heating tubes to be used: 3/8" – 5/8" (10 – 16 mm) O.D. The studs feature an all-around cutback design, which ensures that the heating tubes are held securely without clamps in straight runs. Clamps may be necessary where the tubes are turned into a relatively tight radius. 2.
