Silicate cam boards. From theory to practice.

Curtain room dividers today often erect not from conventional brick or thick blocks, and of the special, designed specifically for the purposes of these materials - gypsum partition boards. They are available in two varieties - gypsum (GWP), which have already been discussed in One of the articles on our website, and silicate, which will be discussed today. Acquainted with the characteristics of the material and laying technology and expertise for its application, participants share FORUMHOUSE.

Characteristics

Silicate partition plate as brick, produced from a mixture of sand, water and quicklime pressing method followed by treatment with steam under high pressure (autoclaved). Material characterized by flat, smooth surface and good geometry, and pazogrebnevyh mounting system enhances bond strength. Since the raw material base and method of manufacturing silicate plates heavier and denser gypsum, on the one hand gives an increased thermal conductivity, while on the other - greater strength. Dimensions silicate pazogrebnya vary by manufacturer, but they are somewhat less due to weight than that of gypsum. Produced solid and hollow (porous) plate at the second higher sound insulation performance and less weight. All silicate partition plate has a low ability to absorb moisture, they can be used in any environment.

Choosing panels for walls, ceilings take into account the type and purpose of the room. Wooden logs and a children's room - lightweight pustotki; concrete slab, and the walls will hang heavy furniture or appliances - massive full-bodied. In some situations, when communication can not be held in a single-layer wall, or need increased protection heat and noise - barrier do double paving inzhenerku inside and an insulating material, for example, mineral cotton.

Specifications plates

• Density - from 1225 to 1870 kg / mᶟ (depending on the voidage).
• Strength - 150 M.
• Coefficient of thermal conductivity - about 0.045 W / (m * C).
• airborne noise insulation index - from 48 to 52 dB.
• Dimensions - 498x70x248 mm, 495x88x248 mm, 500x250x70 mm, there are 115 mm thick slabs, but their manufacturers positioned as mezhkvartirnye.

Lime brick used often used for the construction of mezhkvartirnyh partitions thanks to the ability to extinguish a sound efficient ceramics. That silicate boards today are choosing not only for strength, but also to improve the sound insulation.

Xameleon (User FORUMHOUSE):

I plan to use silicate cam boards in the summer, as the interior walls of the house. It attracts level of sound insulation and strength compared to other materials. About silicate bricks write that the best sound insulation means for the plate interior partitions - it.

mount technology

Although the system of fastening the plates together with adhesive and provides a sufficiently reliable solid compound septum length as that of gypsum, should not exceed 6 meters, and a height of 3.6 meters. The contours of the partitions are advised to draw or beat off the walls and ceiling. Since pazogrebnevyh Connect requires the finest seam plates stack is not an ordinary DSP, and a special glue - it has a higher permeability, and it provides a secure fit. Available in special formulations for plates, usually at the same company as the plate, but can also be used for gas silicate glue. One of the participants in the portal using tile adhesive.

aldegid (User FORUMHOUSE):

Geometry at the plate normal, put on a normal tile adhesive, tried to glue gazosilikata, not very much - dries faster.

Unlike the brick and other masonry species at a laying plate with slotted compound will neutralize not error base seam thickness as it minimum (about 2 mm), and it should be as originally even. If necessary, a partition make additional layer covering, deducing the horizon is level. First row better laid on a solution pre-primed substrate.

aldegid:

First row put in solution rather on peskobeton M 300. First I tried on a thick layer of glue, but it is too plastic and squeezed under the weight of the blocks.

If you talk about hardwood floors, in the place of application partitions to be supporting beam that is taken into account at the design stage.

Masonry itself is no different from the standard - required bandaging, for which the first plate of the second row is sawed. Despite the good geometry and groove joints in the masonry is necessary to monitor the deviations through the building level or plumb, since the silicate boards horizontal grooves not.

If doorways not more than 80 cm, and the top one row of plates, optionally amplification. If larger, you must use the jumper (angles, rebars, channels, wooden beams). To improve the sound insulation between the wall and the wall of paving special damping tape or its substitute (cork, foamed PET, bitumizirovanny felt). A compound with the wall can be either elastic - via a damper plate perforated brackets in the groove each row and self-tapping screws or anchors to the wall, and hard - to glue, staples or punched rebar. For hedging and the first row can be locked.

wh1t3cAt1k:

I laid approximately 55 squares walls of porous silicate plates (70 mm). Binding to the floor: the first series of stacked on adhesive solution, every two blocks tied to RC overlap armature 8 mm. Binding to the walls: adhesive solution, plus every two blocks - similar reinforcement.

As for the reference to the ceiling, it is not necessary for short walls - enough to leave a groove in a couple of centimeters and zapenit or cover up with a solution (after laying communications). But the long septum best efforts, scoring reinforcing pins or by screwing brackets (corner) on the anchor, and after zapenit. Which option to choose depends on the parameters of the house.

wh1t3cAt1k:

Binding to the ceiling: zapenil, every half meter tied reinforced metal area with dowels. I still do not know why I did that, the ceiling - RC plate M 400, the house seven years standing, bending it zero. If done now, just I am filled with a solution.

Silicate partition plates outperform gypsum not only in strength but also in cost - available raw materials and major manufacturers to provide the output of a very reasonable price. The main advantage of the gypsum partition boards over other types of walls - smooth surface that does not require plaster enough layer finishing putty, which is confirmed by our craftsmen.

wh1t3cAt1k:

The geometry of the plates have a wonderful, plaster is not exactly right.

I agree with this and aldegid.

aldegid:

I think to do without plaster - plaster only.

In the process, any difficulties with the silicate does not occur well plates are cut with a diamond disc grinder, you can not only customize the rubber mallet, but also ordinary iron hammer. but aldegid advises not to engage strongly in the room, as a lot of dust is formed, may have cost wet disc or unit, as in the case plastushkoy.

Silicate or gypsum, cam boards can speed up the construction of barriers and due to the relatively low weight can be used on any ceilings. In addition, the absence of a plaster layer reduces the cost of its construction, and to accelerate the process of finishing - plaster has yet to dry, putty enough days.

For those who are closer to brick walls - article of warm plasterIf dealt with partitions, but the overlap of the cold and require insulation - useful information in the article of dry screed. In the video - installation of partitions from silicate blocks.
