What kind of material GSP

In the process of construction and finishing works modern board materials are used extensively, steadily moving closer to the pedestal mastodon such as plywood, chipboard or wood- plate. And if the leaders of the demand for gypsum board and oriented strand board at all on hearing, cement-bonded particle less, but still skips, then a gipsostruzhechnoy is much less known. Meanwhile, and this material is widely used FORUMHOUSE participants.

GSP - production technology, characteristics

Gipsostruzhechnye plate (GSP) did not have time to get a great experience - we were first presented at the conference in Germany in 1982, production in Europe, launched in 1985, already the Finns, foreclosure on the material. We were all just came in 2010, and to this day in the country - the only production. On the one hand, a monopoly - can dictate terms, which is not very good, on the other - with them and demand is higher, than artisanal kontorok, and quality should be high enough to "other guy" is not responsible shift.

As part of the GPS only natural materials - gypsum (83%), wood chips (15%), water (2%). What is interesting in the plate do not go waste wood processing industry, namely wood, and always peeled. Special machine cuts it into chips, then it falls into the machine and is transformed into a thin, flexible chip, which is important, considering its reinforcing function.

Humidity particleboard weight specially adjusted to 80% so that after the connection with gypsum to obtain a semi-dry mass to which is added a small amount of water. From gipsostruzhechnoy mass plate is formed, whereupon the blank is sent into a press for curing, the final stage of slab are sent for drying channel. The result is a dense enough material for interior works with an extensive scope of application, and the because the wood is stronger reinforcement of paper, on this indicator it is gypsum competitor bypasses.

Generally, two release plates variety - conventional and moisture, 8, 10 and 12 mm and a length 0.5, 1.5, 2.5 and 3 m, a width of 1.25 m. The dimensions of plates fitted underneath analogs dimensions, which facilitates layout. Perhaps, on some databases available still have the whole range of sizes, but the plant is now on the issue of plates 8 mm both categories suspended.

application

Gipsostruzhechnye plate superior gypsum and plasterboard, not only for strength, they also effectively isolate the sound, so it is often used for this purpose. Which is confirmed by our users.

PurPur70 (FORUMHOUSE User):

Engaged in interior decoration of a GPS, I can say that in some cases their use is fully justified in terms of price / performance. For example, for the installation room septum - the wall is obtained a strong, wear resistant, readily undergoes mounting fittings and holds all. While in the room, you do not feel like for "cardboard"Attenuation is much higher.

In addition to walls, they veneer wall for fit, often in order to avoid time-consuming and protracted leveling plaster. Using the ceiling is justified when it is necessary to increase the sound insulation, because the weighing plate well. For the same floor - quite workable option, especially relevant in the systems of underfloor heating on hardwood floors and dry screeds. For this purpose, can be used as conventional plates and special, small-format elements of the floor screed (IRENA), they immediately are thickened and have a special bevel. GPS and applied in the skeletal housing construction, instead of the SIR, unlike which are non-combustible material, since the chips are uniformly protected gypsum.

DmitrySSS (User FORUMHOUSE):

For interior decoration chosen gipsostruzhechnye home plate, because the material is flame resistant, durable and retains heat well. Now, when we live, we can say that the house is warm and quiet, what happens on the street, you can hear only with the windows open. Small shelves hung directly on the plate, all right lasts.

When fantasy availability and reluctance to throw waste is very cheap material, it is converted into a universal.

Grig70 (User FORUMHOUSE):

I liked that it was not necessary to throw away anything, constantly doing all sorts of interesting things, then repair of the GSP rests with his son made a table tennis table. Welded frame piece have cut along the size, consolidated, primed surface in two layers.

Another bonus - it was not necessary to take out the trash.

installation subtlety

Technology mounting plate assembly is nearly identical to any dry finish - a wooden or profiled lath on the hardware, on the adhesive mixture directly to the grounds (if there are no large fluctuations). In terms of cuts with a GPS is more complicated than with the GCR, but they give jigsaw or circular saw. Increased dust formation is considered one of the main drawbacks of the material, as well as a lot of weight, but scrubbers and for one assistant to another negate these disadvantages.

Shelest82 (User FORUMHOUSE):

Trimmed house inside sheets GSP, liked the result - the walls are smooth, strong. While working with plates of wild some inconveniences noticed. Many have heard that much dusts when cutting, but it also repairs and chop wood - chips fly.

Another detail - to drown head screws, you first need to ream the hole, just to drive deep into metiz screwdriver will not work. Fasteners should enter only at a right angle and dive into the metal is not less than 1 cm, wood - two, a step between the fasteners - about 25 cm. To prevent cracks, it is advisable to lay plates in two layers, with Extension seams but if use thicker sheets can be dispensed and one.

Hotdad (User FORUMHOUSE):

GPS 12 mm has a strength comparable to the furniture chipboard, so that there are no two layers is not necessary, and almost any shelf \ hangers can be mounted on a sheet without intricacies.

Since simple grouting difficult to perform, during assembly between platens with smooth edges leave a gap of 5 mm and filled with plaster or filler. If slabs imported, with rebated edges - butt mounted, shpaklyuyut with reinforcing tape. Additional alignment plates are not required, and whether the entire surface to cover filler depends on the finishing layer - if painting or paper wallpaper, it is better to err, if the glass fiber, decorative tiles, wall paneling, panel or thick wallpaper (vinyl, nonwoven), you can do seams.

Ideal materials do not exist, each has its drawbacks as well as the deficit is not observed, the only limit - your wallet. According to our skilled craftsmen, gipsostruzhechnye plate - a decent option for interior applications.
