Installed in no time – door system made of profiles and rails.
The door system of the cabinets we present consists of door frames and guide rails fixed to the floor and ceiling.
The kit also includes …
Concrete mix in Hessian bags is sometimes used to build massive slabs or walls at the bottom of reservoirs by divers and to fill prefabricated structures with concrete. (made of thick fabric impregnated with bitumen). The bags are partially filled with fresh mixture and lowered under water to …
Glued into a light bow – plywood cover.
Making a rack for hi-fi equipment also requires the purchase of a properly finished glass, not requiring further processing. Glass plates must be cut to size and have carefully sanded edges. Much more interesting is in …
Concreting should be preceded by the determination by a specialized laboratory of concrete components and its recipe as well as checking the characteristics of the mixture produced under construction conditions.. All concrete additives (plasticizers, sealants and set retarders) should have approvals and be laboratory tested.
Water, w której …
Concrete should be used only from factories, which ensures strict compliance with the requirements for the production of a mixture intended for installation under water. The plant should produce a mix with a consistency appropriate for underwater concreting and in the case of high air temperature or long transport time, …
Underwater concrete structures are currently built on the bottom of the oceans at depths up to 1000 m. Up to approx 300 m are concreted "in situ". At greater depths - they are assembled from prefabricated elements made on land and connected under water with concrete joints there …
Because a steep flat roof is exposed to moisture from the outside due to rainfall, and from the inside by the water vapor flowing through the partition to the outside, therefore, over the living quarters of the attic, ventilated slotted flat roofs should be built instead of solid flat roofs. Roof ventilation is possible …
The thermal insulation properties of the partitions are characterized by the heat transfer coefficient, denoted by the letter U. This coefficient determines the amount of heat flowing through a m² of partition in time 1 hours, when the air temperature difference on both sides of this partition is 1 degree. Inverse of the permeation coefficient …
Due to the required height of the attic rooms 2,50 m and from practical experience shows, that hipped roofs with a slope of the roof below 35 ° do not make it practically possible to develop the attic for residential purposes. However, the use of attics is possible in roofs …
These roofs are a multilayer partition with a large angle of inclination to the horizontal. Thanks to the reduction of the attic space, formerly serving as an attic, to the narrow ventilated air space, the construction of the external partition of the building was created, which serves both as a ceiling and as a covering. Thus, this structure protects …
