How Tammik shell houses are built

Draft the project. In accordance with your wants and needs, we draft an individual project with solutions. Since the inner walls are nonbearing, then we are able to plan the interior according to your needs.
Foundation. A ferroconcrete foundation is poured with a heated tile foundation. The foundation is built in accordance with current building norms and proceeds with the architectural project instructions. A standard foundation is meant to be built on a sand surface and the filler surface is an anticipated 15 cm of crushed stone filler.

Housing framework. In the factory building, the framework for the wall elements is completed, from 50×150 mm baulks, with a wooden frame of 600m. Nails are used to connect the baulks. The supporting ground wood framework in the foundation is a deep sunken baulk. Rodent webbing is placed in the venting elements located in the lower edges of the walls. The wall elements are connected with 5×150 nails, with a fastening along the framework at every 600 mm. Every framework has a diagonal supporting beam of 25×100 mm installed for rigid support. Every finished frame has a wind breaking plate installed. The wind breaking plate is installed without open joint areas (all edges will be attached to the framework). Onto the wind breaking plate, a wind gap is attached – a timber lath 25×50. 3×90 Zinc nails are used to attach the lath. A planed weatherboard is attached to the lath. When installing the boards, there is room left for expansion, so that the board can expand when affected by dampness. The weatherboard is covered with a chip guard medium.

Ceiling space. The cross section of the installed supporting beam for the ceiling space is at least 140×140 mm. Under the supporting beam’s concrete plate is installed hydro insulation. The timber posts are connected with metal plates. To the main joist beam is installed three 50×200 timber baulks that are attached to each other with nails, bolts and washers. After that, 50×200 spine timber baulk is installed with ceiling sole spaces of 600 mm. To support the side walls, a dredged support beam of 25×150 mm is attached with nails. The ceiling sole spaces are supported by the dredged support beam, and are nailed to the wall elements of the framework. Metal bearings are used to attach the beam’s stair opening and spine baulk.

Rafters. Rafters are built inline with the roof at a 35 degree angle. They are made of 50×150 mm baulks. The rafter’s horizontal connecting beam – baulk is 50x100mm, and is attached with nails. Rafters are installed attached to the wall’s connecting beam at a spacing of 1200 mm and 600 mm. Installed to the ridge beam are the rafter spacing fixed bearings. With zinc roofing nails, timber fiber wind barrier plates, 12x1200x2700 mm are nailed in between the rafters in the sloping areas used for heating insulation. Wind barrier plates are also installed to the merging areas of the sidewalls and roof.

Roof. Onto the wind barrier plates on the rafters, are nailed timber roofing boards, with a measurement of 50×50 mm by 600 mm. The boards are installed according to the manufacturing factories instructions for “Onduline” roofing. The description only pertains to corrugated bitumen roofing plates. Under the roof ridge packing is installed. Ventilation occurs in the houses end walls through installed grating. Wind boxes are built into the roofs end walls. The space between the wall and the wind box in the roof’s sidewall is at least 10 mm in ventilation width. Rain gutters and pipes made of either stainless zinc or plastic, are installed.

Doors and windows. These are installed according to the manufacturer’s instructions. Window and door joints are filled with polyurethane foam. The manufacturer guarantees the quality of the windows and doors.

Heating. “Isover” glass wool is used for heating, or other brands that are equally has good. In the supporting framework of the outer walls, 150 mm wool insulation is installed (ISOVER- 560 KL). After this, into the supporting framework is installed a metal framework that is 42 mm thick and 50 mm of glass wool insulation. In the sloping area of the roof, on the inside of the rafters, a metal lath MP 27 with a measurement of 600 mm, is attached. In between the rafters is installed wool insulation (ISOVER 560 KL 200 mm). In between the metal lath is installed addtional (KIVIVILL 30 mm). Altogether, the roof’s sloping are has a total of 230 mm of heating.

In the roof’s horizontal area, 300 mm of wool insulation is installed. To the inside of the queen posts is attached a metal lath MP 27. Between the metal lath is installed an additional 30 mm of insulation. During the installation of the insulation, everything is tracked to make sure that ‘air bubbles’ do not occur.

Ventilation: In accordance with the project.

Interior work: Plaster millboard plates with a thickness of 13mm, are attached to the outer walls and the ceiling’s metal lath. To attach vertical plaster plates to the house’s interior corners and the outer vertical fluing of the window, a metal corner profile is used under 50×50 plaster plates. The window fluing is finished with plaster millboard plates, without windowboards. The walls are caulked in the joints using a special webtaping. It is painted twice with acrylic half-mate interior paint. The inner wall metal framework is 45×66. 13 mm plaster millboard plates are fastened to the framework using screws. Walls are painted with a half-mate acrlyic paint. To soundproof the inner walls, 66mm wool insulation is used. A wooden chip plate is attached to the ceiling space beams. On top of the wooden chip plate is losely added woodenfiber plates and on top of this, laminate parquet. To the roof beams is attached a metal lath with screws, and between the lath is 30 mm of insulation for sound proofing purposes as well as a 13 mm plaster millboard plate.

White smoot combs. The doors have MDF peripheral slats, with a width of 45 mm. The floor border strips are with a simple MDF profile, with a maximum width of 45 mm. On agreement, on top of the concrete flooring tiles, in the hallway, showerroom and toilet, is placed an electrical floor heating system, (which is not part of the standard package). All floors are covered with a 50 mm thick concrete layer and is levelled with surface flooring. It is finished with laminate parque flooring or it is tiled in accordance with the order.

A standard wooden stairway framework is completed. The framework is covered with plaster millboard plates, it is caulked and then painted. The landing and steps are finished using pine, with step grooving strength and is installed using rubber filling. The stairs are varnished 3 times with floor varnish, or are stained and then varnished 2 times.

ELECTRICITY, WATER AND SEWAGE: In addition to the before mentioned installation of floor heating, the following are installed acording to building code standards: 1 electric radiators – with mechanical thermostates taken into consideration, are installed into every room. The rooms where there is floor heating, there are no radiators. Electrical outlets are of a simple form (white) throughout the whole house, and there are 34 in the house (double outlets = 2 outlets). Lighting points and switches, every room has 1 (if needed in the living room, 2 lighting points). In the staiway are two wall lighting areas with a draft switch. On the exterior of the house will be placed to lighting points on the wall and a water-proof 1 220 V outlet. The outward haul from the washrooms and toilets are through the outer wall. If necessary, a fresh air space with a valv, without ventilation, can be established by the fireplace/stove through the outer wall.

The television cabel from the first floor living room is brought from the living room up under the roof. There is one television outlet on the first floor. Antenna is missing. To install telephones, 1 outlet is on the first floor and another is on the second floor. The telephone wire is brought into an electrical shield. Electrical shield is installed in accordance with the project, to the outer wall, near the entry. Ground circuit is installed. Electrical control measures are implementated and a measuring act is established.

Plactic aluminum or PVC pipes are used for the indoor plumbing. A pressure control of the pipes is done before closing the walls with plaster plates. In accordance with sanitation laws, ballcocks are installed in all the connecting joints. On the outer wall of the first floor of the house, is installed a hydrant with a ballcock, which enables to turn off the water in the winter time. Channeling is done with PVC pipes d50 and d110. A ventilation valve is installed. According to standards, there is a 150 boiler in the house. Enumerated works descriptions, are included jobs in the standard package. Exact work listings will be fixed on the Work Contract additional documents.
