TECHNICAL DESCRIPTION
The buildings that we offer are constructed
on the basis of designs and descriptions which were registered at the
Polish Patent Office on 19 December 1997. They are all patent-protected.
- Purpose and
situation
Our buildings are detached, single-storey constructions with usable
lofts. They are constructed on plots were the ground water level is
below the foundations.
- Foundations
The foundations are situated below ground level. The continuous footing
is made of B20 concrete reinforced with steel rods (A-0, O12). The foundation
walls are made of concrete blocks laid with a flat joint of cement mortar.
- Outdoor walls
The construction of the walls is based on ground beams fixed around
the continuous footing with anchors. The wooden frame of the walls is
made of 12x12, 12x14, 12x16 and 16x16 cm pillars, beams and angle braces.
The insulation is made of two layers of foam polystyrene with a total
thickness of 15 cm. The outer side of the polystyrene is covered with
mineral plaster on a net. The inner part is covered with fire-proof
plaster-cardboard.
It is also possible to make the outdoor facades of the gables of wooden
panels.
The heat penetration ratio of the walls is U=0.34 W/m2xk.
In order to obtain U<0.3 W/m2xK the second 4 cm layer of
foam polystyrene is replaced with a 6 cm layer of mineral wool.
- Ceiling
The dimensions of the floor beams are 12x18 cm; the floor in the loft
is made of 32 mm-thick boards.
- Roof
A rafter roof frame with or without collar beams depending on the size
of the building; sloping: 45 degrees; standard roofing: tile-resembling
sheet (optionally: bitumen shingle, concrete or ceramic tiles, or thatching);
insulation: 15 cm-thick mineral wool; indoor soffit ceiling: 12 mm OSB.
The heat penetration ratio of the roof is U=0.27 W/m2xK.
- Indoor walls
Double-sided plaster cardboard on a steel or wooden grid.
- Doors and windows
Wooden doors and windows; double-glazing heat penetration ratio:
U=1.1 W/m2xK. Optionally: wooden shutters on all the windows.
- Gutters and
drainpipes
PVC; optionally: chains instead of drainpipes.
- Indoor stairs
80 cm-wide, single-curve, open pine stairs.
