Frequently Asked Questions
We’ve put together a bunch of frequently asked questions to save you time and effort.
Graphite SIP houses
Whereas in a timber frame building there is 40-60 cm of timber frame per board, in Modern SIP panels the
certified kvh wood is framed as 125 cm, so the insulation does not stop at every 40-60 cm,
insulates over a larger continuous area.
While traditional lightweight houses have stone/glass wool inside, Modern
SIP panel is made of graphite EPS polystyrene, which does not shrink like rock or glasswool, so
no thermal bridging can occur.
Where the soil quality does not require special priming (e.g. in the case of groundwater), it is sufficient to use strip foundation
for the structure.
The 16.4 cm thick SIP panels we build are built with 10 cm of rockwool, so the U-value of the walls
0.14 W/m²K, which is the passive house limit.
The fire protection against external fire is provided by a 100 mm thick rockwool layer installed on the outer plane of the SIP Panel.
In the case of an internal fire or a fire from the roof, the fire is directed to the inner plane or the 2 plies of fire-resistant plasterboard
installed on the inner plane of the building and on the lower plane of the rafters.
The fire performance is thus REI15 and REI20.
Any building can be constructed from SIP panels. Both traditional roofs and modern, minimalist style buildings can be constructed. Lightweight and with exceptional structural properties,
SIP panels are also ideal for building solutions, attic and multi-storey conversions.
Thanks to the new certification, Modern SIP panels can now be used to build multi-storey houses.
A 100 sqm house with a standard layout can be built turnkey in 180 days.
Thanks to our technology, work on the foundations can continue in dry cold weather until the building is ready to be closed. We always ensure the right temperature when using liquid materials for internal work.
Once a suitable waterproofing layer has been established, any type of cladding can be applied. In wet rooms, fire and water resistant plasterboard is still covered with liquid waterproofing.
This will ensure that water cannot reach the SIP Panel.
We use rockwool as external thermal insulation to achieve the heat transmission coefficient specified in our certification. Anything from stone cladding to plaster to wood cladding can be applied to this,
of course with the correct preparation for the cladding.
In our houses we install electric underfloor heating with a solar panel system, which is very economical thanks to the good thermal insulation system.
One of the biggest advantages of SIP houses is the airtight building structure. Thanks to this, these buildings have excellent thermal insulation,
but it is precisely because of the air-tight structure that a constant exchange of air must be ensured in the house. In all cases, this can be achieved by a heat recovery ventilation system,
which can be either decentralised – single room – or centralised. In each case, the mechanical engineers will recommend which ventilation system should be installed and used and when.
In Hungary today, the use of Modern SIP construction technology does not represent an additional cost for the builder.
Modern SIP panels manufactured by Költözzma Ltd. and the related building structures are covered by a 30-year manufacturer’s warranty.
Smaller objects can be fixed using plasterboard dowels, larger objects (e.g. kitchen furniture) can be fixed to the Modern SIP panel using plasterboard dowels and wood frame screws.
Yes, the SIP panel technology is particularly suitable for the construction of passive houses, as the wall layering of the Moder Sip panel has a value of 0.14 W/m2k, which is within the passive house value.
The design and construction of passive houses is partly different from conventional buildings, so please contact one of our colleagues for assistance on this topic.
Garfite insulation and the coatings used in the manufacture of Modern SIPs are resistant to attack by mould and microbial growth and therefore do not provide food for pests.
Modern SIP panels cannot be damaged by rodents or insects.
Roof structures with segmental sheets
For buildings of any size and masonry, a pitched roof can be used.
Roofs can be made from slate roofs, pitched roofs, half slate roofs, gable roofs, flat roofs.
The advantage of a nail plate roof is that it can span large distances, up to 25-30 metres, without the need for support, so that the internal layout does not need to be disrupted by support.
Thanks to its low pitch, 30-40% less timber is needed to build it.
As manufacturing takes place in a factory environment, the roof structure can be craned onto the construction site in 1 day, or in half a day for smaller simpler roofs.
They have a very high load-bearing capacity thanks to both the nail plate anchorage and the brackets.
As a shell, it can hold ceramic tiles securely, but can also be loaded with concrete tiles.
Solar panels can also be installed on the roofs.
No solid slab is required, the slab is supported by the lower belt of the truss support.
The nailing board is used to fix the wooden elements of the roof together. It is fixed to the timber from both sides by pressing.
Our quotation includes the manufacture of the roof truss in the factory, delivery to the construction site, cutting the structure into houses.
We can make it stackable by covering the support strip with OSB.
If you want a more cost-effective, faster, more accurate roof structure, the answer is yes.
