What is ‘POLYCAM House’?

It refers to a building that is constructed by combining the structural insulation panels (SIP) in the patented CAM-LOCK tightening method that use rigid polyurethane foam as insulation core and OSB plywoods are attached on both sides.

The POLYCAM House that uses the SIP which is a wall unit without erecting wooden frames reduces construction period considerably because there is no need to construct walls and also no need for curing of insulators on site.

It can be constructed more than double quickly compared to the existing wooden houses.

Besides, since it goes through a process of filling polyurethane foam with very high pressure at the dedicated facility compared to polyuurethane that is generally cured on site, its insulation performance and quality are exceptionally excellent and management costs such as costs for heating and cooling etc. are reduced significantly.

It is a building that is the nearest to the zero energy building by quick construction period and excellent insulation performance, solar light modules etc. that can be selected as an option.

Is the POLYCAM House made of woods?

Yes. it is. When registering the POLYCAM House, it is registered as a wooden house.

The POLYCAM House which is a house that is constructed by combining the structural insulation panels (SIP) that use hard polyurethane as insulation core and OSB plywoods are attached on both sides in the patented CAM-LOCK tightening method is a house that fast construction period and excellent performance etc. of modular houses are combined with advantages of wooden houses by using OSB plywoods that are used in general wooden houses.

Is the insulation performance excellent?

he POLYCAM House is one of houses with the most excellent insulation performance among houses that are currently constructed.

The refined rigid polyurethane foam that is used for the POLYCAM House is much more highly-enriched and better quality than polyurethane foam that is cured on site.

Polyurethane foam is an insulator with the lowest thermal conductivity among currently commercialized insulators (thermal conductivity 0.019W/mk).

Thermal conductivity of reinforced concrete that we generally know is approximately 2W/mk, and the one of red bricks is about 0.96W/mk.

Since it can’t have sufficient insulation only by these structures, insulators with low thermal conductivity upon construction of a building are used, and thermal conductivity of a heat insulating board made in extruding process that is commonly used is 0.027W/mk and the performance of hard polyurethane of 0.019W/mk is exceptional.

The excellent insulation performance is one of the biggest reasons why the POLYCAM House is used for the project of constructing lodgings for the athlete support group in the winter olympic game at Pyeongchang in 2018.

As a result of experimenting house performance by U-construction management engineering research institute at Seoul National University of Science and Technology, it corresponds to Energy Efficiency Rating 1+.

Is it possible to purchase only materials (SIP) and construct it directly?

Yes, it’s possible.

The structural insulation panels (SIP) that use hard polyurethane as insulation core and OSB plywoods are attached on both sides are easy to be constructed in the CAM-LOCK method which is the patented tightening method without separate tools.

The SIP of SY Housing that can change the existing construction method is an architectural material which is a little more convenient, safe and has excellent performance.

Inquiries about purchasing materials are also welcomed at any time.

If you contact an agency or the main office, we’ll be more than happy to provide information on how to purchase and construct in detail.

 

I’d like to build a house with POLYCAM House, and what is the procedure?

You may consult at an agency about all stages of constructing a house from design, construction to moving in.

SY Housing has established 70 or so agencies across the country, and has supported for smooth progress such as introduction of cooperative constructors etc.

A start for building your own house, find an agency of SY Housing!

May I get the unit price per Pyeong?

In general, the construction costs vary widely according to finishing materials such as internal finishing materials, external finishing materials etc. and selecting options for windows and other materials.

But, regardless of the scale of construction, there are basically the required costs so the unit price per pyeong may be lower for a large house than a small house.

For more details, after consulting closely the area and options that you want with an agency or the main office, it will be possible to calculate the unit price more precisely.

I’m curious about how to heat the floor.

Both dry and wet heating methods are all applicable.

It is possible to construct in line with options that you want, and more details and prices can be determined by consulting with an agency.

Would it be better to have an agency that will conduct design and construction nearby the site?

Not necessarily.

Since the most important thing in the process of building a house is a design phase, and it would be better to consult with an agency closely that is located at a place where it is easy for you to consult in advance.

Since SY Housing is available to deliver materials without any restriction on construction sites by distribution network and agencies across the country, you may find any convenient agency to have discussion.
