Keeping extreme cold or heat outside is the main purpose of a house, so insulation is a key consideration when planning home construction. Building using structural insulated panels (SIPs) is a hot trend, enjoying a comeback in popularity.
What is at the center of most structural insulated panels (SIPs)?
When was the first foam-filled SIP created?
in the 1930s
between 1978 and 1981
What does the term CAD refer to?
computer aided design
computer altered density
What made construction using SIPs temporarily popular in the 1970s?
the energy crisis
rising homeowners taxes
the discovery of new insulation materials
How does polyurethane compare with expanded polystyrene as a material for an SIP foam core?
It is more expensive but a better insulator.
It is cheaper, but more flammable.
It is more water resistant and a better flame retardant.
What substance is sometimes used as a more eco-friendly core for SIPs?
How are houses built out of SIPs wired for electricity?
The wires are fed through special channels in the wall.
Wires run along the edges of the walls and are then plastered over.
All wiring must be run under the flooring.
Why do SIP houses often use gypsum board on the inside?
as a fire retardant
to strengthen the walls
What is one of the major benefits of building with SIPs?
It is highly customizable.
It is very lightweight.
It is readily available in most areas of the world.
What might cost more in a house built from SIPs?
waste on the construction site
What is the most important thing to look out for when building a house out of SIPs?
to keep it airtight
to ensure that the walls do not directly touch the ground
to make sure that the panels do not get wet
How can you prevent mold from growing in an SIP house?
by installing the proper ventilation system
by painting the inside with lacquer paint
by leaving minute gaps between the different panels
What type of trees produce the wood that is typically used for the outer layers of SIP?
Where should you place nails for hanging pictures in a house built from SIPs?
anywhere on the wall
only at seams between panels
in the top third of the wall
How can SIP construction extend the building season?
Once the shell is constructed, workers can work inside even during cold weather.
They are easy to produce, so changes can be accommodated quickly.
They are water resistant, so construction can take place in rainy weather, too.
