What are SIP panels?

Structurally Insulated Panels

Structural insulated panels (SIPs) have become increasingly popular for house extensions, garden rooms, work spaces and home gyms. SIPs are made of a liquid foam sandwiched between two structural facings, which makes them extremely strong, energy-efficient, and durable. They can be fabricated to fit nearly any building design, making them a versatile option for a variety of projects.

SIPs have been used since the 1930s in the USA and Scandinavia where they have become a mainstream building material for constructing homes. Now, they are being used here particularly for single-storey buildings and their popularity is growing rapidly, as people see the benefits of this eco-friendly and cost-effective construction material.

Single-storey buildings such as lean-tos, orangeries, home office buildings, annexes, garden rooms, home gyms, and summer houses are becoming very desirable as solutions to the needs of the modern family. SIPs are a great option for these types of projects, as they can be used to create energy-efficient, comfortable, and durable spaces.  The speed of erecting SIPs as opposed to traditional build can be 3x faster. What could take 3 months or more to build, would take just 4 weeks using SIPs.

Here are some of the benefits of using SIPs for house extensions, garden rooms, and home gyms:

  • Energy efficiency: SIPs are excellent at insulating, which can help to reduce your energy bills.
  • Durability: SIPs are very strong and durable, so they can withstand the elements.
  • Flexibility: SIPs can be fabricated to fit nearly any building design.
  • Cost-effectiveness: SIPs can be a cost-effective option for house extensions, garden rooms, and home gyms.
  • Speed of Build: SIPs are manufactured in factory conditions and delivered to site to erect.

If you are considering a house extension, garden room, or home gym, then SIPs structural insulated panels are the answer. They are a great way to create an energy-efficient, comfortable, and durable space.


Why use a SIP?

Structural insulated panels (SIPs) are lightweight and can often be placed directly on existing foundations, provided they are approved for this type of building. This can save money on the cost of substructures, structural steelwork, and load-bearing internal walls.

In most cases, a simple concrete base is sufficient for a SIP building. SIPs are also highly fire-resistant and resistant to pests, making them a safe and durable building material.

Once built, SIP structures are significantly stronger than traditional brick or timber-framed buildings. They are up to 3 times stronger than brick and 7 times stronger than timber. This makes them an excellent choice for areas that are prone to high winds or earthquakes.

Here are some of the benefits of using SIPs for building foundations:

  • Cost savings: SIP foundations can save money on the cost of substructures, structural steelwork, and load-bearing internal walls.
  • Ease of construction: SIP foundations are easy to construct, which can save time and money.
  • Durability: SIP foundations are highly durable and can withstand the elements.
  • Fire resistance: SIP foundations are fire-resistant and can help to protect your home from fire damage.
  • Pest resistance: SIP foundations are resistant to pests, which can help to keep your home safe from infestation.

If you are considering building a new home or adding an extension, then use SIPs – structural insulated panels. They are a great way to save money, improve the durability of your home, and protect it from fire and pests. They give you more space as the panels are slimmer and they look great. You can choose to have a brick slip exterior, cladding or render.

Benefits of SIPS

Exceptional thermal performance

Structural insulated panels (SIPs) are known for their exceptional thermal performance. Once installed, SIP panels deliver unrivaled insulation and airtightness, which will reduce energy costs over the building’s lifetime.

A SIP building envelope has minimal thermal bridging, which means that there are fewer gaps or holes in the insulation. This lends itself ideally to LEED and net-zero-ready building standards, which are designed to reduce the environmental impact of buildings.

Better Air Quality

Structural insulated panels (SIPs) offer improved indoor air quality (IAQ) because their airtight building envelope limits incoming air to controlled ventilation. This ventilation can be filtered to remove contaminants and allergens, which can help to improve the quality of the air inside the building.

In contrast, conventional stick-framed buildings have voids and thermal bridging that can cause condensation. This condensation can lead to the growth of mould, mildew, and rot, which can be hazardous to human health.

The airtight building envelope of a SIP home or commercial building helps to prevent condensation by reducing the amount of air that can flow through the walls, roof, and floor. This helps to keep the interior of the building dry and free of moisture, which can help to prevent the growth of mould and other contaminants.

In addition, the rigid foam insulation used in SIPs is a good moisture barrier. This helps to prevent moisture from penetrating the walls and roof, which can also help to prevent condensation and the growth of mold.

As a result of these factors, SIP homes and commercial buildings typically have better IAQ than conventional stick-framed buildings. This is because they are better able to control the amount of air that flows through the building and they are less likely to experience condensation.

Here are some of the benefits of improved IAQ in a SIP home or commercial building:

  • Reduced risk of allergies and asthma: The improved IAQ can help to reduce the risk of allergies and asthma, as well as other respiratory problems.
  • Increased comfort: The improved IAQ can help to make the building more comfortable to live or work in.
  • Reduced Energy Costs: The improved IAQ can help to reduce energy costs, as the building will require less energy to heat and cool.
