We’re delighted to announce that SIP Build UK has been shortlisted for the Custom & Self-Build Project of the Year category at the Structural Timber Awards 2025 for our work on The Gables.

The awards celebrate the best of timber construction across the UK, recognising innovation, sustainability, and design excellence. Winners will be announced on 1st October 2025 at the industry’s annual awards ceremony.

About The Gables

The Gables is a striking example of what structural insulated panel (SIP) construction can achieve. Built to meet the client’s aesthetic, thermal, and sustainability goals, it features:

Vaulted ceilings and a dramatic open stairwell for an airy, open feel.
Large glazed areas to maximise daylight and showcase views.
175mm SIPs delivering U-values of 0.15 without additional insulation.

Glulam beams integrated for both strength and visual warmth.

Rapid Build on a Tight Site

The home was built on a tight-access site next to a busy school—requiring careful planning and efficient logistics. Using small HIAB-offload vehicles and just-in-time panel deliveries, we kept the site organised, reduced traffic disruption, and ensured smooth progress.

Both the main house and annex (above a large garage) were installed in just 11 weeks, enabling follow-on trades to start earlier and helping to compress the overall build schedule.

Fabric-First Performance and Sustainability

The Gables was designed with a fabric-first approach, delivering high thermal efficiency straight from the building envelope.

Key sustainability and performance highlights include:

Part O compliance and TM59 modelling carried out early in design.
MVHR and underfloor heating working efficiently with the SIP structure.
Responsibly sourced PEFC/FSC-certified timber.
Low embodied carbon and minimal construction waste.

This approach not only reduced environmental impact but also ensured long-term comfort and low running costs for the homeowners.

A Collaborative Project

From concept to completion, the project was a team effort between the architect, main contractor, and SIP Build UK.

By taking full responsibility for design, engineering, and installation—including steels, Glulam beams, intermediate floors, and internal walls—we reduced risk, improved accuracy, and delivered a seamless, on-time result.

The client’s feedback says it all:

“SIP Build UK gave us absolute confidence from the start. The process was smooth, the result is stunning, and the house performs better than we imagined.”

How SIPs Keep Your Home Cool in a UK Heatwave

Alison Siddall — Wed, 02 Jul 2025 13:35:22 +0000

With UK summers getting hotter, overheating is a growing challenge in traditional homes. But with a SIP envelope, your building works with the weather—not against it. Here’s how Structural Insulated Panels (SIPs) deliver reliable, passive summer comfort.

High-Performance Insulation as Standard

SIPs combine OSB skins with a solid PUR or EPS foam core—providing a continuous, high-performance thermal barrier. This insulation slows heat transfer and helps your home stay cooler for longer, even during peak summer temperatures.

Airtight Build, Reduced Overheating

Factory-cut SIPs form a tight, accurate envelope with minimal air leakage. Less warm air in, less cool air out—so you stay comfortable without over-relying on mechanical cooling. Great for your energy bills and even better for your carbon footprint.

Minimal Thermal Bridging

In comparison to traditional construction SIPs provides a superior air tight solution off the shelf. No repeat studwork in walls in comparison to timber frame also means far less timber content and thermal bridging. SIPs are the superior fabric first approach.

A Comfortable, Stable Indoor Climate

Thanks to the airtightness and insulation, SIP homes maintain even temperatures and a consistent, healthy environment—no hot spots, no stuffy rooms. As one Southend client said:

“The house is consistent—you’re not walking into one part of the house and thinking it is chilly…” Consistency equals comfort—whatever the season.

Southend Client

Reduced Cooling Loads = Real Savings

With less heat ingress, SIP buildings often need minimal active cooling—even in a heatwave. Smaller systems, lower bills, better long-term sustainability. It’s smart building from the inside out.

Reduced Cooling Loads = Real Savings

Our SIP shells are typically weathertight in a matter of weeks. That means protection from summer downpours and summer heat—right from the early build stages. A quicker path to a comfortable, secure home.

Are modern construction methods better than traditional?

admin — Tue, 11 Jun 2024 15:04:27 +0000

In 2019, the UK government incorporated modern methods of construction (MMC) into its long-term policy for the construction sector deal. This initiative emphasises the importance of offsite manufacturing to achieve a 33% reduction in construction costs and a 50% reduction in the time from the initiation to the completion of new builds.

In this blog, we’ll be exploring the key differences between modern and traditional methods of construction and why there is continued growth for MMC.

What does modern and traditional construction mean?

A modern method of construction is the use of advanced technology, materials, and techniques in the construction industry. These methods have changed the way buildings and structures are designed, built, and maintained. They often involve prefabricated components, automation, and digital tools to streamline the construction process and improve efficiency.

A traditional method of construction is the use of conventional methods of building structures using materials like bricks, concrete and steel which are assembled on-site. This process typically requires more manual labour and is often slower compared to modern construction methods. Traditional construction methods have been used for centuries and are still the most commonly used in many parts of the world.

What are the benefits of modern construction methods?

One of the key advantages of modern construction is its ability to speed up the construction timeline. With the use of prefabricated components, buildings can be assembled quickly and with greater precision. This not only saves time but also reduces labour costs and minimises the risk of errors.

Modern construction methods are often more sustainable than traditional methods. By using eco-friendly materials, implementing energy-efficient designs, and reducing waste, modern construction practices help minimise the environmental impact of construction projects.

SIPs for modern construction

SIPs are a perfect example of a modern construction material that offers faster build times, superior insulation and high-quality structural integrity.

Structural insulated panels are arguably one of the most versatile modern building materials that can be used for walls, roofs and cladding. SIPs are commonly used to create housing, commercial and industrial buildings, education facilities, retail, hotel and leisure facilities.

At SIP Build UK we are the leading (award-winning) provider of Hemsec SIPs. Hemsec products are BBA-certified and extensively tested for structural and thermal performance, including fire resistance.

Ready to build a time saving project?

Although traditional construction methods have their benefits, modern construction methods such as SIP buildings offer more in terms of speed, efficiency, and sustainability. As technology continues to advance, modern construction methods will likely become even more prevalent in the industry.

What is the fabric first approach?

admin — Thu, 16 May 2024 13:23:12 +0000

A “fabric first” approach to building design means optimising the performance of building materials before considering mechanical or electrical building systems. This approach can help lower capital and operational costs and minimise maintenance needs throughout the life of the building.

A fabric first approach should optimise the use of high-performance materials such as Structural Insulated Panels (SIPs).

Building with a material such as SIPs can help to increase the building efficiency and performance of your building right from the very start.

Using SIPs in a fabric first approach provides:

A rigid thermoset polyurethane (PUR) insulation core forming for high-quality insulation
Panels that fit precisely together for an airtight building
A highly durable material for a strong building
Airtight and insulative properties for a thermally efficient building
Offsite fabrication for simplified site works

Can fabric-first buildings create zero-carbon homes?

The thermal properties of a Structural Insulated Panels (SIP) system, combined with reduced thermal bridging, increased airtightness, and low U-values, can reduce the energy needed to heat or cool a room by up to 50%. In most cases, it eliminates the need for additional technologies or conventional heating, relying on the natural efficiency of the building’s fabric. However, additional heating or cooling sources can be included if desired.

SIPs offer off-site manufacturing, minimal waste, and low environmental impact, making them an ideal construction solution for all self-build projects, including those built to Passivhaus standards.

By focusing on the fabric of the building first, designers and builders can create a more sustainable and energy-efficient structure. SIPs are a popular choice for the fabric first approach as they can help to achieve building construction and performance goals. Overall choosing a high-performance material such as SIPS first will result in a high-performance building that is comfortable, durable and environmentally friendly.

Ready to build a fabric first SIP home?

Whether you are building to Passivhaus standards or simply looking to create a more sustainable living space, SIPs offer a versatile and efficient solution. With their ability to help achieve building construction and performance goals, SIPs are a smart choice for anyone ready to embark on a fabric first approach to building their dream home.

How long does it take to build a SIP house?

Alison Siddall — Thu, 11 Apr 2024 15:16:35 +0000

As a modern method of construction (MMC), SIP homes have many benefits. One of the main ones is their quick build time – structural insulated panels can cut framing time by as much as 55% compared to conventional timber framing.

How long does a SIPs build take?

On average, 2-4 weeks on-site.

When it comes to constructing a SIP building, the timeline for completion can vary depending on the size and complexity of the project. Standard SIP houses can be erected in as little as 10 days, but a simple structure typically takes around 3 weeks to complete.

SIP houses can be categorised into three types which are:

Simple Structures

Structures that are simple in design have a limited amount of glazing and do not possess any unique feature windows. The building is stacked from storey to storey

Mid Range

Homes that are efficient and mid-range in cost have some feature windows and storeys that are stacked. They may also have a few architectural features to enhance their appearance.

Architecturally complex

Buildings that are architecturally complex require additional structures and have cantilevers. They may also have a large amount of additional structure to provide an elegant appearance.

Why is it faster to build with SIPs?

SIP houses are well known for their quick and efficient construction process. This is because the panels are prefabricated off-site and then assembled on-site, reducing the time needed for traditional stick-built construction. This not only speeds up the building process but also helps to minimise waste and reduce overall construction costs.

Structural insulated panels can be used for walls. roofs, cladding, floors and decking making it an all-in-one solution.

Ready to build your dream home?

Overall, the construction timeline for a SIP house can be relatively quick compared to traditional construction methods. With the help of SIP Build UK, you can have your dream home built and ready to move into in just a matter of weeks.

5 key benefits of homebuilding & renovating with SIPs

admin — Thu, 14 Mar 2024 15:17:31 +0000

If you’re planning to build your dream home, you may be considering using structural insulated panels (SIPs) as it’s a popular and modern method of construction for most self-builders. Not only do SIP homes look great, but they are also energy-efficient, which means that you can enjoy lower utility bills and a more comfortable living space. SIP Global Marketing Report predicts a 4.8% compound annual growth rate (CAGR) from 2024 to 2033, driven by the need for green buildings.

SIPs can be used in many ways for homebuilding and renovation projects such as self-build and new-build homes, roofs and extensions.

In this blog, we will be exploring the 5 main reasons why people choose to use SIP panels for their construction projects.

Top 5 benefits of homebuilding and renovating with SIPs

1) Build speed

SIPs are prefabricated panels that can be quickly assembled on-site, reducing construction time significantly compared to traditional building methods. This means you can move into your new home sooner and start enjoying it faster.

Standard SIP houses can be erected in as little as 10 days but typically we would expect a simple structure (limited glazing and no feature windows and the building stacks storey to storey) to take around 3 weeks.

2) Structural strength

SIPs are known for their high strength-to-weight ratio, making them durable and able to withstand extreme weather conditions. This provides peace of mind knowing that your home is built to last and can protect you and your family.

Structural Insulated Panels (SIPs) significantly surpass both timber frame and brick-and-mortar homes in structural stability performance.

3) Energy efficiency

SIPs have excellent insulation properties, which help to keep your home warm in the winter and cool in the summer. This not only creates a more comfortable living environment but also reduces your energy consumption and lowers your utility bills.

SIPs give you real control over your living environment and is one of the most sustainable homebuilding options.

4) Simplified site works

SIPs are prefabricated off-site, meaning that site waste and mess are reduced during construction. This means a cleaner and more organised building site, making it easier for contractors to work efficiently and effectively. Much greater productivity and quality is generally the result.

Fewer trades needed on-site lead to minimal vehicle movements, invoices and interfaces where items can go wrong.

5) Ease of follow-on-trades

SIPs provide a full and level surface for battens to carry finishing materials such as drywall, siding, and flooring. This makes it easier for follow-on trades to complete their work quickly and accurately, saving you time and money in the long run.

Examples of follow-on trades include electricians, plumbers, hvac installers and joiners.
