We’ve been working hard behind the scenes to make planning your next SIP build even easier.

Our website and configurator have had a fresh upgrade, with new features designed to help you visualise, plan, and understand your project before you buy.

One of the biggest additions is our new AR View feature. Once your drawings are completed, you can view your SIP building directly in the space where it will be built. We’ve also added AR View to the configurator, so you can see your chosen design in your garden before placing an order.

We’ve also introduced a quick building regulations guide. It asks a few simple questions to help you understand whether building control may be needed for your project.

It’s all part of making the process clearer, easier, and more accessible from start to finish.

Also for a limited time only, we're running a 5% off a total build, sign up today to view your unique discount code.

UltraSIPS — making SIP builds simpler.

02/06/2026

Thinking about building a SIP garden room, office, studio or gym?

Not all SIP kits include the same things, so it’s important to know exactly what you’re comparing before looking at price.

A typical UltraSIPs garden room kit can include the SIP wall panels, SIP roof panels, splines, fixings and breather membrane, with options like SIP floors, EPDM roof covering and delivery depending on the build.

Windows, doors, cladding and internal finishes are usually kept separate, giving you more flexibility to choose the look, budget and final specification that suits your project.

We’ve put together a simple guide explaining what’s normally included, what may be optional, and what to check before ordering.

Do SIP panel builds need Building Control?

The short answer: it depends on what you’re building, where it’s going, how big it is, and how it will be used.

A small detached garden office or hobby room may be exempt if it meets the right conditions. But extensions, annexes, sleeping accommodation, larger buildings, serviced buildings, commercial spaces, and projects with big structural openings are much more likely to need approval.

SIP panels themselves aren’t the deciding factor. Building Control looks at the finished building: structure, fire safety, insulation, ventilation, drainage, electrics, glazing, foundations and overall use.

If you’re planning a SIP garden room, extension, annexe, workshop or garage, it’s worth checking early rather than changing the design later.

Thinking about a SIP garden room, office, gym or workshop and trying to keep costs down?

You don’t always need brand new windows and doors. If you’ve found second-hand, surplus, ex-display or wrong-order glazing, UltraSIPs can cut your SIP panel openings to suit your supplied dimensions.

The key is measuring accurately: overall frame width and height, sill or threshold details, opening direction, hinge side, photos, and where each item will sit in the wall.

It’s a smart way to save money without cutting corners: clean up the frames, replace tired handles or locks, check safety glazing where needed, and put more of your budget into a strong, insulated SIP shell.

We’re proud to announce that the new UltraSIPS website is now live.

After months of work, we’ve completely redesigned everything from the ground up to create a faster, clearer and more user-friendly experience for our customers. Every part of the platform has been rethought — right down to what the end user will actually see and use throughout their journey.

One of the biggest improvements is our new system designed to make SIP building far more accessible, helping even the most novice users feel confident when planning and installing their build.

We’ve also invested a huge amount of time into developing our new configurator tool, allowing you to design your own build online and receive a very close pricing estimate in real time, subject to final drawings and structural sign-off. It’s a powerful way to explore your options, refine your design and understand costs before moving forward.

So we all know there's a price hike for insulation, but would you like to know why? Found out at

PIR insulation prices are rising in 2026 because energy exposure, shipping disruption and chemical feedstock pressure are pushing many product lines higher across the market.
