Achieving Passivhaus performance doesn’t need to involve complex assemblies, deep build‑ups, or multiple insulation layers. SIPit’s 245 mm OSB‑PU structural insulated panels provide a simple, predictable, and certifier‑friendly route to ultra‑low energy construction — delivering both thermal performance and airtightness with minimal detailing. With a U‑value of 0.09 W/m²K, the 245 mm SIPit panel meets and exceeds the fabric requirements for Passivhaus envelopes. Combined with

Scotland’s 2027–2028 building regulations are moving toward a Scottish Passivhaus‑equivalent standard, with significantly tighter fabric performance requirements. This signals a clear shift to lower U‑values, higher airtightness, reduced thermal bridging, and lower embodied carbon. Many construction systems will need multi‑layer insulation build‑ups to meet these new targets. SIPit’s PU SIP panels do not. Our large-format PU SIPs achieve these U‑values as a single engineered

This guide explains everything UK self‑builders need to know about building a garden room using SIP (Structural Insulated Panel) kits. It covers sizes, roof options, tools, planning permission, buying direct from the manufacturer, and how SIPit supports you throughout the build. What Is a Self‑Build Garden Room? A self‑build garden room is a standalone insulated building constructed by the homeowner, usually using a prefabricated SIP kit. These rooms are ideal for home office

PU SIP, embodied carbon

When people talk about “low‑carbon insulation”, they often assume natural materials automatically win. But GWP (Global Warming Potential) doesn’t work that way. The numbers depend on how the material is made, not whether it’s petrochemical or natural. GWP matters because it tells you how strongly a material contributes to global warming compared to CO₂, and it’s the key metric used in EPDs, F‑gas rules, and whole‑life‑carbon assessments. For PU, GWP is especially important be

In the UK, fire‑rated external walls are becoming more complex, more regulated, and more expensive to build. Whether it’s a holiday lodge, a commercial unit, a school, or a multi‑storey car park, the requirement for robust, tested, and certifiable fire performance is no longer optional — it’s fundamental. This is exactly where the SIPit‑FR panel stands apart. A Stand‑Alone Structural Panel — Tested on Both Sides SIPit‑FR is the only polyurethane‑core SIP panel in the UK that

SIPit‑FR is a structural insulated fire panel designed for high‑risk wall applications in residential buildings. It provides a fully tested REI 60/60/60 rating under BS EN 1365‑1, with fire resistance proven from both sides. Where it’s used Boundary walls close to site boundaries or neighbouring properties Party walls between apartments or attached dwellings Any wall requiring 60‑minute structural fire resistance Key advantages REI 60/60/60 performance in a single factory‑mad

Holiday lodges may look like lightweight leisure buildings, but in regulatory terms they are commercial sleeping accommodation. That instantly raises the bar for fire safety. Guests are unfamiliar with the layout, lodges are often positioned close together, and boundary distances can be tight — all of which trigger stricter requirements under the Scottish Technical Handbooks. This is why lodge designers and operators increasingly need to think like commercial developers, not

Why SIPs Are the best Route to Your self build project. Spring is when self‑build dreams finally start to feel real. The weather turns, the ground dries up, and suddenly that garage, garden room, or holiday lodge you’ve been planning all winter feels within reach. The only question is: how do you build something warm, strong, and long‑lasting—without spending months on site or blowing the budget? That’s where Structural Insulated Panels (SIPs) come into their own. At SIPit S

At SIPit, we’ve always believed that smarter construction comes from combining the right materials in the right way. Over the past few months, we’ve been working closely with our partners at Eco Cork Solutions to develop a breakthrough external wall solution for commercial buildings, modular manufacturers and the holiday‑lodge sector. Today, we’re excited to share the results: A 1‑hour fire‑rated SIPit‑FR panel finished with a breathable, fire‑resistant cork render applied

Building a sustainable future is no longer just an option - it’s a necessity. As we face environmental challenges and rising energy costs, adopting sustainable building methods is the smartest way forward. Whether you are constructing a new home, developing a commercial property, or renovating an existing structure, choosing eco-friendly approaches can make a significant difference. In this post, I will share practical insights and actionable tips to help you embrace sustaina

SIP panels are a game changer in construction.

SIP has been around for decades and is renowned as a reliable, high performance, easy to install, sustainable, building solution. But what does 'Sustainable' really mean? We have broken down the different elements of this tried and tested SIP system, taking into consideration materials used, manufacturing process, installation and final building performance. SIPit OSB and PU Structural Insulated Panels The sustainability of the materials used:- The SIP is made with two exter
