SIP Panel Builds

Strong, lightweight, & incredibly energy-efficient.

Our Process

Seviour SIP Panel Builds

SIPs, (Structural Insulated Panels) are one of the most advanced building systems available today. These panels are made up of a rigid insulation core bonded between two sheets of oriented strand board (OSB), creating a structure that’s strong, lightweight, and incredibly energy-efficient.

At Seviour Timber Frames, we use SIPs for both homes and light commercial buildings. The panels are pre-cut and prepared in our workshop before arriving on site, which means we can assemble them quickly and cleanly, often getting the building watertight in a matter of days.

Why Choose SIP Panels?

Advantages of SIPs

Unmatched Energy Efficiency

SIPs offer up to 50% better thermal performance than conventional timber or masonry builds. That means lower heating bills and a warmer, more comfortable home, all year round. They also contribute toward net-zero and passive house standards.

Cleaner Indoor Air & Less Waste

Because the structure is so airtight, ventilation can be controlled and filtered. This helps reduce allergens, moisture, and pollutants inside the home. Plus, with precise off-site fabrication, there’s far less waste compared to traditional builds.

Fast, High-Quality Build Process

Every SIP panel is engineered to exact standards before it leaves the factory. That speeds up site work and reduces delays. Less time on site means lower costs for labour, scaffolding, and project management.

Testimonials

A few words from those who have used us

Rated 5 out of 5

“As a builder, I’ve worked with a few frame companies, but Seviour really impressed me. Materials arrived on time, perfectly labelled, and the erection crew were tidy and efficient. Will definitely be using them again.”

“We used Seviour Timber Frames for our self-build project and couldn’t be happier. Craig and his team were supportive from day one, always at the end of the phone. The frame went up in no time, and the finish was spot on.”

“Outstanding service and quality. The whole team were friendly, knowledgeable and patient. I was new to timber frame construction and they walked me through everything without any jargon. Highly recommend.”

“The oak joinery Seviour crafted for our kitchen extension was absolutely beautiful. You can really tell it’s been handmade by people who care. It’s now the feature of the whole space.”

“Very impressed by the whole package—great communication, clear pricing, and the structure went up quicker than I thought possible. The energy efficiency in the house since moving in has been brilliant too.”
