Why buy an RD SIPs house kit?

Building a home is one of the biggest investments you’ll ever make. Our Structural Insulated Panel (SIP) house kits are designed to make that build faster, warmer, and more predictable—without compromising on quality.

A faster build (and less disruption)

SIP construction is all about speed and accuracy. Because the structure is pre-designed and supplied as a coordinated kit, you can get to a weather-tight shell far quicker than with traditional blockwork or timber framing.

• Faster to erect than many traditional methods
• Earlier weather-tight stage helps protect your build
• Shorter time on site can reduce labour costs and disruption

A warmer, more energy-efficient home

SIPs create a highly insulated envelope, helping you keep heat in during winter and out during summer.

• 147mm PUR-bonded panels can achieve a U-value of 0.18 (UK building regs compliant)
• Reduced heat loss can mean lower running costs over the life of the home
• A more consistent internal temperature for comfort

Professional-grade panels with real certification

A house kit is only as good as the system behind it. RD SIPs supplies certified panels and works to audited standards, so you’re not relying on guesswork.

• Structural Timber Association (STA) member
• CAT G: SIP Mark Systems
• ISO 9001 certified
• STA Assure Silver
• Made in Britain

Predictable quality: made in controlled conditions

On-site waste, weather delays, and inconsistent workmanship can all hit traditional builds. SIPs reduce those variables.

• Panels are produced in controlled conditions
• Full material and production traceability
• Panels can be dry-fitted in the workshop to reduce site errors
• PUR auto-bonding helps prevent delamination

Designed for real-world builds (not just perfect drawings)

Whether you’re a self-builder or a contractor, you want a kit that’s practical to install and supported by people who understand the details.

• Guidance through design and planning
• Clear advice on foundations, openings, and roof design
• Support during installation (including best-practice fitting guidance)

Less waste and a more sustainable approach

SIPs can be a more efficient way to build—both in terms of energy performance and site waste.

• Zero On-Site wastefrom the SIP design approach
• SIP builds can save45% more CO₂vs. stick framing (typical comparison)
• Energy payback around 5.1 yearsand greenhouse gas payback around3.8 years(typical comparison)

Clear lead times and straightforward supply

We’re set up to support projects of all sizes—from small builds to complex, multi-angle homes.

• House projects typically supplied in 4–8 weeks (subject to design and scheduling)
• UK-wide supply available
• Transparent communication on what’s in stock vs. made-to-order
