47mm Structural Insulated Sandwich Panel (SIP) is a construction board consisting of 35mm PIR foil faced rigid foam core sandwiched between two 6mm structural plywood facings.
SIPs are made of polyisocyanurate (PIR) core with a composite foil facings bonded to 6mm WBP grade plywood sheathing boards on both sides using solvent free polyurethane adhesives.
Structural insulated panels are 2400mm x 1200mm square edge profile boards which can be joined together without any special shaping with the most basic and simple butt joint technique.
SIP'S are extremely strong, energy efficient and cost effective solutions designed to provide high levels of thermal insulation in one easily applicable product available in standard 8x4 size.
The thermal conductivity of the PIR foam core insulation board is 0.022 W/mK (Lambda value).
The thermal conductivity of the 6mm WBP Plywood is 0.13 W/mK (Lambda value).
We don't recommend using our SIP's for external wall construction due to the square edge board profile.

Product Features Structural Insulated Panel (SIP):
· Composite Construction:
Consists of a polyisocyanurate (PIR) rigid foam core, foil-faced for enhanced insulation, sandwiched between two 6mm WBP grade structural plywood facings.
· Dimensions and Profile:
Standard panel size of 2400mm x 1200mm with a square edge profile for simple and quick installation using basic butt joints—no special shaping required.
· Strong and Durable:
Engineered for structural integrity, combining plywood facings and high-performance PIR core to provide excellent strength suitable for floors, walls, and roofs.
· Thermal Efficiency:
Low thermal conductivity of the PIR core at 0.022 W/mK and plywood at 0.13 W/mK, ensuring high levels of insulation and energy efficiency in buildings.
· Eco-Friendly and Cost-Effective:
Designed for long-term energy savings, reducing heating and cooling costs while supporting environmentally responsible construction.
· Versatile Application:
Ideal for interior walls, floors, and roofing systems but not recommended for external wall construction due to the square edge profile.
· Moisture Considerations:
Panels can be vulnerable to moisture damage; recommended to use additional moisture-resistant panels or waterproof membranes in high-humidity or external environments to protect the SIPs.
· Solvent-Free Adhesives:
Bonded with environmentally friendly, solvent-free polyurethane adhesives for safe and strong panel assembly.
Thermal conductivity is dependent on facings and product thickness.

We deliver insulation materials to Mainland UK only. Deliveries to Highlands, Northern Ireland, Isle of Wight etc.. might be possible at additional cost.
We offer free delivery on most of the orders above £300 (excluding VAT) (except special products - shipping cost via courier - products marked ''Request A Quote'')
Delivery of some insulation materials might be extended due to the current situation (Covid-19, stock shortages, allocations).
If you need materials quickly please contact us - we will do our best to help you source materials needed.
We do not deliver on weekends and bank holidays. Sometimes we can deliver on Saturdays - please check with us before placing the order.
If you need any further information please contact us tel. 02081910776
We can help to calculate price per m2 or linear meter (one meter in length) cost, please just contact us via phone 02081910776, email or live chat. Alternatively, you can work it out yourself quickly and easily: to get cost per meter square please divide price shown in orange area by ''Required area (m2)'' Example price of £28.80 divided by board coverage 2.88m2 = cost of £10.00 per m2.
INSTALLERS
No matter whether you choose a local installer or a national company, there’s a few tips to help you find the right installer for your home insulation improvements, such as asking for recommendations and making sure that they’re part of a certification scheme. This makes sure that they have the right skills and standards of workmanship to carry out the installation, and you can be sure that they know exactly what they are doing.
4 TIPS FOR CHOOSING THE BEST INSULATION INSTALLER
1. Thermal inspection picture in portfolio
It’s worth seeing a installer’s previous work. There’s no harm asking if you can see any properties nearby that they’ve installed insulation in. Best way would be to see Infrared Thermal Imaging Inspections. Thermal cameras spot small, but key changes in temperature in different areas of a house, identifying problematic areas that the human eye never could and some that a visual inspection could only hypothesize.
2. Reviews
Along with checking recommendations and previous work, finding reviews online can often be a great way to find out if they provide a good service or not. However, it’s best not to solely rely on reviews you may find or review websites, as there’s no controlling who writes them.
3. Compare prices
Comparing prices will also ensure companies can’t take advantage of you and give you a fair price.
4. Word of Mouth
The best way to find a great insulation installer is through recommendations. Make sure you ask friends and family. They will most likely give you their honest opinion and can tell you from first hand experience.
Whether you require a wall, cladding, external wall, loft or floor insulation fitted, you can find and hire your local insulation installers from popular UK web pages. A simple internet search will return thousands of potential installers near your area.
