112mm Insulated Sandwich Panel Ply SIPs is used in floors, walls and roofs, made of 100mm polystyrene insulation sandwiched between 6mm structural plywood facings.

Our structural insulated panels are 2400mm x 1200mm square edge boards which can be joined together without any special shaping with the most basic and simple butt joint technique.

SIPs 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 6mm WBP (weather and boil-proof) grade Plywood Facings is 0.13W/mK (Lambda value).

The thermal conductivity of the Expanded Polystyrene EPS70 core insulation board is 0.037W/mK (Lambda value).

6mm Plywood density is 680kg/m3 – 700kg/m3, so it's an ideal sheet material for structural projects.

EPS70 core is moisture resistant, rot proof, unaffected by bacteria, mould or fungi and is non-toxic, non irritant and odourless insulation, compatible with most building products.

We don't recommend using our SIP's for external wall construction due to the square edge board profile.

Plywood and EPS SIP Sandwich Panel Features:

 · Three-layer composition: EPS70 expanded polystyrene insulation core bonded between two 6mm Plywood facings.

 · Standard size: Panels are 2400mm x 1200mm with square edge profiles for simple butt joint installation.

 · Thermal conductivity of the 6mm WBP (weather and boil-proof) grade Plywood is 0.13W/mK (Lambda value).

 · EPS insulation core has a thermal conductivity of 0.037 W/mK.

 · Strong and durable: Ideal for structural applications such as floors, internal walls, and roofs.

 · Environmentally friendly: Provides long-term energy savings and is ecologically conscious.

 · User-friendly installation: No special tools or joint shaping required—easy handling and setup.

 · Compatible with most common building materials.

 · Lightweight yet robust: 6mm Plywood density of 680-700kg/m3 makes it an excellent structural sheet.

 · Cost-effective construction solution: Combines strength, insulation, and ease of use in a single panel.

 · Limitations: Not recommended for external wall construction due to the square edge profile.

 · Adhesive bonding: Solvent-free polyurethane adhesive ensures strong and eco-friendly panel assembly.

 · Moisture considerations: SIPs may be vulnerable to water damage—additional waterproofing or moisture-resistant layers are advised where needed.

 

Thermal conductivity is dependent on facings and product thickness.

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.
