(Structurally Insulated Panels)

All of the structural insulated panels (SIPs) used in our home extensions are produced by ourselves, in our factory in Sandy, Bedfordshire. The panels are made from two parallel faces of Orientated Strand Board (OSB) and sandwich a rigid core of expanded polystyrene.

We use SIP panels to pre-fabricate as much of our home extensions as possible before being delivered to your home or site. This way of building is widely used throughout America and Europe and is quickly gaining popularity in the UK as being the most economical way of meeting the new standards set out in Part L of the Building Regulations, which focus heavily on the consumption of fuel and power. A SIP home extension is an advanced, highly regarded, modern timber construction.

Permitted Development or Planning Application?

This part of the process can create quite the cranial itch. In most circumstances permitted development will be the course of action but at Home Extensions we do have planning professionals so we can help/undertake any planning applications that may be required for your Home Extension. The best place to find additional information would be from your local planning authority and the planning portal site both linked here.

Eco Friendly, Energy Efficient, Quick Construction!

A SIP home extension is constructed by seamlessly interlocking the boards and joining them with sealant and splines of OSB. This ensures that no air or heat can pass between them and therefore provides a massively insulated home extension which is environmentally friendly, cuts energy bills and greatly reduces green house emissions (CO2). You will have better control over your air quality as the structure will keep out allergens, dust and even humidity.

The lightweight nature of the panels reduces heavy foundation works and means that most of your home extension can be constructed in our factory and delivered to you, speeding up the whole process and minimising the waste on site – in all, up to 35% fewer raw materials are used in SIPS buildings.

Excellent Insulating Properties

SIP panels have some of the lowest U Values (measure of heat flow) of any building material, therefore giving you a SIP home extension that is massively insulated. The seamless way in which the panels are interlocked reduces the presence of cold spots so your home extension is warm and cosy; and can be made fully habitable.

Flexibility of Design

With a SIP construction we can be flexible with our designs, so you can be guaranteed an individual build.
