What are the benefits of a SIP extension?

SIP home extensions are speedy

The SIP system reduces construction times by as much as 50% compared to traditional building methods.

SIP extensions are incredibly versatile

SIP panels are pre-cut at our factory for fast installation and can be prepared in advance to give you total design flexibility, turning your home extension dreams into your reality. This construction method offers a complete range of building elements and can be mixed and matched with other building systems.

SIP panel extensions are extremely strong 

SIP construction is an advanced building system that has internationally recognised laboratory testing. The structural strength means it can withstand earthquakes, cyclones, and day-to-day family life. Living in the UK, we are lucky enough not to worry too much about extreme weather conditions, but it gives you peace of mind about the strength the SIP construction method can offer.

Other benefits of SIP construction include:

• A brick and block wall will require a wall thickness of 350mm to achieve a good level of insulation. SIP walls only require 147mm width, they provide a much slimmer wall construction. This will give you more internal floor space than any brick and block build, giving you a larger room to enjoy.
• Engineered structure leading to quicker installation time opposed to a traditional build
• Exceptional acoustic performance.
• Superb structural performance over traditional builds, giving up to 7 times the strength of a timber frame and 3 times stronger than brick-built structures.
• Exceptional thermal performance over a traditional build - A 147mm SIP wall panel will provide a U-Value of 0.18 W/m²K. This will reduce heating costs and improve the thermal performance of any home.
• Flexible design options.
• Fast construction.

SIP extensions for your home

Choosing a SIP extension often means staying in the home you love and preventing the stress and mayhem of buying and selling a house.

A SIP is a ‘structural insulated panel’. These panels can be used to build new homes and roofs and to add extensions to existing builds. A SIP Extension is a home extension using structurally insulated panels which have been prefabricated, measured, and cut before the start of the build.

The panels comprise an insulating Polyisocyanurate core sandwiched between two structural facings. Structural insulated panels can be used over more conventional building methods such as brick, blocks, or timber frames.

SIP panel extensions don’t have issues with shrinkage or settlement and defeat cold bridging problems associated with other forms of offsite construction. SIPs are compact, therefore, taking up far less space than traditional external wall builds, meaning you can maximise the space in your new home extension.

A SIP home extension is an effective and quicker way to add space to your home, as the SIP framework for an extension can be quickly constructed stopping months of disruptions you would normally experience from a traditional build.  This form of construction significantly speeds up the process of a home extension build.
