Our team works hand in hand with building contractors and directly with the client to get the job done right. The SIP systems are pre-cut, pre-packed and labelled ready for assembly up to delivery to site. Waste is minimal, and site delivery is reduced due to the full system being prepared by ourselves.
Our Designers and Engineers provide all construction types with the confidence that they are choosing a rigorously tested building system. As a delivery partner of Kingspan Tek we offer the most tested SIP system available in the UK including the BBA agreement Certificate, PSI values, Fire testing and standard details available in AutoCad format.
We can be part of your design team to help develop schemes and offer advice. We’re the UK’s most experienced SIP construction team and hold Professional Indemnity insurance.
We can help you design your SIP self-build.
Our accredited SIP system of building is timber based and manufactured off site so we offer you the benefits rapid construction. We will be manufacturing the kit while you’re busy getting the foundations ready on site. Once the delivery day is here the erection sequence is rapid, usually 2 to 3 weeks from sole plates to being wind/weather tight and that lets you commence with the outside finishes at the same time as the internal fit out.
SIPs offer numerous environmental benefits that contribute to sustainable building practices.
As the construction industry shifts towards net zero carbon strategies for building and developments, using SIPs for your next project can play a significant role in achieving net zero carbon for your next project.
Net Zero SIPs from McVeigh Offsite provide a highly insulated and thermal envelope, minimising heat loss or gain and subsequently reducing your energy consumption and overall carbon emissions.
Our SIPs for schools build system supports the creation of comfortable learning environments using energy efficient materials to meet Net Zero Carbon Targets.
At McVeigh we have developed a system that suits the construction of Schools and Classroom extensions.
See our SIPs for Schools and classroom extensions in the Projects section of our website for examples our work.
Early engagement with one of the team at McVeigh Offsite can ensure the project has undergone a critical value engineering process, maximising our knowledge and expertise to make quality and cost-effective decisions early on in your project.
At McVeigh we are a Kingspan Tek process partner and this puts us in a great position. We can offer piece of mind that the raw product is being produced by the industry leading manufacture with the all testing and quality checks that entails plus then the flexibility of a niche workshop facility.
