Say goodbye to costly structural engineers and architects as all structural calculations are taken care of by specialist hup! software. Want to include large spans of doors in your design? We’ve made that cost effective too! Include doors up to 5.6m wide without the need for expensive lintels. Your hup! builder can take care of your entire hup! Flat Roof extension project without the need for any specialist labour so your hup! Flat Roof not only looks stunning, it also offers fantastic value for money. With the hup! Flat Roof you can be assured of a high quality finish every time thanks to advanced Ultraframe precision engineering and offsite manufacturing in a BBA approved factory. This offsite manufactured approach means that you can be assured of a consistent, high quality finish and a fast, hassle-free build. Your hup! Flat Roof will arrive at your home as a kit of parts, ready for your hup! team to build. A common misconception is that there are not many options for personalisation with a flat roof but with the hup! Flat Roof this couldn’t be further from the truth! Add lanterns or skylights wherever you like in the roof design to bring in natural light where you need it most. On the exterior, choose from a range of attractive fascia designs to bring interest to the roofline, or choose the extended soffit option for the perfect place to house external lighting – the ideal way to highlight your hup! extension in the evening. Energy efficiency is at the heart of the hup! Flat Roof. BBA approved Ultrapanel technology provides incredible energy efficiency to ensure a space that is the ideal temperature to enjoy all year round. Offering a class-leading U-Value of just 0.12W/m2K, there is also a choice of low U-Value glazing for the rooflight options to further insulate your hup! Flat Roof extension and offer solar control to help keep energy bills low. Thermal breaks throughout the roof and a vapour control layer ensure that condensation is eliminated for a harmonious interior environment.Value for money
