Guardian Extensions- LABC Approved

SIP Panel Extension Efficiency Information

Our extensions utilise the Kingspan TEK® Building System for the walls, which has environmental sustainability at its core. All of the components for a typical extension, e.g. panels and ancillaries, come from one source. Therefore there are fewer deliveries, less transport congestion, noise and traffic pollution, which reduces a project’s impact on the environment. In addition, a project will create minimal site waste, as kits are designed, cut and palletised in a quality controlled, factory environment.

The insulation layer is not interrupted by repeating stud work, so there is less repeating thermal bridging, yielding better thermal performance. The SIP panels are certified to BES 6001 (Framework Standard for the Responsible Sourcing of Construction Products) as `Very Good’. The insulation core of the panels is manufactured with a blowing agent that has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP).

For roofs we use the Guardian Warm Roof system, which is fully tested and approved to all thermal and structural standards. This high performance insulated roof system comprises of a pre-engineered lightweight frame, two layers of rigid insulation board, internal insulated plasterboard, exterior grade plywood and a vapour membrane. Altogether this creates a thermally efficient living space; keeping the warm air out in the summer and preventing the heat from escaping in the winter thus saving the amount of heat energy required to keep the room at an ambient temperature.

Complete Construction Efficiency

Finished constructions produce a superior U-value of just 0.16 W/m2.K with a total wall thickness of 275.5 mm. To achieve an equivalent U-value using traditional methods of construction the wall would have to be 453 mm thick. Thermographic imagery on completed roofs has demonstrated 100% thermal reliability and continuous insulation, with:

• No cold bridging

• No condensation risk

• No interstitial moisture risk

We had a leaking flat roof so I decided to get it fixed properly

We had a leaking flat roof so I decided to get it fixed properly with a new flat roof system that had a long guarantee. It has fixed the leak and I’m pleased I don’t have to worry about it now. Projects 4 Roofing also fitted a window in our bathroom, which gave us much more light in there. I’m really happy with the work that was done and would recommend others to get their flat roof fixed by them too. I was happy with the workmen, who were polite, left our property clean and tidy and turned up on time.

Replaced the old poly-carbonate roof on our conservatory

Projects4Roofing replaced the old poly-carbonate roof on our conservatory, with a new Guardian Warm Roof on my my home in Hatfield Heath, Essex. The fitters worked flat out for the 4 days. The project was quite challenging with an open area adjoining the conservatory but after consulting the manufacturers they were able to do it successfully. We are very pleased with the work and are looking forward to using the room all year round.

We Wanted To Update The Exterior Of Our House

We wanted to update the exterior of our house and generally bring it into the 21st century, so we chose to have HardiePlank Cladding fitted by Projects 4 Roofing. It has really smartened up the look of the house and we are extremely happy with the finished result. We would definitely say to others it is worth getting it done – in fact we have already recommended Projects 4 Roofing to our friends. We were very pleased with the service from Projects 4 Roofing – they arrived on time, were polite, left the outside of the house clean and tidy afterwards and did a great job.
