Warm Sustainable Living
Improve your Family's Health with MAXRaft® by having a home that has a comfortable temperature all year round.
Homes today need to have more than just an aesthetic pleasantness about them, they need to provide concrete benefits to you and your family. MAXRaft® is designed to help you live in a home with greater levels of comfort, increased energy efficiency and health benefits for you and your family.
MAXRaft is the most insulated slab system on the market today. Simply compact the ground, level it and put up bracing, and the site will be ready to set polystyrene profiles out. After reinforcing is added you are then ready to pour in a fraction of the time taken by conventional methods. Can be used in conjunction with any building system.
MAXRaft® is the only FULLY insulated slab system available on the market today - minimal thermal bridging.
This secondary floor system is set up in a matter of minutes. Made to specifications in the factory it is then simply a case of laying out the tongue and groove joined sheets over propping. Add your pre-specified reinforcing then pour. This product is suitable for all types of secondary floor applications including above garages, decks, and a variety of large-spanning situations.
It's not just us who say foundation insulation is the way of the future, click here to read an eZED blog on the issue.
At MAXRaft®, we want you to be sure that your home is of the highest quality. To this end, we have been through the rigorous CodeMark accreditation system to give you peace of mind that our systems have been independently tested.
Maximum Energy Efficiency
As heating costs grow, and the environment impact of fossil fuel use becomes clearer, using a MAXRaft® insulated foundation is more energy efficient and can save you significant amounts of money on an ongoing basis, all the while reducing your carbon footprint.
Thermal Break Insulation
MAXRaft® insulation provides a complete thermal break between your foundation and the ground around it. this reduces the transfer of energy from your home into your flower beds, allowing you, not the surrounding environment, to dictate the temperature within your home. If a thermal break is not created, you could lose the same amount of heat as leaving a window open in the middle of winter. Why heat the atmosphere?
Through using the right insulation you can save hundreds, even thousands, per year off your energy bill to heat your home. Floor insulation is the easiest and most cost effective way to retain heat in your home. We have found that an Insulated floor combined with In-slab heating is by far the cheapest, most rewarding way to heat your home. It should cost around $100 per month to heat the average sized home! One of our clients has calculated the cost of underfloor heating for his home at 60.2c/m2 per month. Forget the expensive wall hung heat pumps, warm your whole house from the ground up.
Even without underfloor heating, a MAXRaft® insulated concrete foundation can act as a heat sink for your home. This regulates the temperature changes in a room allowing you to maintain a consistent, comfortable temperature.
As an official partner of Homestar™, MAXRaft®'s insulating properties have been recognised by those charged with implementing New Zealand's energy efficiency ratings. MAXRaft®'s fully insulated foundations can help you gain a Homestar™ rating of 6 and above, an important consideration when valuing a home as more and more people become aware of the value an energy efficient home can create.
Outside cold can easily travel through a traditional foundation, causing thermal bridging, and creating uncomfortable cold spots within your home. MAXRaft® fully insulated foundations offer superior performance when it comes to thermal bridging, resulting in consistent temperatures throughout your home with reduce cold spots, which optimizes energy efficiency.
People feel more comfortable when the heat is at their feet, and it is slightly cooler at their head. By allowing the slow release of heat from your foundation, MAXRaft® maintains this balance ensuring you enjoy that warm comfortable feeling.
The additional heat retained in your foundation also reduces the ability of damp to rise at the juncture of wall and foundation. This in turn leads to a warm, comfortable living environment without that damp presence in the air.
Reducing the heat loss from your home ensures it is warmer, drier & healthier which reduces its occupants' exposure to cold and moisture. There has been much study on the triggers for asthma sufferers and it has been proven a properly insulated, warm, dry home greatly improves the symptoms.
A warm floor is also very important for people with poor circulation, those who are inactive for long periods of time, for children who live closer to the floor, and for babies and the elderly as they cannot keep themselves warm as well as healthy adults.
World Health Organisation recommends a minimum of 18°C for living areas and 16°C for bedrooms, 30% of New Zealand homes being built today don’t meet these standards. MAXRaft® makes it easier to maintain these temperatures and reduce those doctors bills.
As seen above, MAXRaft® helps retain heat in the foundation and thus leads to a higher temperature at the junction of wall and slab when compared to traditional methods. This higher temperature reduces the likelihood of moisture condensation building up in these corners, and thus avoids the buildup of spotty mold.
MAXraft® has been approved for use in Christchurch's TC1 and TC2 zones. It provides the same structural integrity as waffle floors, while providing superior insulation for your home,
Prior to the Christchurch Earthquake we had installed multiple MAXRaft® floors. They performed well and are all still all being occupied today. One of the floors was in the epicentre of the earthquake in Salisbury Road, most of the building around it had to be demolished while it is still standing.
The design of our infill, combined with the perimeter footings, allows underfloor heating to work up to 40% more efficiently by lessening the heat loss each time it nears the outside of the house. The effectiveness of a MAXRaft insulated slab used in conjunction with underfloor heating was discussed in the Autumn 2014 edition of the Building Innovations NZ magazine (page 5).
Not only does MAXRaft increase the efficiency of underfloor heating, the installation of the underfloor pipes themselves can be done in a quick and effective manner by attaching them directly to the MAXRaft, reducing the installation time and allowing the concrete covering to be maintained at a regular 100mm depth.
Exposed Concrete Floors
MAXRaft is a must if you are grinding or polishing your concrete floor. The slightly lengthened curing process arising as a result of the MAXRaft® insulation results in a stronger, more crack resistant floor. With correct positioning of eaves and windows, an exposed concrete floor with MAXRaft® insulation can act to warm up your home in winter and cool it in summer.
“In our experience MAXRaft® is one of the most efficient ways of prepping a concrete slab than any other system. There is limited bracing and boxing required as the MAXRaft® is prefabricated in the factory and delivered onto site ready to be installed. Its rating is a R4.5 which makes any building using it extremely well insulated. Highly recommended.”
