This is also known as warm deck as the thermal insulation is placed above the structural deck. This form of construction is the option most frequently used in the refurbishment and new build flat roofing markets as it eliminates need for ventilation. Additionally insulation may also be used to increase the thermal properties and/or supplied as a tapered scheme to enhance inadequate falls on an existing flat roof. See similar questions...

Firstly we must define a warm roof construction and a warm roof space. To be classed as a warm roof construction, flat or pitched, the insulation must be positioned above the roof timbers or deck. A warm roof space is where the insulation follows the slope of the roof to give a habitable roof space however the insulation is slotted entirely between the rafters. See similar questions...

Provided the building meets the minimum insulation standards as laid down by current Building Regulations, Radiant UFH will provide full comfort conditions. Floor temperatures will not normally exceed 29°C which means that the floor will feel comfortable. See similar questions...

Layers! Good thermal underwear close to the skin and a suitable selection of thin layers under a windproof outer garment. For serious extremes a hooded down jacket and padded trousers are welcome. Summer in the arctic or Antarctica doesn't require nearly as many clothes, but you will need a windproof outer layer and good insect repellent for the sub Arctic. See similar questions...

It depends on the type and size of the greenroof. Most homeowners could check a flat or low pitch greenroof. A roofing professional should if it is too large or intensive – you can include a maintenance agreement of at least twice per year with the greenroof contractor/greenroof company. Or you can work out an arrangement with the roof maintenance staff of your building. See similar questions...

Yes, although we do not recommend the application of our product by a novice do-it-yourselfer. By following our detailed installation instructions, an experienced do-it-yourselfer can install Springhouse Shingles with relative ease. See similar questions...

with most roofing products, the best installation comes from tearing off the existing roof. This is what we recommend for DaVinci products. However, it is not a requirement. DaVinci Slate and Shake can be laid over an existing roof if the situation meets generally accepted industry criteria and local building codes. See similar questions...

A Roof-Over is when the new shingles are placed over the old ones instead of tearing off the old ones down to the roof deck (wood). This practice is allowed by most communities "ONCE" or one layer on top of the original layer, mostly for financial reasons for the homeowner in an emergency situation. The reason why this is not recommended is that for one; the shingle manufacturer will not warranty a roof over, and any trustworthy Roofing Company will not warranty a Roof-Over.

Depends on the individual, but most hikers find that a down or synthetic bag rated at +20? F is a good compromise between warmth and weight/bulk. You might choose to add a VBL (vapor barrier liner) at Kennedy Meadows in early season for the high Sierra, or a 5? F bag. Otherwise you will probably be a little chilly at times. Most hikers carry a light sleeping pad, but some insulate themselves from the ground with only clothing and gear. See similar questions...

Wind is the biggest factor in water temperature. When the wind blows from the ocean towards the land, it blows water that has been warmed by the sun towards the beach. When the wind blows from the land towards the ocean, that warm water is push out to sea, and the cold water from underneath rises to take its place at the shore. The warm water is clear because its on the surface, while the cold water that was on the bottom is full of sediment and is a murky brown. See similar questions...

Probably (this is in reference to the underwater temperature readings we provide on the ReefCam pages). The underwater temperature probe we use is reasonably accurate, but we've found that water temperatures in the shallows can vary by several degrees Fahrenheit. Use the number as a relative measure and you'll be fine. Water temperatures at diving depths on Bonaire range from about 77 to 87 degrees Fahrenheit. See similar questions...
