The ideal solution for a new build or re-roof project is to have insulation between and under the rafters. Ideally it needs a continuous surface for the breathable sarking membrane so that it can be installed in horizontal runs under counter battens with laps sealed. The next best solution is to have insulation between and under the rafters with no continuous surface for the breathable sarking membrane.

Brush off all loose debris and scrape off any large deposits of moss or algae. Apply the solution with a pump sprayer to cool shingles! If the shingles are in sunlight, the solution will evaporate before it can work. Keep the roof surface wet with the solution for at least 30 - 45 minutes. Scrub lightly with a broom or brush and rinse well with water. Try a test section first using just one quart of solution. If it is still stained, boost the concentration to 8 ounces per gallon of water. See similar questions...

No. It's actually a little easier because you can stand right up in the second floor to install insulation....and, depending on the size barn you're building, you can get up to R-90 between the trusses! See similar questions...

We would strongly recommend that you do. Insulating the Underdeck of an exposed roof with 50 mm Thermocole saves nearly 2 Tons of airconditioning. The cooling load with insulation is around 6 Tons. Without the insulation, it would be 8 Tons or 33% more. Not only do you have to pay more initially for larger equipment you will unnecessarily spend money continuously on power.

A sprayed on foam insulation can be used but the preferred method is to place a slightly smaller dome under the main dome. This allows room for insulation, wiring, etc along with an interior view of the roof. See similar questions...

Wouldn't it be simple if there was one answer to all roofing problems? Unfortunately there is no magic pill in the roofing market that solves all roofing problems. What the market does offer is a wide selection of good products, each having attributes and faults. The key to selecting the proper roof system is identifying the specific roof design parameters of your building, and how each roof system meets those parameters. See similar questions...

Many groups use church-provided or rented vehicles. Fifteen-passenger vans are ideal since World Changers works with each group to use their vehicles at the projects. At the project, you will be requested to remove or not use the back seat because of safety issues. No. The participants you bring to a World Changers project must be Christians who are active in your church's ministry. Our approach involves helping participants grow in their faith and develop mission-minded lifestyles. See similar questions...

Unless you are finishing the attic for living space, you should insulate the attic floor to contain the heat within the living space. See similar questions...

with any other investment, first and foremost one must be properly informed. The resources of this website and links to other sites are an important good beginning. A subscription to Infinite Energy, with its careful following of New Energy R&D work, and sudden claims and counter-claims for this and that "device," would be extremely useful (and could help avoid a mistaken investment!).

Many online vendors allow you to download programs and try them out before you buy them. Many of these programs that you can download from the Internet are totally free of charge, while others require small payments if you keep them. A very nice place to download shareware and freeware programs is at http://gfn.tucows.com . Here you can download FTP programs, browsers, utilities, etc. See similar questions...

A plastic pump-up type garden sprayer is a good way to apply CleanRoof but may be rather slow if you do this in a professional capacity. For quicker application, a pre-spray system is recommended. For more information on custom pre-spray systems, please contact us. See similar questions...

A4. The need to identifying your project bid date accurately depends somewhat on stage of the project. We recommend following the logic shown in the diagram linked below. The logic can be described as follows: project initiation and up to 13 months prior to the planned bid month, we recommend you target the first day of the month in which the project is desired to be bid.

The project structure in Simulation Producer takes the form of an .spp file similar to the sequence.qsp file that contains all the settings for a simulation. The main difference is that you can name the project file whatever you want, as long as the extension remains .spp. Note that projects and the simulations associated with them rely on relative paths.

A civic-minded group such as a Rotary Club or local Fire Department can bring a Fire Hydrant Decal Project to your community. Print the brochure for use as a presentation aid to your Rotary Club and the Fire Chief The Fire Chief is the key person. The chief knows the number and location of fire hydrants that should be marked with highly reflective decals. See similar questions...

Congratulations! You're one of the lucky few who has spent the time to research the best way to start. This will surely pay off when you reach the printing stage. There are many options available - depending on your level of design skill and knowledge. To begin visit our Design It Yourself pages for all the information you need to get a great design at any skill level. More information about products and sources for everything from books to software programs is also available to help you. See similar questions...

Our preferred file formats are .aif, .wav or .sd2 stereo. These can be sent to us on CD-R or DVD-R. If your program is in another format, we can arrange to have it transferred at an additional cost. Set the burn speed on your disk recorder to the slowest speed available and use high quality blank disks. We've had good success with disks from Taiyo Yuden and Sony. Leave the disk free of any sort of paper or plastic labels. Please submit digital files in their original wordlength and sample rate. See similar questions...

Down warms without weight. It takes 14 wool blankets to equal the temperature control of one down comforter. Each down cluster traps more air for its weight than any synthetic fiber. Every ounce of down has about two million fluffy filaments that interlock and form a protective layer filled with air that keeps warmth in and cold. Down is wonderfully resilient. You can flatten it and with a good shake it will bounce back to its original loft while providing you with natural warmth. See similar questions...

Yes, but the preferred method is removal. The Uniform Building Code allows two (2) roofs on commercial (flat) buildings and three (3) roofs on residential(steep) buildings. Removal allows for inspection of the substrate, and the elimination of any wet, rough, and/or unstable existing materials. See similar questions...
