sequence of roofing materials, for flat roof?

By LiamK

I’m a newbie, working on a shoe-string to gut and salvage the small 1950s house I inherited, but with no cash to “do it right.” It is either make-do, or lose the house. It will be torn down whenever it is sold, and a McMansion built.

I have a question on recommended roofing materials for the flat roof, and their sequence. The roof is flat and is 32 squares (including shop and carport), in the rainy Pacific Northwest. Does the following sequence make sense? Or is the sequence wrong? Can I cut anything, to save money? Anything I should add, like Tyvek/Typar — if so, where?? From the top down:

* membrane (probably PVC; or torchdown)
* #30 roofing felt
* peel-stick water-and-ice barrier [GAF or Grace or ??]
* [possibly 1″ XPS rigid foam insulation if I can afford it, to insulate and smooth any rough old deck; R5]
* old tongue-and-groove wood decking (on drip-edge replaced 4′ in, and as needed)
* 2″ airspace
* 5.5″ Roxul rock-wool insulation R22 [more mold-resistant than fiberglass]
* drywall ceiling (probably paperless-drywall, to limit mold; DensArmor or ??)
* latex paint (Kilz II primer)

It’s a very flat roof, a 1:16 slope (too flat) that leaked on and off for years, so there was a very serious mold problem (requiring a complete gut inside of all drywall and trim). I need to tear off layers of old build-up (hot-tar) roofing, and repair parts of the deck, and fix some joists/rafters that are rotted for 3′ on the drip-edge. I’ve read lots of debates about torchdown vs PVC membrane. I’m currently leaning towards PVC, despite the higher cost, as its safer for me to install myself (no flame), and white is better in summer (I’ve no A/C). I worry about condensation if I use PVC, though I’ll add at least two 2-way vents (kitchen and bath) and the soffits have vents.

I really appreciate any sound advice, especially from those who’ve been around long enough to see fads come-and-go. Many thanks in advance!

Tile floor over EPS subfloor?

By Philosopher

I am renovating my basement and insulating the cement slab floor. I am laying down XPS Rigid foam insulation on the concrete and attaching 1/2 plywood directly to the floor with anchors and using biscuits on the joints. This method is discussed, by the way, in the latest Fine Homebuilding by Martin Halladay and discussed more fully here http://www.buildingscience.com/docum…g-your-basment

Anyway, it’s preferable to use 3/4 T&G but for various reasons the 1/2 worked better for me. I did not use sleepers, but have anchored the 1/2 plywood directly to the floor. I have also insulated a small 1/2 bathroom (4×6) this way. Everything is going very well. I will lay bamboo on the rest of the floor, and had thought I would do so with the bathroom, but now that I have been walking on the floor and seen how study and solid the XPS is when attached this way, I am starting to thing that it may be possible to lay down some 1/2 cement board and lay some tile in this small bath. I have tiled 2 other baths, and would prefer tile in this basement bathroom as well.

So, having heard all that, is there anyone out there who has tiled over XPS/plywood floors? Is it possible? Will it crack? I honestly can’t see how there would be any flex in the subfloor. When it is all in place with the anchors and the biscuits, it is very tight and solid. But I don’t know how to attach the cement board to the plywood, since it doesn’t seem like there’s enough plywood to hold the screws. Does anyone have any thoughts? Anyone done this sort of thing or worked with tile on this?

Any advice would be very appreciated. Thanks.

Prep for remodel

By tommyxv

I just finished gutting my basement. It was mostly paneling attached to furring strips, and some was 2×4 walls right up against the concrete with fiberglass batts.

The area is conditioned space. Luckily there was no mold. The house was built in 1970, I have poured concrete foundation walls.

I was given a new unopened 5 gal bucket of drylok yesterday. Should I paint the walls before I glue the 1″ XPS to it? Will it cause any problems?

I plan on doing my framing with metal studs since I got about 40 studs for free. I was going to put a sill gasket down first, then PT base plate, then another gasket to keep the metal track from touching the PT plate. Does that sounds ok?

Dell remains committed to Windows RT

Dell remains committed to Microsoft’s Windows RT, despite the poor market reception to the OS and a decline in prices of related tablets.

The company has “future generations” of its XPS 10 tablet, which runs Windows RT, under development, said Neil Hand, vice president at Dell.

The upcoming tablets will be lighter and faster, though Hand did not provide any further details on release dates or specifications of the XPS 10 successor.

Microsoft shipped Windows RT for ARM-based devices and Windows 8 for Intel-based devices in October last year. The XPS 10 was released to positive reviews shortly after, with prices starting at US$499. The tablet now starts at $449, and Windows RT tablets are offered by Samsung, Asus and Microsoft, whose Surface RT starts at $499.

1 Big Reason Why Icahn, Others Might Be Overpaying for Dell

By Tim Beyers, The Motley Fool

DELL Revenue Quarterly YoY Growth Chart

Filed under:

Carl Icahn can’t seem to stay out of the headlines. The one-time Netflix agitator and mortal enemy of fund manager Bill Ackman is now knee-deep in what has become a low-grade bidding war for Dell .

I’m mystified, though, as to why Icahn or anyone else would want a piece of the PC maker. Dell is missing out on the greatest growth opportunity we’ve seen in more than a decade.

Tablet troubles
Some won’t agree with that take, especially those who say that tablets are, in effect, PCs. They’re the just the new “form factor” — what the computer has morphed to be, these cheerleaders say, arguing that an uptick in tablet sales favors Microsoft and Intel at least as much as Apple and Google .

Nonsense.

If the categories really were so indistinct, then Dell would have no reason to sell itself to the highest bidder. Just sit back and roll in the giant piles of cash built from sales of the XPS 10 tablet and the relatively new XPS 12 convertible, which earns good reviews from the likes of CNET and Engadget. These are the sorts of Windows 8 devices that will  boost the whole PC sector, right?

Source: CNET.

PC fumbles
Wrong. Manufacturers haven’t seen a boost of any kind. Intel’s first-quarter guidance came in below consensus due to weak PC demand. Microsoft reported good Q4 results in its Windows division, but on a comparative basis, Windows 8’s launch quarter brought in about $1 billion less than Windows 7 did at the time of its introduction. Taiwanese manufacturer Acer recently said Chromebook sales are on the rise while characterizing Windows 8 as “still not successful.”

Dell, too, is showing battle scars. The one-time PC king suffered an 11% decline in revenue and a 22% drop in adjusted earnings per share in Q4. Both figures nudged ahead of estimates, revealing just how pessimistic Wall Street‘s view is of this business.

Analysts have good reason to be wary. Q4’s results continue a downward pattern that’s been in place for years and that shows no signs of abating:

Tabbed out
In its 10-K annual report, Dell cites the “mobility” business as one of its weakest. Sector revenue declined 20% on an 18% drop in units sold. Average selling prices also fell 2%.

During Fiscal 2013, we experienced a difficult pricing environment for our client products. In particular, demand for our client products in emerging countries was affected as we saw a migration to lower-value offerings, where we are less competitive. Our results were also affected as customers shifted some of their demand to alternative computing devices, particularly in our Consumer segment,” the report confesses. [Emphasis added.]

Translation: We aren’t good at selling smartphones and tablets, which is a problem when you consider how important these devices have become:

Dell XPS 18 Hits Size, Weight and Performance Trifecta

  • World’s thinnest and lightest All-In-One starts at just 4.85 lbsi for maximum portability; just pick it up and go!
  • Large 18.4-inch Full HD capacitive touch display opens doors to new ways of working and collaborating

ROUND ROCK, Texas–(BUSINESS WIRE)– Dell today raised the bar on computing with the announcement of the XPS 18, a design breakthrough that achieves a perfect blend of weight, large display size and performance in a thin, elegant and highly mobile design. With a huge 18.4-inch Full HD capacitive touch display, the XPS 18 opens up new possibilities in multimedia and casual gaming for families, yet is still easy to use thanks to its surprisingly light weight. In addition to its innovative design, the XPS 18 hits the much sought after sweet spot between mobile entertainment and desktop-level productivity, and dramatically redefines beliefs of what a PC can do.

Built with families and active consumers in mind, the XPS 18 is the world’s thinnest, lightest and most portable AIO, and can be easily transported around the house for watching movies in the living room, playing games with the family, viewing recipes in the kitchen or creating professional presentations in the home office. When it’s time to move the XPS 18 into another room to do homework in a quiet environment, its slim and lightweight design make it so portable a child can carry it.

The XPS 18 boasts a number of competitive and industry firsts that set a new standard for AIOs. Starting at just 4.85 lbsi with an optional SSD drive, the XPS 18 is less than half the weight of other currently available portable AIOs and has nearly double the battery life offering up to five hours of run time between chargesii. The 18.4-inch Full HD touchscreen is over three times the screen size of the Apple iPad (nearly twice the diagonal) and lends itself to new ways of sharing a computer and collaborating on a single device. It is light enough to hand back and forth, but the screen is large and vibrant enough for multiple people to watch videos, share content or enjoy dual-player games on the same screen from a variety of angles. The XPS 18 is based on third-generation Intel Core processors and Windows 8 operating …read more

Dell's XPS 18 All-In-One Doubles As 18" Windows Tablet, Weighs Less Than 5 Pounds

By Jason Evangelho, Contributor

Just as Windows 8 has inspired a new breed of hybrid ultrabooks and tablets, Microsoft’s latest OS is making waves in the All-in-One PC space. Dell has just pulled back the curtain on their XPS 18, an All-in-One (AiO) that doubles as an 18″ Windows 8 tablet. …read more

Dell's new XPS 18 all-in-one doubles as tablet and a PC

Dell Wednesday introduced its versatile XPS 18 PC, an 18-inch all-in-one PC that can double as a supersized tablet.

The XPS 18 runs Windows 8, and with a large touchscreen, has the look of a mammoth tablet. At nearly 5 pounds, the machine is not highly mobile, but it is easier to carry around than typical all-in-ones.

The XPS 18, whose pricing starts at $899, also has a battery and functions as a tablet when detached from a power outlet. In tablet mode, the device provides up to five hours of run time on a single battery charge. Two stands that pop out on the back provide balance when the all-in-one segment rests on a table.

The announcement comes as Dell’s commitment to the PC market is under question as the company pursues a leveraged buyout. Dell announced in early February it was being purchased for $24.4 billion by founder Michael Dell and equity investor Silver Lake. The deal, which is subject to shareholder approval, includes a $2 billion loan from Microsoft, and debt financing commitments from a group of banks.

Review: Dell XPS 10 Tablet (32GB, keyboard bundle)

The Dell XPS 10 Windows 8 RT convertible tablet sports an innovative design that features batteries in both the tablet and dock. When the two halves are
married, the XPS 10 delivers a stellar 16 hours of run time–a major selling point if you’re commuting internationally. The unit is also handsome in a
sedate fashion, and tactilely appealing thanks to Dell’s soft touch paint on the exterior. On the down side, the display’s 16:9 aspect ratio is less than
optimal for reading, performance is so-so, and the keyboard and touchpad aren’t Dell’s best.

From great battery life to sensational battery life

Our $629 ($399 without dock) configuration of the XPS 10 had 2GB of system memory, a 1.5GHz Qualcomm Snapdragon S4 CPU, and 32MB of eMMC NAND storage. In conjunction with the dual 27 watt-hour batteries the components delivered superb battery life–8 hours and 20 minutes for the tablet solo, and 15 hours and
50 minutes when docked. Yowser. 64GB models are available for $679/$499.

Judged subjectively as a tablet, the XPS 10’s performance isn’t bad, and it posted average scores in our Web-based performance tests However, as a laptop,
which is arguably the unit’s most useful state, it feels just a tad sluggish. Most of the lag occurs when you open programs, switch pages, etc. These are
usually symptoms of a slow hard drive, and the eMMC’s relatively low 80MBps read and 20MBps write speeds would seem to bear that out.

Dell's 'Sputnik' Ubuntu Linux laptop gets a key upgrade

Although it’s oriented primarily towards developers, Dell’s “Project Sputnik” Ubuntu Linux ultrabook has attracted considerable interest from Linux fans.

When I spoke with Barton George, a Dell director, upon the North American launch last fall of the XPS 13 Developer Edition, he noted two common requests that came up during the testing process: a “big brother version” with beefier specs, and availability outside the United States.

Earlier this week Dell offered fresh news on both of those fronts.

“On Dell.com, we’re now offering the XPS 13 Developer Edition laptop with the full HD screen for customers in the United States for $1549,” wrote Dell blogger Lionel Menchaca on Monday. Not only that, but “we’re also starting to roll it out in select countries in Europe.”
