Still Hand Stapling and

Nailing With No Caps?

Think Again.

Collated cap staples and cap nails have swept

the home building industry, oering dramatic

performance and time-saving advantages. Ask

any contractor what the biggest problems are

when applying roof underlayment, and especially

housewrap, and most likely you will likely get the

same two answers every time.

First, there’s nothing more annoying than stapling

up a piece of underlayment or housewrap, only to

have the sheets peel o in a sagging, drooping mess,

sometimes tearing in the process. It takes three,

sometimes four guys, to hold and get back on track

the underlayment or housewrap to be re-stapled.

Installing housewrap on a windy site is even worse.

Underlayment or housewrap makes a great sail, as

you have surely noticed. On a windy day, it seems

that no matter how many staples you apply (often

they are tacked in by the hundreds), nothing can

keep the underlayment or housewrap from billowing

up in the wind and blowing away like a balloon in the

Macy’s Day Parade.

Secondly, any contractor who has installed an

underlayment or housewrap will wonder why, with

all the other advancements in home building, we’re

still ﬂailing away with the antique “technology” of

hammertackers. There are still underlayment and

housewrap installation contractors out there who use

hammertackers today, pounding in staples every few

inches, guessing how many it will take to hold the

underlayment or housewrap in place long enough

to be pinned down by the corner boards, siding, or

rooﬁng.

Additionally, hammering in all of those staples is

just an aggravating waste of time. The holes they

create in the underlayment or housewrap actually

compromise the ability of the underlayment or

housewrap to perform as weather resistant barriers.

If your housewrap application allows water to seep

through hundreds or even thousand of holes caused

by stapling, the water can get trapped between

the housewrap and the sheathing, creating ideal

conditions for rot and mold, which can grow in

temperatures above 40

F and wherever humidity

climbs above the 20-40% range. If you’re killing your

wall’s performance with “death by a thousand cuts”

(pin-prick staple holes), it can have a lasting negative

impact on the building envelope, and even the life of

the building itself.

Make no mistake, those staple and nail holes really do

add up to meaningful gaps in the housewrap when

you calculate their collective impact. TYPAR recently

engaged a third party in a study of water holdout and

air inﬁltration. The study compared the performance

of housewrap that was stapled in place to housewrap

that was fastened with cap nails or cap staples. No

surprise: The structure that used cap nails and cap

staples to attach the underlayment or housewrap

performed markedly better in resistance to air

inﬁltration and water holdout. The reason is clear.

Caps sealed up the holes made by the penetration

of the fasteners, so let’s take a closer look at capped

nail and capped staple application systems.

A Revolution in Fastening

With all the advances in fastener tools, isn’t there a

better way to attach underlayment and housewrap

besides stapling it in place, and leaving behind all

those holes? Indeed there is.

Continuing in its tradition of innovation, TYPAR® has

partnered with National Nail Corporation to deliver

a full line of fastener tools specially designed for

attaching underlayment and housewrap, without

leaving behind thousands of unsealed staple holes

or nail holes. National Nail and TYPAR accomplish

this through the use of cap fasteners. National Nail’s

STINGER® Cap Systems oer contractors pneumatic

and non-pneumatic tools where every nail or staple

is automatically driven through a small, circular 1-inch

plastic cap that eectively seals the holes created

by the fastener. The caps are concave in shape, and

when the fastener (nail or staple) penetrates the

cap, it puts the concave structure in tension, thereby

forming a perfect seal. With the STINGER system, the

fasteners and caps are delivered in collated strings,

just like collated nails in a framing gun. As you drive

the staple or nail, the cap is automatically fed into

position, a marked improvement in productivity over

nailing capped nails in one at a time.

A Revolution in Flashing (Cont’d from cover) In addition to solving the problem of compromised underlayment and housewrap performance, the cap and fastener combination – which come in 3/8, 5/8, and 1-inch fasteners – has twenty times (20X) the holding power of staples! That kind of holding performance will put to rest any concern that underlayment or housewrap will peel off under its own weight or blow off in the wind.
