DuraTherm custom covers last years longer than
ordinary spa covers. Our design is the culmination of everything
we know about cover crafting. The result is the most
durable replacement hard cover for hot tubs available today,
built to withstand the effects of sun & weather, costing you
much less in the long run. |
All Spa Covers are Not Created Equally
 |
DuraTherm premium-quality custom spa covers
are engineered for endurance and energy savings. Manufactured in
the USA to our strict specifications. The beauty of DuraTherm
spa covers is more than skin deep. See

Sure, there are cheap, inferior-grade
replacement covers for hot tubs on the market, but we will not sell
them. We'd lose a good customer (you) when those covers
failed after a year or two, while wasting your energy dollars.
No hidden
extra charge for home delivery.
Quality Features &
Craftsmanship:
Premium Vinyl Outer Skin
What You See
 |
Our 30 oz. marine-grade vinyl
is manufactured to ISO 9001 quality standards with higher levels
of mildew inhibitors and special plasticizers. It is the
top grade and most expensive
vinyl available.
12 color choices. |
| Contrary to popular belief,
rainy weather does little to harm vinyl. The sun's UV rays do most
of the damage. Our vinyl contains special UV blockers to resist
fading and cracking. Plus, our Cover Care Kit (FREE with 2
or more upgrades) contains 303
Aerospace Protectant for total UV protection. |

Closed-Cell EPS Foam Core
Ideal Taper for Water
Run-off
Zinc-Coated Steel Reinforcement
Not Flimsy Aluminum
| Dual 20-gauge galvanized steel C-channels
provide reinforcement across the core to prevent sagging &
resulting heat loss. We know from long experience that
steel, although more costly to fabricate, is superior to flimsy
aluminum channels, which can and do bend. |
 |
Caution: Although aluminum
reinforcement channels seem to work well when the cover is newly
installed, over time (with repeated opening and closing of the spa
cover) the aluminum will eventually begin to sag slightly. This
results in heat loss around the cover's perimeter. In rainy
weather, water puddles can then occur, which in turn causes more
sagging. Galvanized steel channel is up to 2.6 times more rigid than
aluminum. Note: Some cover makers use inferior thin 22-26
gauge steel.
VaporShield Heat-Sealed Liner
What You Don't See
 |
Our blue VaporShield 604™ liner encases
the entire foam core, providing a water infiltration barrier.
Maintains the core's R-Value much better than ordinary
polyethylene (bread bag plastic) used by other cover
manufacturers. |
 Recommended
 Double-Wrapped
Core
- ideal low cost upgrade for double protection from water intrusion,
the leading cause of premature hot tub cover failure.
VaporShield™ is a
trademark of Gulf Aerospace Polymers Inc.
Zippered Access to Insulating Core
Rustproof - Concealed with Watershed Flap
|
Two commercial-grade zippers (concealed below
the hinge fold) run the full width of each side of DuraTherm
covers. Simply unzip to inspect the core. Our
insulating panels are designed for easy inspection, or removal
should replacement or cleaning ever be necessary. |

Double Ply Matching Handles & Other Details
 |
Special: Four color-matching ultra-strong double ply
top handles are provided with every spa cover, standard. Other brands only offer two handles. |
| As shown (right) DuraTherm covers feature a
super-reinforced multi-layer cover hinge and tubular gasket pads
to block heat escape, plus multiple moisture drains. All
standard.

(4) Locking Tie-Down Straps
For Security, Heat Retention & Cover Protection
 |
Four (4) color-matched, reinforced locking
tie down straps with latches and key are provided.
Warning: Inferior spa cover brands provide
only 2 tie downs, a safety hazard which also subjects
the cover to wind damage, promotes heat loss, and indicates shoddy
craftsmanship. |
|
Skirt & Gussets |
|
| The skirt (or apron) is meticulously sewn
from two layers of vinyl and will be made long or short as needed (minimum skirt length is
1-1/2") or we can make your cover with no skirt. |
 |
 |
High quality DuraTherm covers feature gusseted skirts, as
pictured. (Gussets are carefully sewn sectional skirts, which
appear as slits in the corners). Skirts made this way hang
straighter, fit better, and have less tendency to bunch-up under
the cover when setting it on the spa. |
Important: Poorly-made covers
use one piece continuous skirts without gussets. Requiring less
sewing, they're cheaper to manufacture, but have inherent problems. If the skirt folds under the cover
it prevents an adequate seal to the spa rim, resulting in wasted
energy. Even more important, on hot days sunlight can cause extreme
heat build-up under the skirting of covers without gussets, which
can damage the spa's acrylic. Avoid hot tub covers without proper gussets.

Energy Shield
Heat-Reflective Underside
Breakthrough
Reduces Heating Costs - Equivalent to R-7
Additional Insulation |
Our Energy Shield™ option pays for
itself in heating cost savings in any climate. Rising heat is
reflected back down into the spa water by the special metalized
Mylar® bonded marine vinyl underside, acting like a heat mirror.
 |
This heat-reflective technology was
originally developed for NASA to protect spacecraft from solar
damage. At the low-tech end of the spectrum, Energy Shield™ is
also used as a liner in the special pouches that pizza delivery
shops use to keep their pies warm in transit. It's truly an
innovative enhancement to spa covers. |
Although R-value is not meant to
indicate heat loss reduced by reflection, the equivalent amount of
insulation to equal the heat retention provided by Energy Shield is
about +R-7, depending on water surface area. Heating cost
savings can be substantial.

Double-Wrapped
Foam Core
Vapor Shield 604™ Water Barrier x 2
Highly Recommended - Prevents Waterlogged Covers |
| Adding our optional double
VaporShield 604™ heat-seal water barrier can double the
longevity of your hot tub cover and help prevent water-logging. |
 |
 |
Far superior to ordinary poly liners used by most other
hot tub cover makers. Water-logged spa covers have virtually
no R-value, so prevention of water intrusion is your best
defense for long cover life and energy savings in the long
run. |
In addition, the small dead air space between the two membranes
adds even more insulation value (approx. R-2) similar to a
double-pane window in your home. |

|
|
Load Duty
2 lb.
Core
Higher Strength, Durability, and R-Value
(boosts Standard cover to R16.5, Super-Insulated model to R-24)
|
 |
High Density core provides extra top load
bearing for hot tubs used in snow climates, or anywhere higher
strength is a plus. You'll also achieve increased heat
retention, which may pay for the cost of this upgrade several
times over the life of the cover. |
|
This 2 lb. aquatic-grade foam core is stronger to resist
cracking or fractures, resists water absorption even better, and
enhances the overall life span of a spa cover. A great value. Note: Avoid excessive snow
accumulation on any spa cover. |
 |
Add the Load-Duty upgrade to our thicker Super-Insulated 5">3"
Model for the strongest cover we've ever offered (sometimes referred
to as a "walk-on cover" in the industry).
 |
NOTE: No spa cover should be used as a regular walkway or play area.
5">3" covers with 2# Load-Duty upgrade are generally capable of handling the weight of an
average-size
stationary adult, but to prevent core damage and vinyl
abrasion, it is best to avoid walking or sitting on any spa
cover. Excess snow should be removed. Although some brands make
exaggerated claims touting outlandish weight loads, load
handling cannot honestly be expressed in terms of total pounds.
We won't play that game, because there are just too many
variables in the way weight is distributed across the surface
area. |
