All Spa Covers are Not Created Equally

DuraTherm spa covers 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.

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.

Quality Features & Craftsmanship:

Premium Vinyl Outer Skin
What You See

High grade vinyl 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. UV inhbitors

Closed-Cell EPS Foam Core
Ideal Taper for Water Run-off

Special EPS virgin foam insulation We use thicker closed-cell aquatic grade virgin EPS insulating cores with better R-value and moisture resistance. Some cover makers use cheap 3.5" construction-grade foam or taper down to just 2" thin-- not a good idea.

See Upgrade Options


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. Steel reinforced spa cover

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

Special heat-shrink vapor barrier 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. Zipper access to core
   

Double Ply Matching Handles & Other Details

Matching handles 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

Safety tie down straps 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. Skirt or apron length
gussets for proper fit 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
Super insulated, and reflects heat back into water

Heat reflective Mylar underside

Large Photo

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.

heat reflective shield in spacecraft 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. double vapor barrier spa cover liner
Vapor Shield 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)
 
2 lb. core upgrade

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. 

High density foam for snow load

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).

Heavy duty 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.
