LEARN WHY SIKAPLAN IS SUPERIOR


30+ Years of Performance History

Superior Fire Resistance


By Sika Sarnafil, Worlds Most Trusted Thermoplastic Manufacturer
 

IS TPO WORTH THE RISK?

Over the past 20 years, TPO has grown to become one of the most commonly used low-slope, single-ply roof membranes thanks in large part to its low price point. What you might not know is that most, if not all, TPO membrane manufacturers are on their second, third or even fourth generation of membrane formulations due to performance inconsistencies and many are still having issues.

As the most trusted single-ply thermoplastic membrane manufacturer in the world, Sika is dedicated to educating its current and potential customers about the differences between PVC and TPO systems.

TPO IS:

low performance icon
UNPROVEN

20+ years later and TPO manufacturers still continue to modify their formulations to try and achieve the required level of performance. Especially in hot climates and high UV conditions.

caution
WATER ABSORPTION RISK

Need to seal all cut membrane edges (including factory cut edges) to prevent water absorption.

question mark
WATERTIGHTNESS CHALLENGES

Lack of visual “bleed out” during seam welding and the need to wait 30 minutes to probe the seam makes water tightness quality control challenges.

dislike icon
REPAIR PROBLEMS

Aged membranes surface can be difficult to re-weld and/or patch.

problem icon
FIRE RESISTANCE SHORTCOMINGS

Fire-resistant TPO membranes continue to burn after the flame is removed during burn tests.

challenging icon
DETAILING CONCERNS

TPO membranes are stiff making workability insituations such as detailing, cold weather or thickermembranes a potential problem for waterightness.

SIKAPLAN IS:

good performance
PROVEN

Over 35+ years of performance history from Sika, the creators of Sarnafil and the world leader in producing thermoplastic roof membranes.

trustworthy icon
NO RISK

No edge sealant needed to prevent water absorption.

selective icon
WATERTIGHT

Distinct “bleed out” during seam welding and the ability to probe the seam immediately makes water tightness quality control easier.

cost effective
EASY REPAIRS

Ability to repair the aged membrane with new membrane, not an issue.

thumbs up
SUPERIOR FIRE RESISTANCE

PVC membrane is inherently fire resistant and does not continue to burn once a flame is removed.

DETAILING EASE

Sikaplan PVC is flexible and makes detailing easy, even in cold weather or with thicker membranes.

TPO IS UNPROVEN & UNRELIABLE

The latest formulations of TPO membranes have relatively few years of “real world” exposure, so their resistance to heat, UV, and general weathering is still unknown. Early generations of TPO membranes had many performance issues, which led to changes in their formulations. One of the most common problems was TPO failing in hot climates or when exposed to increased UV.

UNITED STATES DEPARTMENT OF DEFENSE UNIFIED FORCES DESIGN CRITERIA-2012 FOR TPO

Thermoplastic Polyolefin (TPO) shall only be allowed on roofs with an anticipated life of 10 years or less.

TPO membranes are a relatively new roof membrane and have seen several reformulations in the past decade. Since they are new, long-term performance is unknown at this time. TPO should be specified with caution and only with 72 mil minimum thickness.
 
If they can't trust TPO's reliability, you shouldn't either!

SIKAPLAN VS TPO FIRE RESISTANCE

Sikaplan PVC, manufactured by Sika Roofing, is compared to EPDM, TPO, and Modified Bitumen roof membranes in a head-to-head "vertical burn test."

SIKAPLAN VS TPO WATER ABSORPTION

Is a roofing membrane's ability to wick water important? You bet it is! Water absorption of a roofing membrane can affect the quality of seam welds and lead to premature membrane failure, among a host of other things. In this water absorption test between Sikaplan and TPO, there is an obvious winner.
