Lack of moisture management has become the leading cause of exterior wall system damage to buildings. Having an adequate drainage plane design and process element and an installation that helps to remove water in walls of structures has become essential and in some instances required by code. Consulting firms that specialize in enclosure performance recognize effective drainage is a key factor of good building design.
Lack of adequate drainage in the wall system can lead to issues as “simple” as paint/stain failure to more complex to remedy problems such as mold, breakdown of the wall materials, and damage to the structural components of walls and floors.
Nonwoven and woven are two different methods of producing the primary fabric material used in a housewrap. Woven material has crossing “threads” while nonwoven is made more like a paper manufacturing process.
The key difference is the method by which the vapor permeability is achieved in the two types. Most woven products tend to require microperforations to allow vapor permeability, while non-wovens do not. Micro-perforations can decrease the water resistance of a housewrap.
Current building science research indicates that the ideal vapor permeability rating is in the range of 8-20 perms. The vapor permeability of TamlynWrap® Drainable Wrap was engineered to fall into the upper level of the range. Perms within the range are acceptable for most climate conditions. Please refer to our “Keys to Moisture Management”.
The substrate material, the “wrap or sheet”, is a two ply product consisting of the nonwoven base material which has a vapor permeable, water resistant film overlaid on to the base product. This bi-laminate product offers great tear strength, and it places the water resistant film at the outer layer to provide the best possible water shedding.
The filaments that are bonded to the base wrap are made from a ridged, noncompressible, polyolefin monofilament material similar to a monofilament fishing line. The filament does not flatten out when cladding is attached.
The filaments, which are 1.5mm in height and run continuously the width and length of the TamlynWrap® Drainable Wrap are designed to provide a solid and strong hold-off of the exterior cladding material away from the “sheet” portion of the wrap, allowing effective, constant drainage.
The regular compressed spaces on the filament allow drainage while providing a constant adhesion of the filament. And TamlynWrap® Drainable Wrap is omni-directional, unlike almost all other “drainable” housewraps. The application savings of the omni-directional product is a valuable cost savings compared to other “drainable” housewrap offerings.
Our product has three specific features that make it better than Tyvek® Drainwrap® and all other “drainable” type housewraps currently available. First it is omni-directional and thus is the most economical to use wrap in its class of products. Second, it has the widest drainage gap on the market at a 1.5mm standoff from the cladding and Third, it provides the strongest most noncompressible stand-off in the drainable wrap market.
TamlynWrap® Drainable Wrap alone can drain moisture very effectively from wall systems. However, many codes and regulations will still mandate a rainscreen system that not only provides drainage but a much deeper air space for enhanced drying of wall components than the 1.5mm stand-off of TamlynWrap® Drainable Wrap. Use of TamlynWrap® Drainable Wrap product does provide the added value of producing airspace behind the commonly used furring/rainscreen products such as extruded PVC, wood or plywood lath strips.
Fiber Cement Planks or Panels, Natural Wood Sidings, Processed wood sidings, Vinyl, Metal, Stucco, Stone/ Masonry Veneer or Manufactured stone, and other approved and recognized exterior cladding products are all acceptable for use with TamlynWrap® Drainable Wrap if proper installation practices are carried out.
Yes, but there should be a second layer of material such as kraft paper or building felt between the TamlynWrap® Drainable Wrap and the scratch coat as is shown in our install diagrams to prevent stucco or mortar from filling the drainage plane of the sheet refer to the stucco installation procedures on Installation Guidelines for Stone and Stucco Application.
As a component to enhance and improve the total wall drainage system TamlynWrap® Drainable Wrap may be used behind the foam board in an EFIS system. On structures using an exterior insulation board wall system TamlynWrap® Drainable Wrap may also provide effective coverage for drainage directly behind the final exterior cladding.
No testing has as yet been conducted using the product as a roof underlayment, so it is not currently recommended for such use.
Even though not code required, use of a WRB is still the “best practice” and provides the highest level of assurance of the most effective wall system. The probable damage to wall systems when WRBs are not used is well documented.
All too often, local codes are lagging behind the industry’s understanding of the most effective process of installation.
Yes, TamlynWrap® Drainable Wrap satisfies the code requirements for Green Building standards.
It is available nationally through a variety of purchase channels. Please contact us toll free at 800-334-1676 or www.tamlynwrap.com for a referral to the closest source to your jobsite.
Pricing varies regionally based on transportation and servicing costs. An exact quote would be provided through your local supplier of choice.
Our 5 foot roll makes an easy one-man installation possible and the ease of handling reduces the buckling, wavy condition that occurs with wider rolls.
Yes, this keeps the one-man installation and handling value intact. The full roll is only 17 lbs in weight and therefore hand manageable at any place on a jobsite.
Gross coverage is 500 square feet and maximum net coverage with a single horizontal and vertical lap is 447.5 Sq. Ft.
Each roll is individually shrink wrapped and has cardboard end caps on the roll. Each roll is barcode labeled and has install instructions included. Pallet packs are normally 42 or 49 rolls per pallet. A full pallet is pickup truck transportable.
For a minimum prepaid order of 616 rolls a custom logo can be added along with the TamlynWrap® logo.
To meet the minimum warranty requirements and to follow best practices, you must use either cap nails or cap staple fasteners to apply the product. Use of the cap fasteners minimizes the potential for the tearing and blow-off that occurs in many applications.
If you are not using TamlynWrap® Drainable Wrap as an air barrier, taping of vertical or horizontal seams is not mandatory as long as you comply with the minimum overlap directions and the product is installed in shingle fashion. Appropriate taping and flashing around all openings, windows, doors, etc. is still required. However, if you are using TamlynWrap® Drainable Wrap as an air barrier installation, all seams and overlaps will need to be properly taped.
The Tamlyn Water Management System has been designed as a complete system that has available all components from Tamlyn directly including XtremeFlashing™ tape, XtremeSeam™ overlap seam tape, and XtremeSealant™ caulk. We are able to assure that the entire system is compatible by supplying all components.
The Tamlyn system focuses on best practices and by installing between the layers, our system maintains the “shingling” flow down the wall that is the correct way to install overlapping materials. It will drain down and out with no barrier shelves along the way.
The Tamlyn Install guide includes the proper steps to be taken to meet air barrier requirements.
It is available with two different levels of warranty.
Option one is a 25 year limited materials and labor warranty. This requires use of exclusively Tamlyn branded products for flashing and sealing during installation and must be site verified by a Tamlyn agent prior to close-up.
Option two is a 15 year basic material only warranty that can be accomplished simply by installing with cap fasteners per our install instructions and using compatible flashing materials from our list of approved acceptable items.
Yes, we require the use of our complete system of products to qualify for the 25 year warranty. This includes XtremeFlashing™ tape, XtremeSeam™ overlap seam tape, and XtremeSealant™ caulk. Our system components are designed to afford the most effective installed system.
