Product Description
ThresTite™ Door Threshold Gasket System is a permanent gasket seal designed to eliminate air and moisture from entering slab-on-grade door thresholds. Made from closed cell cross-linked polyethylene, ThresTite has the ability to compress and re-adjust for a permanent perfect fit during construction and when the building settles or moves. This peel and stick product uses Weather Bloc's high performance MicroGrabTM Adhesive Technology that allows adhesion in extreme cold and wet weather.

Seal Those Leaky Doors - Permanently!
One of the largest consumer complaints in construction is drafty doors. Air getting through the threshold and causing discomfort is that major cause for customer dissatisfaction. For years, contractors have used caulk as hopeful solution but it has failed miserably.
This infrared scan illustrates the amount of heat loss at the threshold of this door. This not only causes drafts but cost 100's of dollars every year in energy loss.

Basic Uses
Additional Benefits
Can be used under door thresholds with slab-on-grade or wood construction. This product can be used anywhere a gasket is needed.  
Easy Start Peel and Stick™permits a quicker release of the backer that provides faster installation.
By examining thresholds from different door manufactures, one will notice that they are extremely difficult to caulk. The other factor is the unevenness of the concrete and stiffness of the threshold making the sealing uneven as well. The real long-term solution is Weather-Bloc's ThresTite gasket. With Peel and stick for waterproofing and cross-linked polyethylene for that rebounding type memory foam give ThresTite a permanent threshold seal.
This product will stay Flexible Forever giving it the advantage of moving with the expansion and contraction of the building.
Can be installed successfully at temperature as low as -30° F.
By not allowing air and moisture to enter into the building envelope, one can save up to 50% on utility cost.
