Why is Thermaseal a better system?
Urethane has been used on roofs for years this is why it is an excellent damproofing. Hydrostatic pressure resistant tests confirm it. Most membranes are only 35 mils thick Thermaseal is at minimum a 1 1/2″ thick. The best part however is the insulation performance. Builders have fought trying to anchor ridge insulation to foundation walls. The problem is you cannot nail into the foundation because it ruins the damproofing. Some excavators have had an extra labor hold insulation in place while they backfill. With Thermaseal it is totally adhered to the foundation wall system and is seamless.
