TECH TIPS —
Control costs and protect your work with ® SOLITEX EXTASANA pro clima SOLITEX EXTASANA® wall underlay BRANZ appraised for up to 180 days exposure to the elements in New Zealand. The TEEE, monolithic, non-porous, vapour permeable wall membrane from pro clima keeps your hard work dry from driving rain and protected even with harsh UV exposure for longer. Rain or shine, you’re safe for up to six months! A South Auckland builder, Bruce, recently struck a problem when a heavy downpour soaked his framing even though the frames had been covered with a building wrap. Bruce had to fork out a lot of money and lose a heap of time to hire dryers to dry the frames so that they were at a suitable moisture content for lining. As he is building a multi-unit residential structure, with 10 units, this cost was multiplied 10 times! So why did Bruce end up with wet frames and a huge bill? It could be because he didn’t use a non-porous vapour permeable membrane. A non-porous, TEEE membrane is not affected by being in direct contact with framing and helps keep the water out and your framing dry.
Part of a complete system, pro clima SOLITEX EXTASANA® accessories include TESCON EXTOSEAL® sill tape, TESCON EXTORA® flashing tape and ROFLEX pipe seals. ORCON® CLASSIC adhesive also helps to seal off the wrap to the slab. All these system products are free of chemicals harmful to life and carry the Red List Free label. Bruce recently confirmed that the developer he works for now insists on “Dry as a Bone” SOLITEX EXTASANA® every time! Give the blue wall wrap from pro clima a go. You’ll make your life easier and protect your work for longer just like Bruce and his developer have.
