Wall airtightness isn’t just construction jargon; it’s your secret weapon against sky-high utility bills and uncomfortable drafts that make your indoor climate feel like a weather lottery. So, let’s seal the deal and move forward with the best wall construction for airtightness you can get.
The Exterior Defense Squad
When it comes to protecting your building’s exterior, the SIGA Majvest system is your frontline hero. Picture Majvest as the superhero cape your walls never knew they needed, available in three powerful variants to tackle any challenge.
Majvest 200 is your reliable workhorse, mechanically fastened with cap-screws or cap-nails like a well-tailored suit that stays put no matter what Mother Nature throws at it. For those who prefer the “peel and stick” approach, Majvest SA (Self Adhered) makes installation super smooth, though you’ll still need to tape those seams for maximum protection. And when your walls need to brave the elements between rainscreen panels, Majvest SOB steps up with UV resistance that laughs in the face of harsh sunlight.
But what’s a superhero without trusty sidekicks? Enter the SIGA Wigluv family – your precision tape toolkit. Wigluv 60 (2.3″) handles seam sealing with surgical precision, while Wigluv 100 (4″) becomes your corner-turning champion thanks to its ingenious split backing. Need bigger coverage? Wigluv 150, 230, and 300 (6″, 9″, and 12″ respectively) prep your window and door openings like professional gift wrappers.
Don’t forget about Fentrim – the bottom plate specialist that bridges the gap between your sheathing and foundation. With options ranging from 4″ to 9″, plus the heavy-duty Fentrim 430 that demands a 2″ bite on concrete for warranty protection, it’s like giving your building a waterproof foundation wardrobe. ZIP sheathing builders particularly love the gray Fentrim 430 for that bottom plate airtight finish.
The Interior Intelligence Network
Inside your walls, the Majrex system works with the cleverness of a cactus – and we mean that as the highest compliment! Majrex’s “cactus skin” concept features dual permeance, adapting to conditions like a smart thermostat for moisture management.
Your interior sealing arsenal includes Rissan tapes in the same strategic sizes: Rissan 60 for standard seams, Rissan 100 with split backing for those tricky corners, and Rissan 150 for covering larger connections where Majrex meets other materials. Think of Twinet interior as your problem-solving wildcard. Twinet is used to help get the Majrex onto the studs.
