Weather Lock Frame Silicone Sealant
Features and benefits
EVO-STIK Weather Lock is our best ever frame sealant. In fact, when it comes to withstanding extreme weather conditions, no other frame sealant comes close. It's been tested to the extremes to ensure excellent performance in all weather conditions.
The highly flexible, neutral cure sealant is pressure washer tested to 1400 psi at 80oC, meaning there’s no risk of water ingress around the frame. It’s also tested to EN1026 for airtightness – helping to lock cold out and keep heat in.
Weather Lock is CE marked for frame and glazing, and offers excellent mould resistance and UV protection to prevent cracking and discolouration. It’s available in four popular colours; white, clear, brown and anthracite.
