But what about the wet and windy wintertime? How do those large frames cope with the cold and moisture? It all comes down to wind and water tightness. Wind tightness and water tightness are two of the most important factors that determine the quality and living comfort of your building. A waterproof and windproof home offers you several invaluable benefits: - Little or no draught gets inside. Our standard aluminium doors are windproof up to wind force nine, being a storm. Tilt-and-turn windows up to wind force 11. - Even in heavy rain, your home will be protected from water seeping through. - Reynaers Aluminium windproof profiles offer excellent thermal insulation. Build an energy-efficient home that withstands both heat and cold, all year long. ![Detail view of concealed drainage in a black aluminium window.](/sites/default/files/public/styles/landscape_full_width_wide/public/2022-05/Reynaers-Aluminium-water-tightness-3.jpg?h=61f1cca7&itok=NC53nnGD) ![Detail view of sprinkler performing a water tightness test.](/sites/default/files/public/styles/landscape_small/public/2022-03/Reynaers-Aluminium-water-tightness-2.jpg?h=7721ddbf&itok=aY6AMPzM) Share this story - [f](https://www.facebook.com/sharer/sharer.php?u=https%3A//www.reynaers.com.au/markdownify/node/6300%3Futm_source%3Dfacebook%26utm_medium%3Dsocial%26utm_campaign%3Dwebsite) - [t](https://twitter.com/intent/tweet?text=https%3A//www.reynaers.com.au/markdownify/node/6300%3Futm_source%3Dtwitter%26utm_medium%3Dsocial%26utm_campaign%3Dwebsite) - [l](https://www.linkedin.com/shareArticle?mini=1&url=https%3A//www.reynaers.com.au/markdownify/node/6300%3Futm_source%3Dlinkedin%26utm_medium%3Dsocial%26utm_campaign%3Dwebsite) - [p](https://pinterest.com/pin/create/button/) - [m]() ## You might also like [ See all stories ](/stories) - ![Girl entering white house via fingerprint scanner technology.](/sites/default/files/public/styles/teaser_medium/public/2022-03/Reynaers-Aluminium-smart-building-3.jpg?h=35756bb6&itok=BCbyUfqr) ### Turn your house into a smart home with Reynaers Aluminium [](/inspiration/stories/turn-your-house-smart-home-reynaers-aluminium) Read this - ![Interior view of penthouse apartment featuring HiFinity sliding systems.](/sites/default/files/public/styles/teaser_medium/public/2022-03/Reynaers-Aluminium-sliding-doors-2.jpg?h=16a6ccf5&itok=Ao4fZcFv) ### The right sliding door for your building project [](/inspiration/stories/right-sliding-door-your-building-project) Read this [ See all stories ](/stories)
