There's a reason tilt and turn windows are so popular with our customers. Once you understand how they work, it makes total sense. Tilt the handle on our P33A and P34A windows one way, and the top of the sash opens inward for quiet, draught-free ventilation: safe, secure, and perfect for everyday use. Turn it the other way, and the whole window swings open fully. Brilliant for cleaning the glass from the inside, and useful when you want proper airflow. If you've got little ones at home, you can lock the handle so the window only ever tilts: ventilation without the worry. Both windows are triple glazed and precision-engineered to custom sizes for every project with: Whole-window U-values from 0.77 W/m²K Full RAL colour palette inside and out Larger, full-height formats available Range of handle styles and finishes available Decorative glazing bars and custom shapes We've been specifying these windows into passive houses and self-builds for years. They're thermally efficient, perform beautifully and elevate your whole project. Drop us a message if you'd like to talk through what's right for your project.

So, what exactly are Aluminium-clad windows?⁠ ⁠ Think of them as a friendly partnership between different materials. The timber on the inside adds warmth, comfort, and natural insulation to your living space, making it cozy and inviting. On the outside, aluminium handles the tough work, protecting the frame from the elements and reducing maintenance worries.⁠ ⁠ Originally, this combination was all about durability, but nowadays, it’s just as much about giving you design flexibility. You can enjoy clean lines, modern finishes, and colours that match your architecture, without compromising the beautiful feel of real wood inside your home.⁠ ⁠ It’s a thoughtful choice for homes that care about both performance and creating a welcoming space.⁠ ⁠ Curious about how they could be perfect for your project?

⭐️⭐️⭐️⭐️⭐️ "Norrsken triple glazed windows and doors were fitted in 2022 when we built a new house. They are superb. One very large patio door was becoming stiff to open. A Norrsken technician visited to make some adjustments under warranty, all perfect again. Excellent product and service." We like getting new reviews. This one from last week's a nice reminder of the incredible job our engineers and Customer Support team do, supporting Norrsken customers across the country.

Our Innova S319 inline sliding door is designed as a two or four-panel door with a larger fixed panel relative to the sliding leaf.

This door is suitable for use in Passive Houses. #slidingdoors #passivehouse norrsken.co.uk/products/slidi…

What happens at a Norrsken showroom visit? Nick takes us through the way we generally start showroom consultations at the new Poole HQ for Norrsken. Every project is unique - so we spent eight months designing and building a space for the team – and our customers – to flourish. Whether you're deep in Passive House specifications, navigating a period property renovation, or coordinating a multi-dwelling development, we wanted somewhere you could properly explore what's possible - without rushing. Have you visited yet?

A familiar design, done properly. Side-hung windows open outward on side hinges, providing a wide opening for fresh air without occupying space inside your home. They offer clear views, easy ventilation control, and secure multi-point locking, all wrapped in a clean, timeless design. Equally at home in traditional properties and contemporary builds, they’re a dependable choice that works effortlessly day to day.

Uninterrupted sightlines. We love the S315A lift and slide door for its sleek versatility, performance, and style. What's your favourite patio door?

We often share a lot of beautiful completed project images. Here's some of the behind-the-scenes work that gets our clients there. Every installation is unique, with its own access requirements, lifting plan and safety protocols. Our teams might be handling products that weigh 300kgs or more, completing three to four installations per week across the country. So how do we ensure each goes smoothly and safely? Meet the install kit box. Each one contains everything our team needs: fittings, instructions, risk assessments, and unique site details tailored to that specific project. Here are all our February install boxes, organised to perfection by Dani in our Operations Team. This is what excellent installations look like before they even begin.

Sometimes, we get to be part of a project that's just... spectacular. When James and Carolyn came to us with the drawings for their gorgeous traditional new build home in Hampshire, we knew their home was going to be special. Now that their double and triple-glazed timber windows and doors are in, we think this might be one of the most impressive homes we've worked on. It's the P31T in all it's glory. We can't wait to see more project photos once the landscaping is complete! What's your favourite part of this home?

Top hung windows are a smart choice for rooms where you want ventilation without compromising privacy. They open outward from the bottom and allow cool air to enter while warm air escapes above, keeping spaces like bathrooms and kitchens feeling fresh throughout the day.⁠ ⁠ Their outward-opening design works especially well in tighter areas and maintains strong thermal performance thanks to reliable sealing and smooth operation.⁠ ⁠ If you are planning a space that needs both airflow and discretion, this might be the window style that fits naturally into your design.⁠ norrsken.co.uk/collections/to…
