Braemar Passivhaus Green Building Store

Braemar Passivhaus

Braemar Passivhaus triple glazed timber PROGRESSION windows and ULTRA doors
Aesthetics and performance were the main reasons we specified the PROGRESSION windows on the project.  We really like the way that very little of the frame is visible, it makes for a very crisp contemporary aesthetic.

The project was challenging and was not optimal for Passivhaus. Specifying ultra high performance windows like the PROGRESSION range helped us achieve Passivhaus certification on the project.

The PROGRESSION windows were the ideal match for the project. Our client had wanted to work with the Beattie Passive timber frame system and the PROGRESSION windows worked really well because of the installation detailing and being designed to have insulation overlapping the frame.

The windows and doors are great and we and the client are very happy with them.

We have liked working with Green Building Store on the project and we’re really pleased with how the contract has gone – it has been very straightforward with no hiccups.

Green Building Store offers over and above what you get from other suppliers. It is really easy and useful to have all the data ready for PHPP ready to download from the website. We also got support with detailing around the window and door thresholds and how to minimise thermal bridging using Compacfoam insulation.

Working with Green Building Store gives us an added certainty on a project – they want to help you ensure the windows and doors work and perform as required.

An ‘L’ shaped, single storey dwelling, designed and certified to the Passivhaus standard, has just been completed in Braemar, Scotland. The project, designed by Grigor Mitchell and built, using the Beattie Passive timber frame system, by Stewart & Shields was designed within a challenging narrow plot. Green Building Store’s PROGRESSION windows and doors and ULTRA doors were specified for the project.

Design

The house was designed to and has been certified to the Passivhaus standard. It achieved a final airtightness of 0.5 ac/h. It was constructed using the Beattie Passive timber frame system. The long, single storey linear form and proportions of the proposed house are designed to the narrow constraints of the plot, and to reflect the local vernacular architecture. The shorter range at the south end reflects the importance of the southern orientation of the site and is its public face.

The deep overhang also provides solar shading for the large windows and weather protection for the terrace. The palette of new materials has been selected to be high quality, maintenance free. The principal wall finishes are silicone textured render and treated Siberian larch. The roof is finished in natural slate.

“Aesthetics and performance were the main reasons we specified the PROGRESSION windows on the project.  We really like the way that very little of the frame is visible, it makes for a very crisp contemporary aesthetic. The project was challenging in terms of northerly location and a narrow physical site and marginal in terms of compliance with Passivhaus. It was not optimal for Passivhaus. Specifying ultra high performance windows like the PROGRESSION range helped us achieve Passivhaus certification on the project.
