New site – Timber Frame Passive House in Kinvara

Admin — Sun, 29 Apr 2012 17:01:54 +0000

GreenTec Eco Homes are to start work in the coming days at a site in Kinvara, Co. Galway. The house is being built for QE Homes which are bringing a new standard of Kit Homes to the market. QE Homes were not involved directly in the design of this project but have been instructed to adopt their Timber Frame system. The project is typically based on being Formaldehyde Free. The Timber Frame is treated with a natural Borate salt and is constructed without using OSB and Plywood which typically contain formaldehyde in the glues. The walls consist of a product called Paneline and Panelvent, which are wood based products and are free from added formaldehyde glues. Internal finishes are all to consist of formaldehyde free products i.e. natural paints.

Condensation Risk Analysis Reports

Admin — Wed, 08 Dec 2010 20:47:44 +0000

With increasing levels of insulation, the use of impermeable cladding materials and new methods of construction, can often come increased risk of condensation in buildings. Condensation can give rise to a range of problems from surface staining of internal finishes to long term degradation of the structure. GreenTec Eco Homes carry out a condensation risk analysis report on every build-up we use in our dwelling houses to ensure the best possible risk free performance.
