If you have any enquiries or would like further information on the services or products we supply then please feel free to contact us using the following details.
If, on this web site, there is not enough full colour, detailed information on the art and science of what we do, then please contact us and we will try even harder. We prefer our wood in beautiful houses that lock up carbon for 300 years, not in brochures that end up in land fill. (right on - ed)
Thermo reflective low emissivity vapour control membrane
We use a robust highly reflective low emissivity vapour control layer which provides significant thermal, strength and performance enhancements over conventional vapour control layer materials with the added benefit of a service cavity.
It is a triple ply construction including a tough polywoven core layer with a bright high purity aluminium foil which is pressure bonded with a further polypropylene interlayer.
AHS installs facing into an unventilated airspace, effectively blocking infra red radiation and enhancing the thermal performance of the airspace, and hence the overall U-value of the construction.
We use it as anti-thermal bridging, it has the lowest thermal conductivity values of any solid due to its incredibly high internal surface area (up to 1500 m2/g). Made out of silicates (sand and clay), it is basically a high tech natural product with a very low environmental impact. A factoid for the technophiles: aerogels are highly energy absorbing, capable of capturing high velocity particles in space that would penetrate thick steel.
We use this as a 9.2mm sheathing board. It is developed specifically for the timber frame industry as an alternative to plywood or OSB, and is manufactured from wood chips and forest thinnings.
Moisture Resistant Flooring Grade Chipboard
We use 2 layers of 18mm, T&G glued and taped.
Layer 1 floats on Layer 2 with a glue only fixing to the acoustic membrane for superior acoustic dampening.
We fit a strip layer fitted around the perimeter cassettes to attenuate transmission to the wall panels.
Our chipboard uses 100% or near 100% recycled wood.
Insulation is a complex trade off between cost, environmental impact and thickness. At AHS, we go into this in as much detail as the client wishes.
We are experts with:
Mineral Wool – probably the best trade off between cost and performance. We offer Knauf environmentally friendly mineral wool insulation with embodied energy reduced by up to 70% compared to traditional oil based binders. Made using sand and recycled glass bottles, the insulation does not contain artificial colours or added formaldehyde, resulting in environmental credentials of A+ in the BRE’s Green Guide. The insulation’s acoustic, thermal and fire protection – class A1 – properties are the same as the traditional mineral wool.
Sheep Wool - Thermafleece utilises hollow wool fibres, blended to an optimum density producing first-class thermal and acoustic performance in buildings whilst minimising impact on the environment. Manufactured in the UK using British sheep’s wool.
Hemp, Wood fibre and Cellulose – we offer these as alternatives, each with their own complex of merits and demerits.
Acoustic wide spectrum insulation barrier
We use a 5mm closed cell extruded polymer foam as a high performance and highly moisture resistant acoustic solution.
