Insulation & Air Tightness

FCM 750 floor band is fitted to ensure vapour control membrane (VCL) is unbroken at the floor zone and with a further upgrade of our VCL wall strips (being installed at the internal wall partition to external wall junctions) will prevent air and heat leakage.

Our Panel design allows for the 120mm PIR insulation to be fitted all the way to the wall plate and insulating the floor zone, further lowering the thermal bridging points. 

It is also recommended that a service void is created for electrics and plumbing This is achieved by installing 38/50x50 timber battens prior to plasterboard installation and greatly reduces the need for holes in the new fitted VCL for electrical sockets etc:.


All these products help meet the requirements of approved document Part L.

Our bespoke kits for semi detached houses come as standard to meet robust detail EWT-2 (fully sheathed) at the party wall.  Upgrade the party wall with PWAB and cavity/ acoustic wall insulation.

SilvaFrame Structures recommends that our timber frame kits are installed by a member of the Structural Timber Association, such as SilvaFrame's partner company SC4 Carpenters Ltd, in order to benefit from excellent technical knowledge ensuring that our timber frame is installed to the highest standard and that designed levels of air tightness, insulation, u values, etc. are achieved.

Liz and Bruce's New 2 Bed House

Stress free, economic construction of 'awesome' end of terrace timber frame house

14 October 2013

Testimonial for SC4 Carpenters Ltd, re: Wash Common Newbury

Dear Conrad,

We would like to thank SC4 Carpenters for the efficient, stress free and economic construction of our new two bedroom timber frame home in Wash Common, Newbury.

The groundwork's for the property started at the beginning of May and we were able to move in by mid August. By comparison, a nearby property was having a two storey extension constructed in the traditional manner. The building works started during the same week as our groundwork's and is still not completed. We are in no doubt which method we prefer.

A passer-by commented yesterday that the house was ‘awesome’ and completely blended in with the existing terraced houses.

We would also like to compliment SC4 on their honest communication with us, which enabled us to make our plans without any concerns of late delivery of the project.

We would not hesitate to recommend SC4 & Silvaframe to anybody considering a new build.

Yours sincerely,

Liz & Bruce
