Timber Frame Construction

Kocyk Construction are striving to achieve the following through focusing on the building envelope, paying attention on Construction techniques, within the Building Fabric.

All of our working team are trained in the correct installation of fabrics and continue to receive training in updating new techniques.

Thermal Performance

The insulating effect of a building’s external envelope is normally the most important aspect of its thermal performance, since more heat is lost through the fabric than any other area.

We are aiming to improve on current U-Value regulations, by increasing insulation thickness and improving [through good management] how it is installed.

U-Values we are achieving –

• Walls – 0.18 W/m²k
• Floors – 0.18 – 0.14 W/m²k
• Roof – 0.13 – 0.11 W/m²k 

Thermal Bridging

We are eliminating thermal bridging and cold bridges within the envelope where heat loss is worse. In a well insulated building thermal bridging can account for up to 50% of heat loss. Continuity of insulation is essential.

Areas to focus on:

• Floor junctions
• Window reveals
• Eaves details

 Thermal Bridging 0.05 – 0.04W/m2K

Thermal Bypass

Thermal bypass is the movement of unheated air within cavity’s or through spaces such as underfloor voids and lofts.
It is therefore important to seal cavity’s and ensure that barriers follow the course of insulation in roof voids.

Air tightness

With the installation of an air barrier we can prevent air leakage which results in heat loss.
Particular attention is needed during the installation process as the barrier has to be joined and overlapped at all the relevant junctions.
Design and sequencing of the project is essential in ensuring this.
Buildings can be tested throughout the construction period.
